Seasol is made from Durvillaea potatorum and Ascophyllum nodosum. Durvillaea potatorum is sourced from King Island and the west coast of Tasmania where the kelp is swept ashore after storms. The kelps are blended together in our own dedicated processing facility near Launceston to produce the wonderful seaweed solution that is Seasol. Seasol seaweed concentrate is a complete garden health treatment that contains plant nutrients, trace elements, alginic acid and other bioactive compounds. Seasol promotes healthy roots, encourages beneficial soil micro-organisms, stimulates flowering and fruiting and helps plants to cope with stresses like heat, drought, frost and pest and disease attack.

PowerFeed is a fertiliser. It has a fish base which is fortified with nitrogen, phosphorus and potassium. The ratio of which is Weight to Volume N 12%: P 1.4%: K 7% respectively. PowerFeed also contains dynamic soil improvers in the form of humic acids. These compounds work at very low rates and are literally like adding liquid composts to the soil. As well as being a quality fertiliser, PowerFeed is also a clay breaker. It stimulates beneficial soil microbial activity and markedly reduces leaching in sandy soils.

Seasol and PowerFeed liquids are fine to use for up to five years.

The date on the back of the container starting with “DOM DD/MM/YY” is the date the product was manufactured.

Seasol and PowerFeed granules (with Troforte) contains beneficial microbes that are activated when exposed to moisture. We recommend storage of open and unused fertilisers for a maximum of 12 months in a moisture free environment for best results upon application. Please keep the lid closed when not in use.

Seasol for Lush Green Lawns is classified as non-hazardous and non-dangerous. There is nothing in it that should be harmful to your pets. We always suggest letting the product go to work on your lawn and dry off prior to your animals going back onto the lawn.

Please refer to our application rate chart under the “How to Use It” tab on each product page

To ensure that the nozzle has fully attached you must first push on firmly,  then push and twist to the right, you will see that the fittings are now fully engaged with a good tight connection and there should be no leaking.

Depending on the water pressure, the contents should disperse within 10 minutes.

PowerFeed with Troforte (slow release) granular range relies on moisture, therefore they will be activated by rainfall and water supplied. The granules remain active from 6 – 8 weeks within the soil. They are affordable and therefore possibly best suited to large applications.

PowerFeed Controlled Release granular range relies on moisture and temperature.  As many plants tend to grow as the soil temperature increases, these granules release more nutrients as they are needed.  These are not suitable for all situations, so if you had winter plants/vegetables you would need to use the PowerFeed with Troforte (slow release)  granular range depending on your climate.

PowerFeed Controlled Release Range is a premium product, so if treating a bulk amount of plants PowerFeed with Troforte (slow release) may be better suited.

With any slow or quick release fertilisers, granules will begin releasing some nutrients immediately upon application and/or watering. Granules that continue to sit against the trunk/main stem can continue to release all it nutrients on it directly and cause some superficial burning. This can cause damage to young plants, but rarely on mature plants and trees. Watering in the product immediately upon application will help avoid this problem, should the granules get on the stem

Another reason is that the nutrient seeking roots of most plants are located away from its trunk and towards its dripline (the line of the outer leaves of the plants). So, it is beneficial to feed where the plants roots can take the nutrients in i.e.- less waste.

This is what is known as “crystallisation” of the potassium liquid in the base of the container.
These are clear and melt when placed in hot water.

Extreme cold temperatures sometimes set off this “crystallisation” especially if you have experienced a cold snap.

*Please note this causes no harm to the liquid itself but, it should not occur and we certainly like our customers to have a bottle that does not have this.*
If your PowerFeed product displays “crystallisation” please contact: ask@seasol.com.au

Seasol Lawn & Turf Starter, Seasol for Lush Green Lawns and Seasol for Buffalo Lawns are all liquids, which are readily absorbed into the lawn and the soil. Therefore you do not need to water them in.

If you are treating your soil with Seasol Super Soil Wetter and Conditioner, please ensure that you do wash it off the foliage, to prevent burning.

PowerFeed Lawn Feed and PowerFeed Buffalo LawnFeed are all granular products and sit on top or just below the lawn and soil. As they contain microbes, they need to be watered in thoroughly  applications, to get those microbes working.

Handy Hint: Application is not recommended on days that may exceed 25°C. Apply in the cool of the day, early morning or late at night.

