Growing Asparagus

I have purple asparagus, about a 7 year old bed. I read to only harvest spears that are larger than a pencil, but if I do that the smaller ones turn into "bushes" and hide the larger spears. Is this the correct way to harvest and grow? Question 2: I read to only harvest them for a certain number of weeks and then when they start getting pencil thin, to stop harvesting. but this seems like such a short harvest season, and the plants still want to produce. It is as if my asparagus bed is bushy more than it is in the productive mode. Is this correct? Can I continue to harvest longer? Question 3: Can I plant the poisonous red balls and they will grow into new plants? I thought my old plants would reproduce, but my bed seems to be about the same annually. I just don't feel like a confident grower, and the sources I read don't seem to provide information specific enough for my needs. thank you

Asparagus needs two things.1. It needs some ferns left at the end of growing season to feed and build the nutrient storage in the crown for the next season. 2. They also need fertiliser in the growing season. Here is what I do. I cut the ferns off end of winter, give a good watering, a good fertilising, then 6
