Superslam is a new generation hybrid cabbage and is suitable for the late summer to early autumn sowing slot, very similar to that of Grandslam. The variety compares well to Grandslam and it is very well adapted to different climatic zones. Seedlings are very vigorous with good uniformity to ensure uniform harvesting. Superslam has round heads with a big frame and good head weight, making it perfectly suited to the hawker and the bagging market. This variety has been tested for an extended period in the different climatic zones and can be planted with great confidence.
Special varietal requirements:
Harvesting should be completed by September to avoid bolting. Cabbage Superslam is suited for January and February sowings in the Highveld. December sowings should be restricted to areas where late summer Black rot is unlikely to occur.
