This is my second meyer lemon tree (my first one died) so I'm desperate for some advice. I purchased this tree about a year ago and it had been healthy and producing fruit for the first year. This past few months most of the leaves have started curling and turning yellow. Now the majority of the leaves are turning yellow and have brown spots or lesions on them and then fall off. See pictures attached... We had a very rainy winter so I haven't watered the plant much and try not to water until the water meter reads near dry. The plant is in the bay area of california (menlo park) so gets lots of warm sun. I feed the plant with EBStone Citrus food every month and supplement with fish and seaweed emulsion during watering. We recently replaced the first 2 inches of dirt with compost thinking that this was a good for the plant. Could this be the reason for the necrosis on the leaves? Should we repot? Is salt build up the cause? Mineral defficency? Any help would be greatly appreciated! Mary
