Caution in the Garden… Chlorosis

Yellow means caution, even for plants. While leaf yellowing, known as chlorosis, may be a signal that there is a problem that requires attention, it may also be normal. Understanding when this coloration is to be expected and when it indicates a problem is essential to be sure you’re giving your plants the proper care.

The Good and the Bad About Chlorosis

Chlorosis is the scientific word used to indicate the full or partial yellowing of plant leaves or stems and simply means that chlorophyll is breaking down. There are times when this is normal, expected coloration, and there are times when it indicates deeper problems that need attention.

  • Normal Chlorosis – Yellowing leaves at the base of an otherwise healthy plant is normal; the plant is simply utilizing the nitrogen and magnesium for exposed leaves near its top rather than older, lower leaves. These yellowed, older leaves will eventually shrivel and fall off as newer growth emerges at the top of the plant.
  • Chlorotic Response to Light – Moving a plant from full sun to shade, or visa-versa, can cause yellowing leaves as the plant reacts to the change and stress. Make sure that you grow and maintain your plant in the proper light. Also bear in mind seasonal changes that may affect how much light a plant is exposed to, even if it hasn’t been moved.
  • Chlorotic Response to Moisture – Sudden changes in soil moisture may damage or kill plant roots which can lead to yellowed leaves as the roots are unable to take up sufficient moisture. Most otherwise healthy plants, however, are able to grow new roots as they readjust. Maintain correct soil moisture or move the plants to a more favorable environment.
  • Mineral Deficiency – A shortage of some key mineral nutrients will cause chlorosis in plants. Often, a yellow leaf indicates a lack of nitrogen, however, magnesium, iron, sulfur or manganese deficiencies are indicated by yellowing leaves with prominent green veins. A magnesium deficiency will manifest itself in the yellowing of older leaves. On the other hand, an iron deficiency presents itself in the yellowing of new or young leaves. A simple soil analysis will let you know what minerals or trace elements your soil is deficient in.
  • Soil Factors – Although essential and trace elements may be present in the soil, many other factors affect how the plant uses and absorbs them. If the soil pH is too high/low or there is too much salt in the soil, the plant will not be able to utilize the available nutrients. Test your soil pH and adjust as necessary to be sure the plant can absorb nutrients appropriately to maintain proper foliage colors.
  • Toxins – Although this doesn’t happen frequently, pollutants like paint, oil, chemical solvents, airborne herbicides or pesticides or other pollutants may cause leaves to turn yellow and dark brown before dying. In this case, remove and dispose of the plant and its surrounding soil, and mark the area to be sure it can be treated appropriately and no other plants are inadvertently exposed to the toxins.

It can be alarming to see healthy plants suddenly yellowing, but by understanding chlorosis and how it happens, you can take steps to determine the cause of the color change and what to do to help your plants recover.

Making a Terrarium

Hold onto your gardening hats, folks! Remember terrariums? A new trend revitalizing this old style is now better than ever. Creating a theme for your terrarium is easier too, with the all the miniatures now available. Remember those skinny-necked bottles and what a hassle they were? New container styles make terrariums easier to plant, simple to maintain and more beautiful in your home.

Style

What is your terrarium’s style? Tropical with ferns, arid with cacti or beach-like with tiny grasses, sand and water-like pebbles? Will you have figures such as fairies or gnomes? To choose the plants, consider the lighting where you plan to place the terrarium. If your gnome home is to be in the corner, consider using a cute fluorescent light or similar illumination to help keep your terrarium’s plants healthy and thriving.

Container Shape and Size

Choose your container and ensure it has enough room for your completed dream. Clear glass allows views of different layers of sand, soil and top dressing, giving your terrarium extra depth. Container shapes include hanging, footed, cylindrical, spherical, even leaning. Multi-sided geometric shapes are popular, as are smooth, curved shapes with a natural flow. If your garden includes tropical plants, consider a container with a smaller opening or a lid to increase humidity for healthier plants.

Don’t forget to consider size – tiny terrariums with just a plant or two are popular and can be hung like ornaments or make great gifts, while larger containers can create an entire microcosm and unique environment for a stunning display.

How to Plant

Planting a terrarium takes a little extra care, but is no more difficult than planting any houseplant.

