July Gardening Checklist for East Contra Costa County
Summer is in full swing, and while the temperatures are rising, there is still plenty to do in the garden. July is an excellent time to maintain your landscape, support pollinators, and prepare for late summer blooms.
Water Wisely
As temperatures increase, proper watering becomes critical.
- Water deeply and less frequently to encourage strong root systems.
- Water early in the morning to reduce evaporation.
- Check irrigation systems regularly for leaks and clogged emitters.
- Add mulch around plants to help retain moisture and regulate soil temperatures.
Keep Pollinators Happy
Bees, butterflies, and other beneficial insects are active throughout the summer.
Consider planting:
- Zinnias
- Cosmos
- Sunflowers
- Salvia
- Lavender
These plants provide valuable nectar sources while adding color to the garden.
Deadhead Summer Flowers
Removing spent blooms encourages many annuals and perennials to continue producing flowers.
Regular deadheading is beneficial for:
- Zinnias
- Cosmos
- Marigolds
- Coreopsis
- Shasta daisies
Harvest Herbs Frequently
Herbs often perform best when harvested regularly.
July is a great time to enjoy:
- Basil
- Oregano
- Thyme
- Sage
- Rosemary
- Mint
Frequent harvesting encourages fresh growth and improves plant health.
Watch for Heat Stress
Signs of heat stress may include:
- Wilting during the evening
- Leaf scorch
- Premature flower drop
Provide temporary shade for sensitive plants during extreme heat events and monitor soil moisture carefully.
Looking Ahead
Now is also a good time to begin planning for fall vegetable planting and cool-season color. Gardeners who prepare early often enjoy more productive fall gardens.
Happy Gardening!
