On my farm I have started using Sargassum seaweed as fertilizer. I will be making another video talking about how to use it. For now below I will tell you how I to use it.

How to Make Seaweed Fertilizer

There is disagreement amongst gardeners about soaking or rinsing fresh seaweed to remove sea salt. Some experts suggest soaking the seaweed for about an hour and/or rinsing it. Other experts argue that the salt is minimal and rinsing removes valuable nutrients. Nonetheless, fresh seaweed is generally dried before being tilled into garden, mixed into compost bins, laid as mulch, or made into DIY seaweed fertilizer tea or powder. Once dried, seaweed can be used immediately in the garden or chopped up, mulched, or ground. DIY seaweed fertilizers can be made by simply grinding or pulverizing dried seaweed and sprinkling it around plants. DIY seaweed fertilizer teas are made by soaking dried seaweed in a pail or barrel of water with a partially closed lid. Infuse the seaweed for several weeks then strain. Seaweed fertilizer tea can be watered in at the root zone or used as a foliar spray. The strained remains of the seaweed can be mixed into compost bins or gardens.

The first batch I left out in the sun for about 2 months. I think that was way too long. I have no access to running water. So I let the rain rinse it. I have found that a few days of rinsing it is best. the next few batches I made, I left it for 2 weeks. Depending on how much rain I get and then I placed it on my eggplants. They are loving the seaweed. So just experiment and see what works for you. I hope to continue to get more and share more videos on how I use it and will give any tips and advice.
