Caring for hostas in pots
I have some wonderful hostas that grow in pots. Some, I've had for years. They seem to thrive on neglect. As long as I keep them watered and on "pot feet", they look good. I have no idea of the varieties.
I'm wondering if I should repot them and maybe move them to bigger pots. The oldest one has been in the same pot for 6 or 7 years. It's starting to sprout and I would say that 70 to 80 percent of the surface is covered with crowns.(It's about a 14 inch pot) I've no idea how many crowns there are in that pot. It didn't bloom last year, which doesn't bother me other than knowing it would bloom if it were happy. Do I have to divide it? It is just such a gorgeous plant, I hate to divide it. Would just a bigger pot work? How much bigger should it be?
As all pots lose soil every year, can I just add soil to the top or will that rot the crowns?
Every one I have (except the the one with the big chartruse leaves) is starting to break ground, so I need to work on them this week.
Thanks for your help.