  1. Put an inch or two of small gravel, pebbles or expanded clay pellets into the container, providing a drainage base. Mixing in several tablespoons of horticultural charcoal prevents odors. If the container is large enough, layer other colors or sizes of pebbles or sands to create visual interest when viewed from the side.
  2. Soil goes in next. Many plants grow well in light soils mixed with peat moss and vermiculite or perlite. Moistened coir is another option. Alternatively, consider special prepared soil mixes for African violets, succulents or cacti.
  3. Create a landscape plan by first arranging the plants on the tabletop to determine where they will be placed in the container, taking into account how the plants may touch the sides or top of the container.
  4. Plant the largest plant first. Dig a small hole, place the plant, and firmly tamp the soil around it. This is very important to stabilize the plants and remove air pockets. If the space is tight, smaller plants may be able to help stabilize larger plants.
  5. After placing the plants, you may want to top-dress with decorative pebbles or bark. Sand looks great around cacti. This is also the time to place fairies, cottages, twigs, larger stones, marbles and other decorative items in your terrarium to create the desired theme.
  6. When everything looks good (look at it from all sides and angles), use a small artist brush to clean any loose dirt or sand away from the sides and leaves.
  7. Use a mister to water the plants. Because the container acts as a small biosphere and much of the moisture is recycled, a little water lasts for quite awhile. Do not overwater your terrarium or the plants may rot, and replacing them can be a challenge.

Place your terrarium in its new location and enjoy its beauty and your accomplishment!

Tools for Holiday Gift Giving

It’s easy to shop for gifts for the gardeners on our holiday list. There are always new tools available for the serious, and not so serious, gardeners in our lives. In fact, there may be too many to pick from, but we can help you narrow down the selection to find the perfect gift.

  • Pruners
    Every gardener faces the need to prune or deadhead flowers at some time. From hand pruning a wayward twig to removing a branch 10′ overhead, there is a pruning tool to make any job easier.Because everyone’s hands and hand strengths are different (and some folks are left-handed), hand pruners are the most personal of garden tools. Two well-known companies, Corona and Felco, produce hand pruners and saws. Hand pruners come in two basic styles: by-pass pruners have two sharp blades that pass each other when cutting, while anvil pruners have one sharp blade cutting the material against the other flat blade. Both companies offer several models of these styles to accommodate different pruning needs, sizes of hands, hand strengths and orientations. New ergonomic models optimize hand strength and minimize discomfort.Another option is a pruning saw, which is different from any old saw. A larger sheath model saw makes short work of removing a large branch. A smaller fold-up model is great to have in a gardener’s pocket while making the daily rounds. Different models, with different lengths and teeth sizes, ease sawing effort. Check out our gift shop to see all the options.

    When an overhead branch requires removal, a gardener appreciates a pole pruner. Not only is it a hassle to get out the ladder, it’s dangerous to perform the sawing and pruning motions when balancing. The redesigned Fiskars pole pruners are powerful, with a telescoping pole to 12′ extension. If the branch is too large for the pruner, the detachable saw blade cuts through it. Unlike the old style pole pruners, there are no ropes to pull (and tangle in the tree!). Pruning heads even swivel to get a closer and cleaner cut. The Fiskars pole pruner, or Pruning Stik®, won’t fit in your gardener’s stocking, but it’s certain to be a winner!

  • Shovels and Spades
    Shovels and spades are other key gardening tools. While many shovel versions exist, the round point shovel is the most common. The heavy-duty blade point pushes through the soil and the rounded blade scoops the soil. Square-edged shovels also scoop soil and other materials in addition to digging but don’t have the point. Spades, basically a smaller version of a shovel, are usually flatter. Most shovels have a rolled lip, or rim, on the top of the blade. This is where the user puts their foot to push the tool into the soil. The larger the rim, the more comfortable for the foot when doing a lot of digging.Better quality shovels and spades are powder coated to prevent rust, are pre-sharpened, and the blade is welded or forged to the shaft. Shafts vary in style and material. Wood, plastic or fiberglass shafts may be straight or end with a handle. A fiberglass shaft lasts longer than wooden shafts and doesn’t require annual maintenance and cleaning. Ergonomic designs reduce the chance of wrist injury. Other shovel/spade specialties include the trenching shovels to dig deeper than the standard 12 inches, border spades and smaller sized round point shovels to dig smaller holes or working around existing landscape. And don’t forget trowels and other hand digging tools. If your gardener has a special digging or scooping need, there’s a shovel or spade for it.
  • Hoes
    Hoes may seem old-fashioned, but there are new designs every gardener can appreciate. Used since ancient times, the hoe performs many functions in the garden depending upon its configuration. The regular hoe’s rectangular shaped blade, positioned at a right angle to the shaft, weeds and shallowly cultivates. The V-shaped version, also called the Warren hoe, has a point to dig furrows for seed planting. The other side closes the furrows after planting. The “weeding” and “action” style hoes make short work of removing weeds.
  • Rakes
    A rake is another essential tool. Think of a leaf rake as a large hand – it allows the user to gather a large amount of material such as leaves and debris. Rakes may be metal or plastic, quite large to cover a large area quickly or quite small to get under plants without damage. Rakes are practical and save time and energy. Specialized rakes include the two styles of garden rakes, flat and bow, and thatch rakes to remove thatch from lawns to keep turf lush and thick.

