Q.Lime Bushes Not Producing
I have three lime bushes, but only one produces. They are within ten feet of each other. What can I do? They have been in the ground about 10 years and only the one produces fruit, abundantly. There are no blossoms on the other two.

There are a few things that could cause that. There may be a small micro-climate that is causing the other two trees to get less sun or heat than the blossom producing tree. Another reason may be that there is a source of nitrogen that is closer to the non-producing trees than the one that does produce. This would keep them from blooming.
Check to make sure that the two non-blooming trees are getting enough light and that the temps are the same (things like walls, buildings and fences can change the temperature of a very small location by 10-20 degrees F). Have the soil from the base of all three trees tested to make sure that they all are getting the same nutrients.
