- Thin seedlings (greens, carrots, beets) when plants reach 1-2 inches tall or have two sets of “true leaves” to thin out any crowded plants and give the them room to grow.
- Side-dress cool-season crops with compost, and mulch around the base of plants to keep their roots cool and moist.
- Continue to direct sow cool-season crops that mature quickly, such as arugula, chard, endive, lettuce, spinach, mustard, and radish.
- Direct sow other crops: beets, kale, leeks, carrots, parsnip, turnips, peas, potato, and herbs (parsley, chervil, sage, lovage, thyme).
- Start indoors: cucumbers, squash, pumpkin, melons, bush and pole beans.
- Set out purchased transplants or plants started from seed indoors to “harden off” (or get used to the outdoors); water frequently until planted so they don’t dry out.
- Transplant sprouted potatoes started indoors.
- Avoid late plantings of some transplants, such as broccoli and cabbage that may be on sale at local garden centers, since approaching warmer weather may prevent these crops from reaching full maturity before going to seed.
- Make sure to trellis vertically-growing plants, such as peas, cucumbers, beans, and other climbing plants before the plants grow too big and become unmanageable.
- Hold off planting warm-weather plants, such as tomatoes and peppers, until well after the last average frost date (check recommendations specific to your growing area).
- Start sweet potato slips indoors before Start sweet potato slips indoors before planting slips outside later in the summer.
