Putting on Airs: Tillandsias

Looking for something easy to grow? The air plant, Tillandsia, should be on the top of your list. Tillandsia is the largest genus in the Bromeliad family with over 550 species that vary in color, size, texture and shape. In its native habitat, it will attach itself to trees and rocks using its roots. The air plant derives the nutrients and water they need from the air, hence its common name. And guess what? No soil is necessary! This versatile houseplant is not fussy, and when given minimal care, will adapt to most home and office environments.

Light

Place your Tillandsia where it will receive plenty of light but not direct sunlight. Direct sun will dry out the leaves very quickly. Home or office fluorescent lighting works just fine.

Temperature

50 – 90 degrees Fahrenheit

Water

Once a month, soak your air plant in water for about 20 minutes. If the plant is flowering, a delicate rinse would be more appropriate so that the bloom is not damaged. When through soaking, shake off the excess water from the plant and place in an area with good air circulation. In between soaks, spritz it once a week with clean water from a spray bottle. Indoor heat and air conditioning rob moisture from the air. If the leaves of your air plant start to wrinkle or roll, this is a sign of dehydration. If this happens, give the plant a good soak and spritz it more than once a week.

General Maintenance

It is not unusual for the outer leaves of the air plant to dry out and turn brown, simply remove them. If leaf tips dry a bit and turns brown, cut the tip off and continue with regular care. The plant will grow and look just fine.

One final note, Tillandsias have beautiful brilliant blooms but only bloom once in their lifetime. Depending on the species, the bloom may last several days to several months.

Easy, right?

Biokovo Geranium

“So many Geraniums, so little time.” If this is your motto, we completely understand. There are so many fantastic varieties to choose from, but Geranium ‘Biokovo’ is extraordinary. Allow us to tell you why.

First, a little clarification regarding geraniums. Unlike our tender summer annual, commonly called “geranium” (genus: Pelargonium), true Geraniums are hardy, low growing, groundcover perennials commonly known as Cranesbill. I know, this is confusing, but when you see these two “geraniums”, they look nothing alike and they certainly do not behave similarly.

G. ‘Biokovo’, originally found growing in the mountains of Croatia, is cold hardy and semi-evergreen in hardiness zones 5 – 8. Growing up to a foot tall, this Cranesbill blooms in late spring, May to June, with five-petaled, ¾ inch, white flowers tinged pink. The leaves are slightly hairy, lobed, medium green turning orange-red in the fall and are highly aromatic with a pungent, orange-like scent when bruised.

Produced on spreading rhizomes, G. ‘Biokovo’ is easily grown in well-drained soil with average fertility. It is relatively drought tolerant once established and will thrive planted in either full sun or part shade. Fertilize in early spring. Plant divisions may be done in either spring or fall.

Use ‘Biokova’ in the front of the perennial border and in rock gardens. It will steal the show as a long blooming ground cover or edging plant. There are no serious pest or disease problems associate with this or any of the many other hardy Geraniums. It attracts butterflies and resists deer and rabbits.

No wonder Geranium x cantabrigiense ‘Biokovo’ was the 2015 choice for Perennial Plant of the Year!

Growing Under Black Walnut

If you have a black walnut tree on your property, you know how difficult it can be to find anything that will grow anywhere near this plant.

Black walnuts release a substance called juglone into the soil, which is toxic to many ornamental and edible plants and can stunt their growth significantly – in fact, juglone is used as a herbicide in some areas! A mature black walnut tree can have a toxic zone with up to an 80-foot radius, depending on the tree’s size and age. Every part of the walnut tree contains juglone and this substance remains in the soil long after the tree is cut down, continuing to inhibit anything that may be planted in its place.

Fortunately, there is a wide variety of plants that are less affected by juglone and can still thrive in contaminated soil. When choosing to plant in an area where a black walnut is located or where one once stood, it is safe to make your selection from the lists below.

Heath or Heather

Often mistaken for one another, heath (Erica) and heather (Calluna) look amazingly similar. To confuse things further, heath is frequently referred to as “spring heather” and some landscapers, garden centers and nurseries may use the names interchangeably. Both types of plants belong to the Ericaceae family, and they share many similarities.

