Have been through a couple of bottles and used on both outdoors and potted plants. Cannot honestly say I saw a difference in the plants, maybe it benefited the soil in some way but did not notice any changes. While it is economical as it's concentrated, it is just seaweed, and I think you need more than a one-ingredient product for all-around garden benefits.

I have used this all natural fertilizer/ soil conditioner a few times before and absolutely love it used of course in conjunction with power feed! Beautiful lush healthy plants!
Glad I could purchase this exact item from Mitre 10 at a reasonable price. The product makes such a difference to the strength of plants, seedlings, vegetables enables them to withstand the vagaries of Tasmanian weather
Such a great tonic. I use it when I transplant to reduce shock and help new roots to form. Helps plants cope with really hot weather. Feeds the good bacteria in the soil, living soil-> great healthy garden.
Purchased this product thinking it would help some plants that were struggling. It did no good. Then tried THRIVE. That worked wonders. The plants in question are now very very healthy.
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.
I have used Seasol seaweed tonic for many years. It is an all round favourite in my garden, planting, potting or feeding plants. It’s very easy to use any time of year.
Improvement and growth seen in my plants within 2weeks! And because it is concentrated, it lasts a long time too. Good value for money.
