Seasol Seaweed Concentrate is an Australian made seaweed tonic, supplied here in a 10 litre container for gardeners working at scale. Diluted and applied to the soil or over the foliage, it supports root development, helps plants hold up under stress and feeds the microbial life in the soil. The 10L size is for large gardens, landscape jobs and anyone who goes through a small bottle in a fortnight.

What it does

  • Drives root growth. It encourages strong root development, which is what gets a new plant established rather than merely alive.
  • Improves stress resistance. It helps plants cope with heat, drought, frost, pests and disease, so it earns its place before a heatwave or a cold snap rather than after one.
  • Safe across the garden. Suitable for vegetables, herbs, flowers, trees, shrubs, lawns and Australian natives, which means one drum covers the whole property.
  • Builds soil biology. It increases beneficial microbial activity in the soil and supports better flowering and fruiting.

How to use it

This is a concentrate, so it is diluted before use. The dilution rates differ between general watering, foliar spraying and planting, and they are printed on the label. Follow the label directions rather than a rule of thumb, and mix only what you will use.

Apply it at planting or repotting to reduce transplant shock, and water it over direct sown seed to improve germination rates. After that, apply regularly through the year. It is fast acting and works best as a routine, not a rescue, so a steady schedule beats a heavy one-off dose.

What it suits

Beds, lawns and landscapes. Garden beds, vegetable and herb patches, established trees and shrubs, and lawns and broad landscapes where the volume of a 10L container actually makes sense.

At planting time. Any new planting. Applied as you plant, it is the single most useful thing you can do to help stock settle into a new position.

Not for. It is a plant health tonic, not a fertiliser, so it does not supply the nitrogen, phosphorus and potassium a feeding program needs. Use it alongside a fertiliser, not instead of one. Delivered Australia wide, with a minimum order of $300 before delivery.
