When & Where to use liquid seaweed

While we promote this as being perfect as a lawn feed, you can actually use liquid seaweed on flowerbeds too.

It’s specially designed to enhance the health of your grass (or plants) at home during the Summer months.

This is a liquid solution that needs to be mixed with water so you can apply it during hot weather when the lawn is actively growing. Don’t apply if frost is forecast.

You can also use this as your first application on newly established seed, especially if you seeded in Spring as it will help with the growth of the grass.

If you’ve got dry patches on your lawn, use Liquid Seaweed during August to repair them with no guesswork required. Our customers have seen up to 36% more grass coverage when they apply it!

When to expect seeing results from liquid seaweed

Liquid Seaweed is a fast acting solution that will start showing results within 7-10 days. Any light green patches will start to turn a darker lush green.

It’s particularly useful when drought is expected as it will act as a wetting agent to help prevent the lawn going brown.

Techie Specs

Liquid seaweed increases nitrogen-fixing by releasing nutrients into the soil that stimulate breakdown of ammonia and nitrate into ammonium and nitrite, making them available for uptake by the lawn.

Liquid seaweed also contains extracts from wetland plants which give it an alkaline pH balance to regulate acidity in the soil.
