    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

I covered my daffodils in the fall with a heavy layer of pine straw. The leaves have come up but they are not budding or blooming. Is the pine straw too acidic for these plants?

Daffodil copyAfter a long winter, we look forward to the daffodils blooming in spring, and it’s a disappointment when they don’t produce the flowers we expect.

The failure to bloom is not due to pine straw causing acid soil; daffodils – or jonquils, as we sometimes call them — tolerate a range of soil types, as long as it is well-drained and moderately fertile, and some varieties actually prefer slightly acid soil. A lot of garden experts suggest mulching daffodil beds with a light layer of pine straw. Small, early blooming daffodils may not be able to penetrate a thick layer of mulch.

So consider some of the other possible reasons daffodils don’t bloom:

Were they cut down too quickly last spring? After daffodils finish blooming, allow the foliage to remain until it turns yellow. This allows the bulb to gather and store energy for growing and blooming the following spring.

Were they given a high-nitrogen fertilizer? Nitrogen tends to grow a lot of foliage at the expense of flowers. Fertilizer that contains a higher level of phosphorous promotes blooming.

Is the bed too crowded? Bulbs continue to grow and divide underground, and after several years, the bulbs may grow big, lush clumps with few or no blooms. If it’s an old, established bed, it may need to be thinned. Dig the bulbs, separate and replant them.

Too little sun? Daffodils need six to eight hours of sunlight to bloom well. They tolerate dappled shade in early spring, but if they are in dense shade, they likely will not bloom.

These are among the most common causes. The American Daffodil Society has a whole page of reasons that daffodils fail to bloom, which you can read here.

For gardeners in Middle Tennessee (where The Garden Bench calls home), this is a good time to mention that the Middle Tennessee Daffodil Society is holding its annual Daffodil Show March 19 and 20 at Cheekwood Botanical Garden. This is the time to see some of the most perfect daffodils grown and arranged by serious daffodil aficionados. To learn more, visit the MTDS site here.
