How to make your own natural fertilizer?

Fertilizer is necessary to ensure good growth and health of plants, the vegetable garden and even its lawn. Rather than buying chemical fertilizer, why not make your own fertilizer?
I myself have tested several fertilizers for my garden, so here are my best recipes for making a natural fertilizer.
1. Make a natural fertilizer with coffee grounds
A super simple way to make your own natural lawn and plant fertilizer is to use coffee grounds.
Coffee grounds are an excellent source of phosphorus and nitrogen, two essential ingredients for maintaining the health and growth of your indoor green plants and vegetables in the vegetable garden.
- Get into the habit, every morning, of keeping the coffee grounds in a jar that you place in the refrigerator afterwards.
- Incorporate coffee grounds regularly into the soil of your green plants and vegetables in the garden.
- Also mix coffee grounds in a watering can filled with water and water your garden and even your lawn.
On the other hand, avoid adding this coffee fertilizer during the flowering period, because the nitrogen promotes the growth of the leaves to the detriment of the flowers.
Use tea bags as fertilizer too!
If you are rather looking to make a fertilizer to facilitate the flowering of your plants and flowers then opt for tea instead.
Make a second infusion with your used tea bags, which you will then add to the water for watering your plants. Tea residues contain carbohydrate, an element that promotes beautiful flowering.
2. Make plant food with eggshells
Another ingredient to keep at home to make your own natural plant fertilizer is eggshell.
Eggshells are rich in calcium, magnesium and potassium, so it’s a great natural fertilizer for your plants!
- Wash the eggshells and let them air dry for several hours.
- Grind the shells into very small pieces and sprinkle them over the soil and potting mix of your plants.
You can also boil the shells in water that you filter and then let cool before watering the soil of your plants, vegetables and shrubs with this liquid fertilizer.
3. Wood ash as lawn fertilizer
If you are looking more specifically for a natural fertilizer to have a beautiful lawn and beautiful vegetables, then wood ash is the solution!
Wood ash is an excellent natural fertilizer, as it is rich in potassium and phosphorus.
- Collect and store the ashes of cooled wood in the garden.
- Apply a thin layer of ash to the lawn and garden.
- Rain or watering will take care of dissolving and nourishing the soil with this ash.
It is important not to put too much on the ground because you risk suffocating the lawn and the plants. A very thin layer of ash is sufficient as fertilizer.
4. Nettle manure as fertilizer for the vegetable garden
Although it is considered by many to be an undesirable plant, the nettle can become very useful in the garden to nourish the plants and vegetables in the vegetable patch.
- Just make a decoction or nettle manure by letting the plant macerate for a few days in a bucket of water.
- Thereafter, dilute this manure with the irrigation water, and apply it to the base of your fruit trees, in the vegetable patch or in the flower garden.
In addition to being a natural fertilizer, nettle manure can be used as a natural insecticide against aphids, but also against mites.
5. Homemade Houseplant Fertilizer Recipe
Did you know that you can use the cooking water from your vegetables to make a natural fertilizer for your indoor green plants, but also for the garden?
Here’s how to make and use this plant food:
- Collect the cooking water from your vegetables, pasta or eggs and let cool.
- Add 1/2 cup of coffee grounds to the water, mix well and strain the solution.
- Water your green plants and garden vegetables with this solution.
Water your plants and vegetables with this fertilizer once or twice a week to restore vitality to the plants.
6. Make a fertilizer with dried seaweed
You don’t live too far from the sea? Seize your chance and during your next walk on the beach take the opportunity to pick green algae.
Rich in potassium, calcium and magnesium!
As green seaweed is rich in magnesium and potassium, it can be used as a natural fertilizer for your green plants, lawn, vegetables and flowering plants.
- Place the seaweed in a heap at the bottom of the garden, to avoid being bothered by the smell it gives off.
- Let them dry for several days in the sun and grind them.
- Spread the dried seaweed in the garden to feed your plants.
Make a Natural Liquid Seaweed Fertilizer:
You can also make a liquid seaweed fertilizer to water the soil around your plants and flowers. Here’s how:
- Leave 2 to 3 kg of seaweed to macerate for several days in a large tank filled with water (10 liters of water).
- Mix regularly and filter the solution after 4 to 5 days of maceration.
- Spray this liquid fertilizer in the garden, vegetable patch and even on the lawn.
7. Homemade lawn fertilizer
Finally, I share with you an easy-to-make and above all very effective lawn fertilizer recipe for having a beautiful lawn this summer!
- Put in a large bucket of organic compost at 1/3 of the bucket.
- Fill the bucket with water and close it with a lid or a tarp (well sealed).
- Leave to macerate for 5 days, filter the mixture and dilute with water before use.
You can spray this natural fertilizer diluted with water 2 to 3 times a summer to promote and accelerate the growth of your lawn.
