Summer Gardening Essentials: Pruning, Disease Prevention, and Mulch Management

Summer Garden Care Priorities

Summer brings heat, humidity, and rapid growth—along with specific challenges. Proactive care keeps your landscape thriving.

Prune Without Fear

Failure to prune is the #1 landscaping mistake. If you err, it grows back like a bad haircut. Prune flowering shrubs and trees as needed; use clean, sharp tools.

Water Timing to Prevent Fungus

Water early so foliage dries before nightfall. Wet leaves overnight invite powdery mildew (white film on dogwoods, sandcherries) and Pythium blight (cottony growth on perennial ryegrass). Fungicides help, but prevention is easier.

Fire Blight on Ornamentals

Affects apples, crabapples, cotoneasters, pyracanthas. Branches turn reddish-brown, die back from tips. Prune 12+ inches below visible damage; sterilize shears in rubbing alcohol between cuts; burn infected wood.

Shotgun Fungus in Mulch

This fungus explodes, speckling siding with stubborn brown dots up to 8 feet high. Prevention: keep mulch loose and aerated—don’t just add layers annually. Fluff existing mulch every other year; it looks fresh and discourages fungal growth.

Stay observant, act early, and your summer garden will reward you with health and beauty.
