I’m glad you mentioned your lemon tree. This is my 3rd year with mine. Maybe it’s my poor memory but it sure seems like mine looks worse than last year. Spring ia here for our locale so I’m going to repot it in a slightly larger pot this coming week as I take it outside. It’s down to about 10% leaves. Yikes.
I repotted mine last spring. I need to give it a bath-it’s dusty and likely has some sort of bug-I see some slick looking stuff.
