Windbreaks

Burrrrr, do you remember the winter wind? The season awaits when we’ll once again be zipping our jackets against the cold to keep our bodies warm. Your house feels the same chill you do. Have you ever noticed how much warmer you are when sitting next to a barrier that blocks wind? The same warmth generated by blocking the wind can also happen with your home. As you break the wind that chills you to the bone, your house can also stay warmer with a windbreaker.

Typically for North Carolinians, the winter wind comes from the north and northwest. Winter winds take heat away from the home by forcing cold air into your house through small cracks in the windows, doors, foundation, as well as small unseen gaps in the walls. Reducing the wind’s force on your home will reduce heat loss.

Planting a windbreaker or barrier with a series trees and shrubs located near the home will minimize the wind’s chilling effect. Windbreaks deflect and redirect wind flow lessening wind chill and the need to turn up the heat.

According to the Agriculture Program at Texas A&M, heat savings of as much as 23 percent has been achieved when comparing on homes landscaped with windbreaks than homes without.

Landscape windbreaks typically found in the country consist of evergreen trees and shrubs lined up in straight row or in a somewhat linear pattern. To spice up a home landscape, windbreaks are planted in a more informal arrangement, consisting of mainly dense evergreen trees and shrubs with plants having foliage that extends to the ground.

Ideally, the windbreak allows some air flow. A total block can create a strong vacuum on the leeward side (direction downwind.) Ideally, foliage density on the windward side of the break should be about 60 percent. Also, using species of varying heights and staggered rows will created a diverse arrangement for purpose and aesthetics, offering a natural look.

When planting a windbreak or barrier, they are generally aligned east and west, along the north side of the house. Also consider the ultimate spread of tree or shrub branches, and plant far enough away to prevent their contact with the house. With regards to a planting distance from the house, a general rule of the road is to plant the windbreak away from the house 3 to 5 times the height of the mature trees and shrubs.

A few good choices for windbreaks are Chamaecyparis, Eastern red cedar, oriental arborvitae, rhododendron, as well as yaupon hollies and  yews.

A windbreak of trees and shrubs should be planted longer than the length of the house by more than 10 – 20 feet on both sides. This helps diminish the effects of turbulent winds swirling in around the ends. The wind break can also serve as a privacy hedge.

Button up this fall, both you and your home. It may take a few years for the trees and shrubs to mature enough to offer and heat savings; but if you don’t start today, you don’t benefit tomorrow.

Monthly NC garden chores — October

Fall for me brings the beginning of the new gardening year, and October is fall’s most festive month. October gardening in North Carolina is the reward for all your hard work throughout the year. Now is the time to appreciate your landscape, but do some preparedness as well.

I’m not sure what excites me more, the foliage color change or the additional light from fewer leaves on the trees.

scott_pansies[1]Plant annuals. Kale, cabbages, mustards. Pansies, snapdragons, and violas are annuals are colorful, long lasting, and inexpensive; I’ve often wondered why they’re so underused.

Purchase pansies and violas when the selection is best, as early as September, but wait until late October to plant them. Early October can still be to hot to plant, but don’t wait until then to buy, or the selection will be too scarce. Nurse the plants in a holding area if you have to to ensure you get your top choice.

Gardening with Confidence indoor plantsPrepare your houseplants for winter. Many of us like to give our indoor houseplants a summer vacation outside, but our summer break is about to end. It’s time to bring those plants back inside.

During the summer, you might have found that your plants grew a lot, and errant branches are in need of a little pruning. Herbaceous plants can simply be pinched back, but use clippers on woody stem. Be sure to remove any stems or leaves that are dead or diseased.

Repot plants whose roots are growing out of the drainage holes or at the soil’s surface. Select a container that is only one size larger than the old one; otherwise top growth may be retarded while the roots try to fill up the extra space.

Clean the leaves of dust and dirt that gathered during the summer. This covering can interfere with a plant’s ability to turn light into food. A gentle spray from the garden house and a light wipe with a sponge is usually adequate.

A light application of insecticidal soap is a wise precaution before bringing your plants inside, even if you haven’t seen evidence of pests. Spider mites and other pests thrive in a dry, heated house and will multiply rapidly, if present.

