Deterring Deer

Deer may be beautiful and elegant, but they aren’t always welcome in the garden. Even just a few visiting deer can tear up a landscape, eat an entire crop, destroy a carefully cultivated bed and cause other havoc, such as creating a traffic hazard, damaging bird feeders or leaving behind unwanted “gifts” on sidewalks and pathways. But how can you keep deer out of your yard and away from your garden and landscape?

Popular Deer Deterrent Techniques

People try all sorts of home-grown methods to keep deer from destroying their landscape and gardens. Some of the more common tactics include…

  • 8 ft. fencing, including wire or electric fences
  • Big, loud dogs on guard in the yard
  • Deer repellents such as Liquid Fence, Deer Scram
  • Predator urine or other anti-deer scents
  • Motion detectors connected to lights or sprinklers
    Milorganite is a granular fertilizer that deters deer

All of these methods work but are limited in their effectiveness. Fencing is costly and unsightly. Repellents and urine wash away and need to be reapplied. Sprinklers or lighted areas can be easily avoided. So what can you do to keep deer away permanently?

Deer are creatures of habit and they are easily scared. Anything you can do to mix up their habits or make them think there is danger nearby might be enough to make them go elsewhere in search of food. But deer aren’t foolish and if they realize the danger isn’t real, they will return. Therefore, you must rotate any scare tactics you try and reapply repellents frequently. This can be a lot of work to keep your garden safe, but you can make your garden do the work for you.

Plants Deer Won’t Like

While deer in large herds with insufficient food will eat almost any garden vegetation, particularly in harsh winters, you can opt for plants that aren’t popular with deer to minimize deer damage. At the same time, avoid planting favorite deer plants, such as azaleas, rhododendrons, yews, roses, Japanese maples, winged euonymous, hemlocks and arborvitae, as well as any edible garden produce.

So what can you plant in your landscape to discourage deer? There are many attractive plants deer will avoid, including…

Trees

  • Colorado Blue Spruce
  • Dragon Lady Holly
  • Douglas Fir
    Green Giant Arborvitae
  • Japanese Cedar
  • San Jose Holly
  • Serviceberry
  • Scotch Pine

Perennials, Shrubs & Climbers

  • Amsonia
  • Barberry
  • Bearberry
  • Boxwood
  • Caryopteris
  • Creeping Wintergreen
  • European Privet
  • Japanese Plum Yew
  • Leucothoe
  • Rose of Sharon
  • Shasta Daisy
  • Yarrow

Try using these less deer-friendly plants to create a dense border around your yard and garden area, and deer will be less inclined to work their way toward the tastier plants. When combined with other deterrent techniques, it is possible to have a stunning landscape without being stunned by deer damage.

 

Autumn: Why Plant Now?

Although many gardeners plant trees and shrubs in the spring, knowledgeable gardeners plant in the fall to take advantage of all this fabulous season has to offer. But why is fall planting better than spring planting?

  • Stress Reduction
    Transplanting causes stress as plants are removed from containers, balls or established locations and changed to new locations. Planting in the fall, when a plant is entering dormancy and is generally hardier and sturdier, reduces this stress so the plant can thrive.
  • Establishing Strong Roots
    Fall planting “establishes” trees and shrubs by encouraging root growth. Because the soil is still warm, the roots continue to develop until freezing, though the upper parts of the plant are already dormant. When transplanting in the spring, the developed roots are active and delicate tips or rootlets, as well as buds and new leaves, are more easily damaged.
  • Weather Resiliency
    Trees and shrubs planted in the fall are better able to withstand the rigors of the next summer’s heat and dry conditions because they have much longer to develop healthy roots systems and become thoroughly established. This is especially critical in dry climates or areas prone to drought or irregular rainfall.
  • Faster Maturity
    The “head-start” of fall planting results in a larger plant in less time, helping create a mature landscape without waiting for smaller plants to catch up. This can be especially critical when replacing dead or damaged plants in a mature landscape to avoid a gap or uneven look.
  • Water Conservation
    Planting in the fall saves watering time and promotes conservation by eliminating daily watering. Cooler temperatures with the addition of both morning and evening dew contribute greatly to soil moisture availability in fall without as much supplemental watering.
  • Color Confirmation
    Fall is the best time to see a plant’s autumnal color. Planting in the fall eliminates the surprise of the wrong color or unexpected shades that may not coordinate with nearby plants. By planting in autumn, you’ll know exactly what you’re purchasing and planting, and you will be able to match better with your existing landscape.
  • Saving Money
    Last but definitely not least, buying your beautiful trees and shrubs in autumn can save big money. We discount prices on trees and shrubs to create room for holiday season materials and pass the savings on to you. Selection may be more limited later in fall, however, so don’t wait too long to take advantage of great savings.

