    It’s time to plant those tender herbs and vegetable transplants, such as basil, dill, tomatoes, green peppers, hot peppers, eggplant.

    If tomato transplants are already too tall and leggy, you can plant them on their sides and cover the long stems with soil. The stem tips will turn upward, and the buried stems will sprout roots.

    Sow seeds of bush beans and pole beans, cucumbers, sweet corn, melons, okra, field peas, pumpkin, squash and zucchini. Follow the directions on the seed package for planting depth and spacing. Vegetables grow best in full sun.

    Cut the faded blossoms of peonies. Fertilize the plants lightly in late spring or early summer.

    Remember the basics of watering: morning is best, so plants’ leaves have time to dry before evening. Lawns, perennial borders and annuals like to have 1 – 1½ inches of water per week.

    Many indoor plants enjoy a summer vacation outdoors. Give them a cool, shady spot in the yard, and don’t forget to water them.

    Prune thyme frequently so it will stay full and green in the center.

    Weeding is easiest after a rain. If the ground is too dry and you need to weed, soak the bed first with a hose or sprinkler.

    Whether they’re growing in the ground or in pots on the porch, pinch the tips of geraniums from time to time to encourage them to branch out and to produce more flowers. Geraniums in pots benefit from regular feeding with a water-soluble fertilizer.

    Remember that mulch can be a gardener’s best friend. Pine straw or composted leaves are good alternatives to hardwood mulch.

    Harvest herbs as they reach their peak. Dry small leaves on a screen, hang small bunches of long-stemmed herbs in a warm, dry room out of the sunlight.

    Plants growing outdoors in containers dry out quickly when it’s hot. Check them daily, and water as needed.

    Don’t go near hydrangeas with the pruning shears unless all you’re cutting is dead branches. If the bigleaf hydrangeas look like they’re not going to bloom, it could be that the buds were nipped in a late cold snap, or the plant was pruned too late last year.

    As the flowers of Shasta daisies begin to open and then to fade, keep them clipped off. This prolongs the blooming season of daisies (and most other annuals and perennials), and keeps the plants looking better, as well.

    Watch for aphids on shrubs and perennials. A strong blast of water from a hose will remove many of them, or spray with insecticidal soap.

Plant perennials now, enjoy them later

I’m still seeing perennials for sale at garden centers. Some of them are being sold at reduced prices. Can they really be planted this time of year?

Daylilies are among the perennials that can be planted now.

Daylilies are among the perennials that can be planted now.

Spring is the typical planting time, but for gardeners who are willing to be patient or take a chance on a plant that may look like it’s past its prime, early fall is a good time to plant. Many of the plants on sale still have plenty of life, even though they don’t look their best right now.

But if you make careful choices and plant now, they will begin to establish good root systems and should spring back beautifully in the garden next year.

While perennials you find now may not be at the peak of perfection, you should still look for healthy plants with no sign of disease. Here are guidelines from the website of Clemson University’s Cooperative Extension and other sources:

  • Look for plants with good color and vigorous appearance. Avoid plants that show any sign of disease.
  • Ease the plant out of the pot and look at the roots look healthy, and not mushy or limp. Avoid anything with roots that have a bad odor.
  • Buy labeled plants (unless you want to be surprised!) and label it in the garden so that you can remember where and what you planted next spring.
  • In the garden, prepare the soil and amend it as needed with compost. Dig a hole a few inches wider that the plant’s pot, remove the plant from the pot and gently loosen the roots, then set the plant in the ground with the base of the plant level with the surrounding soil. Fill the hole with soil, water thoroughly, and add mulch.
  • Don’t set them out and forget them. October can be a dry month, so remember to provide water on a regular basis.
