Leave the plants to grow & mature for another 2-3 years. You can trim back the ferns (to 5cm) either in the fall after they turn brown or at the beginning of spring.

Crowns/plants don't usually become available until mid/late winter.

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 would like to know how to grow asparagus, where to get the seedlings, when can I grow and at what temperature, lastly how long does it take to harvest and how? I live in Lesotho but the site could not list my country hence why South Africa since Lesotho is inside South Africa geographically like a kidney in a body. Thank you

If possible purchase 2 yr. old "Crowns". These are asparagus plants (roots). There are a number ideas for how to plant them - just visit Youtube or Google for step-by-step pictures along with description of soil mixture and fertilization. Then wait another year before harvesting. Honestly I have never grown from seed. But in either case you are looking at a couple of years before you will have a decent crop.
