Lawn fertilizer for fast-acting results, long-lasting performance, and special applications
For lawn care, choose from variants with NPK analysis, fast-acting or long-lasting performance, organic or mineral composition, as well as products for lawn establishment/new lawns, fall, iron, moss, and weeds. Pack weight and the stated coverage area help identify the right option.
Choose lawn fertilizer by purpose
Lawns differ in how they are used, the season, and the care they need. Information about the type of performance, NPK ratio, composition, and coverage area helps classify the available variants. Product names and product cards refer to fast-acting performance, long-lasting performance, starter products, fall products, iron products, and weed or moss control products.
Weight and the stated coverage area always belong together. A 3 kg product with weed control is listed for approx. 150 m², while a 25 kg product with fast-acting performance is listed for approx. 900 m². These pairings make the size selection understandable without mixing details from different products.
Fast-acting, long-lasting, or both
For products with fast-acting performance, this designation appears alongside other features such as NPK ratio, weight, and coverage area. A 25 kg complete fertilizer lists NPK 21+6+12 and approx. 900 m². Another 10 kg variant with the same NPK analysis appears in the product list. Other cards combine fast-acting and long-lasting performance. Depending on the product, long-lasting variants are described as lasting 12–14 weeks, up to 100 days, or up to three months. These time periods belong to the individual product card and are not a uniform category value.
Fast-acting performance as a selection criterion
With fast-acting performance, NPK analysis and coverage area can be compared together. This is more useful for small, medium, and large areas than weight alone, because the same performance designation can be associated with different pack sizes.
How to assess long-lasting performance
Long-lasting products are available with different formulas and compositions. Examples include 20+5+8 at 25 kg for approx. 830 m² and an organic-mineral variant at 15 kg. Performance duration, area, weight, and composition of the same variant are what matter for classification.
Reading NPK and composition
NPK analysis provides a basis for comparison in the product cards, but it should be considered together with the purpose and coverage area. The range includes 21+6+12, 9+3+6, 6+5+12, and 20+5+8; a mineral long-lasting fertilizer lists 16+7+16. The formula should therefore always be considered together with the performance type and coverage area of the same variant.
Organic, mineral, or organic-mineral
Organic variants are identified as organic or bio. One example lists 20 kg, NPK 9+3+6, and approx. 400 m². Mineral and organic-mineral products form separate selection points; the product list also includes a 10.5 kg organic variant with NPK 8+3+6.
Do not consider NPK in isolation
When choosing, a single number is therefore not the only deciding factor. The meaningful combination is the designation, NPK ratio, weight, and the coverage area stated for that exact product. This keeps products with different formulas and application details clearly separated.
Consider the season and purpose
For lawn establishment and regeneration, starter lawn fertilizers are identified as a separate application purpose. One product card describes 25 kg as a starter for both situations; another starter card lists 25 kg, complete fertilizer, and 700 m². These details help classify a product when establishing a new lawn or regenerating an existing area.
Seasonal categories include spring, summer, and fall. A fall lawn fertilizer is listed at 5 kg, NPK 6+5+12, and 140 m²; other fall products are identified as organic or as 20 kg with approx. 500 m². The season, composition, and coverage area should come from the same product card.
Starter lawn fertilizer for lawn establishment and regeneration is described as an individual product variant for this purpose.
Distinguish iron, moss, and weeds
Granular iron fertilizer is described in the product cards with a particle size of 2–4 mm, 25 kg, and approx. 900 m². A 5 kg variant is identified as lawn fertilizer with iron for moss control. This distinguishes an iron specification from a product whose name explicitly mentions moss.
Products with weed control are described for lawns and broadleaf weeds. The range includes, among others, 3 kg for approx. 150 m², 5 kg for approx. 250 m², and 12 kg for approx. 600 m². One product card also lists an application rate of 20 g/m², an application period from April to September, and exclusion of the seeding year. These details belong to the relevant product and not to every lawn fertilizer variant.
Match pack size and area
The product cards show packs from 3 to 25 kg. Stated areas range from approx. 150 to approx. 900 m² depending on the variant. In between are examples such as 250, 400, 500, 600, 700, and 830 m². The range describes the individual listing; it is not a general coverage figure for every pack size.
For size selection, the combination of weight and stated coverage area is therefore decisive. 5 kg may be paired with approx. 250 m², while 10 kg may be listed with approx. 500 m² depending on the product. Even for 25 kg, the figures differ, for example approx. 500, 700, 830, or 900 m². This keeps the selection focused on the specific variant.
Subcategories by focus
The subcategories group recurring selection criteria. NPK, long-lasting performance, fall, and iron fertilizer for moss control are separate starting points, each with its own product selection.
Application and related garden topics
For application, one product card mentions hand application and broadcast/push spreader use. The product list also includes a broadcast spreader with a 45 cm spreading width and a hand spreader with a 3-liter capacity. These accessory details help with work planning without changing the fertilizer features.

Frequently asked questions about selection
What is the difference between fast-acting and long-lasting performance?
Fast-acting and long-lasting performance are different product designations. Some variants combine both. Depending on the product, the cards state 12–14 weeks, up to 100 days, or up to three months; this duration always belongs to the relevant variant.
Which pack size fits the stated area?
The decisive factor is the pairing of weight and coverage area. Examples range from 3 kg for approx. 150 m² and 5 kg for approx. 250 m² to 25 kg for approx. 900 m². The stated area may differ between products with the same weight.
When is starter lawn fertilizer suitable?
Starter variants are specifically described for lawn establishment and regeneration. Another product card lists the starter as a 25 kg complete fertilizer for 700 m². These details distinguish the starter purpose from fall, iron, or weed control variants.
How do organic, mineral, and organic-mineral variants differ?
The composition is identified differently in product names and cards. One organic product lists 20 kg and NPK 9+3+6 for approx. 400 m²; other entries are mineral or organic-mineral. Weight, NPK, and area remain additional points of comparison.
When is a product with iron or weed control relevant?
Iron variants are identified by an iron or moss reference; one granulate lists a particle size of 2–4 mm and approx. 900 m². For weed control products, lawns, broadleaf weeds, and, depending on the card, area, application rate, and period are the key details.
In one sentence: First identify the purpose and performance type, then compare the NPK analysis, composition, weight, and coverage area stated for that exact variant.
