To begin, plant new transplants and seeds in a prepared soil. These amendments will loosen tight clay soils and hold moisture in sandy ones. The improved soil promotes abundant root growth and healthier plants. Just like throwing a blanket over the baby stroller, cover new seeds with garden row-cover fabric. By preventing the top of the soil from drying out, fragile seedlings will not die between the time you water in the morning and evening.
Row covers also shade new transplants.
When you first bring the transplants home, shuttle them in and out of the house or other shelter for the first few days. During the day, place them in an outdoors protected area, such as a porch. This gets them accustomed to the dry air and wind. Then transplant, throw the row cover over them and anchor the corners with U-shaped wire pins inserted into the soil. You also can use rock weights.
