July.

Keeping what you've planted alive

• Check container plants daily

  Pots dry out fast in heat and can need watering twice a day. If a container wilts, you've already lost yield — the plant recovers, but it stops making fruit for a beat.

• Control mosquitoes — empty stagnant water

  Any container that's held rainwater for more than three days is a nursery. Saucers, empty pots, wheelbarrows, the folds in a tarp.

• Inspect plants for insects and disease weekly

  In July, an early tomato hornworm or a spot of blight can go from problem to crisis in a week. Catch it small.

Nudging the harvest along

• Harvest often, even when you don't need it

  Zucchini, beans, cucumbers, and squash stop producing once a mature fruit sits on the plant. Picking daily keeps the plant convinced it hasn't finished its job.

• Fertilize tomatoes and peppers lightly

  They're heavy feeders now — carrying fruit takes calcium, potassium, and consistent moisture. A side-dress of compost or a diluted fish emulsion every two weeks keeps yields steady.

• Pinch back basil, mint, and oregano

  Once herbs bolt to flower, the leaves turn bitter and the plant slows. Cut above a leaf pair every week to keep them producing until frost.

• Deadhead annuals and perennials

  Zinnias, cosmos, salvia, dahlias — they'll keep blooming as long as they haven't set seed. Once seed forms, they stop.

Setting up the fall garden

• Do the fall garden math this week

  Fall gardening is arithmetic: count backwards from Oct 15 (first frost in Hunterdon), add 14 days to each crop's days-to-maturity, and that's your last safe sow date. Winterbor kale at 65 DTM lands on July 28. See the Fall Garden Planning guide for the full framework.

• Start broccoli, cabbage, and Brussels sprouts indoors mid-month

  For a fall harvest, they need to be in the ground by late August — which means the seedlings have to be ready. Get them under lights or on a shaded porch by July 15. Brussels sprouts especially need the full 100 days; start those first.

• Divide bearded iris and cut leaves back to 6″

  Iris rhizomes rot when they get crowded. July is the window: dig them, cut the fans back so they don't topple, and replant. They'll settle in for a stronger spring bloom.
