I start mine off in small cell trays/ little pots. they can then be planted out when bigger and the weather is better [hopefully!]

Thankyou. That way I know if they are germinating anyway.

Hi Granny,
The seed pkt info is only a guide as to when to sow,
if you think about it these seeds are sold all over the uk and the weather is colder for longer in some places but not in others,

Having said this, seed pkt info is very good ref how to bring the seeds on from sowing to planting, ie all the info you could need,
Its your area, you'll see for yourself what the weathers like and infact you'll know better than the seed people.
