Thorns on Orange Tree
So I've been reading many posts throughout these forums, so much to learn! One point that has been made is that orange trees don't have thorns and if they do, the rootstock is taking over. Is that correct?
I have a navel orange tree, over 10 years old, it was planted in the ground when we bought the house. It's about 10' tall and over the years has given me some oranges not many, but all incredibly sweet. Last year there was an abundance of oranges, but all shriveled and dry inside. I attribute it to lack of water as we were having watering issues.
Now this year, I've been diligent in fertilizing and watering it (along with my 5 other citrus trees thanks to this forum!) and it has set quite a few fruits. However, there are about 3 branches in this tree that have LARGE thorns on them. Is my tree doomed? Do I remove those branches or leave them alone? I don't want to lose my beautiful, well established tree!
What do you experts recommend?
