Asparagus is one of the few true perennial vegetables that we grow in Minnesota.
As a perennial it is often overlooked, yet can be a very healthy, delicious, and productive stand. As the stalks emerge, if you have not fertilized the previous fall now is the time. Using fertilizer right for your soil is the best idea, but remembering that the plants need less nitrogen and more phosphorus and potassium depending on the soil levels. It is also important to include some sulfur.
Asparagus also needs a watchful eye tending it as if left too long it bolts fast causing it to get woody. If well fertilized and with proper moisture and heat the stalks often grow 2"/ day.
My favorite recipe is to grill it with olive oil and butter until it is tender but not too well done. It would be seasoned with a simple blend of garlic salt and pepper!
Please see the University site that has lots of good info for growing .