Which is Which?

The key difference between these two popular landscaping plants is that heath blooms from winter to early spring while heather blooms from mid-summer to early fall. Heath features slim, needle-like foliage, while heather’s foliage is flatter and more scale-like. Heath generally only grows to 12 inches tall, while different heather cultivars can range from 8-20 inches tall. With their many similarities for location, soil type and sunlight, however, it is easy to grow these two shrubs together for a much longer and more brilliant flowering season.

Heath and Heather in the Landscape

Both heath and heather are low maintenance, low growing, perennial shrubs that love well-drained, acidic soil, but do not plant them too deeply or their shallow root systems may rot or smother. Heath, or spring heather, has tiny, urn shaped flowers in white, rose or fuchsia and is readily available in early spring. Heather will be more popular later in the season and into early summer, and its bell-like mauve, rose or lavender flowers provide lovely color to the landscape later in the season. Depending on the cultivar, heather’s foliage can range from bright green to golden yellow, reddish or even silvery-gray.

Both plants should be watered well, and mulching around the shrubs will help inhibit weeds and conserve moisture without overwatering. Pruning should be done just after blooming is finished to maintain and shape the plant mounds and discourage overgrowth and legginess.

Heath and heather look terrific planted en masse on a sunny hillside or in the shrub border with other acid-loving plants like azaleas and rhododendrons. They are a welcome addition to the rock garden and can brighten up a dwarf conifer grouping or container garden. Their mounding habit makes the plants easily spill over edges for a naturalized, graceful organic look ideal for cottage gardens and flowing landscape design.

It is important to note, however, that deer can be very attracted to both heath and heather. If these backyard visitors are a problem in your garden or pester your landscape, you may want to take a variety of steps to keep them away from your beautiful shrubs.

Planted together, heath and heather will provide you with a succession of dainty blooms to take you through the entire growing season.

Sweet Peas, the “Queen of Annuals”

For many of us, it’s the sweet pea that declares, “spring is here!” The colors and sweet fragrance announce the coming of warmer days like no other.

The hardest part of growing sweet peas is choosing from the riot of colors. From the palest of pastels to the most vivid of hues (including stripes), reds, pinks, white, blues, purples, yellows…the list seems endless. Many gardeners buy mixed packages of seeds to avoid the decision.

Look at your choices. Do some of the packets confuse you? Wondering about the difference between “tendril” and “non-tendril?” If the seed package says “tendril” this means the plants have small green growths to attach to a surface or netting to help the vine grow upright. This is how the taller sweet pea vines support themselves as they grow to 6′ (or more!). The varieties with no tendrils remain more compact, making them great in containers. Some of these will trail downward. Other dwarf non-vining varieties act as annual fillers in the mixed garden bed or as borders. What fun!

They’re super easy to grow…just sow the seeds 2″ deep in rich well-draining soil in a full to partial sun location. If the soil is heavy, add compost to improve the texture. Keep the soil moist. Germination should occur within 10-28 days. Continue even and consistent watering. When seedlings are 4-5″ tall, thin to create 5-6″ spacing between plants. To encourage bushy and compact plants, pinch the tips when three sets of leaves form. Generally, do not provide additional fertilizer, otherwise the plants may be lush but the flowers will be sparse.

Sweet Pea Secret! Improve the germination rate, especially of the darker colors, by using nail clippers to nick the seed coat and soak overnight before planting.

If you’re impatient, consider buying seedlings from your garden center. This way you’ll have fragrant sweet pea bouquets a month earlier. Here’s another secret, remove any flowers when transplanting. Yes, this is difficult, but it encourages stronger root growth to produce larger flowers later. You’ll be glad you did it.

Those long-lasting, colorful and fragrant flowers are so sweet in large loose arrangements. They’ll easily last a week if you change the water daily and snip off a bit of the stem. Remember, the best way to extend the sweet pea blooming season is by daily picking early in the day. Definitely, not too difficult.

Seeds for perennial sweet peas are also available. Unlike annual sweet peas, the perennial plant will continue to bloom throughout our warm, humid summers. Annual sweet peas tend to have a gloriously heady scent. This is a feature sorely lacking in the perennial form.

