June Gardening Tips

  • Watch for bagworms (Thyridopteryx ephemeraeformis) feeding on plants, especially juniper and arborvitae. Collect and dispose as they are located. 
     
  • Trees and shrubs may still be fertilized as needed before July 4th. 
     
  • Japanese beetles (Popillia japonica) are usually active at this time. Hand-collect adults early in the morning and deposit them in soapy water. 
     
  • Aster yellow may start showing symptoms this month. Nothing can be done to save infected plants, so remove and discard any infected plants. 
     
  • Dethatch zoyzia lawns as new growth begins to keep the lawn vigorous and reduce disease problems. Cool-season lawns should not receive fertilizer until fall. 
     
  • Thin overloaded fruit trees to receive larger and healthier fruits come harvest time. Thinned fruits should be a hands-width apart. 
     
  • Warm-season vegetables that can still be planted through June include basil, beans, cucumbers, edamame, eggplants, melons, okra, peppers, summer squash, sweet potatoes, and tomatoes.
