Appearance
Brassica plants come in a variety of sizes and shapes, but they all have similar characteristics. They have large, green, lobed leaves and produce large clusters of flowers in shades of yellow, white, and purple. The flowers eventually give way to fruits, which are often edible.

- Soil: Brassicas prefer well-draining soil with a pH between 6.0 and 7.5.
- Sunlight: These plants need full sun for optimal growth.
- Hardiness Zones: Brassicas are hardy in zones 2-11.
Common Pests & Diseases
Brassica plants can be susceptible to a variety of pests and diseases, including:
- Cabbage loopers: These caterpillars can cause extensive damage to leaves.
- Cabbage worms: Similar to cabbage loopers, these worms feed on leaves and can cause significant damage.
- Aphids: These small insects suck sap from leaves and can cause stunted growth and yellowing foliage.
- Clubroot: This fungal disease can cause stunted growth and yellowing leaves. It is most common in wet soil.
- Black rot: This bacterial disease causes yellowing and wilting of leaves and can eventually kill the plant.
