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.

Are the seeds poisonous to chickens

Hi, I planted a crown about two years ago and have recently enjoyed several fresh sprouts. I'm often away and have come home to ferns a number of times. A friend told me to increase my yield. Simply dig out the crown, cut it in half then replant the two halves. Is this the case? Thanks, Johny

By dividing crown you can get more plants, but they all go back to producing small shoots for up to two years and a crown that was planted two years ago would only just be of asparagus harvestable size and have nothing to give yet in terms of splitting. Chances also are that you can kill the crown or split when not done at the right time. Best to just buy another crown or sow some seeds and let them all mature.

I live in southern Tasmania and recently bought a couple of crowns, they have the delicate fern growth and I was wondering if I can separate (cut into sections) the crown before planting in the garden to have more plants.

I planted my asparagus seeds in oct/nov last year in a tuna tin with a clingwrap cover, creating a greenhouse almost. I have now planted them outdoors in planters, and they have shot up. I do think growing from seeds take a while, however, I'm quite content to wait. It seems like its quite a rewarding plant to wait for :)

I bought my plant from Jungle Garden Nursery, Durban.
