Month-by-Month Guide to Vegetable Gardening
The bottom line: The weather can still work against you—keep those row covers handy in case of a nighttime cold snap—but otherwise you should be getting into full swing.
Check soil temperature regularly with your thermometer. When it consistently registers at 60ºF or above, you have the go-ahead to plant some warm-season crops.
If you didn’t start your own seeds, buy transplants and seedlings of early-season crops like radishes, spinach, onions, leeks, lettuce, cabbage, beets, peas, Brussels sprouts, and carrots.
Begin setting out your early-season crops. Try to pick an overcast day to minimize transplant shock—the stress that occurs when plants are moved from a cushy greenhouse environment to the harsh real world. Be sure to water well at planting time. When finished, add a two- to three-inch layer of mulch to suppress weeds and keep in moisture.
For greens, sow seeds directly in the garden where they’ll grow. Plant them in succession, every few weeks, for a continuous harvest through the season.
Until newly transplanted seedlings develop root systems, make sure they don’t dry out or you’ll lose them. And stay on top of weeds, catching them before they begin to spread.
