Hi There,
I bought this citrus tree from rona last year. It had a couple of lemon on it. Now it has nothing.
How am I supposed to take care of it to make it give lemons this year?
You need a high-nitrogen liquid or granular fertilizer. Liquid fertilizers are easiest to use on citrus trees that grow in containers. Do not water your tree too much! this is one of the keys to keep the fruit on the tree...
Good luck :)
