• Sow lettuce seeds now for a fall crop. Set out broccoli and cabbage plants too.

• Wisteria trees need to be trimmed throughout the summer. Keep long tendrils trimmed back to maintain the shape of the tree.

• Feed fuchsias, begonias, summer annuals, hanging baskets and container plants to keep them green and blooming right up until frost.

• When lily flowers fade, remove the flowers but don’t cut back the stems until leaves have yellowed in the fall.

• Plant beets now for fall harvest. They will have a deeper red color than beets planted for spring harvest, and tend to have higher sugar levels too.

Summer Fruit Tree Care

Summer is the time when fruit trees grace us with their abundance of sweet, juicy fruit. It is also the time when fruit trees need your care and attention. This year may not be a very good fruit season, but you need to keep your trees healthy and strong so they will produce well for you in years to come.

Young fruit trees need particular attention. The most important cultural practice during the first year is watering. No other single element of plant care causes more problems or failures than over or under-watering. Water supply must be consistent. Drought followed by flooding can cause trees to stop growing due to the shock of these extremes conditions.

Check the soil weekly. A new tree needs approximately 10 gallons a week during the hot summer months. A tree two years old may need 20 gallons a week. A mature fruit tree can use 50 gallons a week or more. Fruit trees need water to size up their fruit properly. It’s best to water deeply and infrequently rather than shallowly and frequently. Water trees on clay soils, water every 2 to 3 weeks. For young trees, make a moat around the base of the tree so the water stays in the root zone. On older trees, water at the drip line of the tree.

Keep the base of your fruit trees weed free. Spread a 2- to 3-inch thick layer of organic mulch, such as pine straw or bark mulch, over the root zone but keep it a few inches away from the trunk. Organic mulch also breaks down gradually, providing organic matter to the soil.

Inspect your fruit tree bark, branches, leaves, and developing fruits often. Look for signs of insects and diseases and apply the appropriate organic controls. It’s usually easier to control pests if you act before or just as they are getting established, than to control them after they have caused lots of damage.

Paint trunks of young trees with white latex paint or Tree Trunk White to prevent sunburn which causes the bark to crack. This leaves openings for boring insects to enter. They can cause serious damage and even death in young trees.

While most pruning of fruit trees is done in the late winter, some can be done in the summer as well. Summer pruning can eliminate any dead, diseased, or broken branches. prune off any new branches that are growing from the base of the tree (suckers) or straight up from horizontal branches (water sprouts).

Keep your fruit trees healthy and they will give you many years of abundant harvests.

• Mother’s Day is the perfect time to give a living plant as a gift. Rhododendrons, lilacs, hanging fuchsias and ivy geraniums are sure to please her.

• Beautiful African Violets will decorate your indoor spaces with their masses of flowers in all shades of purple, blue and pink.

• Flower seeds can be sown directly in the garden now. Cosmos, nasturtiums, marigolds and zinnias will give you beautiful flowers all summer.

• Plant an herb garden in a container near the kitchen door for convenient fresh spices like basil, oregano, parsley and thyme.

• When you plant your vegetable garden, why not grow a little extra to donate to the food bank this summer.

Clematis: Queen of the Vines

Clematis are the aristocrats of the flowering vines. With over 300 species and many hybrids, this group of mostly woody, climbing vines has a lot to offer the gardener.

Their flowers span the color spectrum. The large-flowered cultivars range in color from rich reds, purples, and blues to pale pink and white. The smaller flowered “montana” varieties cover themselves with masses of pink or white fragrant blooms early in the season. And the evergreen clematis, with its profusion of starry-white blooms, carries a heavy fragrance.

There is a clematis to enhance any garden, no matter how large or small. Some varieties, if left to wander, will easily grow to 30 feet, while others mature at 6 to 8 feet. Many hybrid varieties mature at 8 to 12 feet, and are stunning on a fan trellis.

Clematis do not climb by tendrils, but instead by gently twining their leaf petioles around nearby supports, including plant stems, branches, wires, small poles and themselves. They do not cling to walls and, without support, will ramble until they find something suitable to climb on. In the wild, clematis are often found growing at the woods’ edge, where their tops can reach full sun and their roots remain in the shade.

Selecting the right place for clematis is important for its success. Clematis thrive where the vines receive sun for at least six hours a day with cool, moist soil for the roots. Morning sun is preferable. Plant vines in the shade of a small shrub or plant a groundcover or perennial over the root area to shade the soil.

Clematis can be planted deep and actually benefit from having the crown buried up to four inches below the surface of the soil. This helps the plant recover from dormant buds below the soil, if the top of the plant is damaged.

Begin feeding clematis in early spring, as soon as the new shoots start to grow. A generous mulch of garden compost mixed with well-rotted manure and a handful of bone meal is a good recipe. You can substitute a general purpose fertilizer for the manure if you prefer.

Keep the mulch away from the stems. During the summer months, fertilize with a liquid fertilizer twice a month until mid-August. After that, the plants need time to slow down and harden off for the winter.

Pruning clematis vines is somewhat complicated. Keep track of the names of the varieties you plant so that you can ask for help at your local nursery. Proper pruning will create masses of flowers that cover the plants at bloom time. Improper pruning will delay flowering, and no pruning will leave you with a tangled mass of stems but plenty of flowers.

The first spring after planting, all clematis should be cut back just as you see leaf buds developing. Cut above two sets of buds on each stem. This will thicken the stems and encourage proper root development.

Clematis will reward you with an abundance of beautiful blossoms for many years. To see a clematis in full bloom is to understand why it is often called “the queen of the flowering vines”.
