Hi My lime tree appears dead. There are no new buds and no leaves at all. Many of the branches I think are dead. The trunk of the tree is still green!, should I cut off what I think is dead and pot it up in citrus soil and hope for the best? The tree was a gift of £80 I really love it and I went it to live
Citrus need full sun. If this is indoors, then it will need at least 200 watts of horticultural grade lighting to thrive. Feeding in container will consist of citrus fertilizer, dolomitic lime, and iron sulfate 2 or 3 times per year.