Autumn can be the ideal time to plant trees and shrubs, whether you are adding to your landscape, replacing plants or starting a whole new look. If you plant in autumn, you’ll be amazed at how lovely your landscape will look next spring.

Plant a Tree This Fall

There are so many reasons to add a new tree to your landscape this fall that it’s hard to find a reason not to.

Just think about it, trees will…

  • Beautify the Environment
    Trees add texture and color to the landscape. They soften the harsh lines of buildings and driveways, while their foliage and blooms add seasonal color changes and variety.
  • Stabilize Soil
    Tree roots prevent soil from blowing or washing away, minimizing erosion and providing protection for the surrounding landscape.
  • Provide Wildlife Habitat
    Trees provide shelter and food for birds and numerous small animals, including squirrels, raccoons, insects and more.
  • Make Food
    Many trees provide fruits, nuts, seeds, sap and berries for human consumption. Wildlife will also rely on the food provided by trees.
  • Create Oxygen
    Through photosynthesis, trees take in carbon dioxide, carbon monoxide, sulfur dioxide and other poisons from our air and release pure oxygen for us to breathe. One tree can produce enough oxygen for 10 humans for one year!
  • Filter the Air
    Trees act as giant filters trapping dust and pollution particles with their leaves and bark until the rain washes the particles away.
  • Cool the Air
    Air will remain several degrees cooler in the shade of a tree canopy. This is accomplished by not only by blocking the sun’s rays but also through transpiration. Tree leave transpire, or release moisture, which cools the surrounding air. A large tree can release as much as 400 gallons of moisture from its leaves daily.
  • Reduce Utility Bills
    Deciduous trees planted on the south and southwest sides of a home will shade the structure during hot summer months and reduce air conditioning or other cooling needs. In the winter, with the leaves fallen, the sun is able to warm the structure, reducing heating bills.
  • Reduce Noise Pollution
    Strategically planted, trees can dramatically reduce the volume of unwanted noise from loud neighbors, nearby businesses or car traffic.
  • Hide undesirable views
    Purposefully sited, trees can camouflage unattractive views and create privacy, providing a natural sanctuary in your yard.

In our area, fall is just about the best time of year to purchase and plant a tree. The soil is warm, air temperature is cool and morning and evening dew increase available moisture to nurture a new tree. Stop in and see our extensive collection, and we can assist you in choosing the tree that is perfect for your landscape and lifestyle needs.

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!

Audition Some Autumn Bloomers

Extend the beauty of your garden with vivid autumn-blooming perennials. When you think of fall-blooming plants, don’t stop at mums – there are many perennials that can add color to your yard at this time of year.

Top Autumn Bloomers

While there are different autumn-blooming perennials for different growing zones and climate conditions, some of the most popular and widespread options include…

  • Fall Daisies
    For fall daisies (besides daisy mums!) grow Boltonia or Nippon Daisy. Boltonia is a tall (3-4′) grower, suitable as a background plant. White or pink daisies are borne in profusion atop fine grey-green foliage. The Nippon Daisy (Chrysanthemum nipponicum) is covered with large crisp white daisies in October. Both love lots of sun and make excellent cut flowers.
  • Autumn Sedums
    Bold-foliaged sedums provide texture as well as color in a sunny place. Sedum ‘Autumn Joy’ is the most well known. It has coppery-pink flower heads. Sedums ‘Brilliant’ and ‘Stardust’, with soft pink and white flowers respectively, are also attractive. For a totally different color combination plant sedum ‘Vera Jameson’. It has gray-purple foliage with rose pink blooms and looks stunning when planted with Blue Fescue, Artemesia Silver Mound and other silver-foliaged plants. As an added bonus, all the sedums are attractive to butterflies.
  • Autumn Asters
    Asters are another fall bloomer that butterflies love. These perennials like sun and moist, well-drained soil. There are many colorful aster varieties in shades of pink, purple, blue and white. Some favorites include tall-growing aster ‘Alma Potschke’ with bright pink flowers, blue-flowered aster ‘Professor Kippenburg’ and low-growing aster ‘Purple Dome’ with its deep purple blooms.
  • Autumn Goldenrod
    Sunny yellow goldenrod (Solidago) is another bright addition to the fall garden. Wrongly blamed as the cause of fall allergy problems, goldenrod has rightly taken its place in the fall garden. It looks particularly effective combined with blue flowering plumbago, purple asters and ornamental grasses.

