Having recently moved house, my potted gardenia was sulking badly - loss of glossiness on the leaves and buds dropping. I had an online chat with Brian from the Aussie Gardener store and following his advice purchased the Amgrow Harvest Organix. The product arrived really quickly and the gardenia is starting to look much healthier - I will apply again in 2 weeks. Great product and great company to deal with.

I bought Amgrow Organix Harvest 500 mL and used it first time on my vegetable garden. Yet to see the effect. While it is a concentrate, the 500 mL bottle (about 100 L when diluted) is just enough for watering the garden one time (recommended to apply 1 watering can per square metre of soil area). They also have Nutrafeed All Purpose Fertiliser 500g which will make about 500 L when diluted, so that looks like more cost effective product.

Having watched the fabulously informative video series these two amazing gardeners produced, I bought this and many more products from their online store. I could not be more pleased with the range, prices, delivery and packaging of the products. So convenient and confidence in the quality is complete. It's SO good to support a small local company doing great work!

Very good product, great price
Wouldn't use anything else when growing vegetables.
I bought the small bottle to see what it was like. I have only used it for a short time (less than a month) but so far it certainly has picked up all the plants I have put it on and the garden is looking great, particularly the hedge plants! I have now ordered the bigger container.
This organic fertiliser is effective. I loved watching my seedlings power up after a feed. Great price too.
As we our patch has grown Harvest has proven a must have all round.Thanks Aussie Gardener
Harvest gives the plants the nutrients they need to blossom
Amgrow Harvest Organix is an excellent product. I have used it on plants and my dwarf lemon tree that seemed to be a little in need of TLC. After 2 applications about two weeks apart, I can see the results ! New shoots very healthy and I have blossoms on the lemon tree !Definitely to be recommended ! Thanks to Aussie Gardener for stocking such a great product.
