All new growth on some of my citrus tree are suckers
Two of my citrus trees seem to be reverting back to suckers. All new growth has flat, broad & misshapen branches with large leaves and thorns. This is happening above the graft line. I have pruned them all back on one tree but that does not leave much of the tree. I took over the care of these trees 2 months ago and immediately saw they had problems. Reducing the watering, and a nitrogen feed.
Thank you for your reply. We live on Crete & not sure if such an office excist. I will try to find out though. We have advise from our local agriculture store he told me to keep removing all the suckers, feed regularly, reduce the water and the trees may recover in 2 years time.We have noticed several more trees in the area with the same problem, but no common denominater, ie watering,feeding as they belong to different people.
I would suggest contacting your local agricultural extension office and asking their citrus specialist. If this growth was coming from below the graft, it would be apparent that you are getting rootstock suckers.
