Flower Power Plant Food


Flower Power is a plant food with a difference. I developed it to grow more flowers, fruits and vegetables than other plant foods.

The extra high levels of potash help improve the flavour of fruits and vegetables, makes plants more resilient to pests and poor weather, and helps build their winter hardiness.

Many gardeners now rate it as the best plant food they’ve ever used!


Use from early spring to mid-autumn when plants are growing. Can also be used in winter to boost winter-flowering plants.

Product Description

To grow better plants, you need to feed them with a plant food. But not all plant foods are the same. I worked with a leading Garden Scientist to develop a formula based on special feeds used by leading professional growers. My formula contains a unique blend of premium nutrients, seaweed extract, wetting agent and bio-stimulants, and has been tried, tested and trusted by thousands of gardeners to help them grow more flowers, fruits and vegetables compared with the results they achieved with ordinary plant foods.

  • Proven by professionals. Flower Power fed plants have won over 80 Gold Medals and First Prizes at major flower shows, including Chelsea, for plants including clematis, fuchsias, geraniums, begonias, roses, sweet peas, dahlias, aubergines and potatoes.
  • Improves flavour and weather resilience. Flower Power doesn’t just help you grow more. The extra high levels of potash help improve the flavour of fruits and vegetables, makes plants more resilient to pests and poor weather, and helps build their winter hardiness.
  • Works wonders on all plants. Use Flower Power on ALL plants, indoors and out. Even with green (foliage) plants like Hostas. You don’t need to buy other feeds for plants like roses, orchids, tomatoes, azaleas … Flower Power gets great results with them all!  
  • A little goes a long way. Flower Power is super concentrated and goes much further than ordinary plant foods. Just add 5g to 4.5 litres/1 gallon of water.
  • Use from early spring to mid-autumn when plants are growing. Can also be used in winter to boost winter-flowering plants.

Flower Power Premium Plant Food is easy to use, either with a watering can or a hose end sprayer.

I’ve never had much luck with delphiniums until now, they didn’t look that impressive compared with the ones pictured in magazines. But just look at these, I planted them last year with Root Booster and fed them regularly with Flower Power. This year, tons of magnificent flowers. Wow!
