I have 3 schefflera arboricolas that are pretty young and I want to raise them into trees instead of wide bushy shrubs.
I know this will take years, but I am looking for advice on what I need to do to achieve this. I believe a crucial part is ensuring not to prune the tops so they continue to grow straight up instead of branching, but what else?
- Should I occasionally be removing lower stems, or not yet?
- Should I be doing something specific to increase the strength of their trunks?
- Do I need to try staking them early or wait until necessary?
- Are there specific fertilization practices I should be using other than the usual?
I attached a photo of one, but the other 2 are very similar as they were all purchased at the same time from the same vendor.
Thanks for any help people can provide!
