Growing Asparagus

My first attempts at growing asparagus were from seedlings. Very slow growth and few spears. Then I put in Mary Washington crowns 2yrs old. The first year I harvested a handful of spears. This is the second year- I’ve had continuous harvest since a early spring. As suggested, I’ve let a few ferns grow so that the crowns can develop and will increase my feeding so I get more spears next year. I have boy and girl crowns. Do you recommend an all purpose fertiliser at this time ?

Asparagus takes about 4 years to be in good production. I assume when buying crowns they are 12 mths old (probably less). This is what I do sub tropical - mid August I cut the old ferns off, give the patch a good watering, then apply a generous amount of NPK of about 12-4-14, give a watering and then put 6 (??)
