As an owner of an apple tree: that's great for about two months, but I don't have commercial quantities of cold storage.

We used to have a lemon tree. When it was producing, 80% of it went to waste. When it wasn't producing, we had to buy.

It was still worth it, though. It required very little maintenance (pruning once a year, replace the batteries on the auto-irrigation system a couple times a year), so it was basically free.
