Have decided to plant some asparagus crowns this year but am coming across conflicting advise re:trench.
One website (which looks really good) has some detailed diagrams and explanations saying to dig a 10 inch trench and lay 3 inches of well rotted compost at the bottom before filling back in and planting the crowns.
however the packet says do not add compost until the crowns start to appear through the soil
anyone any tips? thank you in advance
