You want a well dug spot, that you can easily keep weeds out of ( raised beds are good, even if only slightly, to keep the grass from creeping in). LOTS of organic material. LOTS! They like very deep soil-- so dig and loosen deeply before planting.
I've never seen plants for sale, only crowns ( roots) that are often ok to start cutting in 2 years, but 3 is better. If you start from seed, maybe another year beyond that. Whether you plant seeds or crowns, allow the plants to grow all season, die from frost, then cut back to soil level, mulch, repeat again the next year.
You can begin harvesting when the stalks are pencil width or bigger (which takes a couple years), cut them just at the soil line with a sharp knife, harvest new spears daily, and stop harvesting after 6 to 8 weeks. Allow the rest of the growing spears to grow to big, ferny plants, allow them to die after the frost, then you cut them to soil level,mulch and leave til next spring.
Patience, patience, patience when starting a new patch! Plan ahead-- it'll be there for 15 to 20 years or more-, so make sure it's in a workable space where you don't have future plans for. Patience!! Don't start cutting one year because you can't wait to try them, it'll have an effect on the hardiness of the patch overall.
We moved here just over 2 years ago and have an established patch, so we're lucky!! The unlucky part is it's in a BAD spot, in the middle of the grass, was all overgrown with weeds, and is going to be hard to sort out. I hope to move the crowns to a new bed, if not this fall, then next. I've also started plants from seed in a pot on my deck that will go into a new, raised bed, as soon as I get it built.

okay how do I start an asparagus patch? should it be by seed or little expensive plants? should I add anything to the soil where I want to grow it, composted manure, sand ect.?
