Satsuma tree leaf curls
I have a 5 year old, potted satsuma tree that was perfectly healthy and thriving. However i went on holiday for 9 days and left the tree with no care. When i returned the leaves are all dry and curled up. I have been watering it just like before but still the leaves remain dry and curled. The leaves are still green. What can i do to make it healthy again. I want to pick the leaves off, should i?
