Heat-Tolerant Summer Lovin’ Plants

So far this year, we’ve been quite blessed with beautiful weather. What was a relatively short and mild winter has given way to a long and lovely spring. For all you gardeners out there, it’s been a great time to work in the yard. And even though summer’s heat will soon be upon us, that doesn’t mean that you have to give up on flowers for the season. There are plenty of heat-tolerant plants out there that will provide color and beauty all summer long. Here’s a list of some of our top favorites.

Lantana- Garden Supply Co.- Cary, NC

If you’re looking for a continuous burst of color all summer long, look no further. You can choose from a bevy of lantanas in just about every shade but blue. Most popular are the low-growing, spreading types, which are great for using in hanging baskets, cascading over walls, or massing in large sweeps. Although some selections boast flowers in solid colors, many have bi-colored clusters. They are notoriously easy to grow and require little attention. Better yet, a  lantana garden is butterfly heaven.  No flowers do a better job of attracting them.

Black Eyed Susan

The Black Eyed Susan is sturdy and easy-to-grow, boasting two to four-inch yellow flowers with a prominent purplish-black cone. These cheery flowers make great cut flowers for indoor arrangements, and actually benefit from a cutting back by producing more flowers later in the season. They grow well in just about any kind of soil, and also attract bees and butterflies to the garden.


The numerous selections of this flower are some of the garden’s most colorful, useful, and easy-to-grow plants. They bloom in late spring, thrive in heat, and tolerate drought. Verbenas are mainly grown for their remarkable length of bloom with most blooming from spring until close to frost if trimmed back once or twice in mid summer. Flower color ranges from white through pink, red, lavender, blue and purple.

Threadleaf Coreopsis (Tickseed)

One of the easiest perennials to grow. Delicate, daisy-like flowers complement fine-textured green foliage on this herbaceous perennial. Blooms, about the size of a nickel, come in a variety of yellows. Tickseed starts flowering in June and lasts through frost, with blooms surging throughout the summer and fall. This perennial is a low-maintenance plant and requires very little care once established.


This “fleshy” annual plant is well known for brilliant flowers in a variety of colors. Plants are low-growing spreaders with thick succulent stems and vibrant, cup-shaped flowers. Portulacas love it hot and dry. You can plant them in poor, even sandy, soil.  They will also self-sow in the garden. Plant them in a rock wall or along a sidewalk and they may show up next year in the cracks and crevices.


This is a plant that is started incredibly easily from seed, flowers very quickly, has a wide range of flower types and colors. Zinnias withstand full sun and heat, make an excellent cut flower, and attracts bees and butterflies.

Spring Lawn Care Tips

Cary, NC-

Growing a healthy. lush green lawn in North Carolina can be a bit of a challenge. Poor soil conditions paired with high heat and humidity during the summer months are well-known contributing factors to our difficult growing conditions. But did you also know that two basic lawn-management practices, mowing and fertilizing, can either “make” or “break” a lawn by promoting good lawn health or opening it up to a weed infestation. Here’s a few tips for establishing a healthy and beautiful lawn in your home landscape.

Sharp Mower Blades

Always mow with a sharp mower blade. Sharp blades cut the grass cleanly, which ensures rapid healing and regrowth. When dull blades tear and bruise the leaves, the wounded grass becomes weakened and less able to ward off invading weeds.

A good rule to follow is to have your lawn mower serviced in late winter or early spring before peek grass growing commences later in the spring. If you haven’t had your blade sharpened in several years, you can be pretty sure that they are in need. Take a peek at your freshly mowed lawn and look at the tips of the cut grass. If you see tearing or ripping, you are in need of some service.

Mowing Height

Mow at the proper height for your lawn. For example, mow tall fescue at 3 inches during the summer months. By maintaining the proper height, you will allow the root system to fully develop, helping the grass tolerate summer heat and stress.

One-Third Rule of Thumb

Follow this mowing rule-of-thumb: Remove no more than one-third of the grass height at any one mowing. Cutting off more than one-third at one time can stop the roots from growing, which is an open invitation to weeds.


Fertilize lawns with the right amount of fertilizer based on soil-test results and at the proper time of year. Cool-season grasses like tall fescue and Kentucky bluegrass should be fertilized in the fall.

Weed Whackers

Avoid trimming grass with a weed-eater near the trunks of trees and shrubs. The rapidly spinning monofilament line can easily damage the bark, exposing it to attack from insects and diseases. Instead, maintain a shallow layer of mulch around the bases of trees and shrubs to help suppress weed growth.

Gloomy Scale

Our friends at Leapfrog Landcare recently shared an interesting article about Gloomy Scale that is valuable information to share here with our Garden Supply Co. readers, too.  Gloomy Scale is a tiny bug that infects the healthy tissue of maple trees, especially the soft maples such as boxelder, red maple and silver maple. Grape, soapberry, native hollies, mulberry, sweetgum, and buckthorn may also be infested. And if left untreated, these little buggers can cause all sorts of havoc.

