Seaweed has been used by farmers for centuries to improve the soil for farming.
You can purchase it in liquid or granule form to add to your garden. Every brand has a different NPK ratio, depending on whether they have fortified it with add nutrients. This is fine, but you want to familiarise yourself with this so you know what you are adding to your garden.
It is recommended that you add it to your garden every 2 - 4 weeks. As a reminder, I regularly do Seaweed Saturday posts. Each post I focus on a different benefit of seaweed.
- they help thicken the plant cell walls which benefits plants by making them more frost tolerant, and heat resistant in summer.
