July Garden Chores

Updated for July 2021

With the heat, humidity and occasional rains, many gardens have exploded this month. Fortunately, we gardeners can enjoy them with a streamlined list of chores. Basically, July involves weeding, watering and watching. Here’s what we mean:


  • lilie to deadhead

    Lilies are lovely in bloom. Once the bloom is spent, not so much. Deadheading keeps your garden neat.

    I make a point of weeding casually almost every day. By this time of year, you probably know which weeds are in your garden and where to find them. Grab them when they are small, after a rain and when you first see them. The goal is to prevent them from going to seed.

  • Deadheading isn’t exactly weeding, but removing spent blossoms will make your yard look neater and it encourages plants to keep on flowering. Focus on the plants with spent blooms that are most noticeable, such as geraniums, lilies and daylilies. Roses also do best with regular deadheading, cutting the blooms off just above a set of five leaves.
  • You can also cutback some early summer blooming shrubs, such as spirea, or perennials that have finished blooming, such as catmint. Cutting off the blooms after they are finished gives the shrub or plant a neat shape and you may get a second round of blooms in a month or two.
  • Speaking of plant hair cuts, if your container plants look messy, give them a trim. They’ll keep on flowering and  look even better.
  • If you are feeling especially active, now is a good time to prune or shape those shrubs that are starting to look straggly.


  • To reduce disease, water early or late in the day. Keep the spray pointed toward the soil (not the leaves!).
  • Be especially diligent about watering any trees or shrubs that were planted this year. Water deeply every few days unless there is a good rain. Given how dry parts of Minnesota have been in 2021, be sure to give all your trees a deep watering.
  • Are you watching your rain gauge? We can get lots of rain or very little from the storms that are so common this time of year. Monitoring rain and making sure your vegetable gardens are getting at least an inch of rain will keep them productive.


  • japanese beetle july

    By July, Japanese beetles are out in full force. Check your roses, green beans and just about anything else.

    By now, many gardeners have already spotted their first Japanese beetle. Ugh. We have lots of information on the blog about JBs, but the most environmentally safe way to control them is simply picking them off the plant and knocking them into a bucket of soapy water. Do it in the morning when they are slow. Get your kids involved! It’s a great job for little fingers. Also, if you have not heard about the winsome fly, a parasite that attacks Japanese beetles, check out this post on the on the My Northern Garden blog. Many gardeners are reporting lower numbers of Japanese beetles in 2021.

  • Watch your vegetable garden closely for signs of common summer problems, such as early blight or blossom end rot on tomatoes or powdery mildew on cucumbers.
  • One of the best things to watch for in July is ripe fruits and vegetables! From the sour cherries that should be ripening now to green beans, cherry tomatoes, cucumbers, kale, zucchini and more. To avoid gargantuan vegetables, pick early and pick often.
  • Keep on picking herbs, too. If you aren’t sure how to use them, consider freezing them. Some herbs freeze well in logs or in pestos. Or try this basil gelato!

A few other things . . .

  • Have you set your mower up yet? During the hot time of the year, mow your grass at the highest setting. Longer grass blades will shade the roots and keep grass healthier. With all the dry weather we have had, don’t be in a rush to mow. Your grassroots appreciate the shade.
  • If you want to extend the season, plant quicker growing crops now. Lettuces and other greens should go in shadier spots (they really prefer cool weather!) but bush beans can be planted now and be ready to harvest in early September.

    My garden has never looked so good. Probably because it’s the only place I feel safe in going to daily without wearing a mask.

      Good for you! Enjoy that garden.
