Hi, My partner and I have purchased a property in the Adelaide Hills and are keen to find out more about growing asparagus - not sure where to buy seeds etc can somebody point us in the right direction ? Thanks Jacquie

Try Bunnings or some nurseries or look on the internet. Buy some crowns (9-12 mths old). Can start from seeds - will take a year longer though and it requires a lot of attention. I had up to 30 seedlings last year and only 6 survived.

Planting asparagus from seed will take a lot longer before you get a crop, three years. Go to your local nursery and ask for asparagus crowns, which can then be planted out. This can still take up to 2 years to be productive.

hi there what is the best possible way to grow asparagus in KZN. Tunnel, with raised beds? What Fert do I need, how many times do I water them? Want to start a small bunch to see if it will work :)

I have transplanted asparagus crowns that were well established approx 3 weeks ago. They are now sending up spears and we had our first feed from the new crop last night. Should I be letting the spears grow out instead?

Should be able to eat them.

On asparagus - I've just purchased one year old crowns (7 in total). What kind of crop could I expect next year? How many spears does each crown produce?

I have read so many different things about what to expect. I planted 12 mth old crowns and last year I picked for about 4-5 weeks from 3 plants - I feel I could have picked them for 3 mths. I had massive ferns early this year. I picked about 70-80 spears last year in the 4-5 weeks. You probably have colder weather.

Hi mike as I explained on my last post about transplanting crowns into a new bed, at this stage the once I transplanted are still dormant which I expected it will take I think for next year to get a some spears.The other crowns that we have in the same bed are sprouting through and looking good .By the way I thought asparagus shoot through in spring .Anyway I put lots of horse manure on all of them however I think cow is better .What do you Think?

Have them come up yet? I remember mine were slow the second season. They're on year six or so now and I've been harvesting for a month now.
