NEW FORMULA

NEW with added seaweed*

Westland Growmore is a complete, ready to use plant feed, perfect for use all around the garden for flowers, fruit, vegetables, shrubs, and lawns. Its granular format ensures even application and faster nutrient breakdown for efficient plant uptake. The new and improved formulation is enriched with seaweed for even better results.

It releases nutrients immediately, helping bind them in a soluble form that’s readily available to plants. Growmore also supports beneficial soil microbes, aiding the breakdown of nutrients into forms plants can easily absorb. Enriched with natural cytokinins, it encourages strong cell development for faster growth and larger yields.

Ideal for conditioning soils, incorporating into planting areas, or feeding established plants, Growmore ensures your garden stays healthy and productive.

Flowers

Apply 70g/sq.m to the soil surface and lightly fork in. Take care the granules do not touch the plant leaves or stem. Water in well after application.

Frequently Asked Questions

Q. Can my children & pets go into the treated area?

A. Yes, children and pets can go back into the area straight after application

Q. Will my pets or wildlife be attracted to this product?

A. Growmore is a mineral fertiliser and doesn’t contain any organic elements so shouldn’t be attractive to animals.

Q. What should I do if I put on too much of the product?

A. Remove any visible granules and heavily water the area to dissolve and wash through excess product.

Q. Can I use this on my lawn?

A. This can be used all around the garden including lawns, but it is always better to use a fertiliser that has been specifically designed for lawn use such as Aftercut Ultra Green Plus or Safelawn
