Hi,
I keep hearing about seaweed as a plant feed... I've come across liquid seaweed concentrate suggested to be diluted as a foliar spray.
1- would my hostas, ferns and other leafy plants benefit from this?
2- What other plants would benefit? I have an allotment so am thinking vegetable plants as well as garden plants.
3- Does it have a shelf life? As it is over £10 and recommended to be diluted 1 part to ten, i need to know I will get good use of it this season if it needs to be used within a given time.

It's not really a fertilizer as such, but it does provide all the trace minerals that most plants benefit from. No point in using it as a foliar feed on anything with glossy leaves though as it just runs off.
Most plants will benefit from it.
Being organic it will have a shelf-life. I've just had a look at the 10L bottle I have of Maxicrop seaweed extract - there are no dates on it.
I use it about every 3 weeks during the growing season, but not at the same time as any other liquid feed if applying as a root drench - leave it a couple of days.
Wisdom is not putting it in a fruit salad.
I agree all your leafy plants will benefit. The seaweed left from making the plant brew goes into sweetcorn and mini pop trenches also potato trenches before planting.
I've used it straight from the beach as a mulch in pots, it deters slugs because of the salt and it can be used as a mulch around most plants and used weekly doesn't seem to upset te plants.
