The hidden secret behind most good plants is a great root system. I developed Root Booster with three natural ingredients used by professional gardeners to help grow great roots! 

  • Its unique blend of three special ingredients encourage root development, which helps grow stronger and healthier plants. 
  • 100% Natural
  • One application works for the lifetime of the plant. 
  • 1.5kg size tub (this product) treats up to 150 plants in 9cm pots or 15 x 2 litre plants.
  • 650g tub (available here) treats up to 65 x 9cm pots or 6/7 x 2 litre plants.

There are lots of different planting additives on the market. Root Booster is formulated from three special ingredients used and trusted by professional gardeners. It’s 100% Natural and can help any gardener grow healthier, bigger and better plants. Root Booster works for any outdoor plants including all flowers, fruits, vegetables and herbs. 

  • Formulated with  naturally occurring HUMATES. When you water plants, or when it rains, some nutrients will wash out of the soil or compost and are lost to your plants. Root Booster granules absorb some of these, otherwise lost, nutrients and, over time, gradually release them back to the plants roots. In this way, they can make any plant food, including Flower Power, more effective.
  • Plus naturally occurring MYCORRHIZAL FUNGI. These work in conjunction with the plants’ roots to help them absorb more water and nutrients. Remarkably, mycorrhizal fungi can help root systems become up to 200 times more effective. Mycorrhizal fungi are used by commercial gardeners to help grow healthier plants. 
  • And natural starter fertiliser. This gentle mix of natural nutrients helps the root systems establish faster in the first few weeks after planting.

One application of Root Booster LASTS a LIFETIME in the soil and compost. Simply add a few granules around the root system when planting in pots, borders, in the vegetable beds, or when transplanting/moving plants to new positions in the garden. 

  • A 1.5kg size tub treats up to 150 plants in 9cm pots or 15 x 2 litre plants.
  • A 650g tub treats up to 65 x 9cm pots or 6/7 x 2 litre plants.
  • A 50g measuring scoop is included with each tub. 

Questions & Answers

  • Root Booster is easy to use. Simply add the pelleted granules to potting compost or the soil at planting up time. Use one heaped scoop of Root Booster per 2.5 litres of compost. One application lasts all season.

    The granules do change colour from brown to milky white as they absorb moisture from the air. This is the activated stage, it’s the colour it turns once in the soil or compost, but if it occurs in the pack, don’t worry, your Root Booster is still fine to use.

  • A 1.5kg tub of Root Booster will treat up to 20 containers.
  • Root Booster contains three special ingredients:

    • Humates: to boost root growth and to help fertilizers work more effectively.
    • Seaweed extract: a natural bio-stimulant that also conserves moisture in the compost, which means you shouldn’t have to water quite as often.
    • Special plant food: to gently boost plant growth in the first few weeks after potting on.

    This has helped us to establish a new garden in a short time. Thank you

    Have used flower power food for a long time so thought we would try the root booster which has given great results. Really helps the plants establish themselves

    Root Booster is the best. Used it for years. My sister who is a keen gardener cannot understand why my plants are so big, virtually twice the size of hers. Every thing gets planted up with Root Booster, and of course I also use Flower Power. She has now been converted and started using your products. She wouldn’t believe me before and is now starting to see the difference.

  4. Patrick Blake-Kerry

    Much prefer using root booster to using microrhyzal fungi alone. I tend to mix with my potting on compost and the results are stunning for my hanging baskets(@30). Wouldn’t use anything else.
