Overwatering, nutrient difficency, or shock?
I recently purchased a 3 year old dwarf improved meyer lemon from Four Winds Growers. It arrived a little beat up but after planting in a 12inch diameter, 5 gallon pot, it perked right up. The soil I used was a mix of standard top soil, some stuff called Bark and Steer (compost with larger bark pieces), and the wood shavings that the plant arrived in. I watered when I put it in the pot and it looked great for a week.
I moved it outside and watered again (this is about a week after the first watering). I did not gradually move it (after reading a lot of these posts, I probably should have). After being outside for 2 days, I realized the weather was going to turn and we were going to have a night with temps in the 20s so I picked it up and put it inside not wanting it to freeze. It has since been in a spot with windows facing south and east.
It looks very sad! New leaves are drooping, older leaves are turning yellow and starting to fall off, and the one beautiful bud has lost it's petals :(.
I have not watered it again, worrying that it is overwatered or not draining well, I haven't given it any fertilizer yet as instructions from Four Winds said to wait a couple weeks. I know I need to do something, but I'm not sure what the best course of action is and refer to all of you as experts! Please let me know any thoughts.
