Thank You both Al and Sally.
Great and useful information. Root pruning and re-potting sound like the solution. I'll usually "refresh" a pot before it goes outside, but not to the extent that Al has shown.
Guilty confession....I've used a bloom booster. It's so seductive to think a bit of fertilizer will give me incredible blooms, knowing in the back of my head it's it's probably just hyped up advertizing. I'll try the Foliage - Pro and dump the bloom booster. .......how often do you fertilize your pots? In my gardens, I rarely use fertilizer. Good soil and compost have always done the trick. One more question; pot size? Does "bigger is better" apply?
The castor bean is beautiful. I grow them from seed as annuals for a bit of the exotic in the garden, but never thought of overwintering them. Do they go dormant like the brugs?
Sally, I'm amazed you get a plant that size with that number of blooms from a cutting. It's too late for me this year, but next year I'll give it a go.
Once again (even after 40 years of gardening) I find folks have some wonderful information to share, so Thank You for sharing.
Spring will be here soon, but in the meantime we have our basements and grow lights to keep us busy!
Take care
Glenn
