The difference between autumn-planted bulbs and spring-planted bulbs

Spring bulb planting

Autumn Planting Bulbs

Autumn-planted bulbous flowers are biennial flowers, most of which are long-day flowers and are usually planted in autumn to bloom in spring.

Autumn-planted bulbous flowers, such as hyacinths, are cold-resistant and heat-averse. They generally prefer a sunny, sheltered environment and can grow normally at temperatures above 8°C. They are highly cold-resistant and most can withstand temperatures as low as -14 degrees Celsius. The bulbs can even overwinter in the open, but they must avoid extreme heat. When the temperatures are high in summer, the above-ground parts gradually wither and the underground bulbs go into dormancy. For planting in autumn, it is best to choose loose, fertile, well-drained, slightly acidic sandy loam. As the temperature gradually drops in winter, it will stop growing and enter semi-dormancy. In the second year, the temperature will gradually rise, it will grow rapidly, and it will bloom in spring.
