David when you get older you will have room.
I do not grow seeds and cut back on some of the trees I was bring in especially all the Brugmansias. Lots of room for pots. I have all of what you bring in except two or three but all mine stay in the pots. No digging and packing.
Some I will have to divide in the Spring because they really multiplied this summer. Especially the Tuberose they have been in the pot for 4 yrs. I have to keep those growing over the winter or I found I do not get flowers until almost winter. Now I get flowers in August, one year it was July until Sept they flowered.
