I have been growing for 3 years and done a bit of research. I don't have frosts. August is the end of winter here. Temps start rising from 6-10 to 12-15 by end Sept at night. Days go from 20-25 to 24-28. I cut mine 1st week of Aug and apply compost and horse manure. The manure is new but I'm going to try and decompose it before hand next year. I also apply some fertiliser once it starts to shoot spears. 3-4 teaspoons to 9l of water.

When do you cut the plants back ? They do not die in my garden. I need to know when to cut them down. Thanks. Sarah

Here in South Carolina, my asparagus grow April-Oct. So you may need to let them store food for 6-7 months. Clemson Extension says let the ferns grow with out cutting/harvesting spears, in July cut the ferns back & harvest new spears. So I guess you could cut them back a week or two before you want to harvest the new spears. I, however have not tried this .

I buy my asparagus crowns from Green Harvest who are located in Queensland and sell their products, seeds and edible plants by mail order or if you live near them you can buy in person. They are an organic plant seller.

Hi, I planted an asparagus plant last year (2017) in July. Cut back the ferns in August this year (2018) and topped with compost. There are a few spears that have come through now. What should I do with them? Should I cut them back or just leave them? Thanks

I’m in Melbourne outer east, I have 6 asparagus plants from one and two years old. Only one of the newer plants has spears coming up from about 2 weeks ago. At this stage I’m leaving them to get stronger.
