1. Applying Store-Bought Nitrogen Fertilizers

Find fertilizer that suits your plant’s needs. Liquid fertilizers are usually recommended for potted plants, while granules are more suited for in-ground varieties.

2. Using Animal Manure

You shouldn’t use fresh animal manure because it can contain too much nitrogen and burn your plants’ roots. Instead, allow it to age in a pile, turning it over from time to time, or lay it in a heap in your garden bed a year before you plant anything there.

3. Composting Biodegradable Household Garbage

Waste products can be a source of biomass nitrogen used to improve soil fertility and structure. But not all degradable waste is suitable composting material.


4. Mulching And Composting With Grass Clippings

Grass trimmings are a great source of nitrogen. They have an NPK of 4:2:1, but they do more than just feed the plants. They are an excellent food source for soil microbes that decompose the organic matter and enrich the substrate even more.

5. Using Coffee Grounds

You can scatter the used coffee grounds on top of the soil and water it to make it release nutrients, or add them to your compost for an additional nitrogen boost.

6. Adding Fish Scraps

You can also use fish scraps to make your own fish emulsion. In a five-gallon container or a bucket, mix equal parts sawdust and fish scraps halfway up the bucket. Add a cup of molasses, cover it all with water, and mix it well until combined.

7. Watering Plants With Fish Tank Water

If you reduce the amount of plants in your fish tank, you’ll get a free nitrogen-rich fertilizer perfect for your garden.

8. Planting Legumes And Cover Crops

Legumes and cover crops are known for their ability to fixate nitrogen – transform the nitrogen from air into a form plants can use thanks to certain bacteria around their roots.
