Many unknown horticulture hacks spread the net , from coffee tree ground to banana peels to tea bags . supposedly , add together these household materials to your garden soil better plant growth . Many sources recommend sum eggshells to tomato plants for a fertilizer boost . Does science back this claim , or is it an urban soil myth ?
Eggshells are a rich beginning of Ca carbonate and trace sum of money of atomic number 12 , phosphorus , and other minerals .
They can be a helpful mineral plant food fortomato flora , but there are some key caveat to understand . allow ’s grasp into everything you need to experience aboutusing shell in your tomato beds .

The Short Answer
Eggshells can be agood source of calcium and constitutive matter for tomatoes , but they are unlikely to yield a major advance in grime calcium level . you’re able to add shell to your garden by drying , crushing , and incorporating them into the soil , or by composting them .
University research indicatesthat composting is the best way to make the minerals in eggshells usable to your plant life . Some anecdotal reports also evoke that dried eggshell can also deter slugs from feeding on young tomato transplants because the sharp edges of the shell desiccate the slug ’s body , but there is n’t much grounds or science to prove this call .
The Long Answer
Depending on how you add them to your garden , eggshell may leave some alimentary and cuss - deterrent benefits . The most notable reason you ’d want to add eggshells to tomato plants is as acalcium enhancement to reduce flower oddment rot .
Some grounds suggest thatcalcium inadequacy is linked to blossom end rotin tomatoes , while others find that alack of atomic number 20 does not make blossom end rot , and the result is far more complex . Both studies have the same basic reason heel for why a plant can not uptake calcium from the soil , so in both cases , they ’re ripe !
Typically , the issuance that impact tomatoes have less to do with the measure of calcium in the soil and more to do with environmental care , as both work state . Inconsistent lacrimation or all-embracing drought can develop blossom close rot , for representative .

Similarly , an excess of nutrients in the soil ( particularly magnesium , ammonium ion - based nitrogen , or potassium overloads ) can foreshorten the power of a plant to absorb calcium from the soil . industrial plant stresses due to diseases can also be the perpetrator , particularly any disease that girdle the plant ’s stem and cause a reduction in moisture transfer through the plant ’s tissue .
So , does atomic number 20 from eggshells help to keep peak end bunkum ? Yes and no . Eggshells are almost pure calcium carbonate , but they have to be fully break up down to be absorbed by the plants , so there ’s a time issue involved .
In accession , most garden soil is n’t miss in Ca , despite the symptoms of blossom terminal rot in a plant life . In most slip , something else is a central factor . The extra Ca generally wo n’t spite ( unless you tote up an nimiety to the soil ) , but generally , it ’s not going to fix the issue !

Benefits of Eggshells
These kitchen scrap can benefit your garden in a few ways , but there is n’t significant scientific grounds indorse any of them . Eggshells are mostly made of calcium carbonate quartz , which can contribute to soil wellness . This rich rootage of calcium helps plants build stronger cell walls . The shells also add together nitrogen , K , and chloride .
to boot , an egg ’s alkaline shell and membranemay help inbalancing soil pHin acidulent environments , but the issue will be very modest and localized .
The best above - ground welfare of eggshells is reputed to be pest control . Many gardeners apply them to protect unseasoned tomato plant plants from slug damage .

The jagged texture may deter and dehydrate slugs by damage their attender skin . However , if it rains , the shells become soggy and less effectual ; any preventive effect are very short - endure and often do not work .
Role of Soil Calcium
territory calciumis a crucial food for flora growth . Too much or too little calcium can cause major problems in harvest , just like excesses and want of specific vitamins can cause problem in humankind .
Soil atomic number 20 plays a role in :
In the soil , Ca interact close with magnesium . The proportion of these two minerals can touch how plants uptake other nutrient ( like potassium ) or how the soil clumps ( “ flocculates ” ) together . Without father into complex soil science , it answer to say that soil calcium is vital for a palmy garden and healthy Lycopersicon esculentum plants .

Calcium deficiency are most expeditiously address with agricultural lime ( calcium carbonate ) or dolomitic lime tree amendment . Eggshells canhelp improve dirt calcium levelsbut may take longer than traditional plant food .
How to Use Eggshells as Fertilizer
Throwing an eggshell into your tomato seam may seem like a immediate fix , but it ’s improbable to contribute anything to plant health . The headstone to any organic plant food isdecomposition .
The shells must be break down by microbial activeness to become available to your plants . Once disintegrate , they can also soften the territory against changes in sour .
1. Clean Residues (Optional)
Begin by collect eggshells from your kitchen and rinse them off before reposition . After each use , I like to rinse the shells and roll up them in an empty egg carton until I have at least two dozen .
you’re able to also collect them in akitchen compost binwithout washing them off . As long as youprovide the proper atomic number 7 - to - carbon ratio in your compost , the membrane and remnant of egg white should not be an issue .
2. Bake Them in an Oven (Optional)
Some sources suggest baking the shell to make them easier to crush . On an industrial graduated table , eggshell lime is put in an oven to make them more unannealed . Then , the residues are squeeze and pass through 2 millimeter sieve .
This is a plenty of work for a home gardener , but remember thatthe small you crush your eggshells , the good . If you have time to dehydrate in the oven , go for it !
3. Crush the Shells Into a Fine Powder
crush the eggshell makes it easy for microorganisms to break them down . This explain why giantwatermelonsor big tree limbs take incessantly to decompose , while supergrass clippings seem to compost in simple Clarence Shepard Day Jr. !
Some studies suggest that hand - crushing eggshells is insufficient to ensure decent dirt incorporation . Instead , blend them in a nutrient processor or blenderto make a fine pulverisation . If they have n’t fully dry out , they may clump together rather than work a powder . This stuff can still course the grime microbes but may be more difficult to spread .
A helpful tinge here : when you blend your eggshells , do not now afford the blender or food for thought processor afterwards . Blend them to a o.k. powder , then rent them sit for 10 - 15 minutes before opening the blender . This allows the airborne particulate in the blender to fall back down rather than come out in a swarm of okay dust in your kitchen !

4. Add to Compost or Add Directly to Soil
Adding your eggshells to acompost binis the best manner to make the calcium pronto useable . Some gardener put the crushed powder into the planting hole with their tomato plant , but the efficacy of this method depends on how many microbes are present in your soil .
If you have a productive , loamy garden bottom , your tomato industrial plant will quickly take in and utilize the powder . However , in poor soil without much life , pre - composting the plate will make them a far more good amendment .
These shells are also agreat addition to a worm bin . The slow - press release atomic number 20 improves thevermicompost ’s qualityand keep acidulous conditions in your louse bin . The worm can also apply pulverised eggshell as grit to assist their digestive procedure . admixture crushed eggshell in with worm sack out ( like shredded newspaper ) or scatter the powder in with your food bit .

Do Eggshells Deter Slugs?
The ragged border of dried eggshells supposedly deter slugs by cutting through their gentle bodies . This could be useful for spreading around young tomato plant plants attacked by these ugly pests .
However , in this experimentation with simoleons , the myth - busting squad atAllAboutSlugsput shell to the test and found that they do n’t do anything to kibosh slugs from eating your plants . You are better off usingan organic slug and escargot bait .
Final Thoughts
This garden hack may improve soil calcium around your tomato plant and prevent problems withblossom end rot . The headstone is tocrush and compost the shell firstto make the mineral uncommitted to your plants . All in all , there is no risk of adding eggshell to your love apple beds . They can not harm your tomatoes , but they may not render a obtrusive benefit .
