I want to trim my rubber tree because it is too tall, but many of the leaves have fallen off. Now, there are only a few leaves left, and they are all at the top.
I water it about once per week and fertilize about every 3 months using 19-6-12 Osmocote smart-release plant food. I live in Seattle, WA, so it has been inside about October-April, and I just moved it outside.
Also, instead of cutting off the branch, I was going propagate the trimmed section into a separate plant using air-layering. But where should I cut it?
I think the plant hasn't been doing very well because it lost a lot of leaves over the winter while indoors. I just moved it outside, so I hope to strengthen its stores before beginning the trimming/air-layering process.
I think I will follow @stormy's and @Bamboo's advice by doing the following:
- repot the plant and only use distilled water.
- cut down the mainstem to the highest lateral, and propagate it
- air layering on the side of the longest remaining lateral and propagate it
Does anyone have suggestions about the timing of these tasks? Here is my schedule: I repot first, wait 3-4 weeks, cut mainstem and propagate, wait 1-2 weeks, air-layer and propagate.
Also, just to be sure, where should I cut the mainstem and where should I perform the air layering on the longest remaining lateral? Here is a labelled photo of my plan:
