Green Gardening

Planting a vegetable or flower garden seems like the perfect thing to do when you are looking for ways to adopt a greener, more environmentally-friendly lifestyle. Some traditional gardening practices, however, may not be quite as “green” as you might think. Planning your gardens with the environment in mind and choosing some practices that maintain healthy ecosystems can help you create a truly “green” garden. 

Tips for a Green Garden 

There are easy, effective steps you can take in your garden to go green, including… 

  • Plant local and native species of trees and shrubs which are naturally adapted to the conditions in your area, thus requiring less watering and having natural defenses for local insect pests and plant diseases.
  • Collect rainwater for watering your container gardens and new transplants, and adjust your irrigation schedule to compensate for whenever Mother Nature does the watering for you.
  • Use organic compost and mulch to improve soil health and reduce the need for pesticides and fertilizers. Better yet, make your own compost so you can adjust it to exactly what your plants need while keeping more waste out of landfills.
  • Opt for disease-resistant and pest-resistant plants rather than trying to force plants into an unfriendly area where they will need chemical assistance and extra maintenance to thrive.
  • Try to use natural products instead of chemical fertilizers and pesticides. Use traps, parasites and natural predators such as ladybugs and lacewings. Plants that repel insects – basil, chives, mint, marigolds or mums – mixed in with other plants can help keep pests away.
  • Choose wildlife-friendly plants such as flowerbeds that will attract hummingbirds, butterflies, bees and other pollinators, and don’t be upset to share some of your garden space with other critters.

These are just a few of the simple changes you can make in your gardening practices that will benefit the environment.

Green Products 

More and more “green” products are readily available to help you maintain the natural health of your garden. Before using a product, however, be sure it is suitable for your situation, and follow all application and use instructions. Even organic or eco-friendly products can become toxic contaminants if they are improperly used.

Popular options for green gardening products include… 

  • Dr. Earth contains probiotic beneficial soil microbes, plus ecto- and endo- mycorrhizae which feed the fiber of the living soil by releasing natural organic matter. People and pet safe.
  • Dr. Earth pest controls are organic controls for all of your pest problems, including all types of unwanted or troublesome insects. People and pet safe.
  • Espoma Organic Traditions line of products includes bone meal, kelp meal, garden sulphur, potash and garden lime for helping to improve your soil without artificial chemical compounds.
  • Bonide offers organic fertilizers as well as organic formulas for pest and plant disease control, such as fruit tree sprays.
  • Scotts Organic Choice lawn care products provide more environmentally friendly choices for your yard.

Developing “green” gardening practices benefits you and your family, your garden, your native plants and animals, your water supply – our world, all of us.

Growing Grass in the Shade

Cool season turf grasses prefer to grow in the sun. To establish a thick, healthy lawn of Kentucky bluegrass and perennial rye, you will need at least six hours of full sun daily. Fine and tall fescues are more shade-tolerant and require a minimum of four hours of full or eight hours of filtered sun a day. When plants do not receive enough sun, they cannot manufacture food (photosynthesis) effectively to support growth. As a result, plants that do not receive adequate sun are less heat- and cold-tolerant and more susceptible to disease and insect damage. When it is a tree or shrub that is causing the shade, there is also competition for soil nutrients and water. 

What does this mean for those of us with less than optimal light on our lawns? If it is grass that you wish to grow, it is not impossible, but you will have to settle for thinner turf. It doesn’t have to be any less healthy or hardy, however. Your chances of maintaining a healthy, thin lawn in a shady area is increased when adopting the following guidelines: 

