In my recent article about seaweed fertiliser, I talked about the wonderful benefits it can bring to your garden. Not only is it really effective in helping you to grow a lush, green lawn, it’s also very environmentally friendly, and often can be collected entirely for free from your nearest beach.

Don`t worry if you don’t live near the sea though, as there are a good range of seaweed products available which will do the same job. There are four main products in the processed seaweed range that cover most of the requirements in the domestic garden. Read on for the full low-down on what each formulation does and to find out which one is right for you.

Seaweed Meal

Seaweed meal is ideal for surface dressings on your lawn. It’s fine enough to integrate into the sward so as not to be picked up by the mower in subsequent cutting operations, and the nutrients will quickly become available to the plant. The meal is also ideal for dusting on all sorts of vegetables, fruit and flowers to both supply nutrients and deter pests and disease.

When applying to your lawn an application rate of 50 to 70 grammes per square metre is recommended.

Granulated seaweed

Seafeed Granular

Granulated seaweed is best for integrating into the soil when preparing a new lawn or when digging a vegetable patch. It’s also very good for digging in around the base of fruit trees and bushes, and for preparing annual flower beds.

An application rate of around 70 to 100 grammes per square metre is recommended.

Filtered Seaweed Liquid Extract

Liquid seaweed extract is ideal for foliar feeding of all plants. It should be mixed with water at a ratio of one part seaweed liquid to forty parts water, and can be applied through a watering can or hand held applicator. For larger areas, such as your lawn, a knapsack sprayer is ideal, and 2.5 litres of extract in100 litres of water will cover 250 square metres.

Filtered Liquid Seaweed Extract with a range of added nutrients

Liquid seaweed extract is an ideal base for mixing a range of fertilisers – such as nitrogen, phosphate, and potassium – and is suitable for all plants when tailored for a given situation. The contents of the seaweed liquid enable the plants to make the most efficient use of the fertiliser being applied. Seaweed liquid with chelated iron, for example, is a fantastic mix for use as a grass conditioner and moss killer.

Most of these mixes have a recommended application rate of 2.5 litres of extract in 40 to 80 litres of water per 250 square metres.

I hope this article explains in clear terms the benefits of seaweed in its many forms, and encourages everyone to try it out one way or another. You will not be dissapointed!
