What is the difference between Seasol and PowerFeed?

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.

What do I do if my pet drinks Seasol?

If your pet drinks Seasol, it would be advisable to supply him/her with plenty of fresh water to dilute the contents in the stomach. Due to its alkalinity, gastric irritation may result if significant quantities of the concentrate are ingested. In this case please contact your vet. Please find our Seasol Safety Data Sheet at the end of the Seasol Product page, under SAFETY & ANALYSIS or go to https://www.seasol.com.au/home-garden/safety-data-sheet/

Seasol or PowerFeed has stained my pavers, what can I do to get it off?

Because of the naturally occurring colour of kelp, fish and humate, Seasol or PowerFeed can stain just like beetroot and red wine. If you do spill Seasol or PowerFeed on concrete or pavers you should rinse it off ASAP to avoid staining. If you have an existing stain, try applying a product called ’30 Seconds’. It is a Sodium Hypochlorite based cleaner. Other customers have had great success removing Seasol or PowerFeed stains on pavers and concrete with this product. Remember to test this product on a small patch to ensure it doesn’t damage the pavers.

What is the difference between PowerFeed slow release granular range and PowerFeed controlled release granular range?

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.

Why do you keep PowerFeed granular fertilisers away from the main stem or trunk?

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.

My PowerFeed liquid product has what appears to be ‘glass’ in the bottle?

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

2022-08-29T13:16:32+10:00

Do you water your lawn after applying Seasol or PowerFeed lawn products?

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.

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.

2021-07-28T12:22:47+10:00

Can I put Seasol on dry ground?

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.

2022-07-15T12:46:51+10:00

What is the best time of the day to apply Seasol and PowerFeed?

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.

2021-07-28T12:16:36+10:00

Can I apply Seasol and PowerFeed to the foliage as well as the soil?

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. 

2021-07-28T12:16:06+10:00

How often should I apply Seasol?

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.

2021-07-28T12:15:01+10:00

Does Seasol contain a lot of salt?

Seasol is made from two species of seaweed – Bull Kelp (Durvillaea potatorum), Chile Bull Kelp (Durvillaea Antarctica) and Knotted Kelp (Ascophyllum nodosum), both which come from the sea. The sodium and chloride levels are very low because the kelps do not actually absorb the salt.
