A very well known and trusted variety, Cabbage Primo II produces solid ball head cabbage.
Easy and productive, Primo II is a splendid cabbage, it forms solid round green cabbages. It can also be grown at a higher density.
When sown from March onwards they are ready to cut in summer though early autumn. To ensure a steady supply just sow a few seeds every week or so.
The round, medium sized heads are produced on neat compact plants, and are delicious steamed, raw in salads or used for delicious, homemade coleslaw.
Cabbage "Primo II" is an old and trusted variety, We haven't yet found a date - but the photograph above shows Reginald Clarke on his allotment at Eynsham, Whitney in Oxfordshire, with the pride of his life, his giant Primo cabbage measuring over three feet across. It is dated 1954
Prepare the site:
All brassica crops grow best in partial-shade, in firm, fertile, free-draining soil. Start digging over your soil as soon as you can brave the elements. Remove any stones you find and work in plenty of well-rotted manure or compost. Tread on the soil to remove air pockets and to make the surface firm. Brassicas will fail if the soil is too acidic; add lime to the soil if necessary, aiming for a pH of 6.5 to 7.5.
Sowing: Sow successionally from March to July
Nearly all brassicas should be planted in a seedbed or in modules under glass and then transferred. Seeds should be sown thinly, as this reduces the amount of future thinning necessary and potential risk from pests.
Sow seeds 1.25cm (½in) deep and space 15 to 20cm (6 to 8in) between rows.
Once the seeds have germinated, thin the seedlings to 7.5cm (3in) between each plant. After germination, seedlings will often be ‘leggy’, so plant them as deep as possible to really anchor them into the soil.
Cabbage seedlings are ready for transplanting when they are between 6 and 8cm high (2½ to 3in). Water the day before moving, and keep well-watered until established. Plant firmly, close together for small heads and wider apart for larger cabbages, around 30 to 45cm (12 to 18in) apart.

Clear away any yellow leaves. Feed the plants as they near maturity with a foliar feed.
Harvest: June to September.
Earliest heads can be cut, leaving the stump in the ground to produce a second crop of small leafy heads.
Brassicas are affected by a wide range of pests and diseases, especially the fungal disease, club root. The roots become stubby and swollen and can develop wet rot, while leaves become yellow and wilt, causing severe stunting of growth. Remove any infected plants from the ground and destroy. Make sure the soil is adequately limed and well drained.
Rotate your crops annually to avoid disease. Don't grow brassicas on the same plot more often than one year in three, as moving the crop helps avoid the build up of soil pests and diseases
