Answer
Dear Lynda, The big question is where are you growing it and what is the climate like in your area.  Generally you have to grow a lemon tree outdoors because they require a lot of sun.  You can achieve the same effect by giving them a bright grow light indoors, but then you have another problem in pollination.  Lemon trees are generally pollinated by bees, so they really should be outdoors for that.  Can't get it outdoors because your climate is too cool?  No problem.  Take a blossom or two and remove it from the tree, then rub the flowers against the stigma (green sticky part sticking up out of flower) of other flowers to transfer pollen.  You may have to use several flowers and you may not always be successful, but it does work.  Also, all the flowers in a cluster won't make lemons, usually only one or two.  They do like to be fed regularly so give them a fertilizer with a high middle number.  Let me know if this helps or if you need more help.  Good luck, Melissa
