I live in Southern California and it seems like everybody has some type of citrus tree in their yard. When we moved here about 30 years ago, our yard had a small gnarly crabapple tree, two lemon trees, and an apricot tree.
We removed the crabapple - it was not in good shape.
The apricot was a lovely smaller tree with nice shade. The fruit was small but useable - when it produced. Also was a squirrel and ant magnet. Squirrels would take one bite out of the fruit, then throw it on the ground. Unfortunately, the tree was quit old and died maybe 15 years ago so we removed it.
The lemons are spectacular - Meyer lemons as far as we can tell. VERY bushy and thorny but the lemons are exquisite. Lots of bees and hummingbirds. Unfortunately, recent health issues have kept me from cooking and baking, so now much of the fruit goes to waste. If my husband didn’t work from home, he could take some to the office, as I used to do. It was definitely a treat to dash outside and pick a few when I made lemon curd, marinated chicken, or roasted a salmon.
Our neighbors have a huge avocado tree which also attracts squirrels - one bite and they throw it on our driveway.
Anyway - fruit trees do need attention with pruning and picking, and keeping critters away.
