💡 Growing Tips for Jalapeno

Start indoors 8 weeks before last frost. Red jalapenos are riper and hotter than green. Wait until soil warms to at least 22°C before transplanting outdoors — cold soil stunts growth and can invite root rot. Water steadily but avoid soggy soil. A 5-cm layer of organic mulch helps balance moisture and suppress weeds.

Frost tolerance: Jalapeno is NOT frost tolerant — wait until after the last frost in Siem Reap.
