MAKE SEAWEED FERTILISER
Give your plants a boost with some homemade seaweed fertiliser. Take a trug to the beach and collect seaweed from the high-tide line, then take it home and rinse off the sand and excess salt. If what you’ve gathered is tough and dry from days spent baking in the sun, take out your spade and chop it into smaller pieces to help speed up decomposition. You can also run your lawnmower over those bits to reduce the size even further. Avoid damage to your mower blades by removing the holdfast (the anchoring root structure that glues the kelp to the sea floor), as it’s hard and often contains stones. Place seaweed in a barrel or large lidded bucket and cover with water. Leave for a few weeks to break down, then strain, dilute with fresh water and spray on plants.
