Q.How Long Will My Tangerine Tree Produce Fruit?
Do I need to water weekly once no more fruit is on the tree? I had fruit on my tree Dec.2021 & Jan.2022. The tree was on the property that I bought in Oct. 2021.

Yes, if you aren't getting regular rainfall you need to irrigate the tree, especially if it looks like a young tree. A more mature tree can go longer without water.
