Fall Gardener’s Calendar

Fall Gardener’s Calendar

Spray Bonide All-Season Concentrate on hemlocks to control woolly adelgid.

Spruce up the landscape by planting Flowering Cabbage & Kale, Garden Mums, Fall-Blooming Perennials as well as Trees and Shrubs.

Pick up your Spring Flowering Bulbs now! To make planting easier, use a Bulb-Digger or an Auger.

Apply Hi-Yield Superphosphate now to coax stubborn plants into bloom next year.

Aerate, re-seed and apply Fall Lawn Food to the lawn. Keep grass seed damp; water every day if necessary. You will also want to check for grubs. Increased activities of skunks, raccoons and moles as well as brown patches that peel back easily are an indication of grub activity. Apply granular Sevin or Milky Spore to control the grubs as well as chinch bugs and sod webworm.

Treat houseplants with Bonide Systemic Granules and Bonide Insect Killing Soap now to get rid of any insects before bringing them into the house prior to the first frost.

Clean out garden ponds and pools. Cover with Netting before the leaves start falling.

Plant bulbs. Fertilize with Espoma Bulb-Tone and water in well.

Divide daylilies and spring-blooming perennials, including iris and peonies. Don’t be tempted to prune your spring flowering shrubs like forsythia, azaleas, camellia, holly, lilac, rhododendron, spirea or viburnum or you will destroy next year’s buds.

Dig up summer-flowering bulbs, such as dahlias, cannas, tuberous begonias, caladiums and gladiolus after the frost kills the top growth. Treat them with Bulb Dust, pack them in Peat Moss, and store them in a ventilated area for winter.

Fertilize your trees with Espoma Tree & Shrub Fertilizer after the leaves fall. Fertilize azaleas, rhododendron, and evergreens with Holly-Tone and other shrubs with Plant-Tone. Spray hemlock again with Bonide All-Season Concentrate.

Set up bird feeders. Clean out birdbaths, refill and purchase heaters for the winter.

Clean up and destroy diseased rose leaves and debris surrounding shrubs and perennials. Use a Rose Collar to mound 6-10 inches of dirt around roses to protect from winter damage. Use Rose Cones for complete coverage.

Remove annuals, roots and all, and add to your compost pile, but do not add any diseased material to it.

Cut back perennials unless they feature ornamental seed heads and fertilize with Espoma Tree-Tone. Prune long raspberry and rose canes back to a height of three feet. Clean up your beds and gardens to avoid harboring insects and diseases over the winter.

Pot hardy spring bulbs (anemone, crocus, daffodil, hyacinth, ranunculus and tulip) and place in a cold frame or cool garage (40 degrees) or sink into the ground and mulch. Keep evenly moist.

Update garden records, noting successes and failures, gaps in planting, future planting and landscape changes.

Water all landscape plants well and mulch before the winter cold sets in.

Spray evergreens, azaleas, rhododendron, boxwood and rose canes with Wilt Stop for protection against wind and cold weather.

Holiday Gardener’s Calendar

Winter is upon us. Depending upon the temperatures, there may still be time to finish remaining chores. If you have any questions about the following procedures or products, please come in and see us. We can help you select the correct dormant oil, fertilizer, selective herbicide and frost protection method. We’re always here to help.

General Landscape

Mulch with bark, compost or other local materials to enrich soil, protect plant roots and prevent erosion.
Protect plants from frost and wind.

Houseplants

Perk up tired houseplants by removing dead and dying leaves. Wash under a soft shower in the sink or tub.
Spider mites proliferate in warm dry winter homes. Check for mites by looking for tiny speckles on leaves.
Transplant if roots are growing through the drainage holes or over the pot edge. If you don’t want to move into a larger pot, untangle the roots and cut back by 1/3, scour the pots and replant with new soil.
Remember to turn your plants each week as they begin to grow towards the weaker window light.
For indoor bloom, plant amaryllis, paper white narcissus, hyacinth, crocus and indoor cyclamen.
Popular holiday plants such as poinsettias, chrysanthemums and orchids fill the stores. Check them thoroughly for “hitchhikers” before bringing into the home or spray with household plant insecticide or soap.
Be creative in your arrangements and combine them with metallic painted twigs, pinecones or seashells.
If using a live tree for a “living Christmas tree”, prolong its time indoors by using Wilt-Pruf to reduce the loss of moisture from the needles.

