Seasol Complete Garden Health Treatment 4L – Seaweed Plant Tonic Concentrate

The Seaweed Tonic That Keeps Your Whole Garden Healthy

Seasol is Australia's well-known seaweed-based plant tonic, used to improve plant health and help gardens cope with the ups and downs of the season. It is made from a blend of Ascophyllum nodosum and Durvillaea potatorum seaweeds, both rich in natural compounds that support plants. As a concentrate, this 4L bottle goes a very long way once diluted, and it is safe to use on all plants, including vegetables, fruit, flowers and lawns.

More Than a Fertiliser

Seasol is best thought of as a health tonic rather than a straight fertiliser. It enhances root growth and is ideal at planting time, helps plants deal with stresses like pests, heat and frost, and stimulates flowering and fruiting. It also encourages beneficial soil micro-organisms, which supports healthier soil and stronger plants over time. Used regularly, it helps your garden establish, recover and perform.

Ideal at Planting and Through Stress

Because it supports root development and reduces transplant shock, it is especially useful when planting or potting up, and any time plants are under pressure from heat, cold or pests. That makes it a go-to product to have on hand year-round, not just at feeding time.

Easy to Apply

Simply dilute Seasol with water as directed on the label, then apply it as a foliar spray over the leaves or as a soil drench around the roots. Both methods are quick and easy, and the concentrated formula means a single bottle covers a lot of garden.
