Local Harvest Gardening

A question for Dan or Jack and the group. In the planning the garden videos taken in the green house I think I see citrus trees behind you. I’ve tried growing a lemon tree in my green house and failed miserably twice. With your help I’d like to try again. Can you please share some recommendations and growing tips?.
Thank you.

We'll give tips for growing citrus under the topic lemons and limes.
