What to Do in June

For more details on the following, call your local Extension office or visit the University of Florida’s publication website: http://edis.ifas.ufl.edu 

Fertilize citrus trees if not done in May. (See January)

Plant and fertilize annuals. (See January)

Spray roses to control black spot. (See March)

Watch for lacebug infestations. (See March)

Fertilize outdoor potted plants. (See April)

Inspect lawns for insect pests. (See April)

“Solarize” the vegetable garden or plant a cover crop. Nematodes and other soil pests can be managed by using the sun’s heat to sterilize garden soil. Clean all plants and debris from garden soil. Moisten thoroughly and cover the garden with clear plastic (2-6 mil). Leave plastic in place for a minimum of four to six weeks. Nematode populations can be reduced by planting a cover crop of French marigolds, hairy indigo, or Southern peas.

Give your houseplants a vacation. Move houseplants into the shade of a tree where they will benefit from strong filtered light, summer weather and rainfall. Provide a slow-release fertilizer.

Correct palm and cycad deficiencies. Queen palm, paurotis palm, and king sago frequently develop manganese deficiencies. Look for yellow, brown, or distorted growth on new leaves. Foliar sprays of manganese sulfate (not to be confused with magnesium sulfate) at a rate of 1 teaspoon per gallon along with one pound of manganese sulfate applied to soil will correct this deficiency on the next flush of growth.

Start cuttings. Take 4 to 6 inch cuttings of tip growth. Remove lower leaves. Dip cut ends in rooting hormone and stick cuttings in a sterile, moist soil mix. Cover soil and cuttings with a clear plastic bag. Place in strong, indirect light.

Establish plants during the rainy season. June through September are usually rainy months. New plants require frequent irrigation to get established, but you can reduce work and water by taking advantage of rainfall.

Tune up your irrigation system.

Irrigate according to the needs of plants. Lawn grasses and vegetables may need 1/2 to 3/4 inch of water twice a week. Water the lawn when 30 to 50% of the lawn shows signs of wilt (blue-gray color, folded blades). Place a few shallow cans or glasses in the irrigated zones and measure how much your sprinklers apply. Adjust your timer schedule accordingly. Landscape and fruiting plants will suffice with 1 inch of water per week. A rain shut-off device will override an automatic irrigation system in the event of rain.

Prune. Prune lightly to shape plants and encourages branching. Never remove more than 1/3 of a plant's foliage at a time. Summer flowering plants like hibiscus, oleander and crape myrtle will produce more blooms if old blossoms and seed pods are removed.

Plant palm trees. Palm roots grow when the soil is moist and warm so summer is best for planting palms. Plant top of root ball flush with the surrounding soil. Apply a 3 to 4 inch mulch. Never allow the soil to dry out during the first several months. Tall palms should be staked.

Mow lawn frequently. Mow often enough so that no more than 1/3 of the blade height is removed per mowing. Leave clippings on the lawn to recycle nutrients, or use collected clippings as mulch or compost material.
