June Gardening Tips

June Garden Calendar

Watch for adult Japanese beetles on plants such as crape myrtles, roses, grapes, linden, crabapples, chaste tree, Japanese Kerria, and many others.  Control by knocking beetles into a jar of soapy water, or spray with Sevin, Neem Py, Bug Blaster or Insecticidal Soap. To control Japanese beetles in the grub stage, apply Milky Spore or Hy Yield Kill a Grub (containing granular Merit) to lawns for control up to 20 years. 

For easy watering of many plants at one time, use a soaker hose for 2 hours every 7-10 days when soil is dry.  

Watch for hatching bagworms, especially on evergreens such as junipers and arborvitae. Handpick bagworms and destroy them, or spray with Thuricide (Bacillus thuringiensis) or Fertilome Borer, Bagworm, Leafminer, & Tent Caterpillar Spray.  

Prune azaleas, viburnums, forsythias, lilacs, and other spring blooming shrubs after blooming.  

Plant perennials throughout the month for summer flowering.  Use Bone & Bloodmeal and Compost & Manure mixed with the soil when planting.  Trim back the flower stalks of perennials which have finished blooming.

Treat water gardens with AquaClearer or Green Clean natural bacteria to control green water and sludge buildup.  Use oxygenators (submerged water plants) as a natural filter to help control algae buildup.  They provide oxygen for fish and will help balance the natural ecosystem of a water garden making the water clear naturally.


If you are having trouble with Zoysia or Bermuda grass in your landscape bed, now is the time to apply Turflon Ester to those pest grasses to keep them out.
