Plant Invigorator Concentrate 500ml


(2 customer reviews)

This is quite remarkable. It’s a friendly, non-chemical way to beat plant pests and feed your plants each time you spray them. And it’s the formula used and trusted by 100’s of professional growers.

A few years ago, I was in Guernsey visiting Raymond Evison, the world-renowned breeder and grower of clematis. He told me about a special product that he, and hundreds of top growers, were using as a plant tonic that also controlled plant pests. During my visit, I met other growers all of whom also used on a variety of plants including tomatoes, cucumbers and freesias. All of the growers highly recommended it. I then tested it at home, loved it, and then worked with the manufacturer to introduce my own version. For best results, do what the professionals do, spray once a week, on the top and undersides of the leaves, applying enough spray until it starts to drip off the leaves. If the plant is suffering from a pest attack, spray every three days for a fortnight, then once weekly from then on.

  • Three in one action. Helps control plant pests at the same time as feeding plants through their leaves. And helps control powdery mildew disease.
  • Works by physical action. It’s the non-chemical way to control many pests including greenfly, blackfly, whitefly, mealy bug and scale insects.
  • Based on the professional formula. As used and trusted by some of the leading growers and gardens in Europe.
  • Safe for pets, kids bees and ladybirds. And it can be used on edible plants like herbs, fruits and vegetables that can be harvested straight after spraying.
250ml double concentrate bottle (available here) makes up to 25 litres of dilute spray.
500ml double concentrate bottle makes up to 50 litres of dilute spray.

    I just wanted to let you know how effective I have found your “Pest Control” product. Last year I bought some gorgeous lilies, and although they were magnificent they became decimated with red Lilly beetles. I tried a lot of stuff, some quite pricey, all to no avail, I even tried picking them off, which didn’t give any better results! They just kept coming back!
    So when the lilies started to pop above ground this year, the little beetles were there too, once again I tried the stuff I had previous bought, but still no effect. Then I saw RJ pest control on QVC, he said it would get rid of them, I was sceptical, but bought it.
    Oh my gosh, one application later and the little blighters are gone, nothing since! It’s been over a month now so I’m well impressed.
    A brilliant product, definitely 5 Star

    I have used this plant invigorator for several years now. It was the 1st of it’s type I saw advertised and wouldn’t be without it in my greenhouse. Especially good on cuttings. I use it in my hydropod daily to moisten up the cuttings and they just benefit so much – they appear to maintain their growth as if still attached to their parent plant. I wouldn’t be without it.
