air layering to reduce a large Hibiscus sinensis
I inherited a rather large Chinese Hibiscus standard that is about 7' tall from bottom of pot to top of canopy. It does not seem to be grafted.
The roots are mostly feeder & encompass the *entire* pot. It's a big ol' pot from Walmart, the biggest I've ever seen anyhow. It's about 24" across & at least that tall.
I'd like to air layer this tree to reduce the length of it's trunk. It would make a lovely table top patio tree if I can do this. The trunk is about 3" thick. Can anyone advise me as to whether I have any other options with thissort of material? I just pruned it heavily so that I can bring it in for the winter. I expect Spring time is the best time to carry out such a feat?
