Succession Planting: Keep It Coming

A smart succession plan means fresh food from spring until snowfall.

Doubling Up

When planning successions and selecting vegetable varieties, consider how two or more crops might share the same space, a practice known as interplanting. Pairing plants with different maturity rates, like slow-growing Tuscan kale and lettuce, works particularly well because the lettuce heads mature before the kale grows big enough to shade or crowd them out. 
 
Mixing plants with complimentary growth habits, such as lettuce, which has a deep taproot, and shallow-rooted scallions also makes efficient use of space and increases yields. So does planting short crops, such as beets and radishes, along the bottom of a trellis planted with peas, beans, or cucumbers.
 
Planting Tricks
Plant spacing also influences yield, and many crops can be planted closer together than most sources recommend. Tuscan kale seedlings are typically planted a foot apart, but spacing them at 10 inches encourages the development of small, long-bearing, tender-leaved plants. In good soil, a carrot needs only 4 square inches of space to grow in—so try sowing them 2 inches apart in a row, with 12 rows to a 30-inch-wide bed. 
 
Some crops, including spinach and carrots, must always be seeded directly into the garden. Others, such as tomatoes and peppers, grow best when planted as seedlings. But many vegetables—including all greens, summer and winter squash, lettuces, and herbs like parsley and basil—grow well from seedlings or by seed. A simple way to get a staggered harvest of these crops is to sow seed and transplant seedlings into the garden at the same time. To keep each garden bed full and producing, try to have seedlings on hand and ready to go in whenever a space comes available. 
 
Climate Considerations
Understanding how crops grow, learning to interplant and plan successions, and choosing varieties that thrive in specific conditions is the best way to overcome climate challenges. Gardeners in warm regions must take advantage of their tame winters by growing cabbages, greens, and peas, and appreciate their summers-and the melons, peppers, and eggplants that thrive in hot weather. 
 
Mild summers give gardeners in cool climates the opportunity to grow a wider range of vegetables, including heat-tolerant varieties of cool-season crops and short-season varieties of heat-loving ones; and with the help of season-extension tools, they can grow greens and root crops into the winter, as well. Really, planning carefully and using a garden's space wisely makes it possible to grow more vegetables almost anywhere. It is, after all, a generous earth.