There’s just one problem with giving these larger tools as gifts – they’re very difficult to wrap!

Herbal Delights

No matter how cold the temperatures or how deep the snow, you can enjoy the pleasures of herbs this winter season by growing them in your windowsill. Herbs are great for adding zest to any food and are a delicious substitute for salt and artificial flavors. They can also make dinner a visual delight! Add herbs to breads, soups and stews for flavor or use as a lovely garnish. Here are some great selections to try…

Rosemary is a must for the cook. Fresh rosemary is much richer and more fragrant than dried sprigs. Its needle-like foliage has a piney or resinous aroma and flavor. Rosemary is good with any meat or poultry, with stronger tasting fish, and with pizza, breads and potatoes. It is companionable with garlic and citrus flavors. A pleasing apple jelly can be scented with rosemary for a gourmet touch.

Chives, being a member of the onion family, is one of the few flavoring plants that appreciates some fertilizer. The hollow spears should be cut as needed by clipping a few spears just above the ground. It is used mostly as a garnish or final ingredient wherever a light onion taste is wanted, and it won’t overpower your recipes.

Mints are a necessity for herb windowsill gardens. No one would want to be without spearmint and peppermint, and maybe orange mint, for fresh teas and additions to fruit cups and ice cream. Fragrant and luscious, mints also make delightful garnishes for drinks or can be frozen into ice cubes.

Sage is a standby for poultry, breads and stuffings and combines well with corn or apples. Fried leaves are good to nibble. Experiment with different types of sage to enjoy their subtle variations and different flavors.

Thyme, a huge family of small upright, mounding or creeping plants, comes in a variety of flavors. You will find varieties labeled French, English, Common and Lemon, with leaves that may be all green or silver-edged or even variegated with gold. Every herb garden should have some thyme, and it pairs will with lamb as well as in marinades and salads.

Oregano is the hardier cousin of marjoram. It is a familiar flavoring in Italian and Greek cooking, in meats, sauces and of course in pizza. Oregano can be added to salads, used in marinades or mixed in with breads for rich flavor without any butter needed.

When growing your herbs, be mindful of their sunlight needs and keep them away from heating vents that can dry the soil out too quickly. Use organic fertilizers like fish emulsion and seaweed sparingly. Although fertilizers make the plants beautiful to look at, the less fertilizer used on an herb, the better it will taste. Now is a great time to start growing or to add to your culinary herb collection. Winter is the perfect time to start adding zest and flavor to your cooking!

Season of the Ficus

Houseplants transform a house into a home, purify the air, promote relaxation and improve concentration. The ficus group includes four popular small trees grown as houseplants, each looking very different from one another, and each incorporating these and other great benefits. Wonderful as gifts, smaller plants continue growing and reminding the recipient of the giver’s good wishes for many years. A larger specimen can anchor a room or office, fill an awkward space and set a sophisticated decorating tone. We sell both small and large sizes of these easy-to-grow plants.

Ficus Types

There are several types of ficus to choose from. Whether you are giving the plant as a gift or want to enhance your own home with more greenery, consider these different varieties to choose the ficus option that best suits your needs.

  • Weeping Fig (Ficus benjimina): Your classic ficus variety, the weeping fig has green or variegated foliage with 2-4″ long, twisted and pointed leaves on twiggy, spindly branches. The tree has a graceful rounded and weeping appearance. Can reach 5-6′ tall, making it ideal for smaller spaces such as apartments or condominiums.
  • Rubbertree (Ficus elastica decora): Emerging from bright red sheaths, the large, thick, oval variegated or green leaves of the rubbertree grow 10-12″ long and 6″ wide with a central rib of white on top and red on the underside. These can reach the ceiling in time, and this plant is often considered foolproof for its easy care. Because of the space needs, these plants are best for larger areas with abundant room.
  • Fiddle Leaf Fig (Ficus F. lyrata): Similar in size to the rubbertree with a strong structural form, this fig’s leaves mimic the elegant, curving shape of a violin. The large leathery and textured leaves reach 12-18″ in length. This is another variety that will do best with more space so its form is well appreciated.
  • Indian Laurel (Ficus retusa nitida): Growing to a 6′ tall weeper, dark green oval 2-4″ long leaves cover the drooping branches of this elegant small tree. New leaves provide light pink and bright green color contrasts to the older leaves. This is an ideal specimen for smaller spaces or anywhere a burst of natural color is appreciated.

