The seeds of some milkweeds need periods of cold treatment (cold stratification) before they will germinate. [12] To protect seeds from washing away during heavy rains and from seed–eating birds, one can cover the seeds with a light fabric or with an 13 mm (0.5 in) layer of straw mulch . [ 13 ]
The aquatic milkweed is commercially available by both seed and propagated plants. Seed readily germinates, and mature flowering plants can be grown in as little as three to four months. Plants can be successfully grown in containers as small as a quart, and amount of stems increases with size of container. [ 3 ]
In agriculture and gardening, transplanting or replanting is the technique of moving a plant from one location to another. Most often this takes the form of starting a plant from seed in optimal conditions, such as in a greenhouse or protected nursery bed, then replanting it in another
