Recommended plant density is 30-40 buds per plant, and pruning of canes to 6-8 buds for optimal growth and yield. It is also important to regulate cluster numbers to maintain berry quality.
Comet has good transportability and can retain its market quality during storage until February. Due to its large, attractive berries, as well as resistance to pests and diseases, this variety is popular among gardeners and table grape producers.
