You guys are so lucky. We love eating asparagus and I can only imagine the home grown stuff is 100 times better than the stuff from the store. I don’t know much about it though. We were just talking about it the other day actually. Is it something you can cut and it grows back like chives or something or is a one and done deal?
Find an out of the way area in your yard and plant some roots. I have about twenty feet of fence line with twenty plants that are well established after about 15 years. The roots will grow and expand each year a little. For the first three years and not yield much other than a few thin stalks. As the plants mature the stalks get thicker and taller and some will bear seed on the ferns. In the fall I pluck those seeds and plant them in shallow holes between the established plants, so the bed is much fuller now. I planted the seed along another garden border and have a nice bed there as well.
Cool wet springs like this will see it shoot up like crazy. Once cut the first time of the year the plants will shoot up more shoots. I have asparagus until late June when I stop cutting to let the plants grow. On average, I’ll need to cut about every four days if we have average rainfall.
If you are going to plant it, go to a greenhouse and get the roots, not those sold in plastic bags at Menards. Martha Washington is about the best variety to plant and is the easiest to find. Work the soil up by digging/tilling at least a foot deep. Plant the roots about 18″ apart and down about ten inches. It won’t take too long to see the toothpick thin stalks emerge. Just let them grow. Same for the following year. Keep the newly bedded plants damp if the weather turns dry, but not soaking wet. Asparagus likes at least 2/3 of the day’s full sun. Asparagus will tolerate some rougher soil where other things may not grow too well so it doesn’t really have to be rich black dirt.
I leave the fern standing until early spring, at which time I spread a couple handfuls of 10-10-10 fertilizer on the beds. If the spring is unusually dry I will put a sprinkler on the beds to help get the fertilizer into the ground and to give the plants some extra juice to get going. Other than the little time I put into the beds in the spring I do nothing be eat the goodies the plant put out. Pretty easy to have right in the yard and the spears are a very healthy food.
