Frost triggers modifications in plant chemistry that result in sweeter style, which implies winter harvests usually style higher than summer time ones.

• Sure crops solely succeed when temperature thresholds keep above particular limits — Onions develop reliably in winter buildings provided that temperatures keep above 20 levels F, which is why the article recommends planting units as a substitute of seeds.
