I tend not to track the more personal things on this site and growing vegetable is one of those, but I take exception here as this is a first and seems a delicate operation. They're delivered in a cardboard box 33 x 24 x 2(mm), surrounded by damp newspaper and a biodegradable plastic bag.
It seems to hot to put them out now at 12 Noon BST so will wait till the evening. The plant spacing is recommended as 4 to 6 inches.
Some 120 planted out as the sun was setting in 4 rows of approx 25 plants with 6" spacing and 9" between rows.
