A great product for anyone who loves their plants. I’m never without Seasol. It’s easy to use and the garden always looks healthy. All plants appreciate some Seasol.
I have been using Seasol for a long time and was disappointed when it became unavailable except in spray form. Now all is well and so easy to use from a watering can.The other products I bought are also well matched. Regards
One of the “must haves” in the garden shed. Ideal for watering in new plantings and providing regular added nourishment to established plants.
It’s good. Easy to use - just add a small amount to a watering can. I water all my indoor plants with it 3 monthly. Great results.
I use Seasol regularly on my plants. It’s great to establish new plants and seedlings.It assists with flowering of annuals and produce with vegetables. A fantastic product.
Only treats 480m2, compared to 600 grams of ecoseaweed soluble fertiliser that treats 6600m2 for only 31 dollars. You do the math
Gives your plants a quick added boost. Great to combine with Power Feed. Mix in a 2ltr hose spray container and your plants will quickly grow new shoots. The seaweed smell only lasts 24 hrs and is well worth putting up with.
