Hi. The tree was preexisting on this property. Fruit was rather thick skinned and very dry with not a lot of juice. Also has has fruit fly until particularly bad frosts one season followed by a brutal summer, which has seemed to knock them out. Last summer knocked the tree about a lot and we got no fruit whatsoever despite watering regularly. We aggresively cut it back and thinned it out this Autumn. The Winter crop was smaller, but the fruit was much juicier. Now, the west side of the tree has yellowing leaves and some leaf fall. I did accidently flood it a few weeks ago, but that was well after the leaves started to yellow. There is grass right up to the tree. Please help, it may not survive another hot summer of 40’s if we can’t build it up now.

All citrus trees are grafted and they usually only live or perform well for around 15 years. This is due to graft incompatibility. Your’s is probably past it, so get one of the new seedless Eureka lemon trees. Don
