If you'd like to give your plants a real boost without spending too much, you're going to love this idea: liquid manure made with lentils. It's a homemade, eco-friendly, and surprisingly effective remedy. which takes advantage of what we often throw down the sink to turn it into food for the garden.
It suits her wonderfully pots, vegetable garden and planters because it provides minerals, amino acids and compounds that promote growth. In addition to invigorating leaves and roots, it helps to bring about flowering earlier. and with greater strength, and can help keep certain pests at bay thanks to stronger plants.
What is liquid lentil fertilizer and why does it work?
When we talk about "lentil water" we are referring to two simple preparations: the liquid resulting from cooking lentils and a blended mixture of lentils with water that is diluted for irrigation. Both options concentrate nutrients and organic compounds. which plants readily absorb, especially if applied regularly and at the right time. You can see more about the two simple preparations and its nuances.
Lentils belong to the legume family, whose scientific name for this species is lens culinaris. This plant group is notable for its relationship with nitrogen-fixing bacteria in the roots, a valuable agronomic trait that explains the nutritional richness associated with legumes. Although in homemade compost we use the grain and its water, not the root, that nutritional heritage remains. See how plants utilize nitrogen in nitrogen-fixing bacteria.
The key point is that the water resulting from treating lentils (cooking or blending and dilution) contains minerals and substances that plants absorb through the substrate or, to a lesser extent, through foliar route. This stimulates the development of new tissueNatural defenses are strengthened and a very favorable growth environment is created.
A little bit of botany and history of lentils
Lentils originated in the Middle East and have been with humanity for millennia. It is estimated that they were already part of the diet in times as ancient as the Egyptian era., where its consumption has been documented since ancient times.
Over the centuries, cultures and cuisines crossed. For the Romans, its consumption became associated with simplicity and times of scarcity.But their nutritional value was never in doubt. Today, thanks to their contribution of plant-based protein and micronutrients, they remain a pantry staple.
It is no coincidence that such a humble seed can transform the appearance of a flowerpot. Its composition is rich in elements that also benefit plantsThat's why the liquid we get from cooking or blending them becomes a kind of ready-to-use "nutrient powerhouse"; learn more about all about fertilizers and its use.
Nutrients and compounds that plants use
Lentils are notable for their protein content, but the real trick to homemade fertilizer lies in the micronutrients. We find iron, phosphorus, and potassium in water., three elements that plants need for balanced growth; in particular phosphorous and potassium They are key to flowering and resistance.
Iron is key for chlorophyll synthesis and leaf coloration; when it is scarce, chlorosis and yellowing appear. Phosphorus promotes rooting and flower formationTherefore, it is especially interesting if you are looking for more flower buds and earlier flowering.
Potassium is involved in water regulation and resistance to stress factors. A good supply of potassium results in stronger and more tolerant plants. to changes in temperature or short periods of drought, which in practice helps them to get sick less often; know the Advantages of liquid fertilizers in this situations.
In addition, lentils contain calcium, magnesium, and zinc, among other nutrients. Calcium contributes to tissue strengthMagnesium is the heart of chlorophyll, and zinc is involved in essential enzymatic processes. This "cocktail" of micronutrients, added to amino acids present in the cooking water, is what makes the difference.
Benefits in the garden, vegetable patch and flower pots
Regular use of lentil water results in greener and more vibrant leaves. The growth of new outbreaks is accelerating. thanks to the availability of nutrients and a more "living" substrate after each nutrient watering.
Those who apply it consistently observe that the plants bloom earlier and more intensely, especially ornamental plants and many vegetables. By improving the overall nutritional status, flowering becomes more abundant. and sustained, which also benefits fruiting in fruit-bearing species; that's why it's useful as a complement to achieve a more abundant flowering.
Another advantage is the support against pests and diseases. Well-fed plants tend to be more resilient Insect and pathogen attacks, and balanced nutrition, help speed up recovery if there are any setbacks; here you can see how fertilization influences against pests and diseases.
As if that weren't enough, it's a homemade, economical, and zero-waste fertilizer: you take advantage of a resource that would otherwise end up down the drain. Ideal for urban gardening, indoor and outdoor gardeningand for those seeking sustainable and simple solutions.
