I bought my lemon tree in April of 08 and as soon as I got it home i repotted it with miracle grow. I also got fertilizer the retailer suggested for it, and I use it about once a month. It started off well and then around June the leaves started turning yellow and dieing and at that time it was getting about 10 hrs of sun and watered about 1 or 2 times a week... We went on vacation about a month ago and when we got back just about all the leaves were gone.. I live in Tx and for the past couple of weeks we have been getting 100+ Degree weather with little rain... I asked my Grandma who has a green thumb, and she said I should put it where it gets sunlight in the morning and shade during the hot part of the days and water it just about every day or every other day.. So I did so and gets maybe 4 hrs of morning sun.. Since then it started growing leaves again but they have a light green color and are very droopy. Any suggestions on how to make it heathy again I would really appreciate.