Once inside, locate your plants where they will receive as much natural light as possible. When you water, do so thoroughly but less often in winter than you did in the summer.

Gardening with Confidence  wateringWater in well before winter. If October and November are dry, give perennials a deep final soaking so they go dormant in good conditions. They’ll be less subject to being killed in winter with a drink before they sleep.

Transplant trees and shrubs.  Have you have been waiting to rearrange a few trees and shrubs? Now, with the cooling temperatures, is a good time to begin the process.

It’s best to root-prune this month and transplant thirty days (or more) later. This allows woody ornamentals a chance to recuperate before being transported to their new location. Root pruning stimulates small feeder roots near the trunk. These new roots will be dug as part of the transplant, allowing the tree or shrub to better adapt.

  • Water the soil well the day before root pruning.
  • Prune out from the trunk 10-12 inch diameter root ball for ever inch of truck diameter. Thus, a 2-inch diameter root ball will be root pruned about 2 feet from the trunk.
  • Using a flat spade, begin cutting a trench about 24 inches deep. If you run into large roots, cut with loppers.
  • Continue cutting a circular trench around the tree trunk and water thoroughly.

Plant cool-season vegetables. The cooler fall temperatures bring back cool-season crops. It’s time to plant or seed spinach and collards. Also, cilantro and lettuce will once again thrive in your garden.

Consider trying some new varieties this year, or vary your usual choices. Why not add some red-leaf lettuce? Loose-leaf red lettuce packs a high nutritional value, including being an excellent source of beta carotene.

Gardening with Confidence  Canna FlowerWatch out for canna leaf roller. Cannas are a great accent plant and attract hummingbirds to the garden. Plus, most canna cultivars are hardy in the Southeast and can overwinter in the ground. If you found your canna foliage riffled with holes, you probably have leaf roller. Canna leaf rollers are major pest in the Southeast, causing the beautiful foliage to be unsightly.

After the first frost, cut the foliage to the ground and remove it from the garden. Removing the foliage helps control overwintering pests. Don’t compost, as the pest may winter over.

Divide peonies. If your herbaceous peony has become to big for it’s current location, or if you just want to move or share, it can be divide after first frost.

Prepare beds. It’s also a great time to prepare garden beds for next year.

  • Mark new beds (or the beds you want to extend) with marking paint or a hose.
  • Cut an edge, turning this dirt into the new bed, cover with 8 – 10 layers of newspaper.
  • Cover with about 4 inches of chopped leaves or composted leaf mulch.

Now sit back and let nature take her course. Your bed will be ready for planting in the spring.

Compost those leaves. Use your mower equipped with a mulching blade to chop fallen leaves on the grass. These leaves make a wonderful addition to the garden beds or compost pile.

Appreciate wildlife. Don’t be so quick to tidy up.  The remains of the summer and fall garden give shelter, food and cover for the wildlife while also adding winter interest to the garden beds.

IMG_4180Pictured here is a praying mantis egg case I found one year cutting back my garden, Helen’s Haven. It was at this point I learned to slow down my fall pruning until the spring, when the leaves were cleared away and overwintering wildlife was easier to see.

Water-wise Garden Design

Mixed Border Summer

Waterwise design is not only worthy, but a win-win.

A waterwise garden comprises three gardening zones: oasis, transitional, and xeric.

The oasis zone is the area closest to a water source: drain spouts, rain barrels, spigot, etc.

The transitional zone is the area away from the water source about midway to the end of the property.  Plantings here should be sustainable requiring only occasional supplemental water.

The xeric zone is at the property’s perimeter. These plants should be tough requiring no supplemental water.  This area can be filled with dependable drought-resistant plants.

Designing your garden with waterwise zones, helps make you a more efficient gardener, places plants where they will thrive, while saving resources.  Your garden wins, you win.

Monthly NC Garden Chores — September

Gardening with Confidence  strawberries

Strawberry needs
September (and August) is when the cell size of spring fruit strawberry buds is determined. The more favorable the growing conditions your strawberry’s receive now, the bigger the berries will be next year.

Ensure that your strawberries get an inch of water each week. If nature doesn’t provide this, then plan to supplement with water from the spigot, well, or rain harvester.

