Why should you buy grass fertiliser, and why is it so important? Fertilising frequently is crucial to maintain soil nutrient balance, as most soils lack sufficient nutrients for grass survival, which eventually absorbs these nutrients.
Lawns resemble humans. A healthy diet and attention are needed to look and perform well. Lush, thick, green lawns need timely, balanced nutrients to thrive. When and how to fertilise your lawn may set you and your grass apart from the rest.
Types of Grass Fertilizer
● Elements Fertilizer
Grass needs water, sunlight, and nutrition. Air, water, soil, temperature, and fertilisers are all crucial. Most lawn fertilisers include phosphorus, nitrogen, and potassium.
● Nitrogen
Nitrogen is essential to photosynthesis. It increases leaf development by increasing chlorophyll production, a photosynthesis molecule. However, it also helps plants combat pests. Nitrogen-deficient plants grow poorly, and yellow leaves.
● Phosphate
Phosphorus is necessary for plant nourishment. It participates in photosynthesis, energy transport, and carbohydrate synthesis and degradation. Because it encourages healthy root development, phosphorus in soil helps grass grow thick and lush. Phosphorus shortage stunts plants.
● Potassium
Potassium regulates plant metabolism and water pressure within and outside plant cells to maintain the healthy grass. Potassium is essential for plant stress tolerance. It impacts cold, drought, disease, and insect resistance in lawns and gardens.
● Bio-Fertilizer
Biological fertiliser comprises live microorganisms for seeds, leaves, and soil. They are crucial to grass soil nutrient cycling. They provide long-term grass fertilisation and health. There are two primary soil microorganism kinds. Each microorganism type improves grass health differently.
● Bacteria
The plant’s root zone receives nutrients from bacteria after the final breakdown. Bacillus Subtilis, a soil-adaptable microbe, may improve soil and reduce grass root infections. It aids grassroots colonisation and pathogen suppression. Daily grass maintenance requires soil biodiversity; beneficial fungus builds strong root systems, maximises fertiliser utilisation, and improves soil conditions.
● Fungi
Commercially utilised mycorrhizae and trichoderma harzianum are the most prominent fungal agents. Roots and mycorrhizae work together to generate thick, lush lawns. Trichoderma harzianum increases soil structure and suppresses fungal diseases.
Organic Fertiliser
Organic fertilisers, such as manure, amino acids, compost, and humic acid, provide plants the following benefits:
- Provide slow-release, safe nutrients for grass development.
- Improve soil condition, retain nutrients and moisture.
- Promote soil microbe growth and nutrient release for soil fertility.
How frequently should I fertilise my grass?
Cool-season and warm-season grasses require altered lawn fertilisation frequency.
● Cool-Season Grasses
Cool-season grasses like perennial ryegrass, bent grass, tall fescue, fine fescue, and Kentucky bluegrass require fall fertilisation due to their fast growth during winter.
● Warm-Season Grasses
Summer-growing buffalo grass, St. Augustine, Bermuda grass, and zoysia are dormant in winter. Overfertilization may burn them, while late spring fertilisation preserves their thickness and colour.
Growth, turfgrass species, and soil nutrient condition should dictate lawn fertilisation method, amount, and time. Remember to use balanced fertiliser to suit turf growth’s nutritional demands.
Knowing all about the ideal fertiliser in your lawn will assist in keeping it in the best condition.
