When do you cut off the ferns and how low do you cut them?

Late winter and at ground level or just below. Then cover them with about 4-6 cm mulch.

I am a first time grower and am preparing the ground with compost only in a mound.what else should I add? SHEEP MANURE OR CHOOK.DO THEY LIKE LIME?

Asparagus prefers a high ph of 7.0, so my gardening books state, so yes liming likely will be needed. Can you test the ph of your soil? I give mine horse manure and sheep pellets - I have no source for hen poo, but I cannot see any reason why that would not be good for them.

It's only the end of July and my asparagus is already sprouting. Should I pick it or leave it alone? It's in it's third year and I haven't picked any for the last two spring/summers

Andrew, you could try Kings Seeds www.kingsseeds.co.nz/ (for seeds) or any good garden shop for asparagus crowns.

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.
