Liquid Seaweed is one of the best fertilisers you can give to your plants but is possibly the type people think of when looking for such a product. Liquid seaweed is not only Organic but is completely sustainable with any damage to the environment. Most Seaweed based fertilisers are mafe from Kelp which can grow to over 50m in length.
A main benefit of using Liquid seaweed is that you can vary the concentration depending on useage, for example on your lawn you would perhaps use a weaker solution whereas for house plants or shrubs a stronger mix would be best. This will vary on soil types etc but over time you will see the benefits and use the strength that suits your plants, good for vegetables to give them a boost during the growing season.
Folia application is the best and most effecient method of using liquid seaweed and are 8-20 times more effective when applied to the leaves than directly to the soil, spray a fine mist until it drops of the leaves then spray/water the soil. The plants will start to benefit from day 2 onwards.
