The most important part of raising asparagus is the preparation of the soil before planting. It is almost impossible to have too much fertilizer and organic material. Add things that take years to break down such as redwood compost and peet moss. Also try very slow release fertilizers mixed with faster ones.

I have a 30 foot by 30 foot area dug and ready for preparation this fall. Note: asparagus is a long-term proposition and a major investment. A good bed should last 10-20 years, often a lifetime.

You can't grow too much good asparagus. Giving the excess away ain't exactly like trying to get red of 2 foot zucchini.
