Things to know

White asparagus is very popular and no sooner has the season begun, than it feels for all asparagus fans as if it is also directly over again. Asparagus begins to grow when the temperature of the soil is 12 ° C warm.  Depending on the climate, in Switzerland, this is from mid to late April. The white color comes from the fact that the white asparagus grows under the ground. The end date of the asparagus harvest is always fixed, with June 24 every year on St. John’s Day. The reason for this is that the asparagus plants, which are not sown annually, need time to generate before the first frost occurs. St. John’s Day to the first frost is at least 100 days, which is enough time.
