Lemon tree with no lemons
A friend has a lemon tree, about 4 years old, in the ground and she hasn't gotten any lemons off of it. The tree is located in the small patio area of her condo. It gets half day sun I'm sure, I'm sure she waters and fertilizes it but I haven't asked specifics on that.
I saw the tree yesterday and it looks healthy, not vibrant green, but many branches and decent looking leaves.
I wonder if it's the soil; being a condo it's not easy to add good soil ingredients over the years as with a regular garden.
