Set plant roots over this mound, spread roots, and fill in with soil. Firm the soil tightly 2 or 3 times while filling the hole. The first feeding should come in early spring as soon as leaf buds begin to swell. Clear away mulch and work plant food into soil around the plant. Second feeding should be made at the same rate and immediately following the first heavy bloom.
Many growers follow a regular monthly feeding program during the growing season with good results.
Feed again when blooms start to appear. In both cases work the fertilzer lightly into the soil to within 4 inches of the plant. The cultural practices differ but little in various sections of the country, with exception of timing of operations that depend upon climate. Artificial watering may be necessary if summer rainfall is insufficient. If soil is well drained, there is not much danger of overwatering.
