you need to dig plenty of manure or compost into the ground as you would a runner bean trench,you can sow some next month and over winter them in a frost free greenhouse,these will flower before your spring sown ones.
also you need good seeds of good plants.

Well i grew some this year for the first time from seed(mr fothergills) and they were blooming rubbish.I planted when they were strong plants and i've had about 5 flowers :oops:  They're still in the garden now but have no flowers on them. :roll: What did i do wrong? :cry:

Did you pinch the tips out when the seedlings got to  4 - 5 pairs of leaves  ?

Some sweet peas are known to not flower or very few if this is not done.

Yes i did pick off tips, soon i'm gonna grow some stocks and delphiniums from seed that wont need their tips taken off like fussy sweet peas
