Lemon tree in Missouri? Is it in a greenhouse? A friend in Maine has a greenhouse with orange, lemon and lime trees.

No. I have it outdoors from spring, summer, and fall. Then I bring it in and put it in front of the patio door which faces southwest.

It often puts on flowers in December, and the smell is wonderful.

About 15 years ago a grapefruit rind left in a bowl over a weekend had a sprouting seed. We planted it in a pot. It is 5 feet tall today. In Denver. It comes inside at the first hint of frost then goes back out when we plant the tomato and watermelon plants.

Colorado's front range is the greenest in 20 years. We have a bumper crop of watermelons. They are third generation with seeds from last years melons. The tomatos are fifth generation from last years seeds.