Seems that Gloomy Scale insects have been spending the winter snuggled up in their arboreal homes, and are about ready to resume development next month with their first offspring crawlers showing up in May. Crawlers are produced until the middle of August at which time practically every stage of development can be found. Males emerge in August and September and mate with new females. There is one generation per year.

Here’s what Greg, of Leapfrog Landcare shared.

“Gloomy Scale is a parasite that sucks the sugar out of the sap of Maple trees and when they multiply each female can reproduce up to 500 more!!! If a tree has only 50 females of this tiny bug and each of them reproduce 500 more, then that tree now has 25,000 or more Gloomy Scale that are all drinking from the tree. They keep populating the tree until it is just covered one scale on top of the other and it makes the tree trunk and limbs turn black and eventually as the infestation turns severe the tree can’t force enough sap past them to get all the way out to the ends of the limbs. So, at that point the tree starts dying from the ends of the limbs back causing a slow, ugly death.”

If left untreated, your maple trees can suffer severe damage from limb die-back or even death. But there is treatment. A horticultural oil as a dormant application is probably the most effective chemical treatment for gloomy scale control. However, sometimes trees are so large that thorough coverage is difficult. That’s when it is a good idea to call in the experts, like Greg. But hurry, you’ll need to treat your trees before their leaves come out this spring.

Pruning 101

Cary, NC

To Prune or Not to Prune

To prune or not to prune is a question that often comes up in gardening discussions. When is the right time of year, and just how far back should a plant be pruned? For a concept that seems fairly simple in theory, these questions leave lots of room for doubt. So how do you know what and when to prune? Here are some general rules:


Right now, we are sitting on the fence between two seasons. It’s not quite full winter anymore, yet not quite spring, either. Deciduous plants are still without their leaves, evergreens are resting, and perennials have died back to the ground. This is a good time of year to prune some plants.

For many plants, time of year really does make a difference in successful pruning. Pruning is an invigorating process that stimulates plants to put out new growth. If you stimulate growth at the wrong time of year, such as fall or early winter, a plant will be encouraged to develop new and tender branches that are easily susceptible to weather damage.  A plant expends energy to grow these branches that typically break in a windstorm and have minimal flowering and fruiting capabilities. Simply by waiting to prune until late winter or early spring, a gardener can reduce the number of tender, susceptible sprouts on a tree or shrub.

Always prune a spring-flowering shrub after it blooms. Pruning in winter would eliminate its spring blooms.

Evergreen, non-flowering shrubs can be pruned at any time, however if they are pruned in the spring they will have a chance to put out new growth and get fuller before the following winter.

Dead, Damaged, or Diseased

Dead, damaged, or diseased wood can be pruned out of plants anytime of year. It is important to remove such branches as soon as they are discovered. Dead or damaged branches become easy targets for insects and also allow for the entry of diseases. And once a disease infects a plant, it will continue to spread to healthy tissue unless removed.


With pruning, develop a less-is-more methodology. Prune only if you need to. Choose plants that reach their desired height and shape with minimal pruning.

Remove suckers at the base of trees. Also remove crossing branches from the center of small trees and shrubs back to a main branch or trunk. Branches that cross and rub across each other cause damage to plant tissue, thus allowing insects and diseases a way in.

When pruning limbs and branches, prune back to about a one-quarter inch above a bud using a slanting cut. The bud is where new growth occurs. A slanting cut will help keep the pruned area dry after a rain.

Never prune back more than one-third of a shrub. Too much pruning will shock a plant, and can cause death.

Ornamental grasses should be cut back to a few inches above the ground before they put out new growth in the spring.

Large Trees

Large trees should always be pruned by a certified arborist. Trained arborists will take care to only prune if needed, and in the correct manner. They also have all the necessary equipment and experience to prevent injury to yourself or your property.

Care Tip

Once you’ve finished pruning, it’s a good idea to use an anti-bacterial spray on your pruners before putting them away. This will help prevent bacterial diseases from spreading.

Planting for Transplant

Garden Supply Co.- Cary, NC

For those of you interested in getting a jump start on the spring growing season, now is the time to start those seedlings for transplant in the garden next month. With a little careful planning and preparation now, you can have any number of flowering annuals, herbs, and vegetables ready for planting, weeks ahead of a regular direct-sown outdoor planting schedule. And we’ll tell you how.


Plan to organize your seed packets this month to create a sowing schedule for your seeds. Look up the date of the last expected freeze in your area, and use that as a guideline for planning. You can find information on frost dates for most cities in North Carolina from the National Climatic Data Center website. Then check the instructions on the seed packets to find the number of weeks of growth required before each seedling can be transplanted to the garden outside. Count the weeks back from the last expected freeze to know when to sow your seeds.


Here’s a few tips for sowing seeds for transplant.

