Going through my extensive cabbage seed collection and looking for something that looks like it may provide the Spring Greens that SWMBO loves, I finally had a search and found a couple of varieties that are sold as Spring Greens. I purchased a pack of Spring Green Seeds - Greensleeves from Marshalls for £1.99 incl. P&P
Sow Outdoors: April-May or July-August. Sow thinly ½in (1cm) deep in a seed bed or clean module trays of firm pre watered compost. Keep soil moist at all times.
Plant Out: 6in (15cm) apart, in rows 12in (30cm) apart when plant has 3-4 true leaves.
Harvest: October-November or April-May

Looking at the sowing instructions in particular the spacing and rows, I thought about the planting membrane sheets that I already have and decided to create a new one specifically for the Spring Greens
So the idea is to give a 300mm exclusion zone around the perimeter so that hopefully it keeps the spring greens away from the netted hoops that will go over the bed. working on the basis of 150mm centres and 300mm between rows, I decided to stagger alternate rows so there is a little more space between plants but they are still dense enough to assist in growing as spring greens.
I've also bought a pack of Cabbage Durham Early Spring Green Seeds for £1.39 incl. P&P from Premier Seeds Direct for an Autumn sowing.
This variety is a well-known and very reliable compact spring cabbage producing dark green pointed firm heads of medium size, good flavour and texture. Suited for high density growing for spring greens harvesting from Feb onwards and Apr for fully mature heads. Autumn sowing variety.

I think that the Greensleeves Spring Geen seeds are the right candidates for trying out my AGRALAN Compact Plug Plant Trainer when they arrive.
