need advise on asparagus care .
I have two asperagus plants growing in my yard. Ones growing and has grass all around it , the other is in with a cotonia aster bush. How should I take care of them. do I dig around the plant to get rid of the grass, should I cut the cotonia aster bush down?? This plant is skinny and about 3 feet tall ,I ate the tip off it today and it was delicious. I thought spears werre suposed to stick up from the ground,not apear on the tip of the tallest branch,( not really a branch ) .. Is there a web site showing how to look after one of these plants ?
