Work out your climate zone from the blue tab above. Then check asparagus and look in the calendar to see what month you can plant or google it..

Hi, I live in Vancouver, BC, Canada. I want to start growing Asparagus in my very small backyard to start with. I am looking for someone who can guide me. I am ready to pay consulting fees. Please advise. Best Regards, Ash

You can absolutely grow asparagus in Vancouver. Start with a year old crown, make sure there is no grass or other weeds in the space to compete with it and plant it deep - usually the crown will come with directions, but approximately 8 inches deep. you will be able to harvest a bit in a couple years and loads within 5-10. This is what worked for me in Saskatchewan so you shouldn't have any issues.

Work out your climate zone from the blue tab above and then check to see if you can plant asparagus in the calendar table at the top.

Asparagus can be notoriously difficult to harvest so I recommend going on the internet and asking your question, including your zone information.....you'll find countless sites that discuss growing this challenging vegetable.

Asparagus is simple to harvest. The shoot/spear comes out of the ground and when it is 6-12 inches high, cut it.

I live in Gembrook Victoria. I have asparagus ferns about 3 inches tall, can I plant them now? Can I plant them near garlic? Thanks in advance.

Asparagus needs a bed of their own as the crown will grow 18-24

I have just noticed that I have spears on my asparagus. They have been in the ground for 2 years. My query is to do with the ferns that are still there from last year. The ferns did not die down and I read somewhere to leave the ferns and that they would die of their own accord.But they did not so I guess this was incorrect. So... do I now cut off all the ferns as the spears are now appearing or do I reduce the number of ferns? In future do I cut off all the ferns when the spears stop appearing or at a specific time frame? ( say Jan Feb? ). Thanks in advance for your assistance.

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.
