Looking to buy Fertilisers & Plant Food?

Showcasing everything from soil enrichers and growth boosters to specialised plant foods and more, OnBuy’s virtual shelves are yours for the taking. Shop all-purpose plant food and all-purpose fertilisers from the brands you know and love, right here.

Why should I use fertiliser and plant food?

You’ll know if you need to use some fertiliser or plant food as your plants will start to show signs of malnutrition, such as pale green foliage when the nitrogen levels of your plant are low, and dark green veins on pale green leaves when the potassium amount has become minimal.

Don’t worry if you start to notice these signs on your plants - it just means that the plant has used all of the natural nutrients within the soil where it was planted to create its own plant food and now needs some help from you!

Use fertiliser and plant food to prolong the life of your plants and to ensure they stay healthy and thriving - here at OnBuy, we’ve got an extensive range of fertilisers to boost your plant's strength, in addition to liquid plant food and organic plant food - so you’ll be covered no matter the plant you’re feeding or the soil it’s living in!

Not sure exactly what you're looking for? Read our guide to fertilisers and plant food and you'll know in no time!
