Slow Release 18-3.5-8 fertiliser is a quality NPK fertiliser which is ideal for treating amenity areas such as lawns & sports pitches. This product is ideal for areas which require the feed to be slowly released over a 20 week period. Slow release fertilisers help avoid any sudden growth & also reduce the risk of scorch to the grass. It also contains some trace elements which is particularly useful in aiding maximum nutrient uptake. This is a mini-granular compound fertiliser which offers an excellent spreading patten. If you require a slow release fertiliser with a higher amount of nitrogen, consider Prolong 46-0-0

The application rate will depend on how many times you will apply the product, and how much top growth you require If you require a detailed recommendation, please contact us for a soil analysis kit. Apply either by hand or through one of our applicators. If you require a fertiliser with more trace elements, look at Amenity Fertiliser with TE

 *Please note, free delivery is only offered on fertiliser orders over £300 (ex VAT)*