Lawn:

Remove leaves, toys, hoses, etc, from lawns to prevent dead spots.
Apply winter fertilizer, if not already done. The middle number, phosphorus, aids root growth during the winter.
If you have weeds in your lawn, consider using a winter fertilizer with weed control.
Mow one time after lawn goes dormant and before freezing. This last mowing should be 2 ½” tall.
When temps are freezing, stay off the lawn as much as possible to reduce blade breakage.

Vegetables:

Protect cool season vegetables with row covers, leaf or mulch cover.
Mulch beds to enrich and protect from rain/snow erosion.
Review gardening notes and plan next year’s garden.
Test germination rate of leftover seeds, if wanting to use again.
If gardening under lights or in heated greenhouse, start seeds of early spring crops: lettuce, kale, mustard, spinach, and other greens.
Harvest carrots, lettuce, greens and over-wintering crops.

Trees and Shrubs

Stake young trees and vines if needed. In case of a heavy freeze, use Wilt-Pruf or similar product to reduce transpiration of moisture.
Prevent southeast trunk injury, a form of winter freeze damage. Use light-colored tree guards to protect the trunks of young trees for at least two years after planting. After two years, paint the trunks with white latex paint. These two methods prevent the tree trunk from splitting when sunlight warms the bark on side of the trunk.
Fertilize shrubs and trees, if not done already, and the ground is not frozen. This allows roots to absorb when temperatures are above 40° and when spring returns. Granules and spikes provide nutrients effectively and easily.
Prune out dead and diseased tree branches to prevent from falling on roof or pedestrians.

Pruning Evergreens

When choosing an evergreen for your landscape project, it is always best to select a plant that will not outgrow its designated space, crowding out nearby plants or distorting its own shape without enough room to shine. Proper research can help you choose – you should know the ultimate height, width and growth rate of your selection before committing to what may be one of the more costly additions to your landscape. Always choose naturally slow-growing or dwarf conifers for small spaces, bearing in mind how nearby plants and structures may limit available space over time. Fortunately, just about every genus of evergreen is available in a dwarf variety.

That being said, what if the mistake has already been made? We’ve all made it! It is easy to fall in love with a sweet little plant in the garden center that, within a few years in the ground, looks like it could swallow your house. Fear not, there are ways to rectify the situation with proper pruning.

You will need the right tools to accomplish the job:

Loppers
Bypass pruners
Safety goggles
Leather gloves

Pruning should begin in the early spring before the plant’s soft new growth hardens off. Take a close look at your evergreen to determine its branching habit. Pine, spruce and fir trees all have layers of branches that are whorled around the trunk. Arborvitae, juniper, yew and false cypress have limbs that are produced randomly along the trunk.

Conifers with a random branching habit are able to grow new limbs from old, foliage-bearing wood. You may prune this type of evergreen back to this older wood to encourage a more compactly branched habit and keep size down, or to create the desired shape. Whorled branching evergreens are pruned differently, however. They have new growth called “candles” at the tip of their branches, and they really do look like candles with lighter coloration. To promote a more densely branched, compact habit, pinch the candles back by up to half their length before the needles harden off. Never cut into the older wood below the candle, as this type of evergreen does not have dormant buds on the stem that will become new growth. Pruning into old wood will leave a hole in your plant and distort its overall appearance.

As always, we are eager to assist you with selecting the proper plant for any landscape project you undertake and to advise you on proper pruning to keep it healthy and beautiful for many years.

Dealing With Winter Damage

It’s early spring – time to survey the damage that winter has produced. In some areas, shrubs may still be hiding under piles of frozen snow, and could be crushed or compacted. Severed tree limbs may lie scattered across the landscape, and bark may be torn and stripped from trunks. It’s difficult to know what to tackle first, but fortunately, much of the damage is easily correctible.

