Nutrient demand by stage
NPK ratios are relative weights. EC targets shift through the plant's life.
| Stage | N | P | K | EC (mS/cm) |
|---|---|---|---|---|
| seedling | 2 | 1 | 1 | 0.8 |
| vegetative | 2 | 1 | 2 | 1.4 |
Aquaponics suitability
Compatible
Fish waste provides enough nitrogen for healthy growth. Supplemental potassium, calcium, and iron may still be needed depending on fish stocking density.
Care notes
An easy, low-maintenance perennial herb for cool conditions. EC 1.0-1.6 mS/cm. pH 6.0-7.5. Temperature: 10–25°C (cool-season; bolts and declines in sustained heat). Moderate light (DLI 14-22 mol/m2/day). Any hydroponic system works. The plant is small (20–40 cm) and compact. Harvest young leaves for their cucumber-like flavour and add them to salads, float them on cold drinks in place of cucumber, or use them as a garnish. The evergreen habit allows winter harvesting, a useful trait when most salad herbs are dormant. Propagate by seed or by dividing established clumps, remove flower stems to keep leaf production going, and note that the plant self-seeds outdoors. Salad burnet is a niche herb with limited commercial demand but real culinary value, adding a fresh cucumber note without the water content of actual cucumber.