By the way…if you just can’t get enough of your annual sweet peas, grow them again in the autumn. Yes, you can! Why do most of us only grow sweet peas in the spring? Probably because we just don’t think about them in the fall. However, they grow just as well in the cool autumn as the spring. Just remember to provide enough time for flowering before the first frost hits.

Needled Evergreens for a Shady Space

Evergreens are a very important addition to the winter landscape. During the coldest months of the year, when most other plants have been stripped of their leaves or have died back to the ground, evergreens are the stronghold in the garden that provide stunning texture and color, shelter for winter wildlife and the hope of spring for everyone.

Choosing a broad-leafed evergreen for a shady location in the garden is simple. There are so very many to choose from: Rhododendron, azalea, camellia, aucuba and cherry laurel are just the beginning, and there are many more options for any size or shape of shady space. It’s a different story when it comes to hunting for a needled evergreen for that darker corner of the landscape, but it is not impossible.

Popular needled evergreen options for shady spaces include…

  • Canadian Hemlock (Tsuga canandensis) – Broadly conical and gracefully branched, reaching up to 75 feet high.
  • Dragon’s Eye Pine (Pinus densiflora ‘Oculus-draconis’) – Part shade. A very unique, asymmetrically shaped pine with a pale halo on the needles.
  • Dwarf Hinoki Cypress (Chamaecyparis obtuse ‘Nana Gracillis’) – Slowing growing, compact plant with dark green scale-like leaves.
  • Japanese Cedar (Cryptomeria japonica) – Light shade. Graceful, pyramidal tree with bluish-green scaly foliage and exfoliating cinnamon-colored bark. Growing to 65 feet tall.
  • Japanese Umbrella Pine (Sciadopitys verticillata) – Light Shade. Needles are thick and succulent, whorled around the branches.
  • Nootka False Cypress (Chamaecyparis nootkatensis) – Light to part shade. Narrowly pyramidal growing up to 60 feet tall.
  • Russian Cypress (Microbiota decussate) – Part shade to full shade. Low to the ground forming a rosette of soft, graceful branches. Great ground cover for a shady location.
  • Spreading English Yew (Taxas bacata repandans) – Part shade to full shade. Three feet high and mounding. Great foundation plant in front of windows or at the back of borders.
  • Upright Japanese Plum Yew (Cephalotaxus harringtonia ‘Fastigiata’) – Part to full shade. Four foot tall, stiff, linear form.
  • American White Cedar (Thuja occidentalis) – Light to part shade. Scale-like foliage formed into flat plane fans. Grows up to 40 feet tall.
  • False Arborvitae (Thujopsis dolabrata) – Light to part shade. Pale green leaf scales with white undersides. Grow up to 65 feet tall.

Not sure which of these evergreens may do well in your landscape? There are different cultivars to explore, and our experts can help you make the best choice for your landscaping needs.

Keeping Cats Out of the Garden

Do you love cats but don’t love them in your garden? Outdoor cats will seek out a nice patch of soil to do their business or to roll around and play. Cats will mark their territories on sheds, fences or plants, and may even raise a new litter under a deck or in an open shed. Fortunately, there are a number of safe yet effective ways to keep our furry friends, or those of our neighbors, from messing up the garden.

Discouraging Cats

Whether the cats visiting your garden are prowling pets, lost strays or wild-bred feral cats, the same techniques can be used to make your garden and landscape less cat-friendly. Popular options include…