1. Moisten a sterile, seed-starting mixture and fill your pots or trays to within 1/4 inch of the top.

2. Sow very fine seeds with vermiculite or sand. Mix the seeds with the vermiculite or sand and pour the mix into the center of a folded piece of paper. Tap the paper gently over the medium to sow the seeds.

When sowing medium to large seeds, use the end of a pencil to create a hole in the mix. Plant seeds no deeper than recommended. Drop one or two seeds in each hole.

3. Press extremely fine seeds lightly into the medium, or water them in with a fine mist spray. Cover the seed if light is not required for germination. A thin layer of vermiculite is enough. Otherwise, leave the seed uncovered, exposed to light.

For medium to large seeds, cover seeds to a depth equal to twice their diameter.

4. Label the pot or flat with the name of the plant and the date it was planted. Read the packet and make note of the date the seed is expected to germinate so you will know when to expect sprouts to appear.

5. Spray mist the seeds to water them in. If watering from the top may disturb the seeds, place the entire container into a tub containing a few inches of water. Allow the mixture to become saturated, then set  the pots or flats aside to drain.

6. Cover the pots or trays with plastic wrap, or put them in a plastic bag secured at the top to retain moisture.

7. Unless the seeds require cool temperatures, move them to a location between 65 and 75 degrees F. in bright but indirect light. When the seeds have sprouted, expose them to bright light. Remove the plastic covering and put them under fluorescent lights. Two 40-watt fluorescent lights are a good choice and provide the quality of light required by the plants. Set the trays on your light stand and lower the lights so they’re barely touching the topmost leaves. Keep the lights on for sixteen hours each day. An automatic timer can help here. As the seedlings grow, raise the lights.


Determine the need for watering by squeezing the top 1/2 inch of medium between your fingers. If water squeezes out easily, there’s plenty of water. If the medium feels moist but water is difficult to squeeze out, add water. Just remember to water the seed flats no more than necessary.


Seedlings growing in soil-less mixtures need to be fertilized when the first true leaves appear. Feed at every other watering with a water-soluble fertilizer to promote faster growth until the plants are ready to be transplanted outdoors.

Winter/Spring Blooming Bulbs

Spring brings the welcome sight of flowering bulbs after a long and cold winter, starting with early snowdrops and crocus, then daffodils, and last but not least, tulips. Most varieties will be perennial, and many multiply in number yearly. Their successful showing next spring depends on the steps you take now in planning, planting, and care for your bulbs. So if you’re looking forward to beautiful blooms this winter and spring, here’s what you need to know.


While bulbs are commonly planted in formal beds, borders, or containers, many work well in naturalized plantings. Plan to create some naturalized areas in your landscape in the following ways:

Randomly scatter crocuses, daffodils, grape hyacinths, snowdrops, and snowflakes, and plant them where they fall. They look better when planted in clumps or drifts, so you may need to move them around a bit.

Plant spring-flowering bulbs along the edges of woodland areas or beneath the canopies of deciduous trees. Keep in mind that they should receive plenty of sunlight and finish blooming before the trees leaf out.

Insert bulbs such as crocuses in your warm-season lawn. The crocuses will brighten up the lawn and be finished blooming before it’s time to mow next spring.

Spring Blooming Bulbs from Garden Supply Co.


Now is a good time to plant spring-blooming bulbs. Remember that these bulbs require an extended cold period to bloom reliably. When bulbs don’t receive sufficient cold treatment, they produce flowers on shortened stems that are lower to the ground and often hidden by their leaves. So if you haven’t already done so, place your spring-blooming bulbs in an old refrigerator for several weeks of chill down before planting.

Follow suggested planting depths when placing your bulbs. The general rule is this: plant bulbs at a depth equal to three times the height of the bulb. Be sure to use a time-release bulb fertilizer at planting time.

*helpful hint* – some bulbs naturally resist attack by squirrels, chipmunks, and voles, but many make tasty winter-time snacks for hungry animals. We suggest dipping your bulbs in I Must Garden’s Squirrel Repellant before planting. For already established plantings, spray or dust formulas are available for surface treatment.

Care for Your bulbs

Fertilize new and established beds with a slow-release nitrogen fertilizer. Don’t wait until spring, because the bulbs are producing roots and foraging for nutrients now. Keep in mind that naturalized bulbs need to be fertilized on an annual basis to encourage perennialization.

Summer bulbs which could be killed by winter freezes should be lifted, dried, and stored. Cannas, dahlias, gladioli, caladium, and tuberous begonias should be removed after their foliage is killed by frost. Because they won’t survive the winter outdoors, they need to be cleansed of soil and stored indoors in a cool but frost-free location.

Mulch plantings with compost, pine straw, or hardwood mulch to protect tender and semi-hardy bulbs from the winter cold.

And finally, clean up and remove old, dried iris leaves, stems, and other debris to help eliminate overwintering eggs from nasty pests or iris borers.
