Planting
___ Generally, the month of June is too hot to plant. However, if you must, keep new plantings well watered.
___ Continue to plant warm-season grasses.
___ Transplants of eggplants, peppers, and tomatoes may be planted this month.
___ Plant seeds for fall transplants.
Care
___ Deal with excessive thatch in lawns.
___ Remove fallen/diseased leaves from and around roses.
___ Use mulch around vegetables.
Watering
___ Most annuals and plantings in pots will need to be watered on an almost daily schedule.
___ Water lawns and trees to a depth of 1 inch when needed.
___ Water vegetables to a depth of 1-2 inches per week.
Problems
___ June weather brings problems with insects and diseases. Make sure to monitor all plantings on a regular basis for signs of trouble such as wilting, browning or yellowing, holes, and leaf curling.
___ Be on the watch for spider mites. They are almost too small to be seen with the naked eye, but fine webbing is a sign of heavy infestation.
___ Be cautious about using weed killers on lawns. High temperatures may cause damage after using pesticides.
Pruning
___ Prune roses that are not repeat bloomers.
