I’m on the Sunshine Coast Qld. It’s autumn now so do I cut back my asparagus plant now. It’s starting to die off but still sending spears up. Thanks

Leave until late August to cut back, then fertilise, compost and water. Stop watering in the next month.

I stop watering at the end of April and just leave it. I cut back the end of August and apply fertiliser then water and 4-6 (??)

Hello my plant is about 4yrs old was getting skinny shoots until I put dried chicken manure from my chooks on and within weeks I started getting thicker shoots the size of an index finger, I'm in Alice Springs where we get minus 5 temps in winter when is the best time to prune as I've never pruned it before. Thank you looking forward to hearing from you.

Asparagus is a 'gross feeder' meaning that it likes rich soil with plenty of nitrogen. That is why the poultry manure gave them a burst. Harvest the spears from Spring into Summer, then let the spears grow into 'ferny' heads. Keep the water and nutrients up, use a good mulch to retain water, then cut the heads off at ground level when they turn yellow in late autum. Leaving the ferny heads on helps the plant to regenerate. You should have a good crop next season. Asparagus is quite cold hardy. Trust this helps

I planted Asparagus last year. It has done very well and I fertilized,mulched when need to , or cut ferns when need. My question is, at the end of December, a few Asparagus began popping up, and tips purple. Is it ok for them to pop up that early?

You generally cut ferns off end of Winter and pick new spears for 2-3 months in the Spring, then let the ferns grow again to feed the crown for the following year. If the weather is warm enough they will keep sending up new spears until end of Autumn. I just cut mine off for a quick feed over the last month of summer. Mine are 5-6 years old. I'm in Australia - sub tropical.

I have a patch of purple passion which are tons sweeter than asparagus and they are great producers! We also have a patch of tried and true Millennium. We planted 10 crowns of each about four years ago, and they are enough for our family of 4 with some to spare. I'd love to freeze some and I'm thinking about starting a second patch of about 20 crowns to have some for preserving. Also, remember that when you plant your crowns, you don't harvest from them for two years. Just let them go to fern. They are quite lovely in a herbaceous border with other perennials. These are a gift to your future self! :)

Google what varieties you have in the USA and try one or ask at a nursery.
