For some time (years) I have had a Lemon Tree I planted. When the low temperature is below 32 degrees I protect. This is a Meyer Lemon and is great taste lemons. Plus very useful in variety recipes. The tree is about 3 1/2 to 4 feet high. This year we have picked 140+ lemons. I understand some in the are have had difficulty. And dI am not very smart. These are great!
