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.

If you have a Bunnings store contact them about when they might have them and cost. Usually August and about $10+ per crown. Or try internet seed selling companies.

What is the best seed variety for tropical climate that’s hardy and disease tolerant?

You are better growing from crowns. Read other posting about buying crowns from Bunnings. If you want seeds go on the internet to Boondie Seeds and look at their varieties.