  • Increase the amount of light and air circulation, if possible, by thinning tree canopies or removing the trees altogether.
  • Test your soil pH. It should read between 6.0-6.5 for growing fine fescue grasses.
  • If drainage is poor, improve it. Most turf grasses prefer well-drained soil.
  • Use a shady grass seed mixture with a high percentage of fine fescue grasses.
  • Do not sod. Most sod on the market is Kentucky bluegrass, which requires full sun.
  • Sow seed in late August to avoid heat and drought stress, weed competition and suffocation from falling leaves. Early spring is the second best time to seed.
  • During periods of drought, provide deep soakings to encourage a deep root system. Water early in the day to allow leaf blades a chance to dry and therefore reducing the possibility of disease.
  • Mow grass high, 3-4 inches. More leaf surface is required to increase photosynthesis in the shade.
  • Limit foot traffic in shady areas. This grass is already growing under stressful conditions and high use will contribute to its decline.
  • Fescue requires less nitrogen than other grasses. You may allow the grass clippings to stay in place. As they break down they will provide nitrogen to the soil. A spring and fall application of a high phosphorus fertilizer should also be used.

It is highly unlikely that you will have success when attempting to grow lawn in deep or heavy shade. The one exception is Poa trivialis, commonly known as rough bluegrass. This type of lawn is very shade-tolerant, but must have consistently moist soil. Without both heavy shade and constant moisture, you will not be able to grow a rough bluegrass lawn. 

Turf Alternatives 

Alternatives to turf in a shady area include: 

  • Shade-Tolerant Evergreen Ground Covers

Though not quite the same as grass, these groundcovers provide a green landscape without needing plentiful sunlight. They can also be lower maintenance and don’t require mowing. Selections include common periwinkle, pachysandra, purple wintercreeper, English ivy and lilyturf.

  • Perennial / Annual Shade Garden

Why not remove turf entirely in favor of other shade-loving plants? There are plenty of stunning perennials and annuals that don’t mind a bit of darkness. Visit our garden center and speak with our knowledgeable staff. We have an extensive selection of shade plants available and can help you make choices that will best suit your landscape conditions.

  • Mulch

Mulch is an excellent turf alternative for shady areas especially under a shallow-rooted tree where it can be difficult to grow anything. Mulch can also help you define paths to walk through the shade garden and will prevent mud from becoming a problem on those paths. You can opt for wood nuggets, shredded bark, gravel, river rock or even artificial mulches in a variety of colors. 

It can be a challenge to grow grass in the shade, but if you choose the proper type of grass and care for it well, you can cultivate shade-loving turf. If you’d rather not fuss with it, there are plenty of amazing alternatives that can make even the darkest corner of your landscape shine more brightly.

Beetle Mania

It’s hard to forget the years that we’ve been plagued with Japanese beetles. These ravenous creatures can destroy your lawn, garden and good nature in one season by eating away precious time and money invested in our landscapes. As they know no boundaries, Japanese beetle control methods are most effective if neighborhoods band together in their efforts. So, rally the troops! 

Identification & Damage 

Japanese beetles are a problem at two stages of their life cycle: larvae and adult. The larvae, called grubs, are actively feeding from August through October and again in April through May. It is during this time that the grubs are closest to the soil surface feasting on plant roots, especially grass roots. A heavy grub population will result in dead patches of turf that can be lifted like a carpet. Japanese beetle grubs are 1 ½” long, C-shaped and white with a brown head. When gardening, you will almost always find some grubs in the soil. Small populations of grubs can be present in the soil without significant damage to the lawn. If you notice more than a dozen per square foot, however, this constitutes a problem that should be dealt with. 

Adult Japanese beetles have a hard-shell body that is about ½ inch long. They are metallic-green and copper-colored. At this stage, beetles can decimate a plant in record time by skeletonizing the leaves – nibbling off all the foliage between the veins. Adult beetles start to emerge from the soil with a frenzy of feeding, mating and laying eggs. You will find adults feeding in groups in full sun, and they feed on over 300 different species of plants. These insects maintain this frantic level of activity through the first half of August. The females lay their eggs on the ground. When the eggs hatch they dig their way into the soil to feast on plant roots in preparation for winter. As soil temperatures decrease the larvae move deeper into the soil only to resurface and feed on plant roots again in spring. 

Beetle Control Methods 

There are several methods to control both Japanese beetle grubs and adults, some environmentally-friendly and some more harshly chemical. Always read pest control labels in their entirety even if they are listed as organic or environmentally-friendly. These labels are meant for the protection of you, your plants and the planet. 

