    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.

Shrubs for a good foundation

Question: I plan to replant the bed at the front foundation of the house with new shrubs. I will need about 5 shrubs, evergreen and low maintenance. The front of our house gets morning sun and afternoon shade. What type of shrubs can you suggest?

boxwood shrubs

Boxwoods are a favorite choice of shrubs for foundation plantings.

I talked with Mark Kerske at Gardens of Babylon garden center in Nashville, and he has several good recommendations:

Boxwood is a tried-and-true choice. “It’s one of my favorite plants,” Kerske says. Boxwoods can grow quite large over time, but there are smaller varieties available that grow to more suitable size for foundation plantings. They take full sun but also do well with some shade.

Cryptomeria is a fast-growing conifer with dark green needles that can grow very tall and wide, but there are dwarf varieties (‘Lobii Nana’ and ‘Pygmaea’ are two that are mentioned in the Southern Living Garden Book) that grow only to about 3 – 4 feet tall.

The cherry laurel ‘Otto Luyken’ is also a favorite. It’s a compact shrub with deep green, glossy leaves that grows to about 4 feet tall and 4 to 6 feet wide.

Whichever shrubs you choose, good soil preparation will ensure that they get off to a good start. Work good compost into the soil to improve the drainage, and use mulch in the planting bed after you plant the shrubs to keep the soil moisture consistent. “You don’t want to keep the soil wet, but just moist,” Kerske says. “That’s the key, maintaining constant moisture.”
