Cauliflower roots are considered shallow rooting, typically reaching a depth of 12 to 18 inches.
According to the information provided by Eartheasy on Soil Depth Requirements for Common Garden Vegetables, cauliflower falls into the "Shallow Rooting" category.
Here's a breakdown based on the reference:
Root Depth Categories for Garden Vegetables
| Rooting Depth | Depth Range | Examples |
|---|---|---|
| Shallow | 12" - 18" | Cauliflower, Celery, Chinese cabbage, Endive |
| Medium | 18" - 24" | Cantaloupe, Carrots, Chard, Cucumber |
| Deep | 24" - 36"+ | Okra, Parsnips, Pumpkins, Rhubarb |
This classification suggests that while cauliflower requires adequate soil depth for healthy growth, its root system does not penetrate as deeply into the soil as vegetables like carrots or parsnips. Providing a soil depth of at least 12 to 18 inches is sufficient to support the root development of cauliflower.