All of these ficus varieties are among the easiest to grow houseplants, whether you want to nurture them from smaller, younger plants or are interested in larger, more mature specimens. Stop on by and pick some wonderful ficus plants up for gifts or for yourself.

Getting Your Trees and Shrubs Ready For Winter

Winter wind and sun are responsible for much of the injuries your landscaping plants will sustain over the winter. The elements are especially hard on broadleaf evergreens such as rhododendrons, hollies, mountain laurel and boxwood. Being evergreen, these plants are constantly losing moisture through their leaves, but since the ground is frozen, the water in the soil is unavailable and they cannot replenish their supply. Drying winter winds and bright, reflecting sun only serve to compound the problem. Fortunately, there are a number of ways to prevent this.

  1. Make certain that the plants have plenty of water before the ground freezes as a plant in a water deficit situation is much more prone to winter injury. Keep watering plants until the first freeze, but water slowly so the ground is not saturated which would lead to ice heave and root damage.
  2. A heavy mulch of shredded bark or leaves, pine needles or straw can be spread around the plant to a depth of 3-5 inches. This will help preserve moisture in the soil and keep the soil warmer so delicate roots are not as easily damaged by ice and frost.
  3. To reduce the effects of the winds, wrap shrubs with burlap or other breathable fabric. This not only breaks the force of the wind, but also shades the plants from sun. Do not, however, wrap plants in plastic or tarps that would restrict air flow completely, or the plants may smother. Another option is to use Wilt-Pruf. It is sprayed on the plant to reduce the loss of moisture caused by wind and sun.
  4. Remember, younger plants, saplings and newly planted shrubs are more subject to winter damage so take special care of these. Plant as early as possible so they have more time to get established before winter sets in, and keep a close eye on them to minimize any storm damage through the season.
  5. After a heavy storm, inspect your trees and shrubs for damage. If boughs or branches have broken, prune them away immediately so they do not continue to tear and cause more injury to the plant. Use a soft broom to brush off a heavy accumulation of snow if needed, but do not try to melt away any accumulated ice or frost, as the temperature change can damage the plants.

With good preparation and conscientious care, your trees and shrubs can withstand even the cruelest of winter cold and storms, and they’ll be bursting into new spring growth before you know it.

Outdoor Ornamentation

Do you miss the vibrancy of your flowerbeds and the rich, lush colors of your landscape once winter sets in? With warm weather pots, window boxes and hanging baskets already in place, decorating the outside of your house this winter will be a cinch!

  1. Use only containers that are winter safe. Porous pots, like terra cotta, are not a good choice as they tend to crack when they freeze. Better choices include cast iron or aluminum urns, fiberglass or foam containers and cocoa-lined wire hanging baskets and troughs. For a truly holiday look, consider containers that may have red-and-green coloration or other holiday hues, or look for whimsical holiday-themed designs.
  2. Use the soil that is already in your containers. Remove just the tops from your previous plantings, allowing their roots to remain in the soil as an anchor for your winter arrangement. OASIS Floral foam is another good choice that works well for smaller outdoor arrangements like those in hanging baskets. You may also need some plant or gardening pins to help keep your arrangement in place and secure.
  3. Begin by adding greens to your container (note: your greens will last longer if soaked in Wilt-Pruf for 24 hours before using). Cut branches to the desired length and remove all green needles from the portion that will be inserted into the soil. Create a dense base for your arrangement using either white pine or spruce. Consider allowing some boughs to trail over the edge of the arrangement for more visual interest, or mix up different types of greens for interesting texture.
  4. Create a focal point for your arrangement with the addition of a few tall branches of curly willow, Harry Lauder’s Walking Stick, red twig dogwood or white painted birch. Position these taller elements near the back of the arrangement to allow more room for additional plants and decorative items. To add more magic to the arrangement, consider painting taller branches gold or silver.
  5. To include additional color and texture, incorporate more winter-themed plants into the arrangement. Magnolia leaves, holly, incense cedar, winterberry, China berry, pepper berry, protea, eucalyptus or other decorative branches and berries are all top choices. Go for a lush, tiered look for the best effect.
  6. To bring your arrangement to life add mini white or colored lights, desired ornaments and weather-proof ribbon. For a more whimsical look, consider garlands, candy canes, cranberry strings or even a fairy gingerbread house. Remove these when the holiday season ends and leave the arrangement intact until time for spring planting.
  7. You might spruce up around the pot to bring even more notice to your arrangement. Consider a ribbon around the pot, or add light-up gift boxes or wrapped boxes around the pot to create a larger focus.

With just a few steps, the outdoor containers you enjoy in spring, summer and fall can continue to be lovely accents for holiday and winter decoration.

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.
