The Labor Day holiday comes at the perfect time for busy gardeners! Bearded Irises should be divided every 2 to 3 years, and Daylilies need division every 3 to 5 years. Late summer is the best time to do this, so make a morning of it and do both at once!
Bearded Iris is very easy to dig up, because the rhizome sits at soil level. Carefully dig it up, keeping as many roots as possible, and wash it off. Then check the rhizome carefully for soft areas and small holes. Remove all of these undesirable areas with a sharp knife, then divide the remaining rhizome at its natural joints (shown at right with a red arrow). Trim the foliage back to about 6 inches, and re-plant the new rhizomes.
Like everything else about Daylilies, division is very simple! Just dig up the plant, taking care to keep as many of the roots intact as possible. Then plunge two garden forks back-to-back through the center of the plant and gently pull them apart, dividing the plant in two. Repeat until you have smaller clumps. Trim the foliage back to about 12 inches and re-plant the new clumps, hilling up the soil and fanning at the roots.
Now that you have many more new Bearded Iris and Daylily plants, you might consider creating an accent planting of just these two perennials. They both appreciate sunshine and good drainage, and bloom successively, with the Daylilies often encoring to keep the Irises company! This way you can dig up and divide the entire planting every 3 years, and keep your garden growing in beauty.
Asters are full sun perennials that can provide a good bit of late-season color. The playful, daisy-like blooms in bright springy colors start popping up in late summer, keeping your garden bright right up to the first frost of winter. Asters are very easy to care for, making them a real asset in the garden.
Aster 'Alert' is a bright pink flowering New York Aster that blooms from summer to winter. It's resistant to deer, and super easy to care for. This plant blooms very densely, creating a low blanket of beautiful bright blooms.
Aster 'October Skies' is a medium-height Aster that will form a thick ground cover for your perennial sun garden. It gets it's name from the deep color of the blooms that resembles the New England sky. 'October Skies' blooms through the mid fall.
If you live in a drier part of the country, sometimes it can be
pretty difficult to plan a garden, because there are a limited number
of plants than can tolerate severe climates. Here in South Carolina the
springs and summers have been very dry for the last two years. If you
are looking to conserve water but you would still like to have a
beautiful, colorful garden, you should check out some of Wayside Gardens' drought-tolerant plants. These hardy plants will tolerate hot,
dry conditions, and you will still have a landscape overflowing with
brilliant colors, fascinating textures, and unique forms.
Watering your plants properly will also help you conserve water and
save your garden during a drought. Water deeply to ensure that your
roots grow deep into the ground – light waterings lead to shallow roots
which tend to lose moisture to evaporation during dry spells. Also try
to skip a few days between waterings unless your plant is in danger of
scorching – this time will force your plants to seek moisture deeper
under the ground, promoting strong root growth.
This is one of my favorite images from our catalogs and websites. It is Coreopsis ‘Snowberry,’ and it’s an amazing perennial that will tirelessly produce mounds of these arresting soft, creamy blooms, lending a real touch of elegance to your sunny garden throughout the entire summer. Even better, the foliage is evergreen, so it is attractive even when it isn’t in bloom. ‘Snowberry’ is a sterile sport of C. ‘Nana,’ so it won’t invest energy into seed production rather than making more flowers. This allows it to rebloom more quickly than many other Coreopsis, especially if you deadhead it regularly.
Having a garden full of colorful blooms that last from first frost to last is just a matter of carefully planning and selecting the right plants. Planning an all-summer colorful garden will help you avoid the extra work in the heat, and have a successful garden right until winter.
There are plenty of beautiful varieties that will bloom very late and keep your garden beautiful well into the fall, including Salvia, Lobelia, Echinacea, and etc. Take a look at the full line of Fall Blooming and Summer Blooming Perennials from Wayside Gardens.
As late summer approaches, we tend to hide from the heat and let our gardens wait until fall, when it cools down and we can prep for the next spring. Fortunately, there are some wonderful plants that may be able to thwart that late-summer lull in gardening fervor.
Heat Tolerant Perennials
It’s getting hotter, and unfortunately there may be a few long periods without rain. There are a few plants that are perfect for those arid spells. These wonderful late-summer plants will bloom right through the hot months of July and August.
Many Echinaceas will tolerate a hot dry climate. These hardy coneflowers will bring brilliant color to your garden, and they are resistant to heat and will tolerate dryer soil. Salvia is another late summer bloomer that will resist the heat. Salvia comes in enough colorful varieties to ensure your garden will stay impressive even as the the temperature rises and the summer showers begin to wane.Also look at varieties of Clematis and Hemerocallis which are also both excellent hot weather plants. For foliage interest you could try one of the easy to grow heuchera varieties which have brilliant colors and great texture throughout the hot summer into the fall.
