Amgrow Wettasoil with Seaweed Concentrate 1L – Soil Wetter for Lawns & Gardens

Help Dry Soil Absorb Water with Amgrow Wettasoil

Amgrow Wettasoil with Seaweed Concentrate is a liquid soil wetter that helps water soak into dry, sandy and water-repellent soil instead of beading on top or running off. Enriched with seaweed extract, it not only improves how water moves through the soil but also helps reduce plant stress and support healthy soil and plants. It is a handy, economical treatment for lawns, garden beds and any spot where water is not soaking in the way it should. This concentrated 1 litre bottle makes up to 600 litres of solution.

How the Soil Wetter Works

When soil dries out, especially sandy or hydrophobic soil, it can become water repellent, so water sits on the surface, beads up, or runs away before it ever reaches the roots. Wettasoil is a non-ionic surfactant that breaks down this water repellency, letting moisture spread evenly through the soil profile and down into the root zone. The result is more efficient watering, less runoff and waste, and water that actually gets to where your plants can use it.

Enriched with Seaweed Extract

On top of its wetting action, this formula is enriched with seaweed extract, a well-known garden tonic. Seaweed helps reduce plant stress and supports overall plant and soil health, which is especially useful going into hot, dry conditions when plants are working hardest to take up moisture. It is a nice bonus that works alongside the improved water penetration.

Where to Use It

Wettasoil is versatile across the whole garden. Use it on established lawns, garden beds, flower and vegetable gardens, and around trees and shrubs. It is particularly worthwhile on sandy soils, dry garden soil, water-repellent soil and localised dry patches, the kinds of areas that stay dry no matter how much you water. Apply it directly to the soil rather than relying on the foliage.

One Litre Makes 600 Litres

This is a genuinely economical concentrate. At the label rate of 15mL per 9 litres of water, the 1 litre bottle makes around 600 litres of prepared solution and treats approximately 266m² of soil. One application can keep helping water penetration for up to 12 months, though this can vary with soil conditions, rainfall and how you water.

Safe and Eco-Friendly Around the Garden

Amgrow describes Wettasoil with Seaweed Concentrate as a low-aquatic-toxicity formulation that is safe and eco-friendly around pets, waterways, soil and the environment when used as directed. As with any concentrate, do not pour the undiluted product straight into water, drains or ponds, clean up any spills, and use only the recommended amount.

Shake the bottle, then mix 15mL of Wettasoil into 9 litres of water and stir or agitate thoroughly. Apply the solution evenly over approximately 4m² of soil, watering the whole affected area and treating dry patches evenly. Apply it directly to the soil rather than the foliage, then follow with normal watering. Do not apply the concentrate undiluted, and do not exceed the recommended rate. Amgrow suggests treating garden and lawn areas roughly twice a year to keep water penetrating well.
