You can sow peas about a month before your last frost, and they'll do well as long as weather stays cool.

Turnips and peasare fitting companions in the garden. Both can be sown leading up to spring — peas about a month before your last frost and turnips about two to three weeks before your last frost. You can plant turnips where you’ve grown early peas, and you can plant both again in fall. With a quick search, you’ll also find many recipes that combine these two dissimilar yet complementary crops — with carrots and dill, with meats, in soups, or in curries. The recipes here offer a variety of flavors and some unique ideas for using turnips and peas — in pesto, with miso, and with mint. These lovely dishes can help you use up any turnips you stored through winter and also welcome your spring harvest.

Growing Peas

When to plant. Sow about one month before your last frost. Where summers are cool, make additional sowings three weeks apart. Peas produce poorly in hot weather, so an early start is a wise strategy. In climates with mild winters, sow a second crop in late summer.

How to plant. All peas benefit from support. Install a 6-foot-tall trellis before planting long-vined cultivars. Compact cultivars can be staked with woody branches or tomato cages.

Prepare a wide planting bed by loosening the soil to at least 10 inches deep while mixing in compost. Do not use fertilizer unless your soil is very poor. Plant seeds in a double row, with a row of seeds on each side of the trellis. Poke seeds into the prepared site 2 inches apart and 1 inch deep. Thinning is not necessary.

Harvesting and storing. To avoid mangling the vines, use two hands to harvest peas. Harvest ripe peas daily, preferably in the morning. Pick snow peas when the pods reach full size and the peas inside are just beginning to swell. Immediately refrigerate or promptly blanch and freeze to maintain crisp texture.

‘Golden Ball’ or ‘Orange Jelly’ or ‘Boule D’or’: mainstay of European turnips; seeds from France; yellow; sweet and mild

Growing Turnips

When to plant. Sow a spring crop of salad turnips two to three weeks before your last frost; plant seeds up to 50 days before your first fall frost.

How to plant. Turnips can be planted in spaces vacated by early potatoes or peas. They grow best in fertile, well-drained soil with a pH between 6.0 and 7.0. Mix a light application of a balanced organic fertilizer into the planting bed unless ample nutrients remain in the soil from the previous crop.

Sow turnipseeds about 2 inches apart and ½ inch deep. Turnips can be planted in rows spaced 6 inches apart, or you can broadcast the seeds over the bed and pat the soil to firm them into place. After seeds have germinated, thin turnips to 2 inches apart. Two weeks later, when plants reach 4 inches tall, thin turnips to 4 inches apart (and enjoy the greens from the pulled plants).

Harvesting. For best flavor, harvest turnips when they’re less than 2 inches in diameter. Store the greens in the refrigerator or freezer. Store roots (with tops trimmed back to 1 inch) in the refrigerator for several weeks.
