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.
