Summer Chores
Pruning
Mint
Mint can be harvested at any time once it is three to four inches tall. In early summer, when mint is growing well, pinch off smaller stalks and use it. Larger stems, prune four or five inches and make another plant.
Basil
It’s best to start early when the seedlings are about six to eight inches tall and have three to four sets of leaves. At that point, each plant is likely a single stem. Pinch that main stem back to a strong set of side shoots, removing about one-third of the plant. After that, prune my basil plants every two weeks or so during the summer to stimulate plenty of growth.
- Cut the garlic scapes! By cutting them off as soon as possible, the plant will direct its energy into making bigger bulbs.
- Pre-treat broccoli with BT as soon as you see any white moths.
- Prune spring-blooming shrubs such as forsythia, lilacs, weigela, viburnums, daphne, quince, and deutzia by mid-July at the latest. If you do it any later, you will cut off next spring’s blossoms.
- Do the Chelsea Chop! To keep fall bloomers like asters, mums, and phlox shorter and more full and inspire them to have double the number of flowers, cut the plants back by half. Doing it before the 4th of July will give the plants time to form new growth and extra blossoms.
- Fertilize. By the 4th of July, give shrubs and perennials the last side-dressing of compost, rotten manure, or fertilizer. This will give any new growth time to harden off before frost.
- Replace early crops. Most spring vegetables, such as lettuce, and spinach, have been harvested by early July. Pull them out and make room for some new plants. In most areas, there is still time to plant more beans, summer squashes, and cukes. Seeds should germinate fast in the warm soil.
- Start seeds of lettuce, chard, and brassicas, including broccoli, to pop into beds as they empty. They love the cooler days of late summer and early fall and will be productive until a hard frost.
- Thin the carrots if you haven’t done so already. They need to have room to develop those big fat roots you are craving.
- Tidy up the spring bloomers. Cut back the iris stalks, pull out tulip and daffodil foliage once it has turned brown and died back, and deadhead the peonies by cutting back to the next set of 5 leaves on the stem.
- Speaking of deadheading, remove spent blossoms from rhododendrons, azaleas, and lilacs to make way for new growth.
- Yank those invasives before they gain a foothold!
- Pinch the tomato suckers. You can leave the bottom two suckers on the plant because they will produce fruit but remove the rest as they form in each leaf axil up the stem. This will keep the plant from becoming too bushy and blocking light from reaching developing fruit.
- Add mulch and weed, weed, weed!