Yes, Seasol will not significantly affect soil pH, so it is safe to apply to acid loving plants.

PowerFeed is also safe to use on acid loving plants. As a general rule of thumb, apply PowerFeed All Purpose including Natives, but for a more specific formulation try

• PowerFeed PRO SERIES Roses and Flowers (liquid – apply every 2 to 4 weeks)
• PowerFeed with Troforte Rose Food and Soil Improver – including flowering plants (granular – quick and slow release – apply every 6-8 weeks)
• PowerFeed Controlled Release Rose Food and Soil Improver – including flowering plants (premium granular controlled release – apply once every season).

There is no withholding period after applying Seasol or PowerFeed when harvesting fruit and vegetables.

However, with all plant treatments, it is important to wash edible plants before eating.

Yes, because Seasol is virtually phosphorous-free it is safe to use on phosphorous sensitive native plants. You can use it on every type of plant in the garden.

Most PowerFeed varieties are safe to use on Australian Natives. As a general rule of thumb, the best options are:

• PowerFeed All Purpose including Natives (liquid – apply every 2 to 4 weeks)
• PowerFeed PRO SERIES All Purpose  including Natives (liquid includes a soil wetter – apply every 2 to 4 weeks)
• PowerFeed with Troforte All Purpose including  Natives (granular – slow and quick release – apply every 6-8 weeks)
• PowerFeed Controlled Release Plant Food All Purpose including Natives (premium controlled release – apply every season).

Seasol is safe and very effective on all food crops. Seasol increases yields, promotes overall health and even improves flavour! Apply at the rate of 30 ml Seasol per 9 litres of water every 1-2 weeks.

For optimum results use Seasol with PowerFeed PRO SERIES for Tomatoes and Vegetables. Apply at a rate of 50mL PowerFeed per 9 litres of water every 1-2 weeks.

As with all plant treatments, wash edible plants before eating.

Application is not recommended on days that may exceed 25℃.

Due to the natural ingredients in the product, please avoid contact with porous surfaces. If contact is made, wash off immediately with water.

We recommend that when the concentrates are diluted with water the product is used within 24 hours to avoid contamination and maintain the integrity of the product.

If the soil is very dry you should damp down prior to application to help with absorption. If this is a recurring problem and you experience a lot of runoff we would recommend using Seasol Super Soil Wetter & Conditioner (100mL concentrate per 9 litres of water – standard watering can) every 2 weeks until the soil absorbs water. For a maintenance application rate apply 50mL of Seasol Super Soil Wetter & Conditioner concentrate per 9 litres of water) ever 3 to 6 months.

If you soil is absorbing water but needs improvement apply Seasol Liquid Compost (100mL concentrate per 9 litres of water – standard watering) every 2 weeks until the soil improvers. For a maintenance application apply 50mL of Seasol Liquid Compost concentrate per 9 litres of water) every 3 to 6 weeks.

For an easy application Seasol Super Soil Wetter & Conditioner & Seasol Liquid Compost come in hose-on packs.

Due to the natural ingredients in the product, please avoid contact with porous surfaces. If contact is made, please wash off with water.

First thing in the morning or late in the evening. Do not apply Seasol and PowerFeed during the heat of the day. As PowerFeed is a fertiliser it may burn the foliage of the plant or lawn. If fungal problems are an issue, it is best to apply Seasol and PowerFeed in the morning to avoid moisture residue on the foliage overnight.

Yes, Seasol and PowerFeed (liquid) is taken up very effectively through foliage as well as through the soil.

Products that contains a soil wetter such as Seasol Super Soil Wetter and Conditioner, PowerFeed PRO SERIES All Purpose including Natives or PowerFeed PRO SERIES Flowers, Fruits & Citrus, are soil applications only. Please ensure that you do wash it off the foliage, to prevent burning.

750mL Seasol Pots & Planters and PowerFeed Pots & Planters trigger spray and 1.25 Lt PowerFeed Indoor and Potted Plants trigger spray are highly concentrated products, so please only apply to the soil.

CAUTION: Application is not recommended on days that may exceed 25° degrees. 

We recommend initially two applications, one week apart. Apply to the soil, at double the normal rate. Then apply fortnightly, gradually scaling back to the normal rate.

For optimum results it should be applied to the garden every 2 weeks, more frequently (every week) if plants are under stress. Unlike fertilizers, Seasol can be applied all year round, even in winter and at the height of summer.
