Dealing With Drought

Because plants require moisture to grow and thrive, your garden will probably suffer during periods of low rainfall and intense heat. Insufficient soil moisture will result in smaller flowers and fruit, stunted plant growth, decreased root development and increased plant disease and insect damage. Fortunately, there are many things that you can do to minimize the impact of drought on your garden.

Save Your Soil

Soil is like a sponge that holds and releases all the ingredients that your plants need to survive. Soils that drains quickly, such as sandy or rocky soil, will speed up and increase the effects of drought as water flows away from plant roots. The best way to correct this problem is to amend your soil with organic matter. Amending your soil adds to its moisture retaining ability, adds nutrients essential for plant health and increases soil aeration for ease of root growth. Good choices include:

  • compost
  • composted manure
  • composted or shredded leaf litter
  • mushroom soil
  • dried grass clippings
  • earthworm castings

First, amend soil immediately around plants, in landscaping beds and in the garden, but aim to amend all your soil and lawn eventually to improve its condition and drought-resistance.

Choose Drought-Tolerant Plants

Drought-tolerant plants are adapted to grow well in regions of low rainfall. These plants require minimal water to survive. When planting, try to group plants with the same water requirements together in an area best suited to their tolerance. Plants best adapted to dry conditions include:

  • locally native plants
  • plants with deep taproots
  • plants covered with hair
  • tiny leaved plants
  • succulents and cacti

Swapping out just a few water-hogging plants for more drought-tolerant options in your landscape can have a remarkable impact on saving water and still having a lush garden.

Use Drought-Friendly Watering Techniques

During a drought, you will need to water your garden, flowerbeds and lawn more thoughtfully to keep them well-watered but without waste or excess evaporation. The best way to water a garden is by drip irrigation or a soaker hose. Soaker hoses allow deep watering without runoff. Moisture goes directly into the soil where every precious drop can be absorbed by plant roots. With conventional overhead watering methods, about 35 percent of the water used is wasted due to evaporation. Time saving tip: Install a timing device with a moisture sensor to automatically turn your irrigation system on and off as required relative to any rainfall.

Sprinklers should be used primarily for lawns. Newly seeded or sodded areas must be watered daily during the summer months until established, then frequently through the first growing season. Rain gauges are good for checking the amount of rainfall or for sprinkler placement. Lawn Tip: Do not cut lawns shorter than 3” in the summer. This will shade the soil surface to allow the soil to remain cooler. Also, use a mulching mower to return moist clippings to the soil.

Containers and hanging baskets should be checked for watering every day. Watering wands are used for watering containers and hanging baskets, as they give a gentle spray without splashing the soil. Container Tip: When planting your pots and hanging baskets, incorporate moisture retaining polymers into the soil. When the soil starts to dry it will pull from this reserve.

Make Use of Mulch

After watering, you will want to conserve as much soil moisture as possible. Place at least 2-4 inches of mulch on the soil surface in the planting bed. Mulches help prevent soil moisture evaporation and reduce surface runoff, as well as minimizing weeds that would compete for any available moisture. Ideal mulches include:

  • wood chips
  • shredded bark
  • pine needles
  • grass clippings
  • decorative rocks
  • synthetic mulches

With some thoughtfulness about your plants’ watering needs and how to meet those needs, it’s easy to deal with drought conditions without sacrificing your plants.

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…

Protecting Our Pollinators

Every garden requires pollinators, and bees are among the finest. Without them there would be limited flowers and far fewer fruits and vegetables. Did you know that about 30 percent of the food we eat depends on the pollination of bees, including onions, cashews, coffee, carrots, chocolate and vanilla? If we don’t protect these prolific pollinators, our landscapes, gardens and diets will be irrevocably changed.

About Bees

Although there are many bees that are great pollinators, like carpenter, mining, sweat and cellophane bees, some of the most well known and easily identified bees are the honeybee and bumblebee. Both of these bees live in social colonies and are cavity nesters. Because these bees are active all summer long, they require a constant supply of floral nectar close to their hive and they thrive in flower gardens, orchards and other areas with abundant blooms.

