That's cool to be able to grow oranges and lemons outside. They are definitely not on the growing agenda here in wet and windy Wales.
My ultimate dream still remains to grow bananas. Maybe with rising temps we might get there before I am 100.
Do you get any frosts there in winter?
No I can't imagine growing lemons or oranges outside in wales, in a greenhouse though, or indoors for lemons?
There is a slight risk of frost, it actually varies quite a bit depending on the specific microclimate, like one part of my land could be frosty on a few mornings, but where the trees are should be fine!
We have had a few lemons in the conservatory one year. But not managed oranges yet.
Good luck with fruitful harvests to come...
