Why can't spring bulbs like tulips and daffodils grow well in warm zones?

Question

ForwardPlant Team · Accepted Answer

Spring bulbs such as tulips and daffodils require a chilling period to initiate proper root development and flowering. In warm zones, the soil temperatures often don't drop low enough or remain cold for a sufficient duration to satisfy this crucial physiological need. This lack of cold stratification prevents the embryonic flower within the bulb from maturing, leading to poor growth, a lack of blooms, or even the eventual decline of the bulb.
