Asparagus Bed Size
Depending on the size of your garden and any other plants you intend to grow asparagus may not be a good choice for you to plant.
Asparagus bed size. Crowns should be planted between 8 and 12 inches apart on center. When harvesting for the season is finished the shoots are allowed to grow to provide food for the underground root system the crown. In sandy soil that trench needs to be 8-10 inches deep.
Heres a tip I learned this spring. Asparagus beds are productive for decades if well prepared sited and maintained. As asparagus grows taller backfill the rows with soil until it is eventually level with the garden bed.
As your asparagus grows the asparagus crowns will start to sprout spears with most growing between 2 and 3 inches tall. A single row of asparagus plants set 15 inches apart will fill in to form a 24- inch-wide bed or you can grow a double row in a 36-inch-wide bed. Keep the asparagus bed weed- free as asparagus plants.
Plants may need supporting as they grow quite tall and should be cut down at the end of the season. Light Full sun Stalk size at harvest 7 to 9 inches tall Matures perennial first harvest a year after planting Plant spacing 12 to 18 inches Plant size 4 to 5 feet. Rows in Michigan are planted from 4 to 5 feet apart to give fern room to grow in the summer.
You can still grow asparagus on heavy soil but its worth creating a raised bed. Set up a 8x3 framed bed per person 8 crowns per bed. Asparagus crowns should be planted outdoors after mild spring weather has arrived.
To grow well asparagus plants should be fed well and kept weed free. Weeding and removing female plants. Rather diameter is determined by two factors.
