    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.

Mealybugs make a meal of houseplants

One of my jade plants has some sort of white fluff on the stems. Is this normal?

Jade plant

Jade plant is one of many houseplants that can be affected by mealybugs.

White fluff is not normal. Your jade plant is no doubt hosting an infestation of mealybugs, tiny sap-sucking insects that will damage the plants if they are left to multiply. They appear as small, cottony growths on the stems and leaves of jade plants and many other houseplants. They do their damage by inserting their piercing mouthparts into the plant’s tissue and extracting the juices.

Mealybugs thrive in a warm, dry environment – such as inside a home in winter. Female mealybugs don’t fly, but once established on a plant, they can find their way to nearby houseplants so it’s good to get rid of them as quickly as you can – not always an easy task, because that fluff is rather waxy and resistant to pesticides.

The best way to begin to eradicate the insects is to remove them by hand. Dip a cotton swab in rubbing alcohol and wipe them off. You may have to do this two or three times until all the unseen eggs that may have been deposited have hatched. If the infestation is heavier, follow up with a spray of insecticidal soap.

Always be watchful for insects to reappear, and try to get rid of them quickly. In addition to jade plants, mealybugs may find their way onto African violets, ferns, pothos, Norfolk Island pine, schefflera, diffenbachia, pothos, philodendron and many other popular houseplants.

Mealybugs are a common problem, and information is readily available. The North Carolina State University Cooperative Extension provides information here.
