Hi, Hetty. I now have some 8 plums and half are blooming. The tallest is about 7 feet tall and "y'd" at the top with three stems. The rest are in the vicinity of 4-5 feet. In the past I have taken them from the dirt by late Oct., cleaned the roots, put the roots carefully into a paper bag and just layed the entire stem system on a shelf in a semi-dark corner. So far-so good. I dare not plant them in the ground because our weather goes to both extremes. Is there a signal of some kind when I should leave them in their pots all year long. Of course, still bringing them inside for the winter. I always trust your advice.
Thank you very much.
