💡 Growing Tips for Fennel

Don't plant near dill -- they cross-pollinate. Hill soil around bulb as it develops. Wait until soil warms to at least 15°C before transplanting outdoors — cold soil stunts growth and can invite root rot. Aim for about 2.5 cm of water per week, adjusting for rainfall. Organic mulch around the base helps maintain even moisture.

Frost tolerance: Fennel is NOT frost tolerant — wait until after the last frost in Pattaya.
