Watercress Needs to Grow With Its Roots Sitting in Actual Water
Watercress is genuinely an aquatic or semi-aquatic plant, and unlike every other leafy vegetable on this site, it needs its roots sitting in consistently moving or frequently refreshed water rather than typical potting soil, a fundamentally different growing method that a standard vegetable pot simply can't replicate well. Its peppery flavour is similar to nasturtium's and radish greens', but its growing requirement sets it apart entirely from those soil-grown plants, making it one of the more specialised, setup-dependent crops covered on this site rather than a simple pot-and-soil vegetable.

- ✂️ Harvest: Harvest outer leaves — never more than ⅓ at once. Pinch flower buds.
⚠️ Common Problems & Fixes
| Problem | Cause | Fix |
