The Simple Guide to Lawn Fertiliser
There are a huge array of lawn fertilizers on the market today.
How do you know if you are buying the right one and getting your value for money?
All fertilizers, whether they are for lawns or plants, are measured by their nitrogen, phosphorus and potassium content. This is quoted on every packet as a % of N P K.
N – Nitrogen
Nitrogen helps the plant or lawn produce lush leafy growth.
P – Phosphorus
Phosphorus helps the lawn below ground enabling it to produce a strong healthy root system. This is essential to help a new lawn get established. It also helps plants with flower and fruit production.
K – Potassium
Potassium gives plants strength to fight disease and helps with the overall health of the plant or lawn
All Purpose Weed, Feed and Moss killers are great products if your lawn is in great all round condition. They help your lawn to tick over, keeping moss in check and perhaps putting an end to a few daisies and broadleaf weeds you might find in your lawn.
Sadly, in our experience, few domestic lawns are that healthy and actually require a bit more oomph to get them up to scratch.
Weeds in the Lawn
If you have a few too many weeds in your lawn, it is best to go over it with a selective weed killer. This will kill the weeds but not the grass. A good example of this is Weedol/Verdone Lawn Weed Killer. Use a PUMP ACTION SPRAYER if your lawn is of a reasonable size.
For Moss in the Lawn
Use a fertiliser that has added Iron (moss’s biggest enemy).
The higher the N Nitrogen % on the packet the more lush, thick and green your lawn will be. So you might see on the back of the packet 20-5-5, meaning 20% nitrogen, 5% phosphorus, 5% potassium. This is a great summer fertilizer and LAWN BUILDER is a highly recommended example of this.
If you are feeding the lawn in early spring, a lower Nitrogen % with a higher potassium content is needed. Look, for example, 6-5-10 which is 6% nitrogen, 5% phosphorus and 10% potassium. This will ensure that you do not promote much top growth, but give plenty of feed to the roots. This will keep the plant healthy. You can also use an autumn feed in spring as they usually contain iron to control the moss. Some good fertilisers for spring or autumn are LAWN SAND and LAWN BUILDER AUTUMN and AUTUMN FEED AND MOSS KILLER Spread them using a HANDY SPREADER which gives you lots of control when fertilising your lawn.

When selecting the fertilizer check the m2 coverage. Pace out your lawn from one side to the other and then one end to the other. Multiply the two, giving you the square meterage of your lawn.
