Producing native plants as container seedlings
Crops of native plants should be planned to allow enough time for seed collection, seed processing, seed treatments and stratification, greenhouse growth, and hardening. An ideal container nursery consists of a production greenhouse, a cold frame, a shadehouse and refrigerated storage. Four propagation methods can be used to produce native plants: direct seeding, germinants, transplants, and rooted cuttings. The choice of container should consider seedling growth, species characteristics and outplanting site. Most native plants can be grown reasonably well under a standard greenhouse environment and in commercial potting mixes. The type and amount of hardening will depend on the species characteristics and the future use of the plant. Nursery managers must be aware of variation between species, seed sources, and annual seed crops. Successful growers must acquire direct experience in producing each species tinder their own nursery system.
