Hi! I am looking for some advice on my jade plant. 1. It’s getting real “leggy” (not sure if that is the right term- but I’m wondering if there is something I can do to help it grow fuller? 2. Some of the leaves have white “dust” on them- what is it? Can I get rid of it? I was reading online and they said to take those leaves off but then it’ll just be even more leggy! Any advice is appreciated :)
