It is beneficial to use egg shells when growing your own vegetables like tomato, pepper and aubergine or plants such as roses, hydrangeas, spider plants, ferns and ivy. Another way to add this homemade fertiliser to your plants is through a calcium solution.
There are multiple plants that benefit from eggshells in your garden. Tomatoes, peppers, broccoli, spinach, lettuce, Swiss chard, flowers, strawberries and squash are some examples!
Eggshells take a lot longer to break down compared to many other compostable goods, and too many of them can increase the acidity of your compost. This shouldn't be a problem, unless you plan on using it to grow plants that prefer low soil pH.
All plants need calcium and can benefit from being planted in eggshell cups, but certain crops are more susceptible to blossom end rot including tomatoes, broccoli, Brussels sprouts, carrots, celery, squash, lettuce, peppers, melons, and eggplant.
Calcium is very good for tomatoes because it prevents blossom end rot. When starting from seed indoors will need 4 essential items: clean eggshells, egg carton, seed starting mix and tomato seeds (or any other plants of your choice – herbs, flowers, vegetable, etc).
While plants need nitrogen (remember the NPK on fertilizers), too much nitrogen will create lots of green leaves but few berries or fruits. This means potassium-rich banana peels are excellent for plants like tomatoes, peppers or flowers. Banana peels also contain calcium, which prevents blossom end rot in tomatoes.
You can put raw or cooked eggshells in compost, either washed or not, depending on how concerned you are about pests in your compost. You can put them in as is, but you will find that eggshells take a lot longer to break down in compost than other materials.
Depending on the size of your garden, compile enough of each component to contribute a moderate amount to each hungry plant. 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.
The biggest benefit after tomatoes is to cucumbers. Place the crushed shells of a dozen eggs right down in their planting holes to provide easy-to-reach calcium, and your cukes will be noticeably crisper — and that crispness will extend to any cukes that you put up into pickles.
Lay shells evenly on a sheet pan. Bake at 400°F for 10 minutes to dry the shells. Transfer shells to a food processor and pulse until finely crushed. Spread a thin layer of eggshell powder around the roots of vulnerable garden plants (repeat after heavy rain).
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.
Symptoms of calcium deficiency include stunted plant growth, leaf curling, dark leaf veins, weakened plants, and blossom-end rot in fruits. Fruit plants like tomatoes and peppers may develop dark, sunken areas in the fruit.
Plants like tomatoes, peppers and eggplants in particular will benefit from shell fertilizer, Savio said. The extra calcium will help prevent blossom-end rot. Broccoli, cauliflower, Swiss chard, spinach and amaranth are also calcium-packed and could use extra from eggshells.
Tea Can Work As A Natural Fertilizer
As the tea leaves and bag begin to break down and decompose, they release nutrients into the soil that helps plants retain water and thrive. That said, you should use tea only on your plants that like acidic soil.
"Plants like strawberries, blueberries, kale, and cabbage prefer slightly acidic soil and adding in eggshells can do more harm than good," says Jen McDonald, certified organic gardener and co-founder of Garden Girls, a garden design company based in Houston, Texas.
Avoid using coffee grounds on alkaline-loving trees, such as linden, ironwood, red chestnut and arborvitae. Coffee grounds used as mulch or compost inhibit plant growth on geranium, asparagus fern, Chinese mustard and Italian ryegrass. Definitely don't use coffee grounds with these plants.
Can I Just Sprinkle Epsom Salt on Plants? Never apply Epsom salt straight from the package. Always dilute the granules in water first, and either drench your plants' roots or spray it on the foliage. Don't spray on hot or sunny days, however, to avoid scorching the foliage.
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.
Composting worms can absolutely be fed with crushed shells from eggs. You should know that compost worms will eat just about anything that's organic (all except meat, seafood, poultry, dairy, oily, or spicy stuff).
Many gardeners use eggs in the garden to boost soil nutrients. Try putting eggshells in your compost. You can also plant eggshells or a whole egg in the hole before planting tomato plants.
Soil is alive and has its own ecosystem. If a banana peel is buried in the soil, microorganisms will work to break it down. But this can take away from the microorganisms providing the current nutrients in the soil to your plants.
Plant Legumes
Legumes like peas, beans, and clover form symbiotic relationships with nitrogen-fixing bacteria. Growing them enriches your soil for other crops. But these fertigation systems are the best if you want to boost your nitrogen doses more rapidly and easily.
However, the peels will break down so slowly that they likely won't provide adequate nutrients when your plants need them. Another downside to banana peels as fertilizer is that rotting organic matter can attract pests such as fruit flies, fungus gnats, and even cockroaches.