Fall Bloomers for Shade Gardens

Even shade gardeners can enjoy late blooming perennials. Tall growing Japanese Anemones are a stately addition to the perennial garden. Bloom colors range from pure white to various shades of pink, and flowers can be single, semi-double or double blooms. Anemones grow well in light to moderate shade and spread quickly to form large clumps, filling in space vacated by spent summer plants. Turtlehead (Chelone) is another fast spreader for shade. Rose pink flowers cover the tops of the plant from early September to October. For a deeply shaded location, try Toad Lily (Tricyrtis), which has clusters of beautiful cream flowers, spotted with maroon along its upright stems. For light shade, plant Blue Cardinal Flower (Lobelia siphilitica), whose intense blue spikes can be admired from mid-August until frost.

No matter what type of garden you have, the end of summer does not need to mean the end of colorful blooms. Instead, just opt for amazing fall bloomers and enjoy brilliant color even longer!

The Fall Vegetable Garden

Fresh vegetables don’t have to end as the days grow shorter – fall is a great time to plant an autumn garden to extend the growing season. Many vegetables such as broccoli or cauliflower are of a higher quality when grown in the fall, while others, like kale, develop better flavor after a frost. Spinach, chard, kale, collards, mustard and rapeseed all grow rapidly and flourish at the end of the season, ideal for autumn gardening. Loose-leaf lettuces do well, too.

To prepare your bed, immediately pull out whatever plants have finished producing. Spade or till the soil to a depth of 6-8 inches, rake the area lightly and work in a light application of composted manure or 5-10-5 fertilizer to provide adequate nutrition for rapid-growing fall veggies.

Broadcast a mixture of seeds like mustard, kale and rapeseed, or combine seeds of several types of lettuce like curly leaf, red leaf and oak leaf to allow you to harvest your salad already mixed. It works best to plant greens in blocks or wide rows, because they’re easier to harvest and you’ll have fewer weeds. If you plant blocks each time a new space opens up, you’ll have staggered plantings that can produce over a long time.

Some autumn vegetable varieties will tolerate cold better than others. Read seed packets before you purchase them to determine what will be best in your area, but don’t be put off by such notations as chard’s taking 60 days to mature. The greens are good when they’re younger, too.

Water seeds after sowing and keep the ground evenly moist until the seedlings are up and growing. Seedlings may also need to be sheltered from extreme heat. Protect them by shading them from the sun with Reemay fabric until they are established.

Although insects tend to be less bothersome in late fall, some vegetables in the cabbage family, including mustard, kale and collards, may attract cabbageworms. Apply Bt (Bacillus thuringiensis) sprays for an organic method of control. As the plants begin to fill out, thin them enough to allow air to circulate and dry off moisture. This helps prevent insect problems too.

Harvest your fall vegetables as soon as the plants reach edible size. Even after the first frosts, you’ll be able to keep harvesting to enjoy the yield of your extended-season garden.

Fall Lawn Care

Fall is the best time of the year to overseed your existing lawn or establish a new lawn. If your lawn is a bit thin, has bare patches or needs good care, now is the time to take care of it so it can become thoroughly established before warm temperatures arrive in spring.

Overseeding A Weak Lawn

A weak lawn may have thin or scraggly patches, seem overrun with weeds or have bare patches that are difficult to keep green and lush. Overseeding can help eliminate these problem areas and create a more consistent, luxurious lawn.

  1. Spray broadleaf weeds with a selective herbicide and wait 2 weeks for the weeds to disappear. Several treatments may be necessary if the yard is thick with weeds.
  2. Take a soil sample of your lawn to determine the pH. A garden extension service can help determine pH levels, or home test kits are available.
  3. Mow shorter than normal and rake clean to remove unnecessary debris that may keep seeds from reaching the soil.
  4. Core aerate if you have compacted soil or heavy thatch. Remove the cores and dispose of them properly to keep the soil light and airy for seeding.
  5. Apply starter fertilizer and lime if determined to be needed by the pH test, or choose a grass type that will thrive in your soil’s conditions.
  6. Dethatch your lawn if thatch is thicker than ½ inch. This can be done with heavy raking or a special dethatching rake may be necessary in extreme cases.
  7. Overseed with the proper seed. If core aerating, lightly topdress with topsoil or humus.
  8. If needed, cover the freshly seeded area with netting or hay to discourage birds or other wildlife from consuming the seed before it grows.
  9. Water daily until grass has germinated, then soak once a week to encourage deep root growth.
  10. Fertilize in late fall with fall fertilizer.

