Jeff Holman lists the chemical-free organic fertilizers that are ideal for an organic kitchen garden and will leave your plants blossoming gorgeously.
Chemical fertilizers with high concentrations of nitrogen, potash, and phosphorus—the three essential nutrients that plants require to grow—have been recommended to gardeners for years. However, many chemical fertilizers, according to Ben Raskin of the Soil Association, contain more than quadruple the quantity of nutrients that your fruit and vegetables actually require. Raskin explains that this is an issue since the extra minerals end up in water sources that are utilized by both people and animals after being washed away by rain and irrigation. This poses a serious pollution danger. Given the abundance of environmentally acceptable alternatives, most of us don’t require turbo-charged chemical fertilizers because, unlike farmers, we aren’t growing food for sale. Here are the top five.
Kelp Potassium and a little amount of nitrogen are present in kelp-based fertilizers, but their main advantages are the long-term effects they can have on your plants. It has been demonstrated that kelp encourages soil growth, which helps plants flourish and boosts overall production. Additionally, it enables plants and crops to adapt more readily to temperature extremes like ice and extended periods of sunlight. Although you can purchase kelp at garden centers, gathering and composting it yourself is the most affordable method to acquire some.
cow feces Cow manure, the most popular kind of muck, is nutrient-rich and feeds both soil and plants. Applying fresh manure directly to plants, as with chicken manure, might cause them to burn, therefore you must properly compost it before using. If you’re applying it on fruits and vegetables, it’s worth looking for cow manure that has been raised organically; otherwise, you run the risk of giving your plants, among other things, chemical antibiotic residues.
adobe meal Although it does contain a fair quantity of nitrogen as well as some potassium and phosphorus, alfalfa meal is another plant-based fertilizer that benefits the garden in subtle ways. The true advantage of alfalfa is that it enhances soil quality and makes it possible to produce more nutrients for plants to consume, which eventually leads to an increase in plant development. Most garden centers sell it, and it works very well on roses.
Limestone Generally speaking, limestone fertilizer is a good addition to soil, however the advantages vary depending on where the stone came from. Limestone provides calcium, which aids in general plant growth, and magnesium, which promotes stronger, healthier plants. Limestone is used to adjust PH levels in soils with high acidity. Before applying limestone fertilizers, it’s crucial to analyze the soil’s acidity levels to establish how much, if any, is required. chicken poop More nitrogen, potassium, and phosphorus are found in chicken poop than any other sort of manure, and calcium and magnesium are also abundant in it. You can purchase the manure as pellets or ask a neighboring farmer for leftover chicken muck to compost yourself. The high nitrogen content of fresh manure can burn plants, so you must make sure it has been adequately composted before using it. In order to keep the organic and nutritional value of your fertiliser, as Raskin emphasizes, make sure it comes from a free-range chicken farm.

REVIEW Freely Grow Your Own Food According to Andy McKee, Dave Hamilton’s book is filled with helpful tips and includes everything you need to get started living a more independent lifestyle.
How can indoor plants be naturally fed?
When generating your own fertilizer, it’s crucial to understand each of these nutrients, where to find them, and what they can aid with.
Here are several natural methods you may use around your home to give your houseplants these necessary nutrients, among others:
Crushed Eggshells
Calcium is a crucial ingredient for your plants’ capacity to produce new cells and, consequently, for the plant’s overall growth.
By chance, eggshells have a high calcium content. They also include minute amounts of phosphoric acid, zinc, and nitrogen.
It is very easy to use eggshells as fertilizer for indoor plants. Before using or storing your shells, make sure to rinse them to lessen the chance of mold growing.
The simplest method is to freeze your eggshells until you have around a carton’s worth to use as fertilizer for indoor plants.
When you have enough shells, you can either use a coffee grinder to turn them into powder or just roll them with a rolling pin inside a freezer bag.
Eggshells can be incorporated into the soil as you pot your plant or on top of the soil where a plant already exists.
Never dig too deeply into the dirt when working with an existing plant to protect the roots.
Banana Peels
Bananas are not only a delicious snack for fit people, but they may also provide your houseplants a much-needed nutritional boost. A healthy dose of potassium is added to the soil by bananas, which is particularly beneficial when producing roses.
Bananas can be used in a variety of ways to improve soil. The first approach entails making a kind of banana peel “tea.” Old banana peels placed in a jar with water for a few days will impart nutrients to the water. You can then use this infused water to water your plants.
Banana peels can be pureed in water and used immediately, which is a similar technique to the one previously discussed.
Banana peels can also be chopped into little bits and incorporated into the soil surface, but this is more frequently done outside.
Used Coffee Grounds In Houseplants
An great nitrogen boost from used coffee grounds helps your indoor plant establish strong foliage. It is especially beneficial for acid-loving plants including roses, fruit-bearing trees, begonias, and African violas.
Utilizing coffee grinds as a top dressing is the first way to use them as fertilizer. It is advised to let your coffee grounds dry completely before sprinkling them on top of the soil in a thin layer. By doing this, mold growth will be reduced.
