agapanthus advice

It's cooler this year, around 28/30C and yes, it's a longer growing season. Very dry though.
Attaboy! Three years from now we expect to see some wonderful photos

 

Hi all
New to this forum so hopefully this is correct as followed the set up instructions
I know this question seems a bit premature as we are only in May.

I have 3 evergreen agapanthus that will require winter protection. They are in large pots and I do not have a greenhouse. Could anybody kindly advise on how to protect them in the winter months
I have read that I should position them a close to my house wall to allow for any radiant heat
Also to cover the pot with hessian and wrap good quality fleece around the plant
Any advice will gladly received
