In the spring you pick the spears after they come out of the ground - stop late Oct early Nov. To have a good crop next year you need to leave all spears/ferns to grow. These then provide food for the crown to grow for next year. Stop watering about early May and let the ferns die back. Cut the ferns off in August. As soon as I cut mine the spears start growing.

How close is too close in companion planting ? Thanks

Sorry I had that wrong. I was thinking non compatible plants. Companion planting would be fairly close taking into consideration what area both plant varieties need to produce a decent crop. Like if you were growing beans you would grow marigolds (I don't know if they are companion plants) about 500-600mm away. You don't want one crop over growing the other crop. Generally people plant things too close together - me included.

Hi, I got Asparagus crowns from Hart Nursery in Ottery. I'm going to be planting them in Kalbaskraal. Hope that they will grow there, clay soil

I have read that a new female asparagus plant is sterile & has not seed/berries. I however can not remember if it was on the net or in a magazine. So I have no proof, if I find it again I should post it.

In north central Indiana, USA, I usually trim them back after the first frost, and add mulch through the winter. Is there anything else I can do to enhance my crop next year? Bob Koch
