Deadhead Bloomers, Water Deeply - July's Garden Needs Love

By July, Lodi gardeners know that summer has arrived in full force. Long, sunny days and triple-digit temperatures can be hard on both plants and gardeners, but with a few simple maintenance tasks, your landscape can remain healthy, colorful, and productive all season long.

Rather than focusing on planting, July is the month to maintain, protect, and prepare for the abundant harvests and beautiful blooms that continue through summer and into fall.

Here's your July garden checklist.

Water Deeply

Water deeply and less frequently to encourage strong root growth.

• Water early in the morning whenever possible.

• Check irrigation systems for clogged emitters or broken sprinkler heads.

• Watch container plants closely—they often require watering daily during heat waves.

• Continue replenishing mulch to help retain soil moisture and keep roots cooler.

Deadhead Summer Bloomers

Removing spent flowers encourages many plants to produce another flush of blooms.

Continue deadheading:

• Roses

• Zinnias

• Cosmos

• Marigolds

• Coneflowers

• Shasta daisies

• Salvias

• Blanket flower (Gaillardia)

• Coreopsis

• Petunias

• Geraniums

A few minutes every week can keep your flower beds looking fresh through September.

Lightly Prune Where Needed

July is not the time for major pruning, but a little cleanup can rejuvenate many plants.

Lightly prune:

• Lavender after its first bloom to encourage fresh growth.

• Catmint (Nepeta) after flowering for a second bloom.

• Salvia flower stalks once blooms fade.

• Daylily flower stems after flowering.

• Spring-blooming perennials that have become leggy.

Avoid heavy pruning of trees and shrubs during periods of extreme heat unless removing dead or damaged branches.

Harvest the Vegetable Garden Often

Regular harvesting keeps vegetables producing longer.

Harvest frequently:

• Tomatoes

• Peppers

• Cucumbers

• Summer squash

• Zucchini

• Beans

• Eggplant

• Melons

• Herbs

Don't let oversized zucchini or cucumbers remain on the vine—they signal the plant to slow production.

Protect Plants from Extreme Heat

Several consecutive days above 100°F can stress even sun-loving plants.

Watch for:

• Wilting despite moist soil

• Sunburned leaves

• Blossom drop on tomatoes and peppers

• Scorched hydrangea leaves

• Crispy leaf edges on Japanese maples and newly planted shrubs

If a heat wave is forecast, consider providing temporary afternoon shade.

Create Temporary Shade

Temporary shade can lower plant stress without reducing healthy growth.

Easy options include:

Shade cloth (recommended)

• Use 30% shade cloth for tomatoes, peppers, roses, and flowering annuals.

• Use 40% shade cloth for leafy greens, herbs, hydrangeas, and newly planted shrubs.

• Suspend the cloth 12–24 inches above plants rather than laying it directly on the foliage.

PVC Hoop Supports

• Bend inexpensive PVC pipe over garden beds.

• Secure shade cloth with clips or zip ties.

• Remove once temperatures moderate.

Patio Umbrellas

Perfect for:

• Container gardens

• Hydrangeas

• New landscape plantings

• Small flower beds

Pop-Up Canopies

Ideal during prolonged heat waves to protect vegetable gardens or newly planted areas.

White Cotton Sheets

For short-term protection, suspend lightweight white sheets over plants using stakes. Avoid plastic tarps or dark fabrics that trap heat.

Watch for Summer Pests

Hot, dry weather often brings unwanted visitors.

Inspect plants weekly for:

• Spider mites

• Aphids

• Whiteflies

• Tomato hornworms

• Squash bugs

• Earwigs

Early detection usually means simple solutions.

Care for Your Lawn

Help your lawn survive the hottest part of summer.

• Raise your mower height slightly.

• Water deeply rather than frequently.

• Delay fertilizing cool-season lawns until temperatures begin to moderate.

Harvest Herbs

July is one of the best months for fresh herbs.

Harvest regularly:

• Basil (remove flower buds to encourage leaf production)

• Rosemary

• Oregano

• Thyme

• Sage

• Mint

Dry or freeze extra herbs now for use throughout the year.

Prepare for the Fall Garden

Believe it or not, July is when experienced gardeners begin thinking ahead.

Late this month:

• Order fall vegetable seeds.

• Start broccoli, cauliflower, cabbage, and kale indoors.

• Remove spent spring vegetables.

• Add compost to empty beds.

• Prepare planting areas for August and September.

Garden Tip of the Month

One of the best habits you can develop is taking a five-minute walk through your garden each morning. A quick stroll with a cup of coffee allows you to spot irrigation problems, weeds, insects, ripening vegetables, or thirsty plants before they become bigger issues.

A healthy July garden isn't about working harder—it's about working smarter. By keeping up with a few simple maintenance tasks and providing a little extra protection during our hottest afternoons, your Lodi garden will continue rewarding you with colorful flowers, fresh vegetables, and beautiful outdoor spaces well into the fall.