Unfortunately, both these types of bees – along with many others – are disappearing rapidly, and two key threats are to blame.

  • Habitat Loss: As more natural habitat is lost to development, there are fewer nesting locations and inadequate food supplies for bees. While meadows developed into resorts and parks disappearing for strip malls are obvious examples of development, other less visible developments that can hurt bees include widespread use of flower cultivars that do not produce adequate nectar, eliminating critical bee food sources.
  • Pesticide Drift: Widespread, abundant spraying of pesticides to protect crops, lawns and parks can inadvertently hurt bees. Stronger pesticides can kill bees directly, while less potent toxins can contaminate nectar and will gradually build up to fatal levels in bees’ systems. Even if pesticides are not sprayed in areas where bees are abundant, high level spraying can easily be spread by wind patterns into critical bee habitats.

Inviting Bees to Your Garden

Fortunately, it is easy to bring more bees to your garden and encourage healthy bee populations. To support local bees…

  • Planting a variety of flowers that will bloom throughout the entire summer to provide ongoing food supplies.
  • Opt for native flower varieties that will be more easily recognized and used by bees, instead of introduced flowers that are less familiar.
  • Eliminate chemical use in your yard, as much as possible, including on your lawn, garden and trees, especially while plants are in flower.
  • Provide bees a safe place for shelter and to lay their eggs. A wood pile is suitable, or you can invest in a specialized bee house.
  • Make sure that there is an available water source for your bees. A bird bath or any simple water basin works just fine.

Shrubs for Summer Color

Many gardeners assume that the brightest flowers are only seen in spring, but there are many stunning shrubs that have great color all through the summer. Some feature outstanding blooms while others have equally showy foliage and can brighten up any yard. But which will look best in your yard?

Top Summer Color Shrubs

There are a number of tried-and-true summer-flowering shrubs that never fail to be impressive. Consider these favorites to enhance your landscape all summer long.

  • Hydrangea
    This very popular mounding shrub is an old-fashioned favorite, but it doesn’t have to be just your grandmother’s shrub – there are hydrangeas for every situation and taste. Flowers appear in early summer and can last for several weeks. Choose from pink, blue (use an acidic fertilizer to maintain this unusual color) or white blooms. Large flower heads great for drying or make outstanding arrangements and bouquets when cut. These shrubs do best in light shade or sun. One of the easiest hydrangeas to grow is the native American oak-leafed hydrangea has lobed leaves with fragrant, conical-shaped flower heads.
  • Butterfly Bush (Buddleia)
    This dramatic shrub is truly a butterfly magnet, and hummingbirds love it as well. One of the most fragrant flowering shrubs, butterfly bush blooms from early summer to autumn frost, and different varieties can thrive in a wide range of growing zones. The flowers can be pink, purple, blue, yellow or white, and often feature elegant spiked panicles, arching branches and interesting foliage. These shrubs do best in full sun and come in different sizes to suit different landscaping areas.
  • Spirea
    A generally low-maintenance choice, this shrub features golden yellow to lime-colored foliage all summer with pink or lavender blooms in late spring through summer. Goldmound, Gold Flame and Anthony Waterer are all great cultivars and easy care shrubs growing to about 2-4’ by 3-5’. This truly is the perfect shrub to use anywhere in the landscape, and it can tolerate sun to part shade growing conditions.
  • Rose of Sharon (Hibiscus)
    This is one of the showiest plants of the summer, and Rose of Sharon is also one of the easiest to grow. Dense growing and upright when young these shrubs will spread with age, so take care to plant them in appropriate spaces to avoid overcrowding. The dark green foliage contrasts nicely with large, showy flowers that can be up to 4” across. Flowers open in July and will continue blooming through late summer and into fall. Flowers are sterile, eliminating seed problems. This shrub is ideal to plant as a screen, hedge or focal point in full sun.
  • Blue Mist Spirea (Caryopteris)
    This shrub is a great plant for late summer color with bursts of purple-blue flowers just when many other plants are growing dull. Its low-growing, mounding habit reaches 2-3’ wide by 2-3’ tall. Blue Mist Spirea is easy to grow and can tolerate some neglect. It should be planted in full sun, and will bloom from summer to fall.

