2022 - What's made you happy today

In the last 5 years or so I must have put in at least 10 asparagus plants on and off. Not expensive ones but Home Bargains 99p sort. Probably because I was too tight to buy from a proper merchant only 2 plants have survived and I'd given up on ever having a single decent spear. My happy today is discovering one plant is throwing up 4 or 5 thumb thick spears. Can I cut all of them or do I need to leave some for the plant?

I think you can cut everything for a few weeks, 6 for mature plants, and then let everything grow. I tried leaving the spindly stuff and the plant just went cheers, and stopped growing new spears.
