Citrus Issues

It appears that there are a few things going on here: 1 – Your tree is competing with the weedy grass at its base for water and nutrients. We suggest you remove all weeds. 2 – The lack of foliage could be attributed to a number of things. It could be under watering, lack of nutrients or a chewing insect. You might want to review your watering practices.
