What varieties of asparagus will do well in zone 8a? I live West of Fort Worth, Texas I wish to buy 2 year old or older “Crowns”.

i have cut back my asparagus when it died back, about 3 weeks ago. I covered it with manure and compost and it has begun to grow again. The new stalks are about 15 - 20 cms already but only pencil thin. I really want to harvest white asparagus, should i mound the soil up over the asparagus now? or should i let it just grow?

Plant white asparagus if you want white. If plant is old you could cut the spears - thin ones. If plant is 1-2 years old could let the thin spears grow. Read up about male and female asparagus.

Try Bunnings or a nursery.

I am about to plant a raised garden bed with Asparagus, I have done the research but am confused with the depth that the crowns should be planted. Would any of those that have had success give me a little advice. Thanks in advance - Lee

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.
