Hi Kim, you need to cut to old ferny growth every year once it starts to die off.

I cut the ferny tops off my 2 year old crowns a few weeks ago and covered with lucerne hay. The weather has been so warm that they are sending up spears again. Should I cut these off or let them grow up to further feed the crowns. Am hoping for first good crop this spring.

The weather sure is warm Helen. I'd be inclined to cut your spars off and have some late season asparagus. With winter just around the corner the spears are unlikely to develops any further.

I have had my asparagus crowns in for more than 2 years but they are only forming thin shoots. How can I encourage thicker shoots to grow?

Thin stems usually means the plants need feeding. Cover them with manure and compost over winter and come spring fertilise with some pelletised chicken manure. A good mulch of straw will help also.

In Newcastle NSW my 5ft asparagus ferns shade part of my Veg garden. Can I trim the tops a little? They never really brown off much - when is the earliest I can cut them down for winter??

I will be planting asparagus crowns this year, but need real advice as to how many, when in full production, for 2 asparagus lovers. So far I have been told anything on the spectrum from 3 to 25! Any real knowledge would be greatly appreciated.