Similar to how banana peels are used, coffee grounds may also be turned into a liquid fertilizer by soaking them in a jar of water for approximately a week. You will receive water laced with nitrogen as a result, which you may use to feed your plants.
Green Tea
Another excellent choice for fertilizing acid-loving plants like the ones indicated above is using green tea bags or old green tea leaves.
Tannic acid, which is present in green tea leaves, aids in bringing down the pH of the soil. They also have high nutritional concentrations and increase soil oxygenation, which promotes the health of the roots.
Your plants can be given a brew of one green tea bag per two gallons of water around every four weeks to aid in their growth and health. Before delivering the water to your plants, make sure to let it cool first. Additionally, used green tea leaves can be incorporated into the soil’s top layer or composted.
Molasses
Blackstrap molasses has been grandfathered into the commercial organic fertilizer sector and is a tried-and-true miracle worker for feeding plants with homemade fertilizer.
Everyone is aware that molasses is less expensive than the name-brand organic fertilizers. Why not create your own fertilizer in your own home?
Plants can get a lot of carbon, potassium, calcium, manganese, potash, copper, magnesium, iron, and other vital minerals from molasses. Additionally, molasses serves as a food supply for the helpful bacteria that inhabit the soil.
Molasses is most frequently found in nutrient-rich compost teas where it gives the microbes that are brewing in the tea a sweet boost. This encourages quick growth and a diversified ecology that will nourish your soil.
To make a more potent soil amendment, molasses can also be combined with other organic fertilizers like epsom salts and alfalfa meal. Simply combine four gallons of water with one tablespoon of molasses, one cup of epsom salt, and one cup of alfalfa meal, and use this solution to irrigate your plants.
Epsom Salts
For plants that may lack sulfur or magnesium, epsom salts can be used as a specialized fertilizer. It’s crucial to use Epsom salts sparingly. It’s unlikely that magnesium or sulfur will be inadequate if you’re adding any other composts or natural fertilizers, therefore Epsom salts might not be required.
One of the necessary components for the molecule of chlorophyll is magnesium. This indicates that magnesium is the source of a plant’s vibrant, healthy green hue. Magnesium deficiency causes the green to deteriorate and the edges and spaces between the leaf veins to turn yellow. This typically first appears in the oldest leaves closest to the base of the plant.
Epsom salts can be a useful tool for rebuilding chlorophyll and restoring the healthy green color of your plant leaves if a magnesium shortage has been identified. Some herbs, roses, peppers, and tomatoes are among the plants more susceptible to magnesium deficiency.
Wood Ash
Your potting soil can easily and safely be raised in pH, or the amount of alkalinity, by adding ashes from burned wood.
Additionally, the potassium, calcium, and phosphorus in wood ashes are healthy doses that are good for a variety of plants.
Adding wood ash to your soil is not a one-size-fits-all approach, just like using epsom salts.
It should only be applied when necessary because, if the alkalinity is already high enough, it might injure the plants.
You should conduct a soil pH test to make sure the soil is below a pH of 6.5 to see whether adding wood ash to your potting soil will be beneficial. Wood ash may be detrimental to the plants if the pH level is higher than 6.5.
Simply sprinkle the ashes on top of the soil as a top dressing and gently rake it into the soil to mix if you want to increase the alkalinity of your soil.
To prevent uprooting the roots, take care not to dig too far. Water is added right after.
Gelatin Powder
Absolutely necessary for good plant growth is nitrogen. Gelatin powder is a simple way to get a little extra nitrogen, which can help your plant develop robust, healthy foliage.
This is especially useful for plants with huge, beautiful leaves, like elephant ears and Monstera plants.
One 7g package of gelatin should be dissolved in one quart of water to receive the correct dosage.
The powder is typically dissolved in one cup of hot water first, then three cups of cold water. About once a month, pour this mixture directly onto the ground.
Used Cooking Water
Many of the crucial elements that plants need are released into the water when foods like pasta, vegetables, or eggs are boiled. This comprises vitamins and minerals including calcium, nitrogen, and phosphorus.
There are many advantages to watering your plants with boiling water. It not only provides free nutrients that would otherwise be flushed down the toilet, but it also encourages the storage of nutrients in the soil and increases the soil’s capacity to hold onto water.
This is advantageous for plants that enjoy damp environments, such as ferns or umbrella plants.
Corn Gluten Meal
The byproduct of processing corn through wet milling is corn gluten meal. It is most frequently used as an organic pre-emergent herbicide and includes 10% nitrogen.
This means that while maize gluten meal won’t hurt plants that are already established, it is detrimental to the germination of seeds.
The slight nitrogen boost will really be helpful, especially for plants with a lot of foliage.
Apply a thin top-dressing of corn gluten meal to the soil’s surface and gently scratch it in to help it ingest.
Always take care to avoid disturbing the roots. Once the seedlings are good and sturdy, around two weeks following germination, this can be started. Corn gluten meal should still be used sparingly, though.