  • Commercial Repellents
    There are a many effective odor and taste repellents on the market. Seek out a product that is safe for humans and animals made from botanical oils. You will need to reapply this type of repellent after a heavy rain but usage will decrease once the cat is retrained to go elsewhere.
  • Citrus Smells
    Cats don’t like the sharp, tangy smell of citrus. Instead of composting them, throw the peels of oranges, lemons, limes and grapefruit on the ground where cats tend to visit.
  • Heavily Scented Plants
    Some plants are known to repel cats by their scent, particularly plants with strong odors that will irritate sensitive feline noses. Try planting Coleus canina, otherwise known as scaredy cat plant, along with pennyroyal, rue, lemon-thyme, geranium or lavender throughout the yard and garden.
  • Uncomfortable Ground
    Use stones instead of mulch as a ground cover to prevent cats from digging. Sharper, larger stones are best and will be uncomfortable for cats to walk across or lay on as well. You can also lay chicken wire on top of the mulch to make it less comfortable for cats and to prevent digging.
  • Opt for Thorns
    Plant low growing, thorny plants such as carpet roses, barberry or prickly pear at the base of your bird feeder to protect your feathered friends from predatory cats. Use thorny plants in borders or alongside fences to help keep cats away as well. Even plants with sharp, stiff foliage, such as holly, can be effective.
  • Sprinklers
    Install a motion-activated sprinkler. This method is used to frighten cats away, not to soak them. As the cat is retrained to go elsewhere its use eventually becomes unnecessary.
  • Sound Deterrents
    Install an ultrasound device containing a motion sensor which, when triggered, gives off a high-pitched sound that is imperceptible to humans but bothersome to cats. With their sensitive ears, cats may avoid any area where the sound is strongest.
  • Remove Food
    Be sure there are no food sources for outdoor cats in your yard. Do not feed your own pets outside, and keep trash cans tightly covered or inside a garage where cats cannot reach them. Keep compost piles behind a fence and under a mesh cover as well so cats cannot forage for scraps.

Using several techniques simultaneously will have the best effect at discouraging cats. These are clever, intelligent creatures that can easily overcome one obstacle, but when you have used several tactics at once, the cats will take the easier route of simply staying away.

What You Should Never Do

While there are many ways to keep cats out of your yard, you should never take steps that could deliberately injure or kill the animals. Avoid harmful traps, toxic poisons or setting your dogs on outdoor cats, as these methods can easily backfire and hurt local wildlife instead. With patience and perseverance, it is possible to keep cats out of your garden safely.

Holey Moley, Shrew or Vole!

Mole, vole or shrew: ever wonder what the difference is between these pests, or why you should care? All three of these mouse-like creatures may be seen in or around your garden. Identification is important in determining if and how you should control these critters.

Moles

  • Identification: A mature mole will grow 5-7 inches from snout to tail. Moles have soft, thick, velvety-gray fur, a long, blunt snout and an approximately 1-inch long tail. Their eyes and ears are inconspicuous, hidden under their fur. Their paddle-like front paws are two to three times wider then their rear paws.
  • Damage: Moles, in search of grubs, beetles and earthworms, burrow in the ground and create tunneling in the lawn and garden. They surface occasionally leaving small hills of loose soil. Moles are solitary, subterranean creatures.
  • Control: Reduce food supply by controlling grubs in the lawn. Use repellents containing castor oil, or toxic baits placed in the tunnel but out of reach of pets. There are several different styles of mole traps available on the market.

Voles

  • Identification: Voles, often called meadow mice, are a little larger than moles reaching 5-8 inches long at maturity. Their heads are rounded, their eyes are larger than shrews, their fur is brown, short and smooth, their front paws are about the same width as their rear paws and their tails are about 1 ¾ inches long.
  • Damage: Voles are herbivores that feed on bulbs, tubers and tender young plants. During the winter, often under the cover of snow, voles will eat surface roots and chew bark from the base of trees and shrubs often causing the plant to girdle and die. Voles, unlike moles and shrews, are social and where you find one, you will find many. Voles will often tunnel in mulch or ground cover above ground leaving surface trails. They sometimes run through old mole tunnels eating plant roots.
  • Control: Use Thiram-based repellents. Set up mouse traps baited with peanut butter or apple slices. Keep mulch away from tree trunks. Remove snow from the base of trees and shrubs in the winter. Protect young trees by wrapping the lower trunk in wire mesh. Apply predator urine to the area and reapply frequently. Do not use poisons.

Shrews

  • Identification: A mature shrew will reach 4-5 inches long. Shrews have a thin tail about 7/8 of an inch long, soft, grey, short fur, small beady eyes, small ears and a pointed snout.
  • Damage: Shrews, like moles, are insectivores. They eat earthworms, grubs and other insects. Shrews, however, are often seen above ground although they tend to use old mole and vole tunnels to get around. Shrews cause no real damage to plants and eat a variety of insects making them beneficial in the landscape and garden.
  • Control: None necessary.

