The Gardener's July Calendar ~ 2017


It always seems like the summer months go by faster than the winter months, at least for me. So here we are in July, with the heat of summer with high humidity about to be a permanent reality in the Northeast. At first it may seem that this is the month to surrender and just hide in the house with the A/C. But there is a lot to do in the garden this month, so getting outside early morning or early evening is key to getting tasks in and avoiding the hot sun. (Remember to stay hydrated as you work out in the heat.)

Here are some things to keep in mind:


  • Japanese beetles — Now that the first plague has passed (gypsy moths), now it's time for Japanese beetles. Nothing seems to be more dependable then the awakening of Japanese beetles in July. The best way to get rid of them is by going out in the early morning or late evening, when the bugs are sluggish, and shake the branches, blossoms or leaves they are sitting on over a cup of soapy water so the beetles fall in. I don't use anything fancy — any dish soap will do. Oriental beetles are also as annoying as the Japanese beetles. Together, they eat foliage and flower petals. I spotted a few already in the garden.
    In the past I've tried to spray beneficial nematodes on my grass to get rid of future Japanese beetles. I have seen less beetles over time, which could be due to the removal of the lawn or the nematodes. But because my neighbors do not take action to get rid of their Japanese beetle grubs, I still get their bugs visiting my garden.
    I do stay away from the Japanese beetle traps, those hanging bags with the lures, because they seem to attract every one in the neighborhood. Now if a neighbor a block over wants to set one up, that's fine with me ...
  • Deadhead flowers — This is a time-consuming but important task for a large garden. Deadheading makes plants concentrate their efforts on producing new flowers as opposed to seeds. (Of course, if you want seeds, skip this step.) I find that I am constantly deadheading roses, daisies, marigolds and zinnias this month.
  • Hummingbirds and butterflies — Keep those feeders clean, especially as the temperatures get hotter! Forgoing the feeder? Try growing these plants to attract them to your garden instead. Keep a lookout in the garden for black swallowtail caterpillars and monarch caterpillars on your plants. 
  • Fertilize! — Potted plants need the most fertilizer, vegetables after that. I like to use an organic fertilizer. I've had very good luck with Organic Plant Magic and Dr. Earth's concentrated 3-3-3 liquid fertilizer. A seaweed-based liquid fertilizer works well, too, even if it's smelly. You should fertilize plants every two weeks, but I admit, this is something I have trouble keeping up with. 
  • Harvest garlic — By now you should have cut off your garlic scapes. (Did you make this delicious pesto from them?) At mid-month, it should be time to harvest garlic. I wait for half of the lower garlic stem and leaves to turn yellow. The trick is not to wait too long to dig them up, or the cloves will begin to separate which effects how long they can be stored. I hold off on watering before I dig them up. When I decide it's time to harvest them, I use a small hand shovel to dig them out (don't go to close or you may cut the bulb). I let them dry on my patio for the afternoon and then I shake off the excess dirt from the roots and hang them to dry. In my house, the coat rack behind the back door provides enough air circulation and keeps them out of direct sunlight. (It also appears to house guests that we are warding off vampires.)
  • Prune tomato plants — On tomatoes, suckers will grow in the crotch where a branch meets the stem. Removing these helps the plant by increasing the airflow which prevents diseases like late blight. A plant with more suckers typically produces smaller fruit. Also, be sure to remove any yellow leaves from the plant. I remove the bottom leaves (with about a 6 inch clearance from the first leaf bract to the soil) to prevent water from splashing up and starting fungal infections on the leaves. I've read that growing lettuce as a ground cover under tomatoes helps prevent water splash up on the plant, an interesting thought, but I haven't tried it out myself yet.
  • Flower seeds — There is still time to plant a last batch of zinnias, tithonias, cosmos and sunflowers, but get them in fast. Like, now.


  • Enjoy the Fruits of Your Labor — When it comes to harvesting fruit, such as raspberries and blueberries, pick regularly (perhaps every day) to avoid losing your crop to birds. If you don't harvest your vegetables regularly, they can over-ripen and begin to spoil on the stem. A really good resource for growing berries is Homegrown Berries by Terri Dunn Chace.

    Many edible flowers can be harvested all summer long (learn more here). If herbs try to flower, pinch them off so the flavor is stronger in the leaves. The one exception to this rule I allow is oregano. I grow more than I can use, and the flowers attract bees like crazy, which help my other plants.
  • Prevent injuries — To prevent injuries in the garden, it's good to stretch before you go outside. To view five recommended exercises I discovered online, click here
  • Fruit trees — Keep an eye on fruit trees that may have branches starting to sag from the weight of the fruit. My grandfather used to grow Bartlett pears and by late summer, his whole tree was propped up with stakes to keep the fruits from breaking the branches. You can also try tying kitchen twine to sagging branches to the central stem for support. It didn't work perfectly, but did help. I've already noticed that one of my plum tree branches has split from the weight of the fruit, so as an emergency measure, I'll wrap the branch, but after harvest, I'll need to remove it.


  • Soil tests — Is an established plant not performing the way you were hoping it would? Get your soil tested to see what nutrients it may be missing. The University of Connecticut offers a basic soil test for $8 for homeowners. Using a small trowel or bulb planter, take samples of soil from 10 different spots in the sample area. Mix the samples in a container and then take a one cup sample to send out for analysis. Once your test results return (the website estimates 7-10 days) you can use the information to determine what the soil needs for correcting. Most garden centers are willing to help you decipher the guidelines if it seems confusing.
  • Plan Your Fall Garden — Growing lettuce, carrots, beets or more for the fall? Start planning now. I am planning to use my books (such as Niki Jabbour's and Eliot Coleman's) to do a better job of making my fall and winter gardens this year. A few years ago I planted peas in my cold frame in the fall. The plants grew slowly over the winter with the protection (even with some of the coldest temperatures) and produced a spring crop of peas earlier then the peas I sowed in the spring.

  • Travel to gardens — This is the perfect time to get ideas and view other's creations, whether public or private gardens. Seeing what is blooming now also helps you expand the blooming palette in your garden! Some previous places I've visited include Winterthur and The New York Botanical Garden, as well as the Lily Show at Tower Hill Botanic Garden. Other fun destinations can be found here.
What's on your to-do list this month?

I garden in Zone 6b in Central Connecticut.

  1. Last month on a trip to Hartford, my daughter and I hit up a rest stop on 84. Upon getting out of the car we noticed one caterpillar, then another, and another... until it became apparent that the entire parking area and sidewalks were living carpets of gypsy moth caterpillars. Areas of trees were taped off to keep people from walking under them and getting rained on by frass or caterpillars.

    Now, I'm fine with spiders, bees, whatever, but having lived through the hideousness of the 1980s gypsy moth outbreak, I had a literal case of the tap-dancing heebiejeebies all the way through that rest stop. I have an old propane-torch "flame weeder"; had I discovered a scene like this closer to home I would have put it to use... carefully, unlike the idiot who started the forest fire with his, but...yeah.

    I was SO relieved to read that the biocontrols finally kicked in and killed off much of the population. What a horrorshow.

    One change to the to-do list for me: put on sunscreen AND insect repellent EVERY time I go outside. With the boom in mosquitoes, ticks and their accompanying diseases, I'm not taking chances. Deep Woods OFF, head to toe; the classic gardener's cologne.

    1. Good advice about bug repellent! And yes, now I see the gypsy moths flying around the garden and I'm hoping we are not due in for another round of gypsy moth mayhem in a few weeks!
