  • Cut back tired annuals and rejuvenate with water-soluble fertilizer.

  • Weed, water, and fertilize as needed.

  • Deadhead to promote extended flowering.

  • Watch for signs of pests and diseases, especially spider mites.

  • Cut flowers early in the morning for longer-lasting arrangements.

Vegetables and Herbs

  • Harvest crops as they mature; pick herbs before they flower for best flavor.  Use or preserve right after harvest for best nutrition and taste.

  • Water as-needed and mulch the soil.

  • Watch for beetles and disease.

  • Pull and compost weeds.

Patio and Container Plants

  • Monitor plants daily for water needs and pest control.

  • Apply water-soluble fertilizer as needed for healthy vigor- usually every 2 to 4 weeks.

  • Pinch back straggly plants and deadhead spent blooms to maintain neat appearance.

  • Replace tired or stressed summer annuals with fall bloomers such as mums.

Tree and Shrubs

  • Avoid pruning or fertilizing spring- blooming shrubs; it may cause tender new growth to be subject to winter damage.

  • Water as-needed.


  • Even if plants are still flowering, don’t fertilize after the first week of the month; it may encourage tender new growth to be  subject to winter burn.

  • Continue deadheading spent blooms.

  • Spray diluted fungicides as needed.

  • Water weekly during hot weather; water roots and not the foliage.


  • Harvest fruits as close to fully ripe as possible.  Eat or preserve right away.

  • If birds or other pests are damaging ripe fruit, pick earlier when blossom end turns pink and allow fruit to ripen indoors.  Never refrigerate; an air-conditioned house, however, is ideal.

  • Early varieties will finish producing this month.  Compost fruitless plants.  Later plantings will start ripening at the end of this month for another harvest.

  • Check for blossom-end rot and remove infected fruits.  Prevent blossom-end rot by maintaining even soil moisture.

Perennials and Bulbs

  • Deep watering is essential this month.

  • Weed and fertilize as needed.

  • Deadhead to promote plant vigor.

  • Cut back unsightly perennial foliage.

  • Watch for signs of pests and diseases.


  • Maintain mowing and watering schedule.  raise mower blade one-half inch.

  • Assess lawn condition for possible fall renovation.

  • Watch for signs of insect damage and fungus diseases; apply chemical controls as needed.
