July Gardening Tips

  • Prune climbing roses and rambler roses after blooming if the plants are two years or older
  • Do not fertilize trees & shrubs after July 4th. Fertilizing late may cause lush growth that is susceptible to winter kill
  • Bearded irises can be divided now if needed (most should be divided every 3-5 years)
  • Don't pinch back mums after mid-July or you may delay flowering
  • Sweet corn is ripe when the silks turn brown
  • Dig up potatoes when the foliage dies down. Plant fall potatoes by mid-July
  • Cucurbits. tomatoes, and peppers may have pollination issues this month. Tomatoes and peppers cannot set fruit when daytime temperatures exceed 90oF. During high humidity, cucurbit pollen becomes sticky and does not transfer well
  • Squash vine borer damage may start showing this month
  • Water lawns frequently enough to prevent wilting. Early morning irrigation allows the turf to dry before nightfall, reducing the chance of disease
