In My Seed Box For 2023 - Cabbages & Spring Greens


In the past I have tried to find different varieties that had different sow grow and harvest times so that I could try grow and harvest for as long as possible. Plans for 2020 didn't pan out due to shielding my wife against Covid-19, and 2021 was not a lot better, so I made the magic happen in 2022, and I will be looking to repeat the success in 2023. 

Cabbage Seeds if kept in ideal conditions last 4 - 7 years, so I will expect a reduced germination rate when I sow the remainder of 2018 seed stock.

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 Marshalls Spring Green Seeds - Greensleeves.  

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

Protect from Cabbage White Butterfly with netting.

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 in 2023

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.

Cultivation Advice Cabbage Durham Early Spring Greens

  • Sow between Mid-July and Sep thinly in trays or directly to seed drills using 2-3 seeds every 12 in.
  • Planting depth 1/8 inch. When seedlings are 1 inch tall thin to one plant every 12-18 inches or plant out tray seedlings to growing location.
  • Best sown / located in full sun where no cabbage was grown the year before.
  • Keep weed free and protect against pests, especially pigeons over-winter.
  • Harvest alternative plants from Feb as spring greens and mature heads from early Apr.

The Greensleeves Spring Green seeds are the right candidates for trying again in my AGRALAN Compact Plug Plant Trainer.
