What is Seasol?

Seasol

Seasol is a liquid organic seaweed plant tonic that benefits the health and growth of plants.

It’s made from a blend of liquid seaweed extract and other organic ingredients.

This makes it perfect for gardeners who want to avoid harsh chemicals or fertilisers that may damage certain plants.

What makes Seasol special is its unique profile of bio-stimulant trace elements, acids, and nutrients which stimulate root development and help build plant strength against disease and stress.

What type of plants will benefit from Seasol?

Seasol is great for all plants, including lawns, fruit trees and vegetables.

In fact, it can also be used on any shrubs, flowers or ornamentals in your garden.

It’s also perfect for indoor plants as well as your native and exotic varieties.

Seasol works great on:

  • Trees
  • Veggies (including herbs)
  • Fruits
  • Flowers
  • Shrubs
  • Houseplants (indoors)

When to apply Seasol

Unlike fertiliser, Seasol can be applied at any time of the year and at any time of day.

It can also be applied in any weather conditions, including on very hot or cold days or when it is wet.

How often should you apply Seasol?

For established plants, ferns and lawns apply every 2 – 4 weeks throughout the year.

For newly laid lawns, apply once per week (maximum) for 3 – 4 weeks or until well established.

While you can use Seasol at any time of the day, we suggest applying in early morning before the sun is at its hottest or after sunset when evaporation rates are lower.

It’s best to stick to the above guidelines for application frequency, but keep in mind that Seasol is not a fertiliser so it won’t burn your plants, even applied regularly.

How much Seasol should you use?

The application rate varies by plant.

Here are the recommended rates:

  • Ferns and indoor plants: 20ml per 9 litres.
  • Vegies, herbs, annuals, and established gardens: 30ml per 9 litres.
  • New lawns: 50ml per 9 litres (with a higher frequency than established lawns).
  • Established lawns: 100ml per 9 litres.

How to use Seasol

There are many ways that you can apply Seasol to your yard.

If you are using the regular concentrate, make a mix using the above measurements, and then use a sprayer to apply to your garden.

You can also use the Seasol hose-on product which attaches directly to your hose, so you can then water your lawn or plants with a mixture of water and Seasol. Each container should last around 10 minutes.

The video below provides a full guide on the Seasol Hose-on product.

Applying Seasol to specific plants

Roses

To encourage root development, apply Seasol to roses at planting time and then periodically through the year. Use 30mL of Seasol per 9 litres of water.

Citrus

If you’re planting citrus, water in first with Seasol to stimulate root growth then regularly through the year. Citrus will also benefit from a complete fertiliser in Spring.

Keep in mind that because citrus trees are shallow-rooted, they need to be planted where their roots will not compete with nearby grass or weeds for water and nutrients.

Potted Plants

The easiest way to apply Seasol to potted plants is by using the “Seasol Pots & Plants” product which includes a convenient spray applicator.
