Question
I have 2 dwarf Meyer lemons trees and one Bares lime growing in the same area and planted at the same time.  The 2 lemon trees are prolific and produce an ample crop of lemons.  We have had only one lime and it was on the tree when we planted it.  Do I need to have 2 trees to pollinate?  There are no flowers, so I can't hand pollinate and they are outdoors with lots of bees.

Thanks.

Hi Jayne,
Thanx for your question.  Most fruit trees will fruit better if there is another like tree nearby.  I had a solitaire lime tree and it would produce 2 or 3 fruit a year (it was a dwarf).  If there are no flowers, there can be no fruit.  Potted trees tend to get rootbound and this inhibition and result in no blooming and no fruiting.  Is your lime tree in a pot, what is the size of the pot and how long has it been in the pot?  You may need to prune the roots to reinvigorate the tree.  I had a friend who had a 6 foot tall lemon tree for 15 years in the kitchen.  It bloomed for years and then stopped blooming but still looked great.  It never, in 15 years, set fruit but it was growing in a pot about the size of a large dutch oven.  If you can supply me with the requested information that might help but I think the tree is root bound.  If it's not blooming, it may need some phosphorus.  I hope this helps.