Banana Peels
Consider using banana peels to produce plant fertilizer instead of composting them. Nkhensani advises placing two or three banana peels together with water in a mason jar. I’ll throw the peels out and utilize the banana peel water on my plants after a week of keeping it sealed.
Alternatively, Nkhensani advises drying the peels before grinding and incorporating them directly into the soil. She explains, “I’ll do this most of the time when repotting a fresh plant that doesn’t seem very happy. Just keep in mind that, if you choose this path, the drying-out stage is essential for avoiding bugs.
Eggshells
By converting eggshells into a DIY fertilizer, you may give them a second chance “12 eggshells should be crushed and boiled in water. Nkhensani advises placing the water mixture into a bottle that carries around one liter of water and letting it sit for three to four days. “Water your plants after straining.
Make compost tea if you really want to take your DIY plant fertilizer to the next level. It makes use of food waste such as eggshells, banana peels, coffee grounds, and others.
Freshly-Cut Grass
Did you know that recently cut grass is bursting at the seams with nutrients that plants adore?” According to Nkhensani, if you have recently cut grass clippings, you can put the clippings in a bucket with water. “To allow the nutrients to flow into the water, let it soak for three to four days before watering your plants.
What common objects are useful for fertilizing plants?
Organic gardening is as popular as ever, and the techniques we use have a significant impact on both the planet’s and our health.
You can use a variety of all-natural garden fertilizers directly in your garden or with potting soil. Some of these fertilizers are simple enough to make or gather at home from your pantry or backyard. Here are our top 8 go-to homemade fertilizers for a range of purposes.
Grass Clippings
Make sure to gather your grass clippings from an organic lawn so you may use them in your gardens. Grass clippings, which range in thickness from half an inch to an inch, make excellent weed-blocking mulch because they are high in nitrogen, a nutrient that is crucial for most plants.
Weeds
Many of the weeds you’ll find in your gardens are highly high in nitrogen and will make excellent fertilizer, just like grass clippings. The issue is that once the weeds have been picked, you won’t want to put them back in the garden since any seeds will germinate and grow into more weeds. The answer? brew a marijuana tea. To do this, place the weeds you’ve removed into a five-gallon bucket and fill it no more than 1/4 full. Let the weeds soak for a week or two, and then fill the bucket with water to the top. Pour this nutrient-rich weed tea over your gardens once the water has turned a lovely shade of brown (like tea).
Kitchen Scraps
Making your own compost will enable you to put kitchen and garden trash to use. Compost releases nutrients slowly, which means a well-composted garden can survive a year or two without requiring reapplication of fertilizer. Additionally, compost aids in soil moisture retention, which is necessary for vegetable gardens to flourish throughout the hot, dry summers.
Manure
Various animals, including cows, horses, chickens, and even bats, produce manure. Although all types of manure are rich in nitrogen and other nutrients, you must utilize them with caution. Too much raw manure might burn your plants because it is quite acidic and may contain more nutrients than what your plants truly require. Utilizing composted manure is recommended. It is less acidic and nutrient-dense, so you can use more of it to increase the soil’s ability to retain water without endangering your plants. It won’t take long before manure transforms into a wonderful, odorless soil amendment.
Tree Leaves
Collect the fall leaves for your gardens rather than bagging them and tossing them out on the curb. In addition to attracting earthworms, retaining moisture, and being rich in trace minerals, leaves can help lighten up heavy soils. Use leaves as mulch to nurture your plants and keep weeds at bay, or till them into the soil (or add crushed leaves to potting soil).
Coffee Grounds
There are many uses for coffee grounds, but one of the better ones is as fertilizer for gardens. Many plants, including tomatoes, rhododendrons, roses, and blueberries, flourish well in acidic soil. Recycle your coffee grinds to help your soil become more acidic. There are two ways to do this: top dress by scattering the used coffee grounds over the soil’s surface, or create “coffee to pour on your gardens.” Make garden coffee by soaking up to six cups of discarded coffee grounds for up to a week, then use the coffee to water your plants that require acid.
Eggshells
If you’ve ever used lime in your garden, you are aware of its many advantages. It mostly aids in reducing the acidity of the soil for plants who dislike acid as well as giving plants a lot of calcium, an important nutrient. Although you can purchase lime, an all-natural fertilizer, at the garden center, there is a less expensive approach to achieve the same results. To utilize eggshells in your garden, simply wash them out of your kitchen, save them, and smash them. It turns out that lime, often known as calcium carbonate, makes up 93 percent of eggshells. Check out these other uses for eggshells here!
Banana Peels
Bananas are consumed for their potassium content, and roses also benefit from it. Peels can be easily composted by burying them in a hole next to a rose bush. Bury the peels in the top few inches of soil as the rose grows. Both of these methods will supply the plant with vital potassium for healthy growth. Here is information on trench composting.
Any one of these DIY fertilizers can help your gardens thrive, no matter what you’re growing!
