Hi all. We moved into a house last year which had this tree in the garden. It looked in poor condition and I wasn't sure if it was dead. However, I watered it well over the last summer and fed it with miracle grow and it showed some new green growth. The photo is how it looks just now. Can anyone tell me if it's worth persevering with and if so, what is the best way to save it? It is still more dead than alive to look at it.