Environmentally-Friendly Adult Beetle Control 

Effective options for controlling adult Japanese beetles with the least harm to plants and the landscape include… 

  • Manual Removal – Pick off and destroy the feeding adults even if you see just a few. Japanese Beetles produce pheromones that will attract many more to your property, so it is best to pick them off and destroy them right away.
  • Use Non-Attractive Plants – If you have a shade garden you will not have a problem with Japanese Beetles. In sunny areas, choose plants that beetles don’t like.
  • Trap – Pheromone traps lure adult beetles, sometimes hundreds a day, and trap them in a disposable bag. Replace the bag as necessary. Place trap at least 20 feet from the plantings that you are trying to protect to lure the beetles away.
  • Row Covers – Floating row covers of reemay fabric may be placed over plants to avoid beetle damage by keeping the beetles from accessing the plants.
  • Pyrethrins – These insecticides are naturally derived from the pyrethrum daisies. Pyrethrins attack the insect’s central nervous system, producing a rapid knockdown. The residual effect, however, is only 5 days, so several applications may be needed to control severe infestations.
  • Insecticidal Soap – This soap is a contact kill with no residual control, but can be useful for smaller infestations or few beetles.
  • Neem Oil – This oil is an organic control that repels Japanese beetles. Spray early in morning or on an overcast day. Because neem is an oil, you may burn plant leaves if spraying in full sun. 

Chemical Adult Beetle Controls 

When using any chemical controls, read the product label completely and follow application instructions meticulously. It is a good idea to use a spreader sticker so that the chemical will adhere to the plant for the greatest effect. Popular chemical options to control adult Japanese beetles include… 

  • Sevin – This chemical is absorbed through the skin and will kill beetles on contact. It has a 7-10 day residual effect but must be reapplied after a rain. Consult label for recommended time that fruit and vegetables may be consumed after application.
  • Pyrethroides – Synthetic pyrethrin-like insecticides kill on contact and have an 8-10 day residual effect. Fruits and vegetables may be consumed in a shorter time period after application than Sevin.
  • Acephate – This systemic control works by poisoning the plant. The insect dies when the plant is ingested. Must not be used on edibles.
  • Malathion – This chemical must be ingested by the insect, however, this product may be used on edibles. Check label for number of days between last application and safe harvest.
  • Imidacloprid – Sold as a liquid form of Merit, this product is systemic and must be applied at least 20 days before anticipated adult Japanese beetle feeding. Only one application is needed per year. Use only on ornamentals.

Environmentally-Friendly Grub Control 

For truly effective Japanese beetle control, it is also necessary to control the grubs. This can be done in a number of environmentally-friendly ways, such as… 

  • Milky Spore – This biological control effects only Japanese Beetle grubs. Once this bacteria is established it can last in the soil for up to 20 years. It is completely harmless to people, pets, birds, fish and beneficial insects. Apply anytime the ground is not frozen.
  • Beneficial Nematodes – These microscopic worms kills grubs by feeding on, and reproducing in, the grub’s body. This is an excellent choice for a vegetable garden and should be applied after the soil is warm. Late summer/early fall application is best. 

Chemical Grub Control 

Chemical controls can also be effective at minimizing the harm from Japanese beetle grubs. Good options include… 

  • Merit – The granular form of this chemical is a systemic, season-long grub control with a 4-month residual effect, though it must be ingested by the insect. It is applied 3-4 weeks before grubs are actively feeding, mid-May through mid-June. Must be watered-in within 24 hours of application.
  • Dylox – This compound is absorbed through the grub’s ‘skin’ and will kill within 24 hours of application. Use only in late summer through early fall while grubs are still close to the soil surface. Must be watered in. It is active for up to 7 days in the soil.
  • Sevin – In its granular form, Sevin is a contact kill and will not remain active in the soil longer than 7 days. This product is used most effectively from mid-August through mid-October. Must be watered in.

