Harvesting Commercially, whole plants are harvested mechanically. However, it usually is best for the home Gardener to harvest individual leaves. In this way, the plant is left in the Garden to regenerate more leaves for successive harvests. Consider regeneration when deciding between head and loose-leaf varieties. When a head variety matures, the whole head is harvested.
Pests Expect to find weed, insect and disease pests whenever a Garden is planted.
Remember, the leaves will be eaten, so use chemicals cautiously. Wait the required number of days before harvesting and wash leaves thoroughly before eating. Store chemicals properly and always use them according to label directions. Varieties Brussels sprouts . May be direct-seeded or transplanted.
