Hi , I am about to construct a cold frame, and would appreciate any
advice,
on construction ,a nd location in the garden i e :
north , south , east or west facing aspect .

thanks in anticipation

I prefer frames constructed with one of the double-skinned horticultural
plastics, as obtainable from Plastics by Post (or is it "by mail"?) They
make lightweight, easily transportable frames. The material can be cut with
a Stanley knife and assembled by making small holes and "sewing" the parts
together with fishing nylon. They provide good thermal insulation, as a
result of the double wall. The only slight drawback is that they are so
light that they have to be weighted down. I do this by building them with
triangular gussets (which also keeps them square) in the bottom and making
sure that there are always some pots or seedpans standing on the gussets.
If you are too lazy to assemble them with sewn string, you can use duck tape
instead. That lasts for around two seasons. I make both frames and cloches
like this.

Frames for rooting summer cuttings are best sited such as to be out of reach
of direct sunlight. Frames for overwintering this and that or for seed
raising are best kept in full sunlight.