With so many options for effectively controlling these pernicious insects, there is no reason why you need to keep being bothered by Japanese beetles. Once you know more about these insects and their habits, you can easily keep them away.

Succulent Container Garden

Have you noticed how a container garden can really jazz up a front entryway, back deck or porch? Perhaps you’ve thought twice about including this addition to your plantscaping because you just don’t have time every day to water. 

Cheer up! You can plant a container with succulents (plants with fleshy or thickened leaves, stems or roots) and you will not have to worry about watering frequently. Succulent container gardens are relatively carefree, and they’re so easy that you don’t have to limit yourself to just one. If one container makes a statement, several will create a conversation! 

Succulent Container Garden Tips and Tricks

To have the greatest success with your new succulent container garden, consider… 

  • Exposure
    Full sun is a must for all succulents and will help show off their subtle colors and textures. If your viewing location has less than adequate sun, place your succulent garden in a full sun area for the majority of the day and move to your desired location when you have company or time to enjoy it yourself. Remember to move it back out into the sun when company leaves.
  • Containers
    Because succulents do not have extensive root systems, your chosen containers may be shallow. Too much soil can hold excessive water causing the succulent’s roots to rot. Perhaps a strawberry pot would make the perfect focal point at your front door, and many front doors look great with a single shallow round planter sitting on the stoop. If you have several steps to the door, try a pot on each step. How do you want your front entrance to say “hello”?
  • Height
    Think about varying the heights of your containers. Perhaps your containers will require a pedestal or something else for elevation. This could be an inverted pot, a table, shelf or even pot feet. You may even consider hanging your container for elevated elegance. Whatever you choose, it’s important to remember succulents require excellent drainage. Therefore, the containers must have holes.
  • Soil
    All succulents need fast draining soil. Pre-mixed soil is available that is specifically blended for succulent container plantings. You may also use a general all-purpose potting mix and add perlite, coir or sand to increase the drainage sufficiently.

Plants for Your Succulent Container Garden

When making your plant selection, it is fun to let your imagination go wild and embrace the full range of amazing succulents available. As a good container gardening rule of thumb, Use a thriller (something stunning to catch the eye), a filler (a sturdy, reliable choice to fill in bare spots) and a spiller (a trailing plant to blur the container edges) and you’ll never go wrong. 

Succulents come in an extensive variety of colors, striking shapes and varying sizes. As when planting any container, evaluate plant color, texture and shape when making your selections. You may feel overwhelmed when choosing your plants. If you can’t decide, here is a simple “recipe” for planting one 16″ container to be seen from all sides. Maybe it will give you some ideas: 

  • 1-thriller (Euphorbia tirucalli ‘Sticks on Fire‘) planted in the middle.
  • 3-fillers (Kalanchoe blossfeldiana) to surround the thriller and provide texture or color contrast
  • 5-spillers (Sempervivum arachnoideum) to drape over the container’s edge.

As an extra bonus, many succulents bloom, adding extra unexpected beauty. Blooms can be few and far between, however, but they will be exciting and rewarding when they are spotted. 

The Importance of Topdressing 

After planting, gently brush off any residual soil from the succulents’ leaves. Add more interest by topdressing the container. This is a layer of material will give your container garden a finished appearance. Desert type plants look great with a thin layer of light tan-colored gravel or red lava rocks. Create sparkle with sea-glass toppings or add a clean, contemporary look to Zen-like or Asian inspired plantings with smooth black river stones. Other popular top dressings include glass marbles, colored aquarium gravel or tiny seashells. You might even add a fairy garden surprise in the container, such as a miniature hut, hidden gnome or other quaint character who will call your succulent garden home.

Most importantly, have fun!

Crape Myrtles

No yard or landscape should be without a crape myrtle, or two, or three or… many! How wonderful to have something that blooms so profusely during that time of year when most other plants are looking tired and worn from the summer heat and drought. The versatility of this plant makes it suitable for many types of yards and many uses, and once established, they will go on to add charm and delight to the landscape for many years.

