One thing is for sure, if you are a gardener who loves to grow tomatoes, saving egg shells should be a high priority. Not only can they help protect tomatoes from disease, they can also energize and fertilize plants. And if that wasn’t enough, they can also help protect them from pests as well.

But as incredible as using egg shells can be for your tomatoes – and they really can be – there are a lot of misconceptions about their true effectiveness. And even more, how they should actually be used to help tomatoes. And that is exactly what today’s article will cover in depth!

Egg shells can be extremely helpful to your tomato plants – and your harvest totals!

The simple truth is that if you use egg shells in just the right way, you will grow better tomatoes. Egg shells contain three major nutrients that tomato plants need desperately – calcium, magnesium and phosphorous. With enough of each, your plants will thrive. And without – trouble looms!

However, and this is a BIG however, simply throwing a few broken egg shells into a planting hole or spreading them around the top of your tomato plants will not help your plants. At least not this year’s plants anyway.

So with that in mind, here is a look at the truth about how egg shells can power tomato plants – and how to use them just right to grow your best crop of tomatoes ever this year!

The Truth About Egg Shells And Tomato Plants

Before we get into how to use egg shells correctly, it’s important to know what the nutrients in them can do for tomato plants. More to the point, the calcium, magnesium and phosphorous that egg shells have that tomatoes need.

Calcium is responsible for strong cell development in stems and branches.

Calcium is by far the biggest player when it comes to a tomato plant’s health and production. It is the nutrient responsible for creating thick, healthy cell walls in the stems and branches of a tomato plant. When there is plenty of calcium in the soil, tomato plants develop to their maximum potential.

Even more, calcium also plays a massive role in the health of a tomato plant’s fruit. Without enough calcium, tomato plants can’t properly develop their blossoms into healthy fruit. Instead, the blossom end of the fruit rots as it develops, and the fruit is ruined.

The phenomenon is known as blossom end rot and it can all but ruin yields. But as long as there is plenty of calcium in the soil, it never becomes an issue. The great news – an egg shell consists of nearly 95% calcium!

Magnesium & Phosphorous – The Truth About Egg Shells And Tomato Plants

Not to be lost in the nutrient value of egg shells are the magnesium and phosphorous they can provide to tomato plants as well. Magnesium is vital in powering the photosynthesis process in tomato plants. Without it, the plant can’t convert the sun’s energy into the power it needs to grow.

Quite often, when a tomato plant’s leaves curl or turn yellow, it is not a lack of water but a lack of magnesium that is the cause. Without enough magnesium, tomato plants will grow weak and it can severely impact their ability to form fruit.

Phosphorous meanwhile is responsible for powering blooms. Without enough, tomato plants simply can’t produce a mass of flowers. And without prolific flowering, a big harvest is out of the question. The great news again – egg shells contain a fair amount of both magnesium and phosphorous as well.

But with all of that said – although egg shells contain an amazing amount of great nutrients for tomato plants, getting those nutrients out of the shells and into the soil and your tomato plants quickly requires a bit of extra effort. Luckily – it’s extremely simple to do!

How To Use Egg Shells To Power Plants – The Truth About Egg Shells And Tomato Plants

One of the best ways to use the power of egg shells is in the planting holes of your tomato plants. But how you use those shells in the hole is extremely important to how much they can help!

The biggest mistake gardeners make with egg shells when trying to help their tomato plants is to not first grind the shells down into a fine powder. Egg shells take a long time to break down. Even ones that are crushed into smaller pieces.

The key to using egg shells with tomato plants is to pulverize the shells into a powder. This way, it can release its nutrients far more rapidly to the plants and soil.

The answer? Grind those shells into a fine powder, and you unlock their potential almost immediately!
