Asparagus -- add clay soil or sand?
Hi, planted 200 crowns of Jersey Supreme.
Had hoped to get Jersey Knight since I have clay silt loam (not heavy clay, but a really thick loam). Trenches are 'loosely' covered with 3-4 inches of heavy loam (as loose as heavy clay silt loam can be!), and will be 6-7 inches deep when filled in.
Any problems with Jersey Supreme in non-sandy soil? Does Jersey Knight really do better in soils with clay? Anyone add sand into the asparagus when filling?
Extensions say not to get too wet, so I had not watered until now. Subsurface stayed moist but the surface got really hard so I started to water lightly. The asparagus has not come up after 9 days. Some are close, and some have only started budding. How long do they take to come up (cool/light frosts)? How much have others watered to help emergence?
The area is on a slope, and I would rather not have drainage soak into just the sand and rot the crowns unless sand has helped others.
