Hi Andrew. I bought my first packet of 5 one year old Asparagus crowns from Mitre 10 in Hastings in 2 Sep 2016. I bought another packet of 5 crowns from The Warehouse in Hastings on 25 August 2017. I planted and fed them in accordance with the instructions on the packets and have had my first feed of Asparagus on 21 Sep 2018 (from the 2016 plants). My husband and 2 children then had their first feed on 15 Oct 2018. We harvested our asparagus until 21 Nov 2018 and then let them go to fern. We did not touch the 2017 plants at all but will be able to eat them in spring 2019 until early November and also be able to eat as much as we can from our 2016 plants with continued harvest through to the middle or end of December at least.

how often do you feed asparagus and how do they like the soil.

Dis, your asparagus spears will be ready to cut when they are about 20-25cm (8-10in) high. Cut with a sharp knife, don't pull, close to the ground. Only take a few this year and leave most of them to turn into leafy fronds (fern) as that will increase your plants for next year. Once planted, a well cared for asparagus bed should keep going for many years. Remember to feed well.

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.
