It's easy to grow. If you do plant some I recommend ordering from an online grower. That;s what I did the first time and it's grown really well. Over the years I tried buying some Walmart aspargus of different varieties, its been dried out, most hasn't grown.
When I planted mine the ground was to hard to dig, and I didn't have a roto tiller, so I put the crowns on the ground and covered them with about four inches of potting soil, watered them every day. It wasn't long before the rooted and grew. After about three years it was ready to harvest.
It's recommended to NOT cut them if they are 1/8 inch or smaller. I leave a lot that are 1/4 inch to make sure they thrive. If you want to give your pee a nice fresh smell, eat lots of Asparagus.
