Great for lawns

Thickened my buffalo grass lawn up considerably in just a few weeks. Amazing stuff. I apply to lawn (and vegetable garden) every 6 weeks. Would recommend to anyone keen to get impressive results quickly.

I am new to gardening and my prior attempts At gardening I have not had a lot of success with.

Until I discovered seasol once I started spraying the potting mix with seasol before planting and then I’d give the plant a pray with seasol and a good drink of water I have had huge success in growing my garden.

It’s great plant food, makes the soil nice and rich and helps with transplant shock too.

It is a wonderful natural product. This tonic definitely rejuvenated my lawn on a fortnightly use. Now I started using it for all types of plants in my garden. A must-have product.

How much seasole to 1 litre of water

Xy guy
Xy guy · 

Recommended is very week. Its really just a soil conditioner.
Your safe to double the dose even triple, its as weak as. But even then you'll get better results from others that are true ferts.
Power feed is good but attracts flies from its smell.
Get a soluble powder from anywhere like Mitre Ten or wherever. Manutec, Yates.. flower, vegetables, fruit ferts.
Seasol normal is as weak as and just a conditioner.
I gave up on it.
Waste of money in my opinion.

How much area will 9 litre water can of powerfeed cover

Xy guy

Hi. Use it on outdoor plants. Away from your say windows and doors. Immediate areas. Its good but attracts flies due to its ingredients. Make sure you have plates under your plants in tubs or pots if in concrete. It will stain. I found, typically that the recommended dosage was a bit under. I worked in my teen to 30s in garden centre's. So the recommendation id up by say what they say then add 25%.
Area is hard to say, as one would ask "how long do you pour say your average 9 liter water can and for how long on the same spot!?". I do this. And I don't now use Powerfeed anywhere near my house so as to not attract flies. But id do this. A 9 to 10 litre water can, 1.5 recommend dose, and cover say a 10 seconds each area of plants. Thats not a water, its a feed. Ten seconds say per plant area. Next day I give that area a water three times that just water. Wait after that till you see it dry a bit. Might take a day, 2, 3. Then water again. Feed the same way, water, evey three weeks. My misses always says, "i can't believe how good everything looks after you feed and water".
Feed, water as needed, feed again 3 weeks later. Great method I learnt working in a nursery. Hope this helps.

Seasol does nothing, it hasn't even got enough nutrients in the product to provide any benieft. I'd like to see some science to back up your marketing claims.

Try spraying the leaves instead of the putting it straight into the soil. I usually do it early morning before the sun hits the plants so they don’t burn.. it’s done wonders for my plants

Seasol Powerfeed is better mate than standard Seasol. Its a bit smelly though for indoors and can stain concrete and attract flies! To be honest though I notice it produces mostly leaf growth. I since have switched to Thrive General Purpose for mostly leafy plants and Thrive Flower and Fruit for others. My potted chilis have taken right off since doing so. Definitely growing better than they did with Seasol
