I have a large lemon tree planted in an eighteen inch terracotta pot.last year the ants built a nest under the tree in the pot and the tree was covered in ants so I went to war on the ants and killed the ants with a liquid ant killer.
this year all the leaves have turned a very pale yellow/green and have small pale yellow blotches all over them. the tree has flowered but the fruits that set have turned black and fallen off when they were about the size of a pea.
The poor tree is not happy, I have had this tree for more than ten years , and I have fed it each summer and had loads of lovely lemons in the past, What should I do ?
