Chores and Maintenance

• If rain is lacking, practice water-wise horticultural techniques
• Determine which plants are most important, and water them first
• Water plants early in the day through drip irrigation or hand-held hose with shut-off nozzle
• Re-apply mulch to plantings to help conserve moisture
• Allow lawns to go dormant; they will green up again when rain returns
• Continue to remove weeds that compete for water
• Continue to stake floppy plants and vines
• Mow lawns regularly to keep grass height at 2-2½"
• Continue to aerate and moisten compost pile to speed decomposition
• Continue to apply acid mulch to azaleas, rhododendrons, and other ericaceous ornamentals
• Apply a summer mulch to rose beds to preserve moisture and control weeds
• Deadhead annuals and perennials to encourage continuous bloom, and cut back any rampant growth
• Continue to spray roses weekly with a baking soda fungicide (See June Tips for recipe)
• Remove any fallen leaves and debris that can harbor insect pests and disease organisms
• Pinch back asters and chrysanthemums one last time
• Finish deadheading rhododendrons and lilacs
• Continue to apply deer repellent

• Continue to re-pot any houseplants as needed
• Continue to lift, divide, and propagate spring-flowering perennials
• Sow seed of lettuce, kale, broccoli, cabbage, radishes, and arugula for fall harvest
• Sow seed of English daisy, forget-me-not, and pansy now
• Continue to propagate shrubs from softwood cuttings
• Propagate spring-flowering perennials
• Propagate herbs from cuttings
• Continue transplanting container grown plants

Pruning/Fertilizing

• Deadhead hybrid tea, grandiflora, floribunda, miniature, repeat-blooming shrub, and climbing roses