Repairing Winter-Damaged Trees

When surveying and repairing winter damage, start with your trees – they are generally the most valuable additions to your property. As you survey the damage – broken limbs, torn bark, a tilting trunk – ask yourself “Is this tree salvageable or should it be removed?” If the damage is extensive, or you are unsure about how the damage may affect the tree’s overall health or future growth, hire a professional for a consultation. Replacing a severely damaged tree with a younger one, perhaps a type you like even better, may be the best solution.

If a limb is broken somewhere along its length, or damaged beyond repair, employ good pruning practices and saw off the remaining piece at the branch collar, being careful not to cut into the trunk or leave a stub. Sometimes a fallen limb may strip bark off the tree trunk. To repair this damage, cut the ragged edges of the loose bark away from the stripped area to firmly affixed healthy bark. Nature will take care of the rest. Even if the trunk of the tree is split, the tree may still be saved. For large trees, repairing this type of damage usually requires cabling and bracing done by a professional. If the tree is still young, the crotch may be pulled tightly together and tied or taped until the wound eventually heals.

Repairing Winter-Damaged Shrubs

Shrubs can suffer the same damage as trees, including broken limbs and stripped bark. Heavy snowfall can crush smaller shrubs, and larger varieties may have their trunks or centers split from heavy snow or ice accumulation. Most shrubs are resilient, however, and slowly regain their shape as the weather warms. If branches are bent but not broken, you may tie them together to help them along and prevent further damage from late-season storms. Do not tie tightly and remove twine after about a year. Completely broken branches may be pruned away, but take care to maintain the shrub’s form and balance, keeping in mind its growth pattern so it will not look lopsided or ungainly. Again, if the damage is severe, you may need to replace the plant.

The harder the winter is, the more of a beating trees and shrubs will take. With prompt attention in early spring, however, you can easily undo much of the damage and help your landscape recover with ease.

Choosing a Japanese Maple

We’re certain you’ve heard it numerous times: fall is the best time to buy your Japanese maple. Have you come into the garden center to pick one? Did the varieties overwhelm you? Let us make it easier for you by explaining Japanese maple differences. Then, when you come in, you’ll know exactly what you want.

The species Japanese maple, Acer palmatum, moderately grows to a 20′ by 20′ multi-trunked tree. The leaves have 5-9 finely cut lobes giving them a more delicate look than other maples. Red spring leaves turn to green in the summer and blaze with yellow, orange and red in the fall. All do best with protection from drying winds and hot overhead afternoon sun. During their centuries of use in gardens around the world, gardeners have discovered and propagated those selections with unusual growth habits and bark patterns, as well as leaf color and shape. With hundreds of Japanese maple varieties available at garden centers, we feel a little simplification is in order.

Leaf Shape
The variation Dissectum or Laceleaf Japanese Maple has leaves are deeply cut and finely lobed giving a lace cutout look. These varieties generally grow best in shady locations as the leaves easily burn or scorch. The leaves of non-Dissectum varieties are much less lacy. They resemble the leaves of native maples but are smaller and more deeply cut.

Leaf Color
The leaf color of different Japanese maples also varies. Many have red spring growth changing to green in the summer. However, some retain the red through the growing season. Some varieties have variegated leaves with white, cream, gold or pink. Variegated leaves burn easily in the sun but can revert to all green in too much shade. Green leaves tolerate more sun than red. Autumn is when Japanese maples really put on a show with a riot of blazing colors.

Tree Form
Non-Dissectum varieties grow more quickly into upright forms. Some varieties remain less than 10′ tall but others can grow to 25′ tall by 20′ wide. Laceleaf maples slowly develop a weeping form approximately 8-10′ tall and 8-12′ wide. However, ‘Seiryu’ is an exception, growing into an upright form.

	*Laceleaf (Dissectum)*	Non-Dissectum
Location	More shade	Less shade
Size	Smaller	10-25′ tall depending upon variety
Tree Form	Weeping	Upright
Leaf Shape	Lacy, fine cut	Lobed
Leaf Color	Red, green	Red, green, variegated

Now that you have identified a suitable planting location and the type of Japanese maple you prefer, come see us and let our friendly staff show you the varieties that meet your requirements. Autumn colors are blazing now so this is a great time to make your selection.

