Try Bunnings or a nursery.

I am new to planting Asparagus seeds harvested from my garden. I live in the USA in Northeast (Rhode Island) I had a bumper crop of Aspargus this year and have harvested all the red Seeds: When and how should I plant these seeds?

We have just moved to a little old (ish) cottage in Maldon Victoria and to my delight have just discovered asparagus growing in the back yard. It is not in a "garden bed" as such, but obiously once was. Grass has grown as lawn all around it and spears are popping up left right and centre. How do I encourage and look after it at this late stage (mid October)?

Lucky you!!! To an area about 1 & 1/2-2' around all the plants and between the plants give it a good watering. Next day pull all the weeds out. If you can, buy some horse or cow manure or compost and place about 3" thick over the top of it all. If the weeds are a real problem over the summer I would suggest during next winter when the asparagus ferns all die down, transplant the crowns into a nice prepared garden bed - then about August Sept each year put a 4-6" layer of aged manure or compost on them.

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.

Asparagus is perennial and will bear for around 20 years.