Growing Veggies in Containers

Do you dream of a delicious, homegrown harvest but don’t have the land to use? No longer should a shortage of garden space prevent you from growing your own fresh vegetables. As long as you have a sunny location you can have your own mini-farm on your porch, patio, deck, balcony, roof-top or doorstep!

Why Use Containers?

The benefits of growing containerized vegetables go beyond the issue of space. There are plenty of other compelling reasons to plant your veggies in pots, including…

  1. Vegetables are amazingly ornamental and can be just as decorative as any other container plants or flowers.
  2. There are fewer problems with pests such as groundhogs, deer and rabbits and soil borne diseases.
  3. The soil in pots warms up more quickly in the spring allowing for earlier planting and an extended growing season.
  4. Less bending, squatting and kneeling is required for gardeners with limited mobility.

Vegetables can be grown in any vessel that can hold soil, has adequate drainage and is large enough to hold a plant. There are endless options available on the market or you may recycle items that you already have as long as they meet these requirements. Use your imagination – try a wheelbarrow, wine barrel or just a plastic bin, and you’re ready to plant!

Best Vegetables for Containers

While all veggies can be grown in containers, some are better suited than others. Plants that grow particularly large, that sprawl or that must be grown in large numbers to ensure an adequate yield may take more effort and careful site planning with an adequate container. Similarly, vining plants need not be avoided. Trellis these plants up against a wall or fence or allow them to cascade down from a taller pot or a container placed up high like on a stone wall. For smaller selections, a hanging basket or window box may be used. Many sprawling and vining vegetables are now available by seed in dwarf, compact or bush varieties. These are bred specifically for small spaces and containers and are worth seeking out.

Tips for Container Vegetable Gardens

Growing vegetables in containers does take some unique thought and isn’t quite the same as planting in a traditional garden. When planning your delicious container garden, consider…

  • Containers: Size matters when planting in containers. The bigger the container, the more soil it can hold. More soil more and more moisture means less watering. Take note that porous containers like terra cotta dry out more quickly and will therefore require more frequent watering.
  • Soil: When planting, choose a good quality potting mix. Soil from the ground may contain insects or disease or may be too heavy. Add an all-purpose balanced fertilizer at time of planting. It is also good idea to mix water absorbing polymers into the soil. These granules can hold up to 400 times their weight in water and help reduce watering from 30-50 percent.
  • Plants: Some of the vegetables that you select may be directly seeded into your container; these would include peas, beans, radishes and corn. With most vegetables you may wish to transplant seedlings into your container, either home-grown or garden center purchased. You will generally find a wider selection of vegetable varieties and unique options available in seed as opposed to purchased seedlings, if you want to use your containers experimentally.
  • Supports: Supports should be placed at time of planting for large or vining plants. This will ensure the young plants are not disturbed or damaged with supports added at a later time. If the supports are outside the container, however, they can be added only when they are needed.
  • Location: Your vegetables will require at least 6 hours of direct sun a day. If this is not possible you may try placing your pots on dollies or carts and moving them to a sunnier location as the sun moves throughout the day. Note that good air circulation is important for disease control.
  • Watering: Test soil frequently for water to make sure that you keep it evenly moist. Water the soil, not the plants, to avoid the spread of disease. Check soil moisture more frequently during the summer months when evaporation is faster. Mulching your containers with salt hay or grass clippings will help keep soil cool during the summer months and reduce the frequency of watering. If possible, a drip system can be a great option for keeping containers watered.
  • Fertilization: Fertilizer leaches through pots quickly. Fertilize containerized vegetables at least once a week with a water soluble fertilizer. Always be careful to follow the directions on the fertilizer package and follow the recommended rate. Too much fertilizer may burn or kill your plants, but too little will result in undernourished, underperforming plants.

With appropriate care that caters to the needs of containers, your small-scale vegetable garden can be just as lush and productive as any larger, more intensive space, and you’ll soon have a bountiful harvest to enjoy.