King of the Cold: Ornamental Cabbage & Kale

Looking to add interest to the fall and winter landscape? This year, plant ornamental cabbage and kale for bold textures and vibrant colors.

About Ornamental Cabbage & Kale

Unlike most other annuals and perennials, these two hardy plants improve in appearance after a frost or two, which bring out more intense and brilliant colors in their foliage – perfect as an autumn accent or centerpiece plant. Identified by a number of names including floral kale, decorative kale, ornamental-leaved kale, flowering kale and flowering cabbage, ornamental cabbage and kale are classified as Brassica oleracca (Acephala group). Offering unlimited use in the landscape, these plants have large rosettes of gray-green foliage richly variegated with cream, white, pink, rose, red and purple. Kale leaves are frilly edged and sometimes deeply lobed.

While typical ornamental kale and cabbage varieties are easy to find, you can also try more unusual options, including dwarf varieties as well as upright, taller hybrids that can even be used in cut arrangements.

Using These Attractive Plants

Popular in borders, grouped in planting drifts, or planted in containers for the deck or patio, ornamental cabbage and kale typically grows to 12-18” high and wide, depending on the cultivar. Plant these specimens at least 12” apart in an area with full sun that has moist, well-drained soil. Organically rich soil with proper compost or fertilization is best to provide adequate nutrition for these lush plants. Although they are able to withstand light frosts and snowfalls, ornamental cabbage and kale will typically not survive hard freezes and are best treated as showy annuals.

The best foliage color will occur if ornamental cabbage and kale is planted in early fall as temperatures are cooling, or you can sow seeds 6-10 weeks before the first anticipated frost date – just be sure the seeds have sun exposure in order to germinate properly. These plants are usually attractive in the garden until Thanksgiving or slightly later, or in mild climates they may even last until spring temperatures begin to rise. Hint – when the plants smell like cooked cabbage, it is time to pull them out!

While these plants are superficially similar to the familiar cabbage and kale vegetables popular in salads and other edible uses, it is important to note that ornamental varieties are cultivated for color and shape rather than taste. Keep them out of the kitchen and in the garden instead, and you won’t be sorry!

Healthy Soil: Winter Cover Crops

It’s fall and our annual and vegetable gardens are winding down for the season. Now is the time to invest a little extra time and effort to prepare your soil for next year. Whether your garden is large or small, all annual planting beds will benefit from the addition of a winter cover crop.

Benefits of Cover Crops

A cover crop is a fast-growing, low-maintenance crop that can be used to protect your garden and landscaping beds in fall and winter. Depending on the crop you choose, it can provide many benefits to your garden, including…

Stabilizing soil and preventing erosion
Adding organic matter back into the soil to nurture later crops
Adding nutrients to the soil that have been used by previous crops
Suppressing disease that can wither new crops even before they start
Repressing weeds that will take over a garden
Improving soil structure with aeration and better drainage
Encouraging beneficial insects that will help later crops

Recommended Cover Crops

Different cover crops work best in different areas, and the climate, soil type and growing season will help determine which cover crops will work best for your gardening needs. The most popular recommended cover crops for our area are oats, rye and wheat.

Oats
Sow 6-8 weeks before the first hard frost. Planted early, oats will provide a quick covering with the added benefit of providing an early planting time for next spring’s crops. Oats are not winter hardy, but they will grow in the fall and die in the winter, leaving behind nutritious mulch that will easily decompose when incorporated into the soil in the spring. This is a great cover crop choice for low- or no-till gardens. Sow at 2 lbs. per 1,000 sq. ft. for the best coverage.
Winter Rye
Sow 2-4 weeks before the first hard frost. This is a good choice for gardeners who have late season crops and don’t want to cut off that last harvest. If hardened off before frost arrives, winter rye will continue to grow over the winter. Rye is a vigorous grower and can be difficult to turn in the spring, so bear that in mind depending on what crops you will be planting in spring. Sow at 3-4 lbs. per 1000 sq. ft. for appropriate coverage.
Winter Wheat
Sow 2-4 weeks before the first hard frost. Wheat will cover quickly but is not as aggressive as winter rye. Winter wheat is also leafier, making it easier than winter rye to turn into the soil in the spring. Sow at 3 lbs. per 1000 sq. ft. to provide good coverage.

