    GARDEN EVENTS IN MIDDLE TENNESSEE

    May 20: Master Gardeners of Davidson County Urban Gardening Festival, 9 a.m. - 4 p.m., Ellington Agricultural Center Demonstration Garden. Free admission. www.mgofdc.org; on Facebook at www.facebook.com/mgofdc.

    June 10: Middle Tennessee Daylily Society show and sale, Ellington Agricultural Center’s Ed Jones Auditorium, 440 Hogan Rd. in Nashville. Sale open at 10 a.m.; show opens to the public at 1 p.m. To learn more about the Middle Tennessee Daylily Society, visit www.middletndaylilysociety.org.

    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.

Grow the best blueberry bushes

QUESTION: I have had blueberry bushes for 2 years and they still look awful. I’ve been told to put coffee grounds around them but they don’t grow or produce fruit.  We have them in a bed with some calla lilies which are doing very well. The plants were healthy plants from the co-op.  I have a friend in Clarksville that has lush bushes with lots of fruit.  I asked if they did anything special and she said “no”.  Any tips to help us would be appreciated. — Karen in Donelson

Blueberries need sun, water and the proper soil pH to produce a good crop.

Blueberries are pretty finicky about what they need to grow well and produce, so I’ll let you know what those needs are, and you can decide if they’re getting what they require.

Do you know what the variety of your plants? Different types are adapted for different regions, and in Middle Tennessee, the varieties called rabbiteye and southern highbush blueberries are the most reliable choices.

Furthermore, they are not always self-fertile, which means you need more than one variety for cross-pollination to take place (and the insects buzzing around to pollinate them at the right time).

Now, the soil. Blueberries require acid soil, with a pH level of 4.5 to 5.6, so if you don’t have that information, have the soil tested. Coffee grounds are acidic, and that’s why the addition of coffee grounds may have been suggested. The fact that the calla lilies are doing well suggests that the pH might be part of the problem; they grow better in soil that is more alkaline. Blueberries also require soil that is well-drained, so make sure they’re planted in a place that doesn’t stay wet.

They need full sun, and they don’t like to compete with grass and weeds, so mulch around them with shredded bark or compost to keep weeds under control. They also suffer during times of drought because of their shallow roots, so make sure they get sufficient water (about once a week in dry weather, suggests garden expert Felder Rushing in his book, Guide to Tennessee Vegetable Gardening).

Blueberry bushes benefit from the same type of fertilizer as azaleas (which also need acid soil to grow well). Apply fertilizer, following label directions, in the spring.

Your friend who has lush bushes and lots of fruit may not be doing anything special, but it sounds like her plants are the right type for the area, in soil they like, and are getting plenty of sun and enough water. With a little more care and attention, yours may also re-gain their health.

  1. I replaced my boxwood hedges this year with blueberries. My husband suggested mulching with peat moss, which I’ve done, and seems to be working (peat moss is higher acid). My mother also advised me to remove all blossoms this year and next year if I could do it, so the plants will put that energy into developing roots versus fruit. Thus far, they are looking good and growing well. I’ve also watered them for an hour or so weekly with a soaker hose when it’s dry (which has been a lot this year).
