There are a variety of options to increase the nutrient level in the lawn and grass.
Some of the most popular options include:
- Compost (green material)
- Fish, bone, and blood
- Manure (cow or chicken)
- Mulch mowing
- Seaweed (solid or liquid form)
Each of these organic lawn fertilizers can provide a certain degree of benefit. Organic products are starting to be more favored for the reasons or green issues and economics. Plus, because there is a higher demand for fertilizers to promote the garden, the prices are starting to increase.
Green waste does have the benefit of being widely available because it can be recycled and there is constantly a source of manure and compost products.
If planning to use self prepared compost it is critical that it is given enough time to fully decompose into a rich humus material. Once broken down by bacteria, the original compost ingredients are ready to be used as a type of plant food. If the decomposing process isn’t fully complete, it will continue even after before applying to the lawn or garden. This can have a negative impact of limiting the amount of oxygen that reaches the root system. So, make sure to only use the material that is 100% aerobically decomposed.
The advantage of using organic materials
- Slow or long-term release
- Minimizes issues with fertilizer burn
- Great at releasing micronutrients not often seen with store-bought fertilizers
- Gives the benefit of adding organic material to the soil
The disadvantage of using organic materials
- Needs to be applied in higher volumes to have the desired effect
- Organic manure and matter will increase the population of worms — this can be positive or negative
- Likely to be quite smelly when first applied
More work is required for applying top dressing or similar treatments
- A surface that has a lot of heavy compost or organic material is likely to hold water and prevent it from running away, which can leave the grass quite soaked
Preferred lawn fertilizer
A highly recommended fertilizer for the lawn is the chicken manure. While this can be quite smelly, it is great for promoting the health of the lush-green lawn. Plus, it is a reliable option to help encourage more worm or bug life to deter the destructive pests. A yearly application at the start of the season is usually enough. The best time to apply is when the temperature is cool, to help control the potential smell.
Using a mulch mower
A mulching mower gives the ability to naturally provide fertilizer while mowing the lawn. They are built to cut the clippings into small size pieces to avoid issues with large clumps on the lawn area. Plus, leaving the fine layer of grass clippings on the lawn can help to hold more water, which is especially helpful during spells of dry weather. A further benefit is the ability to encourage worm activity and this will help the general lawn and root structure.