Cornell University provides a tool to assist you in choosing the correct cover crop for your situation. (http://covercrops.cals.cornell.edu/decision-tool.php)

Planting Cover Crops

Before planting a cover crop, clean out garden beds, removing all roots and plant material. Compost all plant matter that is not diseased. Broadcast seed evenly and cover with soil. Water thoroughly when planting and when necessary during dry periods. In the spring, till or fork oats into the planting bed and you are ready to plant. For winter rye and wheat, mow or chop tops 4 weeks before planting leaving cut cover crop on top to dry. Till or fork dried wheat and rye into the bed before planting.

With the appropriate cover crop, you can protect your garden’s most valuable asset – the soil – and be sure it is ready for spring planting.

Rotating Your Vegetable Crops

Whether you just plant a few tomatoes, herbs and some lettuce or an elaborate garden complete with exotic selections of lesser known veggies, you’ll want to rotate your crops each year. All types of vegetable crops – brassicas, onions, legumes and root crops – require a slightly different blend of nutrients and trace elements, even if their light and water requirements are similar. If you always grow your tomatoes in the same place, eventually the soil will become exhausted of the nutrients that tomatoes require the most, and the crop will become weaker and less productive. Meanwhile, another vegetable could easily thrive in that location and its growth would help replenish the nutrients that tomatoes may need in future years. If you rotate crops in and out, you’ll enrich the soil and enjoy larger, more productive, more flavorful harvests.

The easiest way to rotate your vegetables is to use a 3-year plan. First, you’ll need to decide which vegetables you plan to grow, then divide them into these three main groups:

Group 1:
Peas
Beans
Celery
Onions
Lettuce
Spinach
Sweet Corn
Tomatoes
Zucchini

Group 2:
Cabbage
Cauliflower
Broccoli
Kohlrabi
Rutabaga
Turnip
Radishes

Group 3:
Beets
Carrots
Parsnips
Potatoes

It’s all right if you don’t plant to grow vegetables from each group. Simply adjust your rotation plan to compensate, or even consider trying out a new vegetable to complete the rotation and expand the variety of your garden.

Next, draw a plan of your garden and mark where each group of plants will go, keeping in mind the light and watering requirements of different varieties. It may help to sketch out the boundaries of each group, noting which plants are part of which rows, boxes, containers or beds. Keep those notes and sketches in your garden journal, and also take notes throughout the growing season about which plants perform best and which may be struggling. Next year, move the plants accordingly to shift where different crops are located. If you choose to add new vegetables to your garden, start them in the location with their appropriate group and bring them right into the rotation scheme.

As you rotate crops each year, you will notice consistently lush, healthy plants, bountiful harvests and delicious produce. After a few growing seasons, rotating your vegetable crops will be second nature and will be an important part of your gardening plan to ensure only the best comes from your garden.

Size Up Your Site: A First Step in Planning Your Landscape

Whether you plan your garden from start to finish or use a professional designer, a few simple steps can help you assess your property’s potential to develop the landscape of your dreams. By getting involved in the landscape design process, you can address practical problems, structure your outdoor living space and develop a plan that will reflect your taste and lifestyle.

Surveying Your Site

Every yard, garden and landscape site will have differing light conditions, grade changes, varying soil conditions and existing plants and structures to consider when planning changes and expansions. Using a loose-leaf binder, take notes on each of the following:

Overall:

What are your favorite spots in your yard and why? What your least favorite and why?
In landscapes, do you generally prefer open on enclosed spaces?
What existing plants do you want to preserve, and which do you want to remove?
What is the architectural style of your home? What is your decorating style?
Are you planning any additions to your home that may take away yard space?
Do you want special areas for children, entertaining, pets, recreation, vegetable gardening, water features or composting?
What is your time frame? Do you want a short-term or long-range plan?
Which building materials do you like – brick, wood, stone, pavers, etc.?
Is your outdoor lighting adequate for your use?
Do you need to screen an area for wind, noise or an unwanted view?
What is you landscaping budget (both short- and long-term)?
How will your landscape use change over time, such as when children grow up?

