Wintergreen Offenham 3 cabbage has proven itself as an excellent variety for both spring greens, from February onwards and for early season cabbages. It hearts up in April.
Large well-filled dark green heads produce conical leaves on strong plants; the leaves are well flavoured and sweet. The plants are uniform with a heavy crop at first cut and are not prone to bolting.
It is a very popular variety and an ideal tasty vegetable when little else is available.
Cabbage can be produced throughout the year, providing growers with a continuous supply. Extremely hardy, these faster-maturing spring greens are ideal for utilising redundant polytunnel or glasshouse space over the winter months.
Awarded the Royal Horticultural Societys Award of Garden Merit (RHS AGM).
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 6.5-7.5.
Sowing: Sow successionally from February 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 12mm (½in) deep and space 15 to 20cm (6-8in) 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 30-45cm (12 to 18in) apart.
Clear away any yellow leaves. Feed the plants as they near maturity with a foliar feed.
June to August (through to October)
Earliest heads can be cut, leaving the stump in the ground to produce a second crop of small leafy heads.
Suitable for the vegetable garden, allotments and containers.
Be prepared to water well and supplement feed with high-potash feed during season. Regular feeding is recommended.
