    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.

Lemon verbena likes warmer winters

Last year I planted lemon verbena in a new herb garden because I loved the fragrance. I thought it was a perennial, but it seems to have died over the winter. Will it come back this year?

LemoLemon verbenan verbena (Aloysia citriodora) is a tender perennial, which means it may survive a mild winter in some areas, but it will succumb to extended periods of below-freezing days and nights. The Herb Society of America notes that this herb is marginally hardy in Zone 8 – that’s where extreme minimum temperatures might be about 20 degrees, so you can see that it prefers warmer climates. It is native to Argentina, according to the HSA.

Even so, it’s worth adding to the garden for its delicate lemon fragrance and its culinary uses. Fresh leaves add a lemony flavor to sweet and savory dishes – sauces and marinades, ice creams, custards, tarts, frostings and fruit salads. It can also be dried, makes a nice tea by itself or combined with other herbs, and adds a fresh fragrance to sachets and potpourris.

Plant it in full sun in fertile soil. In the ground, lemon verbena will likely grow in a season to a lemony-sweet smelling 3-foot tall plant with woody stems. It flowers in late summer to early fall.

As the weather warms, depending on the microclimate in your garden, you may find that it had died down to the ground but may send up fresh shoots from the roots. You can also grow lemon verbena in a container, and keep it in a sunny, south-facing window or under plant lights in winter.

Harvest the leaves after the plant is at least eight inches tall. To dry the leaves, hang the branches in a well-ventilated location out of the sun until the leaves are crisp, then strip the leaves from the stem and store them in a tightly sealed container.
