Advise needed for meyer lemon tree that does not flower
I have a 7-8 year old Meyer lemon tree that used to flower and produce lemons every year, however it has not done so for the past 3 or so years. The tree is kept in my greenhouse during the winter months and then when the weather breaks here in NJ, it is placed outdoors. In the past I had a lot of leaf drop in the winter, however this year I kept the leaves moist 2-3 times per week using a hand sprayer and lost very few leaves. I am careful not to overwater the tree and it has grown quite nicely over the years and I repotted a few years ago as I felt that it had outgrown the previous pot. Last year I cut back all the suckers as I thought that too much energy was going to the new branches. Any suggestions?
