Harvest and use

Pick baby leaves around 20-30 days from sowing or full plants near 45 days. Cut cleanly, wash and refrigerate. Use promptly for best texture. Seed saved from this F1 hybrid can vary and will not reliably reproduce Purple Gem.

Saving seed

Saved seed may vary from the purchased selection. Purple Gem is an F1 pak choi with purple-red oval leaves. Saved seed may segregate and is not guaranteed to reproduce the hybrid. For reliable repetition, use seed of the identified supplier selection. When saving seed for observation, keep compatible flowering varieties separated, let seed reach full maturity, dry it thoroughly and label its origin and year.

Common problems

Common concerns: Flea beetles, imported cabbageworm, cabbage loopers, aphids, slugs, root maggots, and clubroot risk where the pathogen is present. Management: Use rotation, insect netting before pests arrive, regular leaf inspection, sanitation, and well-drained soil. Do not plant the same brassica family repeatedly in one bed. Diagnosis note: Similar symptoms can have different causes. Compare plants of the same age, record weather and irrigation, and use local Extension or diagnostic support before applying a control.
