dwarf lilac for highrise balcony?
Hi, I come from the Balcony Gardening forum. My nursery has Dwarf Korean and Miss Kim Dwarf Korean lilacs (both grow 4-6'). Miss Kim is on sale 5G. bucket for $25, usu. $40. 2G. buckets are $20.
I've read that pruning can be fussy. I wouldn't want them to go much bigger than the existing 5G. size. Would this be manageable? Also, their zone hardiness goes to 3--I could wrap and winter them outside or put them in my underground garage?
Also, does one need to prune roots on something like this? I'm new to gardening--just did 3 balcony rail pots of annuals last year--so this would be a novice's investment. Thanks for your insights! I face west, so get good late afternoon sun.
