Self seeded poinsiena (mini acacia) preservation
To make use of self seeded poinsienna or other self seded perennials or trees, is it best to transplant them to a desired location at the end of the first summer, let them grow for a year before transplanting, or transplanting to a flowerpot to preserve away from wind and cold for transplanting the next year. Because of unusual drought this summer i have innumerable seedlings i never had before of which i want to save many if possible.
I do recommend that, if you would like to save as many as possible, you will want to bring some of these indoors over the winter. They will have better success indoors, than outdoors, typically if it is under a year old. After that, there is a good chance they will survive on their own.
