When life gives you lemon pips... Answered
A friend just brought us back a lemon she picked (with permission) from a grove in a convent garden in Rome. It was very tasty, and had five pips in it.
What is the best way to grow these pips on into a new bush or tree?
I don't have a greenhouse, but I do have windowsills. I eventually plan for the bush / tree to end up in a large pot.
(I know I could google it, but do you happen to know whether lemon trees have gender? In other words, would I need two trees to get fruit?)
