Westland Sulphate of Ammonia is an ideal choice for gardeners looking to promote vigorous, leafy growth in their vegetable patches and shrubbery. This premium-grade, fast-acting nitrogen fertilizer is perfect for leafy crops like kale, cabbage, and spinach, providing an immediate nutrient boost that stimulates chlorophyll production. While highly effective at kickstarting seasonal growth, it is a potent formula that requires careful application to avoid over-fertilizing or scorching delicate plant tissues.

The ideal time for application is early spring to encourage initial leafy growth.
This product is better suited for leafy vegetables. For tomatoes, you should prioritize a balanced fertilizer or one higher in potassium once flowering begins.
One 1.5kg box is designed to cover 42 square metres. Aim for an even distribution across this area for optimal results.
It is recommended to keep pets and children off the treated area until the fertilizer has been fully watered into the soil.
It is not recommended for indoor plants as it is highly concentrated and intended for outdoor garden soil application.
If kept dry and sealed, it remains effective for several seasons.
This is likely due to fertilizer burn. Increase the volume of water applied during irrigation to dilute the nutrients in the soil.
The product has absorbed moisture. Gently break up the clumps before use, and store the box in a more arid environment.
For the best application, use a fertilizer spreader or distribute by hand while wearing gloves to ensure an even spread across the 42-square-metre coverage area. It is vital to avoid direct contact with plant leaves, as the concentrated nitrogen can cause scorching. Store the product in its original box in a cool, dry place to prevent moisture from hardening the granules. This fertilizer is compatible with most garden soils but should be applied sparingly to avoid creating an overly acidic environment, as nitrogen fertilizers can lower soil pH over long-term, repeated use.
