It is preferable to transplant annuals in a fine, loose loam, and never to transplant them in a heavier clay soil, which will pack and dry out. Upon the size of the plants will depend the care that it is necessary to give them immediately after transplanting. The smaller the plants the more care will be required in careful watering and shading during the hot portions of the day. While with proper care annuals may be transplanted at any season during the spring or early summer, yet the late spring (May through June 15th) is preferred. Annuals will develop best outdoors if they are transplanted at least two weeks in advance of the hot summer months. Frequent shifting, in pots or flats, is very beneficial through promoting the growth of fibrous roots which make transplanting more successful.
