Hi, I recently got a dwarf Eureka lemon tree that is potted in a planter. It has not been doing well since it got transplanted. The leaves are turning yellow and falling off. There's a lot of conditions that may be adversely affecting the tree, so I'm not sure which to try and treat. I'm going to list out as much info as I can below and post pictures of the tree. Any help would be greatly appreciated. Got tree a week and a half before transplanting. Tree seemed healthy while it was in original pot being watered by sprinkler system. Transplanted into planter using citrus potting soil with fertilizer premixed. When transplanting, a friend that was helping me was fairly violent about shaking apart roots. I read that you aren't supposed to mess with them when transplanting, so I'm worried. The root system was not root bound and did not show signs of rot, but it did appear to be fairly small. I transplanted it with a bit if the root ball above the top of soil. The tree is in Southern CA and gets morning and afternoon sun. I originally set it up to be watered with a drip irrigation system that was giving it 1.5 gallons of water a day. I've since switched to deep watering with a hose twice a week. There are 4 drainage holes in the planter that are a inch wide. The planter was new and hasn't been used for any thing before.