With any of these shrubs in your yard, your summer landscape can be just as colorful and eye-catching as any spring flowers or autumn foliage.

Fabulous Hydrangeas for Show-Stopping Summer Color

Hydrangeas and are widely acclaimed for their large, showy blossoms that lend fabulous color to gardens from mid- to late summer. Their luxuriant dark green foliage offers a striking background to their large round or smooth blossoms. All hydrangeas are deciduous, and it’s a sure sign of spring when their tender green leaves begin to appear. Hydrangeas are spectacular when grown as single specimens and are equally fabulous when planted in mixed shrub borders. Some of our favorites…

  • Climbing Hydrangea – An excellent deciduous vine with glossy leaves and cinnamon colored exfoliating stems. White flowers bloom in early July. Easily climbs on masonry, reaching 10-20’ tall.
  • Oakleaf Hydrangea – An upright, irregular shrub that grows 4-6’ tall. Large leaves have excellent fall color. Creamy white flowers in July. Tolerates shade well.
  • Bigleaf (macrophylla) Hydrangea – Blue or pink flower clusters (5-10” across) appear in August. Flower color depends on the pH of the soil. Acid soils produce blue flowers, whereas alkaline soils produce pink blossoms. In garden settings, their colors can be changed by adding either sulfur or lime, depending on the color you want to achieve. Blossoms are produced on last year’s growth, so prune just after blooming.
  • Pee Gee Hydrangea – A small, low-branched tree that grows 10-15’ and arches under the weight of large flower clusters. White flowers bloom in July, turning pink and then brown with the first frost, holding on through winter. Flowers appear on previous year’s growth, so prune right after flowers start to turn pink.

Mopheads and Lacecaps – Which is Which?

Before you get the urge to dash out and buy the first hydrangeas that catch your eye, it’s wise to learn the difference between “mopheads” and “lacecaps.” As peculiar as these names sound, they truly are the names designated to two cultivar groups of macrophylla hydrangeas, and understanding the difference between them can help you choose the flowers you prefer.

  • Mopheads
    Garden hydrangeas, also known as ‘mopheads,’ feature large round flowerheads resembling pom-poms and bloom from mid- to late summer. Mopheads bloom in solid masses, their clusters often so heavy that they cause their stems to droop and bend with elegant arches.
  • Lacecaps
    Lacecap hydrangeas bear flat round flowerheads with centers of fertile flowers surrounded by outer rings of sterile flowers. The fascinating flowerheads of lacecap hydrangeas are also somewhat reminiscent of pinwheels.

You will be delighted with the versatility of these lovely shrubs, so relax and enjoy their beauty!

Crazy for Coneflowers

Beautiful and dependable, Echinacea purpurea, or purple coneflower, is the crowning glory of the summer perennial garden. A member of the Aster family, all Echinacea species are native to North America. The genus Echinacea is derived from the Greek ‘echino’ meaning hedgehog, a reference to the spiny center disc flowers.

Coneflowers are practical as well as gorgeous. They have long been used as an herbal remedy to stimulate the body’s natural immune system. Both plant roots and tops are used in the production of herbal medicines. Echinacea purpurea has traditionally been used for this purpose, but research is being conducted on the nine other species to determine their usefulness for homeopathic treatments.

Cultivating Coneflowers

Coneflowers will thrive in a sunny location, planted in well-drained soil. They are tolerant of nutrient-poor soil, heat and humidity. Echinacea purpurea grows on thick sturdy stems from 3-5 feet tall and generally does not require staking. Coneflowers are long-blooming, the flowers are fragrant and they make a long-lasting cut flower. This is one of the top ten perennials for attracting butterflies to the garden. You may deadhead plants after the blooms have faded to improve their appearance and to encourage a second, but smaller, bloom. You may also leave seed heads in place. In the summer and fall, they attract and provide food for goldfinches and other seed-loving birds. In the winter, the black spent flower heads add ornamental interest as they contrast dramatically with pure white snow.

