I managed to grow 3 seedlings into first year plants about 3 years back but didn't get any of them to grow to maturity

Still not sure if I over or under watered them but they didn't come back the 2nd spring

This year I bought 2 and have planted them in a large outdoor box as I reckon the veg beds aren't enough to dedicate that space for a decade - the single shoot has grown and I'm watering away, so just hoping I don't mess up again as I really would like to try homegrown asparagus and something that grows back itself for 20 years would be a decent investment

Whether it'll like a box or not I don't know

If you get tips I'll be reading them, and if you have success please pass on your own tips
