My poor citrus trees are struggling. Planted last winter got eaten by scale then by snails then bashed by winds some of them are surprisingly good but a couple particularly my orange are very sad. My orange has only 2 leaves. The sick ones are trying to put out new buds. I am wondering what is the best thing to do to help. I have seasol & my home made horse manure tea. Any suggestions which would be best to use & how often. Very sandy soil so I am watering once a week. Any other suggestions to help my my little citrus they look so sad.
