Leave them to grow. You can stake them if you prefer. Once they die off, trim off the dead bits. Definitely mark where they are, as they will probably disappear. Do not harvest for at least 2 years.

One 6b - Bought crowns in late spring and they were misplaced.until now August. They are not dried out and I'd like to salvage whatever is possible. If I plant them now ANDif they grow, the season will be over and cold by October. Should I refrigerate the crowns and maybe wait til spring to plant or go ahead and put them out now? Also, would it be of benefit to use innoculant to stimulate them, individually pot them indoors under grow lights and gently transplant to an outside bed in spring? What makes sense?

Thank you. I will wait until spring next year, even if fronds are browning. I have picked and eaten the emerging early spears. And I have covered the plot with heavy shade mesh on a frame, to avert any frost damage. This is the first time in 5 years that the spears have come up in July!

Have just cut down old fronds. Noticed a few new asparagus spears coming up. It is still winter, and as we get frosts here in Ballarat, should I cover the crowns with some mesh do that they don’t get burned, or just accept the loss until spring flush?

Pays to read the notes here. It does say they like cold and frosty weather. Don't cut fronds until end of August.

Thank you. I cut down the ferns because they were browning. Thought it was correct. That asparagus like cold and frosty weather, do the early emerging spears not get burnt by frost at -3C?

i live sub tropical. A natural tendency to cut some thing is for it to grow, so don't cut until Spring. I have some spears shooting throughout the year, even now. You cut the new spears off when they are 200-250mm long and eat them. What -3C does I don't know but you should know by now.

No planting time for asparagus in your climate zone. Maybe wrong climate.

I planted asparagus three mths ago. My zone is between 9 & 10. The weather has been pretty windy and cold. I water well so cold won't dry the plant. But when will i see asparagus start growing?
