Meyers Lemon Sap?
Newbie here so please be gentle.
Can anyone tell me what this is on my lemon tree? The tree(bush) is about 1 1/2yrs old. It is sticky like sap. The tree has sprouted flowers that turned into little lemons that fell off. I did get one lemon that grew to about the size of a grape then one day I walked into the room and the little guy was on the ground. Talk about heart breaking. It has gone through cycles of losing all of its leaves and then coming back with aggressive growth. I water it when I think it might be drying out and I add fertilizer once a month. Any help would be much appreciated.
