My daughter has a swimming pool, she puts them in that and has had no problem. For the past four years I have been participating in a spring perennial swap with a group of friends. The advantages include a social time for us to interact as well as FREE plants and FREE information. It is a great incentive to get out in the garden in the spring and start cleaning up and dividing plants that you might have in your own garden. It's very easy to plan.
First someone can volunteer to be the hostess and schedule a date.
The hostess then notifies the previous participants of the date either via email, newsletter, telephone, etc. Each person is asked to bring their swaps in containers labeled with the plant name and information such as color, height, growing conditions, etc. As people arrive they sign in with their name and number of swaps they brought. After brief introductions and descriptions the swap starts with the hostess picking first then proceeding in order of arrival. Any left over or unwanted plants can be free choices at the end or we have used them to create gardens at our local schools and parks.
