Have your houseplants been looking dingy and dry no matter how much you may water them? Have they lost the lustrous glow their foliage first had when you got them? Poor humidity may be the cause. Many of our houseplants hail from the tropics and grow in humidity of 50-80 percent, considerably more humid than typical homes. The trick is to know your plant’s preferences and be able satisfy it. Putting a cactus in the shower will cause it to rot, while a fern is perfectly happy.

But what can you do if you really want that fern in the family room where the humidity may only be 20 percent in the winter? If your plant has brown leaf tips or margins it probably needs more humidity and is asking you to increase it. Luckily, it’s easier to add humidity than it is to take it away.

Easy Ways to Increase Humidity

There are several ways you can easily increase the humidity around your houseplants. If they only need the air a little more humid, just one technique may be sufficient, but if they are humidity-loving plants, you may want to try several options at once to really give them a humidity boost.

• Pebble Tray
  Place an inch of small pebbles, marbles, shells or gravel in a 2″ deep tray, half fill the tray with water and set your plant on the pebbles. Don’t set the pot in the water, as the wicking action will saturate the pot soil and could lead to rotting roots and overwatering. As the water in the tray evaporates, it increases the humidity immediately around the plant. When you water the plant, pour out the water from the tray to prevent mineral buildup, algae and insect growth.
• Plant Grouping
  Rather than spacing plants throughout the room, group them together to take advantage of the moisture each plant produces through transpiration. Grouping plants can increase humidity by as much as 15 percent. Place the entire group on a pebble tray if additional humidity is required. Allow air circulation between the plants by ensuring the plants are not touching each other, and rotate individual plants periodically to encourage straight growth and distribute humidity absorption.
• Misting
  Use a misting bottle daily to increase humidity and cleanse leaf pores, which tend to clog with dust. However, to prevent leaf rot, do not mist plants with “velvety” leaves such as African violets. Do not over-mist plants to the point where their leaves are dripping wet, or else they may suffer from overwatering.
• Humidifiers
  Available in a variety of sizes, humidifiers increase the humidity in a larger space. You may also find yourself breathing better when using a humidifier. Our houses become very dry in the winter because of furnaces, heat pumps and fireplaces, and humidifiers can not only help houseplants, but can also help alleviate dry skin, limp hair, chapped lips and hacking coughs.
• Terrariums
  If your house is just too dry for the plants you would like to grow, try planting them in a terrarium. These nearly enclosed vessels create miniature environments perfect for humidity-loving tropical plants such as ferns, orchids and mosses. You will still need to water your terrarium, but because much of the moisture is trapped, the humidity in the enclosure is much higher.

Are you trying to add drama and beauty to your shady spots but keep finding only bland, lackluster plants? You won’t want to overlook Brunnera macrophylla ‘Jack Frost’ with its stunning appearance and easy care.

Introducing Brunnera macrophylla

Also called Brunnera-Heartleaf and Siberian bugloss, this plant is a stunner for its delicate foliage. The broad, heart-shaped leaves of ‘Jack Frost’ are dark green with a heavily frosted metallic silver overlay. This allows only the green veining to peep through, giving the plant a crackle-like finish with a thin green border. Sprays of tiny bright blue forget-me-not like flowers burst forth in mid- to late spring, growing well above the foliage on delicate stems.

Using Jack Frost in the Landscape

Excellent in a woodland garden, the genus Brunnera is a group of classic perennials valued as a shade tolerant ground cover. The variegated forms are slower to spread than most other species, making this cultivar ideal for smaller spaces where crowding may be a concern, such as around younger trees, in smaller beds or in borders along a shady fence, deck or pathway. This plant is fabulous as a specimen plant or may be massed to show off its phenomenal floral display. ‘Jack Frost’ would also make a wonderful addition to a shady container garden on a deep porch or covered deck. The flowers are long lasting when cut and can be lovely, delicate additions to arrangements. Because this plant is resistant to deer and rabbits, it can also be a favorite in wildlife-friendly areas.

Proper Care is Key

Brunnera is a woodland plant, and that must be kept in mind if it will be able to show off its full potential in your landscape. ‘Jack Frost’ should be grown in full shade and consistently moist soil in southern regions to mimic the thicket-like conditions it naturally favors. In the north, morning sun is acceptable as long as the soil remains moist and the temperatures in the sun do not rise too high. Although tolerant of many soil types, this plant will grow best rich soil. If needed, amend soil with lush compost to improve its condition and provide proper nourishment. Little care is needed once Brunnera is established. Cut back the old foliage in the spring rather than in the fall; it will help to protect the crown during the winter. A winter mulch is also recommended to help keep the soil moist and warmer to protect the roots.

Brunnera macrophylla ‘Jack Frost’ may not be widely known, but once you meet it, you’ll want to invite it to every shady part of your landscape!
