    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.

When daffodils don’t bloom

QUESTION: I have a lot of daffodils that shoot up nice and green, but some varieties don’t bloom as well as they once did. What do they need? Some of these have not been in the ground very long.

Daffodils 2We’re coming into prime-time for daffodils. The early varieties have bloomed and sailed gracefully through Middle Tennessee’s March cold snap. Of course you’d like to continue to enjoy as many blooms as you can.

The web site of the American Daffodil Society has a long list of reason daffodils may not bloom. See if any of these conditions may affect your flowers:

Too much shade: Daffodils should be planted in an area that gets at least a half-day of full sun, or more, if they are planted in partial sun.

Crowded conditions: After bulbs have been growing in the same place for many years, they may need to be dug up and divided. They divide themselves every year or two, and the clumps of bulbs compete for food and space. They respond by ceasing to bloom. After the foliage turns yellow later this spring, dig the bulbs, separate them, and replant them about 6 inches apart, 6 inches deep.

Fighting for food: Bulbs that are planted under evergreen trees or with other fast-growing plants may be competing against those plants for the available nutrients in the soil – and losing. The result would be weak plants and no flowers.

Impatient gardener: If you were too quick to cut down the foliage the previous year, the bulbs may not have had time to replenish themselves enough to flower. The ADS explains that daffodils replenish their bulb for about six weeks after they bloom, and the leaves should not be cut off or tied up (which blocks the sun) until they turn yellow.

In general, daffodils need well-drained, slightly acidic soil in a sunny location, and plenty of water while they are growing. They benefit from a top-dressing of 0-10-10 or 0-0-50 fertilizer, but avoid high nitrogen fertilizer, which promotes foliage growth at the expense of blooms. The right growing conditions result in a beautiful, daffodil-filled spring.
