How to use Soluble Fertiliser

Granular products; our Spring, Summer, Autumn and Winter Fertilisers are the equivalent of your breakfast, lunch and dinner and therefore should be your main fertiliser products. A soluble food is a snack like you would have a banana or Kit-Kat. Therefore, use this product to supplement granular feeds from late spring to early autumn, not to replace them.

When not to use soluble fertilisers

Soluble feeding is feeding via the leaf as well as the roots. This means:

  • Using it on seedlings is not very effective and could burn the delicate young shoots
  • Can burn mature grass very easily in dry conditions
  • Doesn't work well in cold conditions
  • Doesn't have the right balance of nutrients for use from late autumn to early spring

The Soluble fertiliser was easy to mix and applied from a sprinkle watering can.
It kept the lawn looking good compared to my neighbours’s lawns.
If your lawn looks tried thus will help the lawn .
