    Tips & tasks – August

    Water lawns and garden beds early in the morning to allow foliage plenty of time to dry before nightfall.

    Container gardens will benefit from a light application of all-purpose fertilizer.

    If petunias have grown long and shaggy, cut them back and give them a dose of fertilizer. They should bloom again quickly.

    If squirrels and birds go after your ripe tomatoes, pick them while they are still green and allow them to turn red indoors. For best quality, don’t store fresh tomatoes in the refrigerator.

    Make sure spring-planted trees and shrubs get plenty of water during hot weather.

    Keep cutting the spent flowers of annuals so they will continue to bloom into the fall.

    To conserve soil moisture during hot weather, replenish mulch in annual and perennial beds as necessary.

    Begin planning a fall garden. Spinach, lettuces, radishes and other fall crops will mature when the weather turns cool.

    Begin clean-up of summer vegetable beds. Remove any decayed or dying foliage to prevent diseases from taking hold.

Leafrollers make a meal of cannas

My cannas were growing well and I thought should be about to bloom when I noticed that the leaves hadn’t opened, and they looked like they’d been stitched together! When I unrolled the leaves, I found a little grub and some other black substance. What is that? What can I do about it?

Your cannas have become host to a fairly common creature throughout the southeast called a canna leafroller, and it can do quite a bit of ugly damage to this summer-flowering favorite.

The grub you see when you unroll the leaves is the larval stage of a little brown moth. Continue reading

Queen Anne’s Lace in an early-summer garden

I like to see Queen Anne’s Lace growing along the roadsides in summer. How can I get it to grow in my garden?

It’s not hard to get Queen Anne’s Lace started in a garden bed. In fact, the reason you see so much of it in open meadows along the side of the road is that it’s a prolific self-seeder.

After they bloom in late spring and early summer, the lacy clusters of white flowers fold up into a cup-shaped clump of seeds. Continue reading

Cut flowers to bring summer indoors

With summer in full bloom, those daisies and black-eyed Susans, zinnias and sunflowers, coneflowers, dahlias and others make beautiful bouquets to enjoy indoors. To make those bouquets last longer, it’s best to start early.

“I definitely always cut before the heat of the day sets in,” says Tallahassee May, owner of Turnbull Creek Organic Farm in Bon Aqua, Tenn. “This is better than in the evening, when the flowers still seem to hold heat from the day, even after the sun has set.”

The secret to long-lasting bouquets from the garden, May says, is to keep things clean. Continue reading

Keep zinnias free of powdery mildew

QUESTION: I love zinnias and plant them every year. Sometimes they do well and look great all summer, but many years the leaves are covered in powdery mildew. How do you get rid of this problem?

Powdery mildew is a fungus that appears as gray or white splotches on leaves, stems and flowers of zinnias and other ornamentals and some vegetable plants. It travels by airborne spores, and thrives when nights are moderately cool and foliage stays damp. A mild covering of powdery mildew is merely unattractive, but a severe case can cause distorted shoots and leaves, misshapen flowers, or can prevent flowering altogether. Continue reading

Transplanting roses in the ‘wrong’ season

We are moving from one home to another this summer. We have a rose bush in our garden that was a gift for a special occasion that we planted about three years ago, and we’d like to take it with us. Is it possible to transplant a rose bush? It’s not very large, but it has a few blooms on it now.

Rose

The best times to transplant roses are in early spring or in the fall, but if, for whatever reason, mid-summer is when you have to do it, then give it the best care possible. Here is advice from Marty Reich, a consulting rosarian with the Nashville Rose Society and American Rose Society: Continue reading

Move irises to a new home

I have irises that will need to be moved. They have been in a very shaded spot and have never bloomed for 4 years. I am moving to a new house and would like to transplant them. I know now is not the time to transplant, but should I trim the leaves back or leave the leaves?

Irises bloom best in full sun.

Now is not a bad time to move the irises. The experts at the American Iris Society and other sources suggest mid- to late-summer as the best time for digging, dividing and moving irises, but since yours haven’t bloomed in four years, they should be happy whenever you’re able to give them a new, sunnier spot in your new home’s landscape.

Here’s the method suggested by gardening experts: Cut the leaves in a fan shape about 6 inches tall, then lift the clump or rhizomes with a spading fork, wash off the dirt, and inspect the rhizome for soft spots, damage or disease. Continue reading

Dig daffodils, save the bulbs

The daffodil bed needed thinning, so I dug them out after the leaves started turning yellow and replanted many of them in the same place. Now I have dozens of extra bulbs I can share with friends. Do they need to be planted right away?

spring-flowering bulbsWhen a daffodil bed begins to look crowded and you begin to see fewer flowers, it’s a sure sign that the bulbs need to be thinned out. One bulb becomes a clump of bulbs after a few years. The American Daffodil Society suggests digging and dividing daffodils about every 4 – 5 years.

The ADS notes that the time to do this job in many regions is now – after blooming ends and the foliage turns yellow. To save bulbs for later planting, wash them thoroughly and let them dry completely, at least a week, and put them in mesh bags, onion sacks or pantyhose and hang them in the coolest place you can find, a place with good air circulation to minimize storage rot.
Store them until the time is right to plant them in the fall.

To learn more about daffodils, visit the American Daffodil Society website, where you can also find links to regional daffodil societies in different parts of the country. In Nashville and Middle Tennessee (where The Garden Bench calls home), the Middle Tennessee Daffodil Society is the group for daffodil enthusiasts. MTDS will host the 2018 American Daffodil Convention and Show, April 5 – 8 in Franklin, TN. Visit the MTDS website here.
