Always love using this product and return to it every year. I haven't found it too harsh on my plants, like some fertilisers can be if you don't dilute / use correctly. Given this is naturally sourced and helping the environment, I also like to use it - seems like a win-win. I don't mind the smell but others in the house can be put off by it. So, I like to water my indoor plants outside and leave them out there over night to help the smell go away. Sometimes a gentle water of the leaves before bringing them in, can also help with the smell and remembering to wipe down the pots.

Great product. Have been using Seasol for many years on all my plants, including veggies. Visible results in days.

The best soil conditioner. I've used it for years. It doesn't replace organic fertilisers but helps balance the soil as a supplement. Great on seedlings and any transplanted newies!

Excellent quality and great value. Great to any plants or vegetables. A-1++++++
Seasol would be one of the better liquid fertilisers that I've used. Does the job well.
I used under the amount it recommended and put in a 9 litre watering can for 20 plants and after a few days all my plants have yellowed and died, and I’m almost sure it was from the fertiliser they were completely fine before it. And I realised that it has a really high amount of nitrogen which destroyed my plants, won’t purchase ever again.
Great product and well priced. We use Seasol on our veggie patch and have found an increase in produce over the years since we started using it. It is part of our soil care along with compost, coffee grounds, worm water etc. each product has its use.
Long lasting, being a concentrated mixture. Plants appear to respond very quickly to a dose of the diluted fertiliser, producing lush growth.
It's very good, has saved some plants that were looking more than a bit tired. Very happy with the purchase.
Plant food is great, the bottle top is rubbish - doesn’t twist off properly and causes a mess. But the actual seasol works wonderfully on my plants