If you didn’t fertilizer your strawberries in August, do so in September. For plants that were planted this past spring, apply 4 to 6 ounces of ammonium nitrate (33% nitrogen) or 12 to 18 ounces of 10-10-10 per 25 feet of row.

For plants in their second year of growth, increase the application rate to 6 to 8 ounces of ammonium nitrate or 18 to 24 ounces of 10-10-10 per 25 feet of row.

Spread the fertilizer uniformly in a band over the row, about 14 inches wide. Apply when the foliage is dry. Brush fertilizer off the leaves to avoid leaf burn.

In cases where the strawberries aren’t planted in rows, but rather as a garden border, simply estimate the square footage and apply the equivalent amount of fertilizer. My strawberry is 2.5 feet wide by 10 feet long, which is equivalent to 25 feet of row.

Gardening with Confidence  Azalea

Feeding the hummingbirds
Hummingbirds feeders aren’t necessary if you have enough plants to feed these visitors, but they are a great way to ensure you have a consistent food source for the hummers, and you can place the feeder in a location that is easy to see from your favorite chair, either inside or out.

Gardening with Confidence  Humming bird feeder

Making hummingbird nectar
Making sugar-water nectar to fill you feeder is easy to do. Boil 4 parts water with 1 part sugar. As soon as the sugar dissolves, you can reduce the heat. It doesn’t take long; less than a minute. Let sugar water mixture cool, and fill the feeder. Store any remaining nectar in the refrigerator for up to a week. When the temperatures are hot, greater than 86º F, change the nectar water daily.

Pest
If you find fall webworms in your trees–hickory, walnut, birch, cherry, and crabapple, to name a few, pull them out and dump the caterpillars into a bucket of soapy water. This is a good control measure for those nests within reach. For those nest that aren’t within reach, you may have to resort to spraying. Control webworms with BTK (Bacillus thuringiensis). Apply just to the effected branches; using BTK as a broad spray will harm beneficial insects as well.

Weeds
There never seems to be one weed, they come in multiples, and like to hang in gangs. There’s the sedges, the spurges, the grasses, and the oxalis. There are too just many to mention, and still hope for a happy day.

Stay ahead of your weeds. if you have a problem with poa annua, annual blue grass, as I do in my Raleigh garden, now (early September) is the time to use a pre-emergent such as corn gluten.

Gardening with Confidence LawnLawns
The first two weeks in September are the best times to re-seed cool-season grasses such as Kentucky bluegrass, tall fescue, turf-type fescue. Also our southern gardens will benefit from a core aeration.

Wait to prune
Resist the urge to prune shrubs that seem overgrown after a long summer showing. It’s best to wait until late spring to prune, just before the next growing season begins. Punning now could stimulate new growth that would be too tender to survive an early deep freeze. You may also be cutting off next spring’s blooms, such as azalea and  camellias.

Gardening with Confidence  Roses Longwood

Pruning roses
Fear of cutting next year’s bloom is not a worry with roses, but it’s still best to wait until March. Knock Out roses can be pruned most anytime; particularly when you want to shape the shrub. All types of roses benefit from removal of diseased canes and foliage anytime.

Fall planting
October is a great time to plant or move a tree or shrub. Visit your local garden center this fall when the selection will be at it’s peak. Remember to dig planting hole no deeper than the root ball height, and excavate the hole 2-3 times the width of the root ball diameter.

White Rain Lily (Zephyranthes candida)

White Rain Lily

Name: Zephyranthes candida

Zones: 7 to 10

Size: 6 to 12 inches tall and wide

Conditions: Full sun to partial shade; rich moist soil.

The white rain lily was one of Elizabeth Lawrence’s favorite little bulbs. These fall bloomers like moist loam and don’t want to compete for water. Lovely white crocus-like flowers will open after it rains; the rest of the year, they offer a pleasing, grass-like leaf.  Rain lilies make a nice ground cover, giving a open area garden nice texture.

Rain Lilies are an idea bulb for a rain garden or planted in a  location made moist from receiving overflow water from a drain spout. Rain lilies have a magical quality about them in that they just seem to know from where the water comes: Rain lilies will bloom to the occasion of rain.

If you’ve been gardening in North Carolina for any amount of time, you, no doubt, have observed these beauties in gardens. Why grow a few of your own in your own landscape?
