I have 3 beautiful plants growing now, ready to sell, 8 mths old, Bundaberg Qld lol. Try Bunnings or check with a local nursery if they get them in. Asparagus are normally planted late winter or early spring. If buying from Bunnings ask when will they have them in. Cost about $8-9 a crown. Asparagus die back in winter and start shooting in spring. Go on the internet and read up about growing them.

I'm sub tropical. My plants are 3 years old. I cut the old growth off late August, new spears shoot soon after. I pick for about 6 weeks - the ferns get away from me. This year in January I cut my ferns off and picked asparagus for about a month. The important part is to let the ferns grow and store food back into the crowns for next spring. If you over pick the spears or pick them too long it will not give the plant time to build the crown for next year.

Can I divide asparagus plants and when do I do it. I live on The Central Coast of NSW Thank you all in advance.

I have just read that you can divide into 1/4 or 1/2 but not to pick spears the first year after dividing. Do it in the early spring. Google about it and read.

Where can I buy asparagus heads. I live in Heidelberg Western Cape. Nearest possible supplier please.

The asparagus head is the shoot that comes out of the soil in spring time. You eat that part. To plant asparagus you need seeds or better you buy asparagus crowns (a bulb) usually about 6-9mtns old. Ask at your nursery or big gardening stores when will they have them in. You usually plant them in the early spring.

Are they two years old from seed or crowns?I believe the ferns die in the colder weather but not in sub-tropics /tropics. I'm sub tropic and they have not died in the last 3 years. I even stopped watering in early May this year and we have had a very dry time since then. I would cut the old ones out. Pick some of the new spears and eat. Depending on how many spears you are getting probably stop picking in about 4 weeks and let grow for next year. You have to let the crown grow in the first 2-3 years. In future from about Nov or so let the spears go to ferns-even while you are picking leave a couple go to ferns. Leave the ferns there until mid August-the ferns are growing the crown and storing nutrient in the crown for spears next year. Then cut them off and put 50-75mm of compost or aged manure on them and start watering them. And by compost I mean fully broken down organic matter or manure. Not mulch.
