The grasses should be provided with the essential nutrients since these cannot be provided by the soil in all seasons of the year. Therefore, you are required to apply proper fertilisers as per its requirements in different seasons. This is one of the ways of maintaining the health of your lawn.
The importance of using fertiliser:
• Fertiliser promotes the growth of new leaves and roots.
• It controls the growth of weeds.
• Fertilisers help the lawn turf to quickly recover from foot traffic and pest damage.
It replenishes the nutrients that have been removed from the soil through grass clipping and leaching.
Fertilisers are usually available in two different forms – liquid and granular. You are required to choose fertilisers as per the requirement of your lawn.
Granular fertilisers are spread on to the grass and can be easily controlled. These fertilisers are available in the formulations of slow and quick release. Applying the fertilisers in a liquid form helps the plants to absorb it quickly.
The grasses are generally provided with nitrogen fertilisers that are soluble in water. These fertilisers belong to the category of “quick release fertilisers” and usually last for about 3-4 weeks. The fertilisers that are based on slow release formulations can be classified as: Polymer coated- These fertilisers last for 3 months. Sulfur coated-These last for 2 months approximately.
How long a fertiliser will last or how frequently it is applied depends on rainfall. Fertilisers need not be applied towards the end of the growing season in order to avoid unwanted growth.
The percentage of elements upon which, the nutrients of a fertiliser is based, is denoted by a NPK number mentioned on the package of the fertiliser. The three main elements in a fertiliser are namely, potassium, phosphorus and nitrogen.
Nitrogen is responsible for the growth of the leaves (of the grass) and their green color. Potassium protects the grasses against diseases and enhances the development of their roots. Phosphorus is essential for the growth of the roots.
Magnesium, sulfur, calcium are some of the secondary elements present in the fertilisers. Magnesium helps in the formation of sugar whereas sulfur is responsible for the green color. Calcium is encourages the growth of roots.
Manganese, copper, boron, molybdenum, zinc and iron are also present in the fertilisers.
The grass type has to be taken into account for choosing the right kind of fertiliser. Make sure to go through the instructions regarding the use of fertiliser befoCertain fertilisers are used for killing broadleaf weeds, such as dandelions.
Pre-emergent weed killers are the ones that are applied before the weeds can start germinating. These are usually used to prevent the growth of crabgrass. These are mixed with fertilisers in order to be applied on to the lawn.
Post-emergent weed killers are used for killing the actively growing weeds. These work effectively only when applied at the right time. You are required to go through the details mentioned on the package of the fertiliser that you will be using. re purchasing it
