asperagus fronds are turning yellow
Is it normal for the ferns to turn yellow this early? This is my second year. Only did a very little harvest this year, for about a week then I let everything grow into ferns. I have been noticing that they are turning yellow. I give them water and I fertilized them early in spring then again in July. The fern is so thick and in the middle it is very yellow. The outside edge of the fern is still green and still getting thicker. Any advice would be appreciated.
