Commercial growers around the world use the same formulation and they wouldn’t use it if it didn’t work superbly well! Take a look at these two pictures, they show a plant attacked by black bean aphid a) before spraying and b) the same plant just 24 hours later after spraying with Plant Invigorator!
On the QVC website, sadchilli from Blackpool says ’Richard said Plant Invigorator would work. I was a little doubtful, my roses were covered in greenfly. I gave them a blast of the spray thinking nothing would happen. How wrong, next morning not one single greenfly left. Thank you Richard for another fantastic product.’
