A strong lawn with autumn fertiliser
September and October are the ideal months to strengthen your lawn. A good quality fertiliser ensures strong root growth so that moss cannot nestle between the grass. However, there are so many fertilisers that we can sometimes no longer see the wood for the trees and it is important to use the right fertiliser. For instance, do you spread a nitrogen-rich fertiliser in the autumn? Then you will be encouraging the grass to grow while it should be resting to prepare for the winter. In this article you will find more information on applying lawn fertiliser.
Fertiliser consists mainly of nitrogen, phosphorus, magnesium and potassium. The latter element is of great importance in your autumn fertiliser. Potassium ensures a good resistance and that is necessary because your lawn has to endure (often) a lot during autumn and winter. Rain, snow and frost can damage the grass.
There are many kinds of fertilisers with different purposes, so that you can continue to fertilise almost all year round. However, autumn fertilisers are highly recommended with many advantages. We offer a quality autumn fertiliser by Viano, namely NPK(Mg)6-6-16(+2)+humifirst. You need only half as much of this autumn fertiliser as of a classic organic fertiliser. With 20 kg you can treat about 400 m². So it is also very economical! The autumn fertilisers by DCM are also highly recommended!
What are the benefits of autumn fertiliser?
- The very high potassium value ensures a dense turf in which weeds and mosses are less likely to establish themselves. It also discourages moss growth, which is typical in autumn. You will therefore find less moss in your lawn in the spring. Do you have a lot of trouble with weeds? Then read our tips here!
- The humifirst in the fertiliser (a rather expensive ingredient) ensures a stronger root development so the grass can absorb nutrients better. It prepares your grass for the coming wet and cold autumn and winter months.
- The added magnesium ensures a fresh green colour.
- Fertilising your lawn not only makes it less susceptible to external weather conditions but also to all kinds of diseases.
- An additional general advantage of fertilising in autumn is that the fertiliser is absorbed more slowly by the soil, which will prolong its effect and you will not need to fertilise again until spring.
Do you have a small garden and no fertiliser spreader available? Then you can also fertilise by hand. Just make sure that you spread the fertiliser evenly so that there are no colour differences in your lawn. Do you need to work on a large area? Then you'd better use a fertiliser spreader.
After fertilising,spray the lawn with water and leave it to rest for 24 hours without treading on it. When watering, also make sure not to spray away the fertiliser granules. Take a look here for our complete watering range!
A few weeks later you can lime the lawn. This will increase the pH value and make the soil less acidic, thus preventing moss growth. The lime will also ensure a good soil structure so that the fertiliser can be absorbed better. It is also advisable to scarify your lawn in September or October so that it can recover sufficiently.
Some more tips from Marcel
- Choose compound organic fertilisers (NPK) as much as possible. This abbreviation stands for nitrogen, phosphorus and potassium. Just like people, your lawn needs all these elements to be healthy. A shortage or excess of one element will not benefit your lawn.
- After fertilising, wait around four weeks before adding lime. Otherwise, the lime will bind with the fertiliser and the nutrients will not be released into the soil.
