I've just bought some healthy fruit bushes that were grown locally from cuttings. The lady I bought them off recommended mulching the gooseberry with seaweed. Her plants were very prolific so I'm going to do that. Shall I do that with the blackcurrant and redcurrant bushes as well?

Is it the mulching aspect or some nutrient in the seaweed? They are in pots at the moment and likely to stay there for months until we decide where the garden is going to be. If it's nutrients I could cover the pots with seaweed which would also help stop them drying out or do you think that would be too concentrated?

I have easy and plentiful supplies of seaweed, what else can I mulch with it?

It'll be mulching and nutrients, traditionally Jersey new pots were mulched with seaweed

And, am I imagining it, asparagus? It might make it possible for me to grow it as I can't imagine keeping it weed free without help!

Asparagus likes a bit of salt so a seaweed mulch is a Good Thing for it.

traditionally seaweed is collected into low heaps,rained on for a while to reduce the salt content and then used as a mulch or dug in. it has a good selection of minerals and a fairly high nitrogen content tis ace as plant food and as a soil creator/conditioner ps seaweed ferment makes good plant food(you should see my courgette plants )

Seaweed doesn't make for a great mulch it shrinks to nothing quite quickly, so no good as a weed suppressant. It's still a great soil improver, feed & mineral booster though.

As Tavascarow says. I put it out on my boxes in autumn after collecting from the seashore, then dig it in in spring and plant my early potatoes in it- well I did a few years ago, and it works!

It contains high levels of potash and should also be good for cabbages without too much raining on as they like a bit of salt. It isn't too good for runner beans without some rain though; our next door neighbour did his no good at all.