This perennial is not invasive, but will self-seed if flower heads are left to mature. Cut plants down to the basal foliage, the low growing rosette of leaves, in the spring. Plants should be lifted and divided about every four years or as crowns become crowded.

Where to Place Coneflowers

Purple coneflower is a great addition to the back of any sunny perennial border. Its rose-purple flowers, with their coppery-orange centers, look great with ornamental grasses, Black-Eyed Susan (Rudbeckia) and Sedum ‘Autumn Joy.’ Appropriate usage ideas include: cottage, meadow, prairie, wildflower, native and herb gardens, as well as butterfly gardens and any containers that serve similar purposes.

Favorite Coneflowers

America is having a love affair with Echinacea and several new cultivars are released each year, while popular favorites continue to be top choices.

Summer Watering Tips

As the days heat up, watering can become a dreaded garden chore and too many gardeners use wasteful techniques that use plenty of water but don’t give their plants the moisture they really need. Make watering plants easier and more efficient with the proper practices and tools…

  • Mulches not only make plantings look more attractive, but their most important functions are to help retain soil moisture and minimize weeds, which would also usurp moisture from your plants. Mulch around plants to a depth of 2-4 inches, refreshing mulch as needed to maintain that depth and attractiveness.
  • Watering cans and small containers work great for spot watering plants with different watering needs by hand. You don’t always need to get out a hose or sprinkler to get the watering done.
  • Check to make sure that you have the proper length hose(s) to reach every corner of your garden. Take into account any obstacles in the way, and be sure you aren’t dragging the hose over any delicate plantings to reach more distant dry spots.
  • Add a water wand to the hose to get the water where it’s most needed – the base of the plants – without needing to bend over repeatedly, which can cause back strain.
  • The best time to water is during the early morning hours of a sunny day. This will allow plants to absorb more water before it evaporates when temperatures rise, but won’t leave water to sit on plants overnight when mold can develop.
  • Always water plants and container gardens thoroughly and deeply to encourage deeper, more drought-tolerant root systems. It is better to water less frequently but more deeply rather than more often but with less water.
  • In the landscape, a good rule of thumb is to provide an inch of water per week minimum. Keep track of precipitation with a rain gauge to avoid wasting water by overwatering when Mother Nature does the job.
  • New individual plants that are set out, direct sown seed beds, sodding, etc. often require daily care, including watering, until established. Check moisture levels carefully during this period so the plants are well cared for.
  • Use soaker hoses to provide slow drip watering. This allows plants to absorb water easily without wasting water by evaporating from foliage or spraying into the air. Soaker hoses can even be layered beneath mulch to preserve as much moisture as possible.
  • Pay extra attention to plants in containers and hanging baskets as they tend to dry out faster and with greater frequency. These plantings will likely need to be watered daily or even multiple times a day during heat waves.
  • Place Tree Gators, a drip irrigation bag, on newly planted trees for slow, steady watering that will soak down to the root system without draining away along the surface of the soil.

If you’ll be away on an extended vacation, or even just for a few days, make arrangements with a trusted friend or neighbor to “plant sit” while you are gone. There’s nothing worse than worrying about your garden while you’re away – except coming home to crisp plants that haven’t been watered properly!

Bringing Butterflies to the Backyard

In spring, female butterflies will be mostly concerned with finding their species’ specific host plants on which to lay fertilized eggs. Instinctively, they know they must find plants to ensure that their caterpillars will have appropriate food for survival after hatching. Both male and female butterflies will be looking for flowers with nectar for their own survival. And, they will be searching for shelter from rainy or windy weather, a sunny place for basking, and a source of water. Because many natural butterfly habitats in North America are disappearing at an alarming rate, it is becoming increasingly difficult for butterflies to find these necessities of life.

