I need help with my Meyer Lemon tree!
My Meyer Lemon tree has been struggling lately, and I don't know what the problem is. Please help!
Just a little background on my tree:
I've had it for less than a year; I got it back in September from a nursery. It was doing fine for a few months and had many flower buds on it. Within the last month or two, it started to look really sickly. On closer inspection, I noticed it had a spider mite problem. After doing some browsing and searching online, I went to the store and bought some Insecticidal Soap. I had read on other sites and forums to treat it approximately every 7-9 days for a few weeks to kill the adult spider mites and also subsequent adults that were hanging out as larvae.
I've done that for 3 weeks now, and I haven't seen any signs of spider mites. However, my tree still doesn't look great. I also read that spider mites don't like air circulation, so from time to time I'll turn on a fan from a distance to get some air circulation in the room.
I water my plant every 7-9 days, and this last week I put some fertilizer that was high in nitrogen. Was it too soon to fertilize it since it's been stressed by spider mites?
It sits by a south-facing window and gets plenty of sunlight (but I try not to let it have too much direct sun)
The leaves continue to turn yellow and fall off. I can't tell that the leaves fall off in any sort of order (ie, older vs. newer leaves).
What am I doing wrong? Please help! I don't want it to die. :(
