Gardening Checklist for August

Print Friendly, PDF & Email

August is a month to enjoy the bounty of your edible harvest and the glory of late summer flowers. Even as you reap the rewards of a well-tended garden, prudent gardeners will prepare for fall, perhaps the easiest garden season of all. If you’ve never planted a vegetable garden before, fall is the best time to start.  


August Checklist:

Pick, pickle, preserve 


The hottest summer days bring more tomatoes, peppers, squash and cucumbers to enjoy. This is also the time to get the most out of annual herbs like basil. Pinch back flowers to extend the harvest and savor the leaves in herb butters and pesto. Read more about herbs here.

Sun-ripened tomatoes and peppers are delicious in summer salads. Try canning a small batch of salsa with extra produce from your garden. A bumper crop of cukes means plenty of pickles. Look for quick pickling recipes to save time. 

Cut summer flowers for bouquets 

When it’s too hot to go out in the garden in the middle of the day, head out early and snip zinnias, sunflowers, daisies and dahlias for abundant cut flower bouquets

While you’re in the garden, pay attention to perennials like coneflower and coreopsis that can look rugged in late summer.

Rejuvenate them with some timely deadheading, and if it’s been awhile since you’ve fertilized, give them a dose of all-purpose plant food.

Aerate and reseed lawn

Prepare for the fall season by aerating and reseeding your lawn. Give cool-season grasses time to grow before first frost.
