Site – Full sun is ideal. Asparagus needs at least 8 hours of sun per day. Since asparagus is a long-lived perennial, do not plant where trees or tall shrubs might eventually shade the plants or compete for nutrients and water.
How often should you fertilize asparagus?
Generally, it is not necessary to apply fertilizer for an established asparagus crop until after harvest. In fact, delaying fertilization until after harvest can reduce early weed growth. For sandy coarse-textured soils, however, 20-25 lbs N/acre in the spring may be beneficial for spear development.
How often do you water an asparagus fern?
Asparagus ferns can survive during periods of drought, but you should continue to water it every time the soil is dry. During the winter, you should water the plant less. You can water the plant once a week during the winter. The heat during the summer causes the ground to become dryer faster.
How do you make asparagus more productive?
You can top-dress with a balanced organic fertilizer, or scatter another inch of rich, weed-free compost over the decomposing mulch. Do NOT cut down the remaining ferns in summer or you will ruin your asparagus bed. Allow the ferns to grow and mature; this replenishes the nutrients for next year’s spear production.
Does asparagus multiply?
A mature stand of asparagus plants produces spears over several weeks, up to eight weeks. During this time, a healthy plant should yield around 20 spears. When asparagus plants grow in a sunny site with good drainage, proper irrigation, and adequate nutrients, the plants multiply and become crowded over time.
Should I put lime on my asparagus bed?
Lime for asparagus: Among the list of common garden vegetables, asparagus is probably the one that loves lime the most. Lime for asparagus is necessary to give the plant the ‘sweet’ alkaline soil it craves. Asparagus only needs a slightly alkaline soil, but it can tolerate soil pH up to 8.0.

What causes asparagus ferns to turn yellow?
Overwatering is by far the most common cause of yellow leaves on your fern.

You should only water after 50% of the soil volume is dry.
Are coffee grounds good for asparagus?

Should you let asparagus flower?
