What to do in June

Lawn Care
•    Fertilize warm-season grasses like Bermuda, Zoysia, and St. Augustine if you haven’t already done so. (Cool season grasses such as fescue should NOT be fertilized at this time.)
•    A 1/3rd of the growth should be removed when mowing warm season grasses.
•    Core aerate your warm season yard two days after a good rain or irrigation.
•    Zoysia lawns can be started this month

Fertilizing
•    Fertilize or sidedress vegetables as needed.
•    June is the only month to fertilize centipede grass.  A ½ pound of 15-0-14 per 1,000 sq.ft is recommended however; the fertilizing needs can be better determined with a soil test.
•    Dogwoods can be fertilized at this time.  Be sure to follow the soil analysis so that you don’t over-fertilize.

Planting
•    Vegetable to be planted in June: beans, lima beans, southern peas, peppers, sweet potato, pumpkins, and tomato.
•    Brussel sprouts and collards can be planted at this time for transplanting in mid-July.
•    Trees like dogwoods can be transplanted at this time.  Use proper planting techniques when doing a transplant.  Dogwoods for example, grow best in soils which contain lots of organic matter.

Pruning
•    New growth on white pines can be pruned.
•    Outgrown hedges can be pruned.
•    Pinch off garden mums till mid-July.
•    Narrowleaf evergreens like junipers and arborvitaes can be pruned.
•    Bigleaf or florist hydrangea can be pruned when the flowers fade.
•    The dieback on hybrid rhododendrons, azaleas, and blueberries can be pruned out
•    Lastly, don’t forget to pinch your chrysanthemums to encourage branching.

Spraying 
•    Watch shrubs for the following insects: bag worms, leaf miners, aphids, spider mites, and lace bugs.  Bag worms already enclosed in their bags will need to be picked off by hand and destroyed.
•    Japanese beetles are also emerging and can be controlled.
•    Watch tomato leaves for dark spots which could be blight.  Spray with the appropriate fungicide if observed.
•    Use recommended herbicide to control poison ivy, kudzu, and honeysuckle if desired.
•    Spray the following vegetables if insects are observed: cucumber (cucumber beetle), squash (squash borers and aphids), tomato and eggplant (flea beetle), broccoli, cabbage and cauliflower (worms).
•    Continue pest control program for fruit trees and bunch grapes.  .
•    Continue with rose spraying program.

(Pesticides should be used sparingly!  Use only when needed and always follow the label)

Other Activities
•    Renovate strawberry beds after the final harvest.
•    Build a coldframe for rooting your shrub cuttings.
•    Water lawns in the early morning during dry periods.  Don’t forget watering lawns late in the evening encourages diseases.
•    Also, vegetables gardens should be watered about an inch a week.
