from The Old Farmer's Almanac
May is a green as no other,
May is much sun through small leaves,
May is soft earth,
And windows open to a South Wind.
–Amy Lowell (1874–1925)
For many gardeners, May is the biggest transplanting month. A seedling’s move to the outdoors can be traumatic. Here are some tips to minimize transplant shock:
• Be sure that the plants “harden off.” During the plants’ last week indoors, lower temperatures a bit, withhold fertilizer, and water less often.
• For the last 7 to 10 days, bring seedlings outdoors for increasing periods each day, first placing them in dappled shade, protected from winds, and then gradually moving them into full sun and wind.
• Do not leave outside if there is danger of frost. See your frost-free dates.
• When buying transplants at a nursery, choose stocky plants with deep-green foliage. You’ll need to harden off these transplants, too.
• Ideally, the transplants that you grow or buy are in individual containers so that you do not disturb the roots of neighboring seedlings when you remove each plant.
