What month do you plant asparagus?

How much space do you need between asparagus rows?
Plant seed in spring, about one inch deep, spaced two to three inches apart, within rows that are a foot apart. Seeds can take three weeks to germinate. Keep the nursery bed free from weeds, as the asparagus seedlings will not be able to compete with strong weed growth.
What can you not plant near asparagus?
There are two main crops to avoid growing alongside asparagus: Alliums. Alliums like leeks, garlic, and onion sharing the soil with asparagus are said to stunt its growth. Potatoes. Asparagus, on the other hand, stunts the growth of potatoes when they share the same space.
Can strawberries and asparagus be planted together?
Horseradish, rhubarb, asparagus and strawberries are good companions. In asparagus rows, dig a trench 1.5 feet deep and wide, mounding soil in a 6 inch high ridge down the middle. You can plant a companion bed of strawberries, asparagus, horseradish and rhubarb that will produce for generations.
