July garden tips & tasks

Summer is in full swing. Here’s how to enjoy the garden and it’s July bounty:

Early in the month

Geraniums

Cut geraniums and other summer annuals to encourage them to grow fuller.

In the kitchen garden, pick zucchini, summer squash and cucumbers while they are still small and tender.

Plant a second crop of those summer vegetables that grow quickly: bush beans, squash and cucumbers are easy favorites.

Watch for Japanese beetles. Experts don’t recommend Japanese beetle traps, which may attract more beetles to your landscape than would normally visit. Pluck them off the plants and drop them into a pan of soapy water.

If summer annuals such as coleus or geraniums are getting leggy, cut them back to encourage them to grow bushier. As a bonus, root the cuttings in water to have even more plants.

Before you leave for vacation, arrange for someone to water annual, vegetable and perennial beds and container gardens while you’re away. Make it easy for them: set up sprinklers in strategic places and hire a neighborhood youngster to turn on the faucet if it doesn’t rain.

Mid-July

Zinnias

Cut zinnias often. The more you cut, the more they bloom.

Bearded irises can be divided every three to five to years; mid-July is a good time to do it.

Lawn growth may slow down in the heat, but you may still have to mow. When you do, only cut about a third of the lawn’s height.

Cut chrysanthemums back in order to delay flowering until fall.

Herbs, annuals and perennials growing in containers need water every day when it’s hot. Don’t let them droop.

Keep cutting summer flowers such as zinnias and cosmos often; the more you cut, the better they bloom.

Later in the month

Tomatoes

Keep the soil evenly moist for tomatoes.

It’s hot, so get out early in the day to work in the garden. Drink plenty of water, wear a hat and use sunscreen.

Keep the soil around tomato plants evenly moist. Inconsistent watering can cause tomatoes to develop cracks.

Some summer flowers that grow tall may need staking to keep them from toppling in a heavy rainfall.

Continue to deadhead plants – cut off the spent flowers – to extend the blooming period.

Don’t forget about shrubs and trees planted this spring; they need an extra dose of attention in this heat. Give them a slow drink from a dripping water hose once or twice a week. A layer of mulch around newly planted threes and shrubs helps keep the soil moist longer.

Check the mulch in perennial and annual beds. Add more if it’s beginning to look thin. A good layer of mulch will help keep soil moist longer in the summer heat.
