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.

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

Evelyn I haven't tried the fat bastard variety but I have Mary Washington in at present. Grew these plants from seed and it has taken 5 years for my first really good crop although I could have picked after 3 years I didn't and the wait has been worthwhile.. The secret is to use plenty of manure- I have found sheep and cow manure is great and I dig in a few bags in early winter so it rots down well before spring. Also plenty of water in summer so the crowns don't get dry.
