1. PlantingA vareity of fresh-picked peppers, herbs and tomatoes on a table.

  • Warm-Season Vegetables: Plant tomatoes, peppers, melons, okra, and cucumbers for a summer harvest.
  • Succession Planting: Sow another round of bush beans, carrots, and beets for staggered harvesting.
  • Pumpkins: Mid-June is the perfect time to plant pumpkin seeds for a fall harvest.
  • Summer Annuals: Add heat-loving color like vinca, zinnias, marigolds, and portulaca to garden beds and containers.
  • Pollinator Plants: Add a patch of bee- and butterfly-friendly flowers or set up a bee bath to support local pollinators.
  • Plan Ahead: Start planning fall veggie crops like Brussels sprouts and broccoli; sow seeds indoors or under protection.

2. Pruning

  • Spring-Flowering Shrubs: Lightly prune shrubs like lilac and weigela after blooming to shape and tidy them.
  • Roses and Annuals: Deadhead roses and spent blooms mid-June to keep plants flowering longer.

3. General Garden MaintenanceAdding mulch to landscape

  • Weeding: Stay on top of weeds to reduce competition for water and nutrients.
  • Mulch: Refresh mulch — apply bark around ornamentals and compost around edibles to retain moisture.
  • Pest Patrol: Watch for aphids, thrips, and caterpillars; use Insecticidal Soap or Neem Oil as needed.
  • Powdery Mildew Watch: Overcast mornings can lead to mildew on roses, begonias, and euonymus; treat early if spotted.
  • Standing Water: Remove any standing water to help reduce mosquito breeding.
  • Container Check: Make sure pots aren’t drying out too quickly — add Soil Moist to help retain water.
  • Houseplant Prep: Before vacation, tidy up houseplants and make a watering plan — ask someone to water if you’ll be away during warm weeks.

4. IrrigationA plant being watered by a drip system.

  • Inspect Systems: Check and adjust your irrigation — summer heat increases water needs.
  • Monitor Raised Beds and Containers: These dry out faster, so check soil moisture often.
  • Deep Watering: Focus on giving deep drinks to trees, shrubs, and vegetable beds.

  • Hydrangeas: Feed early June — they are hungry plants and need regular nutrients for big, beautiful blooms.
  • Citrus Trees & Containers: Provide a summer feeding to support healthy growth.

6. Lawn Care

  • Mow High: Raise your mower blade to help lawns withstand heat stress.
  • Irrigate Deeply: Water lawns deeply but less frequently to encourage deep roots.