Specific Areas:

What is the light condition of the area? How does it change seasonally?
How is the soil – well-drained, poor, heavy clay, poorly drained, etc?
What are the dimensions of a confined area that could affect plant size?
What are your favorite plants or types of plants?
Would you like a garden accent or other feature in this area (trellis, arbor, sculpture, bench, pond, etc)?
What is the pH and general condition of the soil?

Once you have taken adequate notes, you’ll have a much better understanding about the overall layout of your landscaping site. This can help you plan the best options without making costly or time-consuming mistakes, such as planting the wrong tree that will outgrow a corner in a few years, or choosing building materials that won’t stand up to your climate.

More Tips for Landscape Surveying

You can never have too much information at your fingertips when you are surveying your site for landscaping changes. More techniques that can give you all the information you need include…

Photographing your property. Snapshots can reveal what the eye may overlook, and can be useful to show others to get their unique perspectives. Take views from your house and various areas of your property. Include photos from different times of day.
Measure everything and mark it on a map. You can use graph paper to create a simple sketch that will show dimensions so you can properly size your landscaping plans.
Make a sketch that shows what is existing (plants & structures) and where it is located. This will help you figure out what features you want to preserve, what you may want to expand and what you would rather remove and how the space will change.

Spruce Up for the Holidays

From the Fir Family come some of our most beloved Christmas trees, the Colorado, Norway and White Spruce varieties. Both the Colorado and Colorado Blue Spruce have a nice pyramidal shapes with strong limbs that can hold heavy ornaments or light strands. The Colorado Blue is set apart by its stunning steel-blue foliage. The Norway Spruce has short, soft, deep green needles and the White Spruce possesses a robust full form. Both the Norway and White Spruce should be purchased planted in containers or balled and burlapped as they tend to lose their needles quickly when cut.

Beyond the holidays, spruces make a lovely addition to any landscape. When viewed in the northern forests, these majestic, needled evergreens are glorious with their graceful, symmetrical, conical forms. Smaller landscapes may also enjoy the merits of this genus with the many slow-growing and dwarf cultivars that are commonly offered, many of which are also ideal when selected as living holiday trees. Larger spruces work wonderfully planted in a row as a windbreak but shine equally as well when chosen as a specimen plant. Added benefits include deer resistance and salt tolerance.

Caring for Your Living Christmas Tree

If you do opt for a bagged, balled or potted spruce, there are certain steps you need to take so they can survive the rigors of the holiday and be ready for planting.

Only leave a live spruce tree inside the house for a maximum of 5-7 days.
If possible, place the tree in a garage, carport or sheltered area to help acclimate it to a warmer location before putting it into the house. Keep the root ball moist.
Before bringing indoors, spray the tree with Wilt-Pruf to help keep it from drying out.
Place the tree in a tub of 2 inches of water and cover with newspaper or mulch to retain moisture.
Place the tree away from heating vents, wood stoves and baseboard heaters.
Check water level daily and refill as needed.
Prepare your planting hole outside by digging it early and covering with plywood until needed. Store soil in the garage so it does not freeze.
If possible, acclimate the tree once more by putting it in a garage or sheltered area for a few days before planting outside. Continue to keep the root ball moist.
Plant the tree as you normally would, mulch and water well.

Growing Tips

Plants require full sun, good air circulation and moist, well-drained, acidic soil.
Spruces are shallow-rooted and should always be planted high rather than low.
Mulch the root zone with a thick layer to keep plant roots cool and moist.
Consider available space and ultimate size of the chosen variety before planting.

Since we are interfering with the natural growth cycle of these trees, their survival through the season cannot be guaranteed. However, customers who have purchased living trees from us and followed the guidelines have reported 80-85 percent success rate with the trees thriving in the spring. It is fun to look out into your yard at trees from Christmases past!