Seeding A New Lawn

If you have no existing lawn or the entire ground is overrun with nothing but weeds, it may be best to start from scratch and create the lawn of your dreams.

  1. Kill existing vegetation with nonselective herbicide. If you want to preserve nearby trees or shrubs, take steps to protect that vegetation from the treatment.
  2. Take a soil sample of your lawn to determine the pH. A testing kit can provide a good pH estimate, or a gardening center or garden extension service can provide a more precise evaluation.
  3. Prepare soil by breaking up the surface with a rake or spade using a crisscross pattern. All large lumps should be broken up, and any large rocks should be removed.
  4. Broadcast starter fertilizer, lime and gypsum as determined by the pH test. This will provide a nutrition boost for fresh seeds.
  5. Spread topsoil or humus to a ½ inch depth for appropriate planting.
  6. Rototill to a depth of 4 inches and grade smooth. This will mix all the top layers together for uniform soil and nutrition, ensuring even turf growth.
  7. Sow proper seed and mulch lightly with salt hay to control erosion and conserve moisture.
  8. Water daily until grass has germinated, then soak once a week to encourage deeper root growth to resist droughts and repel weeds.
  9. Fertilize in late fall with fall fertilizer to provide nutrition throughout the season.

Which Seed?

Not every lawn will thrive with the same type of grass seed. Allow our staff to help you select the seed that best suits your needs, soil type and planting conditions. Apply at the recommended rate and incorporate into the top ¼” of soil. Do not bury the seed or it may not germinate evenly.

No matter what the condition of your lawn, fall is the best time to take steps to help it rejuvenate so you have an amazing lawn to enjoy in spring.

Repotting Houseplants

Fall is an excellent time to repot many houseplants. Potted plants that have been growing outdoors during the summer have probably grown quite vigorously due to the high light levels and greater humidity. If the top growth of the plant has increased in size by 20 percent or more, it probably should be transplanted into a larger container so the roots can stretch and settle comfortably.

Before You Repot

Before repotting, check the plant and the soil carefully for insects.  Add systemic granules to the soil and spray the leaves with an insecticidal soap to remove any unwanted pests. If an insect infestation is particularly bad, it may be necessary to remove most of the plant’s soil and replace it with fresh potting soil. Avoid using soil from the garden, however, which will harbor insect larvae and eggs as well as weed seeds and other material you do not want in your houseplants.

Acclimating Plants

Bring your plants indoors well before any danger of frost for proper acclimation to the indoor environment. The change in light levels and humidity could shock more delicate plants, and they may wilt temporarily or drop leaves before they adjust to the new conditions. If possible, bring them in just a few minutes at a time for several days, gradually increasing their indoor time to several hours before keeping them indoors all the time. Flowering tropicals will also benefit from cutting back some of their foliage to avoid shock before being brought indoors.

To help houseplants overcome the transition from outdoors to indoors, position them in a bright, sunny area and consider adjusting indoor temperature and humidity controls to more closely mimic outdoor conditions. Make adjustments slowly and gradually, and the plants will adjust.

Time to Repot

Once your houseplants are adjusted to their indoor fall and winter environment, they can be safely repotted without adding to their stress. Repot the plants early in the day, and move them to a slightly larger pot. Avoid jumping several pot sizes, which could lead to excessive root growth while the foliage is neglected. Be sure to fertilize and water the plants appropriately to provide them proper nourishment as they settle into new pots. Do not expect luxuriant foliage growth right away, however, as it will take some time for the plants to begin growing again, especially in fall and winter when most houseplants are entering a dormant, slow growth period.

By repotting your houseplants in fall, you can help healthy, vigorously growing plants adjust to a new environment and continue their growth with ease in a new, larger, more comfortable pot.

Fall Horticultural Oil Application

Autumn is an excellent time to apply horticultural oil. The oil smothers many soft-bodied insects and hard-shelled scales that are impenetrable to many insecticides, and can therefore help control some of the most stubborn insect populations. But is it right for your plants?

