If you post me your cow , I'll send you five magic beans that will give you 24 inch long runner beans that only turn stringy when the weather turns colder just before the first frosts in Autumn .
PM me your address ,
soak the beans for 24 hrs and sow 1 & 1/2 in a well damp compost , keep it moist & in the warmth but not sopping wet .
Meanwhile dig a hole about 18 inche deep by 18 inches acros and fill the bottom foot with well rotted manure and put the top soil back on it . You'll have the beans up ready to plant out by about 6 June
Runner beans just love a hot moist well rotted manure bed .
Ps forget the cow the freezer is still full of beans I send you the beans anyway .
