To grow better plants, you need to feed them with a plant food. But not all plant foods are the same. When developing Flower Power Plant Food I worked with a leading Garden Scientist to develop a formula based on special feeds used by leading professional growers. My Flower Power 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. Scroll down to see their amazing results and discover why Flower Power is rated by many gardeners as  the best plant food they’ve ever used’.


The benefits of Flower Power Plant Food


  • 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, make 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.

If you’d like to read how other growers around the UK have got on using Flower Power, you can read why Susan and Keith consider Flower Power their magic potion here, or why Flower Power is the winning plant food here.

Flower Power is easy to use, either with a watering can or the Flower Power Hose End Sprayer. Using my Easy Shaker to thoroughly dissolve the Flower Power granules before adding to a hose end sprayer, also helps to eliminate the risk of blocking the sprayer with un-dissolved granules. A 5g measuring scoop is included with each pack.

Flower Power is now also available as an organic liquid plant food.

This 1.5kg tub of Flower Power makes makes 1,350 litres (300 watering cans) of feed.
A 750g pack of Flower Power makes 675 litres (150 watering cans) of feed.
A 475g pack of Flower Power makes 427 litres (95 watering cans) of feed.

Questions & Answers

    • Use 5g (one measuring scoop or level teaspoon) of Premium Plant Food per 4.5 litres (1 gallon) of water. When using a watering can, I prefer to put the Premium Plant Food in the watering can, pour in the water, then stir well.
    • For young seedlings and plug plants, prior to potting on, use Premium Plant Food at half the normal strength.
    • From March to May, feed your plants once every two weeks. From June to September, for the very best results, feed your plants twice a week.
    • For top yields with greenhouse tomatoes, I recommend feeding three times a week once the first truss has set.
  • Flower Power Premium Plant Food contains:

    • NITROGEN – for healthy leaves and shoots
    • PHOSPHATES – for strong roots
    • POTASH – for better flowers, fruits and vegetables
    • ESSENTIAL TRACE ELEMENTS – vital for healthy growth
    • SEAWEED EXTRACT – to stimulate natural growth
    • WETTING AGENTS – to help all the above special nutrients reach every root, every time

  1. Monika Spademan (verified owner)

    Flower Power was recommended to me after I was bowled over by a friend’s garden! I’ve been using it for 3 years now and I wouldn’t use anything else! The results are very visible and it is good value! I love it as it is easy to use. It has all the nutrients for all my plants and vegetables so I have not got a garage full of other plant food! I have over 50 planters and containers and a large garden! I am constantly recommending it as I am very passionate about the product!

  2. Patrick Blake-Kerry

    Used Flower Power for several years on my 20 hanging baskets and 20+ containers in a sheltered housing complex. The results are simply stunning, and, quite frankly, I wouldn’t dare use anything else in case the standards dropped. Visitors regularly take photos of our display and fellow residents just love them. Surfinias, Begonias, Geraniums, Dahlias simply thrive. Also use on my greenhouse crops to fantastic effect.

  3. Paul Gosling

    This is my second year of using Flower power . I get comments on my baskets , like how do you get so many flowers and your baskets are amazing. Then I get the big question “how do I do it “ I just say a lot of hard work and some help from my mate Richard.

  4. Karen L

    Flower power is the best ever. Never use anything else. The plants look healthy and well structured.

  5. R Smyth

    This plant food allows my plants compete with Arnold Schwarzenegger in size and strength, all my plants that have been fed with this have grown exponentially faster , larger, healthier, stronger, vibrant etc. it is better than any other product i have tried, the results speak for themselves.

  6. Kim (verified owner)

    I have used this for several years and the results are always amazing. I actually did a comparison test last year using another well known product and Flower Power and the flowers in the Flower Power hanging basket were significantly bigger. Great product.

  7. Lisa

I thought nothing would improve on the fertiliser that I've been using since the 1970’s. I've been astonished by the results that FLOWER POWER has in my garden, and it’s even improved the cropping on a 40-year old apple tree. – Derek Swann
