Sweet peas

I fancied trying the earl grey ones - but i dont have a great track record with sweet peas. I hate picking them amd i think my spot may be a bit sunny/dry. They often go over quite quickly.
I'm sowing mine this week. Ive chosen a spencer variety - but will also sow a few home saved ones. I tend to keep mine in the greenhouse but i have read recently that an autumn sowing will do better in a cold frame... I may try a little bit of both to compare.

I always presprout mine on kitchen towel in a plastic tub - due to mice issues
