Careful and frequent attention must be devoted to the maintenance of annuals during the growing season and especially during the flowering season if the best success is to be obtained with this type of garden. Those annuals like the mid-season and late asters need only normal care. Such plants have but one flowering season and it is rare that any secondary flowers are developed on these plants through intelligent cutting, as is the case especially with the snapdragons and also with calendulas, marigolds, and pansies. The snapdragon perhaps is one of the most valuable flowering annuals for a long period of bloom. It will begin its bloom in late June or early July and will continue to bloom until frost retards its growth. Such plants however, will not produce an abundance of fine flowers if encouraged to persistently produce flowers throughout the entire growing season. The snapdragon will produce the best flowers if given a rest during some part of the summer. For instance, plants which begin flowering in late June or early July should be permitted to flower for four or five weeks. They should then be severely cut back to a height of four inches to six inches and a new growth permitted to develop and produce flowers during late August and September.

The one most important duty in the successful growing of annual flowering plants, in order to continue their period of bloom, is to keep all portions of the plant from developing seed pods. Those branches which have produced flowers should be removed as soon as the bloom has ceased. Most of the annuals like the calendulas and marigolds are encouraged to produce more bloom through this process of keeping seed pods removed and the branches severely cut back. Other annuals like the annual larkspur, the matricaria, the annual baby's-breath, and the bachelor button will not develop a secondary growth, and must therefore be planted in successive sowings to secure a continuous supply of flowers.
