The calcium carbonate in eggshells helps to strengthen a plant's roots so it can grow faster and stronger. Simply crush clean, dry eggshells into a fine powder.
Eggplant, peppers, broccoli, cauliflower and leafy greens, to name a few. But don't go overboard. Since it takes a while for the shells to decompose, Uyterhoeven recommends applying eggshell fertilizer to your garden or indoor plants just twice a year—in the fall and spring.
One final note: Make sure your soils aren't already alkaline before you add anything to up the pH; and never ever use eggshells or other pH-raisers around acid-loving plants like azaleas and rhododendrons.
If you don't want to make the water mixture because that seems like too much work or you simply don't have the time, you could always collect your eggshells, clean them, and crush them directly onto the soil in your garden or into a fine powder to get similar results.
Eggshells are rich in calcium, and this makes them a common ingredient of commercial organic fertilizers. But there's no need to pay for the nutrients these products could bring to your soil. Simply crumble the empty eggshells roughly, then scatter them over your flower and vegetable beds.
Because it takes several months for eggshells to break down and be absorbed by a plant's roots, it is recommended that they be tilled into the soil in fall. More shells can be mixed into your soil in the spring.
Should You Wash Eggshells Before Composting? It is not a requirement to wash eggshells before composting them, but you definitely need to. First, cleaning them speeds up how fast they will break down inside the composting bin. Secondly, cleaning them is important so as not to attract animal pests.
Start saving your egg shells from breakfast. Halve them and make sure you rinse them out thoroughly. Using a small needle, make a small hole in the base of each egg shell for drainage. Using a teaspoon, add seed compost to the egg shell.
If you split your eggshells into small fragments, it can take roughly one year for them to break down into the soil. Thrown in almost whole, and you could be looking at several years before they decompose.
Slugs, snails, and cutworms can do severe damage to your garden. Protect your plants from these pests by spreading coarsely crushed eggshells around your garden. The jagged edges work much like Diatomaceous earth by cutting and then dehydrating these common garden pests.
The first thing you need to do is bake your eggshells to kill any potential bacteria including salmonella. Preheat your oven to 400°F and bake your eggshells on a baking sheet for 10 minutes. In addition to killing bacteria, this will also make the shells more brittle and easier to crush into small pieces.
In most cases, the grounds are too acidic to be used directly on soil, even for acid-loving plants like blueberries, azaleas and hollies. Coffee grounds inhibit the growth of some plants, including geranium, asparagus fern, Chinese mustard and Italian ryegrass.
Epsom salt can improve the blooms of flowering and green shrubs, especially evergreens, azaleas and rhododendrons. Work in one tablespoon of Ultra Epsom Salt per nine square feet of bush into the soil, over the root zone, which allows the shrubs to absorb the nutritional benefits.
You can water your plants with banana peel water fertilizer once a week. Many plants require watering once a week, so you can use compost tea during each hydration session. However, if your plants need a drink more often in the summer, stick to only using banana water once a week.
Eggshell Powder: an All-Natural Plant Fertilizer
You can simply add crushed eggshells in or on the soil as a natural way of providing your indoor plants with extra calcium. Another advantage is that the eggshells will also help to aerate the soil. Airy soil makes it easier for your plant's roots to grow.
Because eggshells are so versatile, you can use them as pest control as well as nutrition for your plants, be it for growing tomatoes or making compost.
Translucent areas of the shell are weaker than opaque areas and this difference is more marked at a week old than in a newly laid egg. Soaking the shell in water weakens it but also eliminates the difference between the two types of area, while oven‐drying strengthens the shell but also eliminates the difference.
Combine the two together, crush the eggshells by hand even more (which should be easier now that they're fully dry), and sprinkle the mixture across the soil bed. Repeat the process every several months or at the start of a fresh growing season. The important thing is to not overdo it.
The shells will decompose quickly and naturally, and when they do they'll add lots of calcium to your pile. It's a common misconception that you can't put eggshells in compost piles because the shell is too hard, but this is far from the truth.
How long does it take for an eggshell to decompose? Eggshells take more than 3 years to break down. In an eggshell decomposition study, the outer shell was found intact after a year underground. On the same, and after three years under the soil, there are no signs of decomposition.
Banana peels are a great ingredient for your compost or worm farm, adding lots of nutrients to the organic recycling process. Council is making purchasing your organic recycling system easier with our compost rebate program.
Epsom Salt for Plants
Aside from the anecdotal evidence about human benefits, Epsom salt does seem to help plants. Generations of gardeners have said it helps their plants grow bushier, produce more flowers and have better color. It's also said to help seeds germinate and repel slugs and other garden pests.
Coffee grounds are rich in nutrients, especially nitrogen. They also have some amount of other nutrients like potassium and phosphorous. Overall, this means that adding coffee grounds to your garden can work fairly well as a fertiliser. Coffee should be spread in a thin layer, rather than being clumped in one place.
Increase calcium levels: Due to their high calcium content, eggshells may improve your soil's calcium levels over time. Eggshells take some time to break down, so the smaller particle size, the faster you'll see results. Before using eggshells as a soil amendment, test your soil to see if you have a calcium deficiency.