How to prepare it at home: two very easy methods
Method 1: Lentil cooking water
This method is as simple as saving the water after cooking your lentils. Cook the lentils as you normally would and reserve the liquid. resulting from the cooking, allowing it to cool completely before using it on the plants.
The cooking liquid concentrates vitamins, minerals, and amino acids that are released from the grain during boiling. Once it's cool, use it to water once a week in pots, planters, or flowerbeds. If the mixture is too thick, you can dilute it with some water to make watering easier.
For more convenient use, you can strain the water in case there are any solid remains. The goal is to obtain a clear, fluid liquid. that it does not clog the watering can or sprayer if you make gentle foliar applications.
Method 2: Lentil blending and dilution
This second method allows you to prepare a more concentrated fertilizer from raw lentils and water. You will need 2 liters of water, 250 grams of lentils, a spray bottle, and a blender., nothing else.
The preparation is very straightforward: mix 1 liter of water with the lentils in the blender and blend until you get a semi-thick liquid. Once the texture is homogeneous, you can strain it if you prefer. to remove pulp or coarse remains.
Next, add the remaining liter of water to adjust the density and obtain 2 liters of usable solution. This dilution makes watering easier and prevents over-watering. in the substrate. That amount will be enough for several medium-sized pots.
The liquefied solution can be used primarily for irrigation, and occasionally as a foliar spray in lighter dilutions. If you use it in a spray bottle, make sure the mixture is well filtered. and apply preferably at sunset to avoid sunburn.
Recommended application, dosage and frequency
The general guideline is simple: use lentil water as a regular nutritional supplement, not as a substitute for regular watering. One application per week is usually sufficient to notice improvements in vigor, sprouting and flowering without saturating the substrate.
In small pots, one or two glasses per plant are more than enough; in large planters, increase the amount proportionally. The important thing is to thoroughly wet the substrate without overwatering it.so that nutrients reach the root zone.
If you are going to spray, do it once or twice a month with the mixture very clear and filtered. Foliar application can complement irrigationHowever, the main use of nutrients occurs through the root.
During heat waves or periods of intense growth, you can maintain the weekly frequency; if the plants are dormant or the weather cools down, reduce the frequency. Observe your plants and adjust the guidelines according to their response.which is the best guide for fine-tuning dosage and frequency.
Which plants is it suitable for?
This homemade fertilizer works wonderfully on indoor and outdoor plants, as well as vegetables and flowers. It is versatile and compatible with most ornamental species. in pots and with urban garden crops that appreciate a nutritional boost.
In flowering ornamentals, its contribution of phosphorus and potassium results in better flower buds. In leafy vegetables, you'll see more greenery and sustained growth.In potted woody species, it contributes to maintenance and general vigor.
As with any fertilizer, it is advisable to avoid excesses in very young or recently transplanted plants. Give them a few days to settle before introducing the fertilizer.and use mild dilutions at first to see how they respond.
Practical tips to get the most out of it
It is best to apply the lentil water during times of lower sunlight. Early in the morning or at sunset It is ideal for minimizing rapid evaporation and making better use of nutrient irrigation.
If the cooking water is too thick, add a little tap water to thin it out. A fluid texture penetrates the substrate better. and distributes nutrients more evenly.
Before using atomizers, filter the liquid well to remove any particles. This prevents blockages and ensures a fine spray.Useful for lightly wetting the upper and lower surfaces of the leaves if you make very dilute foliar applications.
Alternate lentil water with your normal waterings and, if you already use other fertilizers, reduce them a little so as not to overdo it. The key lies in nutritional balancewhich is what truly keeps plants strong and beautiful; if you're unsure between options, find out more about organic and mineral.
Signs of good response and minor adjustments
When the plants are happy with the treatment, you'll notice it in just a few waterings. Firmer leaves, a deep green color, and new shoots They are the first indication that the micronutrient intake is having an effect.
If you notice that the substrate takes too long to dry or there is a bad smell, space out the applications. One nutritious watering per week is a flexible guidelineAdjust according to pot size, ventilation, and ambient temperature.
During flowering season, maintain the pattern and observe the appearance of buds. The extra phosphorus helps them arrive sooner and stronger.In plants focused on vegetative growth, the greater the greenness, the signal to follow.
