My asparagus bed is about 6 yes. old and now I am seeing very thin spears along with nice healthy ones. What is going on?
Lawrence County Missouri
The problem is usually cultural. Be sure to not harvest too many spears in any given year. Also make sure to leave the ferns growing healthy throughout the growing season. Also be sure to add fertilizer and lime regularly.
