Question about harvesting asparagus
I planted asparagus last year and, as instructed, did not harvest it. This year, I just noticed that I have multiple plants, but they've already started to fern or seed. I cut some of them, but they don't snap easily. I'm not sure if they've grown faster because of the heat? I read somewhere not to let them fern because it would encourage asparagus bugs of some sort. But, I just threw the harvested spears into the compost pile because they're tough and not snappy. What have I done wrong?
Thanks in advance.
