Is it helpful to put sea weed on asparagus plants as manure?

Any organic matter needs to decompose to be able to be used by plants. Sea weed is great but it needs to break down first. Compost it now so to have it ready by end of August.

what Fert. do you use on your asparagus

Try using composed manure or compost. Any general fert would do. The ferns that have grown the last 6-8 months have put a lot of energy into the crown to supply nutrients for the coming crop.

We planted our asparagus in summer and although it is winter now, the ferns are still green. There wasn't any berries in autumn, Do we have to cut off the ferns or just leave them to die out?

Don't water them from now until late August and then cut them.

Thanks Mike. My crowns are at least 5 years old but the spears are not all that thick. I'm just out of Mackay so I dont think I have been giving them enough attention.

Good draining soil. Cut old ferns off, early to mid August. Apply some compost 4-6

I have asparagus plants in garden with shade cloth will this be enough sun They grew well last summer but only the first year

HI Kaye, I would think they need at least, good morning sun. I have mine in a bed that faces North so they get a decent amount of sun. But are shaded from summer late afternoon sun as here we get over 40 degrees in summer. What density is the shade cloth, 50/70/90?
