Perhaps your orange tree is in need of more nutrients. At this time of year your tree would benefit from an application either Thrive Liquid Plant Food For Citrus. Both of these products will be able to provide the necessary nutrients that citrus need to produce good healthy growth and an abundance of juicy fruit. Regular watering around the root zone and a good quality mulch on the ground will also benefit the tree. Hopefully you will soon see lots of lush growth appearing and be picking fruit next year.
