When asparagus is grown outdoors, the long-awaited buds will appear in early spring after planting the seedlings. The important thing here is "fertilizer in early spring". When a few small asparagus shoots appear, apply 30g of chemical fertilizer or 50g of organic fertilizer per plant. Allows the buds that have emerged with nutrients from the storage scars to absorb nutrients from the absorbing roots. Asparagus should be fertilized 3 times: in early spring, in June after harvesting, and in autumn in September.
