Hi, Jo. I'm not sure whether you ever saw my response to your message under Introductions?
=> Welcome to The Helpful Gardener.
If you know your Sunset gardening zone, I can enter here the recommendations Sunset gives for your zone w/regard to figs and avocadoes.
In certain zones, Sunset recommends planting these trees in containers and bringing them indoors during the winter, but in others, planting in the ground is recommended.
Look forward to hearing from you, either on the forum or by pm. I can figure out your Sunset zone if you let me know your *nearest* large-ish town/city and county.
This info will come from Sunset's Western Garden Book
, designed to help gardeners in the western states and provinces: those which contain or are west of the Continental Divide. Many gardeners--including me--view the Sunset book as (almost) the Revealed Truth about plants and their needs.
USDA Zone 9, Sunset Zone 17
