Why Fertilise My Lawn?
Garden lawns need many elements to survive and luckily most of these are available in the soil which they grow. There are 3 macronutrients which plants use relatively large amounts of which may need adding to the soil if you want to maintain a healthy lawn. These are Nitrogen, Phosphorus and Potassium and for your convenience most modern fertilisers will contain a combination of all 3. Phosphorus helps good root growth and plays an important part in photosynthesis, cell division and the plants process of using sugar and starch for energy. Potassium helps with the plants ability to fight disease and overcome drought and winter conditions. Finally and probably the most important is Nitrogen. Nitrogen is required for the plant to create amino acids which are the building blocks for protein, in other words grass needs Nitrogen to grow. Nitrogen is also part of chlorophyll which is what gives green plants their green appearance. A nitrogen deficiency will cause a fall in chlorophyll production and cause your nice green lawn to go yellow. This can be solved with fertiliser.
If any of the above is making you feel faint then don’t worry as fertilisers will always be labelled in the format N-P-K (Nitrogen-Phosphorus-Potassium) which tells you what relative amount of each element is present. In spring when you want to green up your garden lawn after winter you need something that is high Nitrogen; 18-3-8 is ideal. So do yourself a favour and get some fertiliser, or spend the rest of your existence staring at your pathetic yellow lawn thinking of what could have been.
