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.

Hi Mike... I'm in zone 9b, as well. I'm wondering if you decided to plant asparagus.... and if you did, how did it work out for you? I just bought crowns and hope to plant this week. I have a spot that is cooler than most of my property. Wish me luck!

I put crowns in last summer and cut the canes down in the late fall. I now have first asparagus in March. Should I let them grow and not pick them?. No frost here. 1200 feet up and maybe 4 miles from the ocean in California. Fog at night in May-July but sun during the day. Warm to hot fall.

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.
