Stages of Growth
Cabbage plants go through the following stages of growth:
- Germination: The seeds germinate and the seedlings emerge from the soil.
- Vegetative growth: The seedlings grow leaves and roots.
- Head formation: The leaves begin to wrap around each other to form a head.
- Maturity: The head is fully formed and ready to harvest.
Common Pests and Diseases
Cabbage plants can be susceptible to a number of pests and diseases, including:
- Cabbage loopers: These caterpillars can damage the leaves of cabbage plants.
