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

Spring bulb planting

Spring-planted bulbous flowers are annual flowers, most of which are short-lived and are generally planted in spring and bloom in autumn. Varieties of bulbous flowers planted in spring include canna, amaryllis, etc. They have large, colorful flowers, good plant shape, and are easy to cultivate. The best temperature for open field cultivation is between 13-17 degrees. Generally, fertile, loose, well-drained sandy loam or fertile clay soil is chosen. The growth habits of spring-planted bulbous flowers generally prefer a warm and well-lit growing environment. They are not cold-resistant and require higher temperatures during the growing period. Therefore, they are generally planted in spring. They will bloom in summer. When the weather turns cold in autumn, the above-ground parts will turn yellow and the plants will gradually enter a dormant period. It should be noted that underground bulbs are not cold-resistant. In cold climates, they need to be carefully dug out and stored well to ensure safe wintering. In the north, underground tubers generally need to be dug out before frost and then stored in an environment of around 5°C.

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.