Starting a butterfly garden can be simple and rewarding if you follow these pointers. The most important thing you can do as a gardener is to plant both nectar and host plants in your garden. Providing host plants for caterpillars to feed on, will allow you to watch the metamorphosis from caterpillar to chrysalis to butterfly. So, do not discourage caterpillars. They may make your garden plants look bad but it’s usually only temporary. Most important – do not use pesticides! You may be killing off the very insects you made the garden for. And, you don’t have to have a large area to get a response. Just a few select plants will spur some action. Choose the sunniest spot possible for your butterfly garden. It could be any size or shape; even a short border will work. A combination of woody shrubs, perennials and annual flowers works best, but using just a couple of plants can still yield results. Planting a section of wildflowers is an easy way to cover a problem area and lure some butterflies to your yard. If you don’t have the room for a garden, fuchsia, petunia or impatiens hanging baskets will attract butterflies as well as hummingbirds.

The following is a list of plants that attract butterflies:

Woody shrubs:

  • Glossy Abelia
  • Butterfly Bush
  • Japanese Privet
  • Honeysuckle
  • Weigela
  • Spiraea
  • Lilac

Protecting Trees From Drought Stress

Summer can be the most stressful time of year for landscape plants with heat and drought being the main offenders. When not receiving sufficient moisture, plants are much more susceptible to insect and disease damage. Trees are the most valuable landscape plants and can be the most difficult to replace, so it is sensible that they should be given priority during periods of drought.

Identify Drought Trouble

Lack of water is not a clear indication of a drought when it comes to trees. Many trees have deep, active roots that can easily survive short periods without rain or moisture, but it is important to notice when they are starting to become drought-stressed. Wilting and curling leaves will appear on drought-stressed deciduous trees. Leaf edges will eventually turn brown and crispy and may drop prematurely. Evergreen needles will begin to turn brown at the tips. As the drought continues, the entire needle will turn brown.

Prioritize Which Trees to Help

Generally, the trees most at risk are those that are newly planted or transplanted, as well as any younger trees. The root system of these plants is underdeveloped or has been damaged by the planting. Trees that are growing in a restricted area should also be of greater concern. This includes trees planted in containers, the narrow grass strip between the street and sidewalk and trees grown adjacent to your house or driveway where they suffer more from reflected heat and have less underground space to spread their roots to collect sufficient moisture. Drought-sensitive plants like birches, beeches, dogwoods, Japanese maples and magnolias should also be given priority during drought conditions.

Watering During a Drought

It is best to begin good watering practices before the tree succumbs to drought stress. Trees need approximately one inch of water per week. If Mother Nature is not supplying it then you should.

It is best for the tree if the required water is applied all at one time to the soil, slowly and deeply. This can be accomplished by using irrigation bags on newly planted or small trees. Trees in a restricted area are best watered with a slow dripping hose placed at the base of the tree and moved frequently for even distribution. For larger trees, a soaker hose laid in a spiral pattern, radiating from the tree trunk out to the drip line, works well.

Take care that if your community has watering restrictions during drought conditions, you follow approved practices to maintain your trees without risking fines or fees from illegal watering.

Tips for Helping Drought-Stressed Trees

  • Always water the soil and not the leaves or needles of the tree.
  • 2-4 inches of mulch placed over the soil, under the tree, from the trunk to just beyond the drip line, will help conserve soil moisture. Do not mound mulch against the tree trunk, which can encourage insects.
  • Water on overcast days, early in the morning or in the evening. Evaporation is slower during these times and more water will soak down to the roots.
  • Fertilizer can injure tree roots during times of limited soil moisture. Avoid using fertilizer during drought conditions. If amendments are necessary, choose compost or other gentle options instead of harsher fertilizers.

You can help your trees resist drought conditions with a little thoughtful care, and they will continue to thrive to help provide shade and beauty in your landscape.