About Crape Myrtles

Crape myrtles bloom in late summer and can be found in flower colors of pinks, lilac, white, reds and purples. Requiring very little maintenance once established, crape myrtles need a full sun location to thrive and they do not like wet feet. Keep these needs in mind when selecting a site to plant them. They will require some supplemental watering for the first year or so to get off to a good start and develop good roots. Crape myrtles are also pretty much pest-free, except for aphids on occasion and these are easily controlled with an insecticidal soap spray. Some varieties are more susceptible to powdery mildew than others but most of the newer varieties are more resistant to this fungus problem.

Planting Crape Myrtles

Although tolerant of a wide range of soil qualities, crape myrtles grow poorly in wet locations so be sure to select a well-drained planting site. Late spring to early summer is the best time to select and plant your new crape myrtles while they are actively growing and can settle in quickly. Plant at or slightly above ground level, spreading the roots out slightly and using mulch to protect and shelter the roots after planting. They do prefer a slightly acid soil.

Crape Myrtle Types

Crape myrtles can be found in shrub, multi-stem tree and single trunk tree forms. For best results select a cultivar whose growth characteristics and ultimate mature size fit your intended use. Planting a shrub- or tree-like crape myrtle in an area of limited space will require yearly pruning to keep it from outgrowing its place. Single- or multi-stemmed tree-form crape myrtles are ideal as flowering specimen trees or as small, flowering shade trees near patios, walkways and entrances. Shrub forms make an excellent accent in a shrub border when planted in groups. Dwarf plants are effective as large groundcovers, perennial bedding plants or container plants providing vivid, summer-flowering interest.

Pruning Crape Myrtles

If adequate room is provided, little pruning is required except to maintain shape or remove any dead or crossing branches. Remove any suckers or water sprouts to maintain tree forms and elegance. Blossoms are produced on new growth so you can prune anytime the plants are dormant through the winter.

With so much to love about these plants, there’s no reason not to add one to your yard this year! And next year, and the year after that, and the year after that…

More Than Just Mulch

Not only does mulch add a decorative finish to your flower beds, it also keeps the soil cool and moist and thus reduces the need for watering. By using a pre-emergent herbicide with mulch, weed seeds are discouraged from germinating and growing. But which mulch should you use?

Types of Mulch

There are several types of mulch to choose from, and each type can give your landscaping a different finishing touch.

  • Pine Bark and Nuggets
    These types of mulches release acid when they break down. Pine mulches should be used around plants that need a more acidic soil. Use around azaleas, rhododendron, pieris japonica and holly.
  • Shredded Hardwood
    This is by far the most popular mulch. It has a dark color and knits together well so that it does not wash away. This mulch is often available in different colors, including black, red and brown.
  • Cypress
    This long-lasting mulch has a pleasant fragrance. Cypress mulch also knits together well, and it is thought to repel insects.
  • Artificial Mulch
    Artificial mulches may look like bark, nuggets or hardwood shreds, but they are really shredded rubber or similar materials. They are often dyed in natural tones to mimic organic mulches, but could also be dyed in outrageous colors. These mulches do not break down and will not benefit the soil, but they do not need replacing as often as organic mulches that will eventually decompose.
  • Yard Waste
    Many gardeners use yard waste such as shredded leaves, grass clippings or pine needles as mulch. While these can be effective mulches to conserve moisture and repel weeds, and they are certainly more economical, they do not have the refined look of wood mulches. Yard waste mulches will also decay and discolor much more quickly than wood mulches.

Using Mulch

No matter which mulch you choose, it is important to use it properly. It is recommended that mulch be applied 2-3 inches deep around plants, in flowerbeds and in garden areas – less depth will not be as effective to shield and protect the soil, while deeper mulch may actually protect too much and could restrict water from entering the soil. Take care not to pile mulch directly next to stems and trunks, which could invite insects and rot to invade the plant.

Over time, mulches will decay and compact, at which time they can be removed and added to a compost pile, or simply turned and worked into the soil around the plants they’ve been protecting. To preserve mulch a bit longer, raking and turning it over will refresh its color and reduce compaction.
