For best results, apply fortnightly during the warmer months. During cooler months, apply less often and/or at lower strength. Best applied all-year round to continue improving soil and feeding microbes.
Agitate well before use.
As there are many conditions that effect the exact amount needed and the frequency of application for each product, there is no one fits all solution.
There are several ways our liquids can be applied:
Watering can: mix the amount suggested (typically 10‐30ml)/9 litres of water. Spread evenly across area to fertilise.
Hose‐on Bottle (Seasol/weed ‘n feed etc.) or hortex sprayer: mix the minimum amount of water with the product/s to allow you to cover the required area/s. For example, for my front yard, using an old weed n feed hose‐on bottle I add 100ml of each Seaweed Secrets, Activ8mate or Activ8EXTRA and Natures Soil Wetter, then top up with enough water to allow you to evenly cover it using the hose‐on bottle (I add about 600ml water), then evenly hose‐on.
Pressure/knapsack sprayer: You need about 15 litres (a little more or less won’t hurt) of water to be applied per 100m2, so take that into consideration when applying. If you have a smaller sprayer, either do several smaller applications i.e. covering 50m at a time and repeat until the entire area is covered, or over a larger area spray with the required amount and if you haven’t used 15 litres/100m2, give a light water‐in. If using a Hortex sprayer on setting 2 without the restrictor, you shouldn’t need to add water, but if you do, just add as little amount to cover the required area.

I've been using Plant Doctor liquid fertilizers for some time now, and I can't fault them. They are of a high quality, and make my lawn look exceptional. I used Activ8 previously, and this new EXTRA seems to work even better!

Giving the grass some love.
By: Stephen on 20 December 2022
I started using this about a week ago after adding Nature's Soil wetter to my lawn. Wow..... What a difference it makes. My grass in responding so quickly. Before it was hard to get it to do anything. This stuff is like gold in a bottle. I had some dead and dying areas of grass but now they are lush, green and filling in again.

Great adjunct liquid
By: Andrew on 11 February 2022
Added this into my foliar program for the 2021/22 season and have been happy with it. It’s great to have a turf product with a bit more P and K for foliar application.
Great value !!
By: Vincent on 20 January 2022
This stuff works out way cheaper per 100m2 compared to the stuff you can get from the green shed. Works a treat. Lawn has never looked better. Free shipping with orders over $59 is the icing on the cake.

The product worked almost overnight. This is definitely the go to product to use to put the greeness back into the grass.

This is a boosted version of Activ8mate - I was happy with the original but if you want some more push with extra nitrogen then this is the one to get.

Extra Kick liquid fert
By: Anferny on 11 June 2021
Having used the active8mate product which was fantastic.
So decided to get the active8extra product to see the performance you get. Everything just took off in growing despite the cold condition we are experience in winter condition, so definitely another product to add in your collection for that extra kick.
Works all the time!
By: Shoua on 4 June 2021
This is my 'go-to' liquid lawn fertilizer that I use every month to keep my lawn in 'tip-top' shape! It's a well rounded fertilizer that can also be used on plants and trees and extremely beneficial during Winter given that granules don't do a good job in the colder weather. Highly recommend for all lawn lovers and rest assured Activ8EXTRA will differentiate a great lawn from a good one!
By: Jon on 2 June 2021
I use to always use seasol on my lawn, since being told about Activ8extra I've been converted and so have my mates that I've told
Can notice the difference
By: Alana on 13 May 2021
Great product, can definitely recommend this as I can see larger leaf size and faster growth on my indoor plants.

Great Liquid Fertiliser
By: Mark on 15 June 2020
Easy to apply product using a hortex sprayer and gave the yard a really good pop. I teamed this up with the granular fert, no issues and great colour. I get a lot of great comments from friends and family that turn up to the newly invigorated lawn!

First time owning lawn. Gave the team at plant doctor a ring and they supplied me with a wealth of information. Products turned up quickly.
Will definitely be getting more 8 weeks difference been using stimulizer, activ8mate, soil wetter, seaweed secrets and champion fertiliser. Was super fast delivery.
Amazing products!! The results are excellent and the prices are even better! Postage was only 2 days as well. Highly recommended!
Only have great things to say about Plant Doctor. Organic products and a competitive price, fast shipping and easy to contact with questions. Have had great results with the special mix for lawns, and my plants (indoor and outdoor) love the seaweed secrets. I am excited to test out some of the animal products soon!