About Horticultural Oil

Horticultural oil, or hort oil, is typically derived from petroleum, and is a type of ecologically-friendly mineral oil. Some cottonseed and soybean oils can also be effective horticultural oils. Emulsifying agents are typically added to these oils so they can be mixed with water and used as a spray, which helps distribute them evenly over plant foliage to be most effective.

Pests That Don’t Like Horticultural Oils

Different types of horticultural oils can be effective against many unwanted garden pests, including…

  • Spider mites
  • Aphids
  • Whiteflies
  • Mealy bugs
  • Psyllids
  • Lace bugs
  • Caterpillars

In addition to smothering the larvae or insects directly, the heavy oil also makes it difficult for many insects to crawl therefore starving them to death and preventing them from spreading diseases from plant to plant. Additionally, the oil repels many insects looking for winter homes. The oils also act as fungicide against powdery mildew, rust and leaf spot on some plants.

Applying Horticultural Oils

Application of horticultural oils is easy, requiring only a simple hose-attached sprayer. Because oil and water do not mix, frequent agitation by shaking is required even if the oils are mixed with other agents to be more sprayable. These products are most effective if applied when plants are dormant, since oil-based products can burn and harm actively growing foliage, buds, flowers and fruit. Some lighter weight, summer-formulated oils are available, but they should be used only sparingly and only if absolutely necessary. Autumn and winter are the best seasons to apply horticultural oils when insects are a problem, though autumn applications can occasionally cause problems with plants dying back and other winter damage. Because the oils can evaporate and dissipate quickly, they should only be used when insects are present, otherwise they will be ineffective. In freezing weather the oil coverage will be inconsistent, so cool but not bitterly cold temperatures are best.

Of course, always follow the instructions for proper application rates, plant sensitivity and ideal weather conditions to ensure the most effective treatment. Because these oils are still pesticides, protective gear such as gloves and goggles should also be worn to avoid accidental irritation or more severe contamination.

Using hort oils can be a great way to control insects on your plants, but only if the oils are used appropriately. Come in for a consultation to see if these products can help end your insect problems.

Japanese Beetle Reduction Methods

Japanese beetles can be a scourge of the garden and landscape, but what can you do to keep these pests at bay?

About Japanese Beetles

Japanese beetles (Popillia japonica) spend their early lives as underground grubs eating turf grass roots. They prefer well-watered, healthy perennial ryegrass and hard fescues in full sun. Emerging as adult beetles in mid-June through July, they begin feeding on over 200 varieties of plants, including shade and fruit trees, shrubs and ornamentals. They also mate and the females lay 50-70 eggs in the soil.

The eggs hatch in the fall and white C-shaped grubs begin eating roots. Autumn is the best time to check your lawn to see if the grubs are present. Dig several one-foot squares 6″ deep in your lawn, turning over the turf and looking for these distinctive grubs. If you find them, taking action immediately can help control the infestation.

Reducing Japanese Beetle Populations

Non-chemical preventative treatments include spraying beneficial nematodes such as Heterorhabditis or Steinernema onto moist lawns and soil in September. Nematodes, naturally occurring soil organisms, are parasitic to soil grubs and many insect larvae, including Japanese beetles. Spray in the evening and ensure the soil is moist to at least 6″ deep. One product, Lawn Guardian, contains two types of nematodes; one lives deeper in the ground to give a “double whammy” to the feeding grubs.

Natural predators include ground beetles, ants and Tiphia, a parasitoid. Applying Bacillus popilliae Dutky to the soil causes “Milky Spore Disease” to the grub. Chemicals to control the grubs include trichlorfon, imidacloprid, halofenozide or thiamethoxam, so look for pesticides that include these compounds to help eliminate Japanese beetles. Neem oil can also be helpful to control these pests. As always, read and follow the directions carefully when using any type of chemical pesticide.

In the garden, row covers can help minimize Japanese beetle populations during the growing season, but this can also reduce crop productivity as fewer flowers are pollinated. Still, if an area is heavily infested with Japanese beetles, a smaller crop may be a better alternative than accidentally nurturing these pests. If only a few beetles are present, hand-picking them off plants and killing and disposing of the insects – toss them in a bucket of soapy water – can keep the populations manageable.

For the latest information and updates on Japanese beetles, as well as more control tips, contact your favorite garden center or County Agent.
