Low germination/growth rate

We had our crowns delivered in April. We planted them as directed within less than a week. Only 14/25 crowns have grown and it has now been almost three months. We got the Atlas variety at the same time and all of those crowns sprouted and are doing well. Will be using the seeds from the few female plants in our Atlas crowns to fill in the gaps in our JerseyKnight beds. The plants that sprouted look like they are doing well, just really low sprouting rate.

Jersey Knight Asparagus

All of the Jersey Knight Asparagus is up and growing well.

So far so good

I planted the crowns the same day they arrived. Some were slow to come up but eventually all sent up shoots. Now all are growing well. I look forward to seeing how they do over the next couple of years. So far so good.
