Are Eggshells Good for Cactus

Are you struggling to keep your cactus plants healthy and thriving? Do you constantly battle blossom end rot, root damage during transplanting, or nutrient deficiencies? If so, you’re not alone.

Many cactus plant owners face these challenges, but the solution may be right in your kitchen. That’s right, eggshells you may have been throwing away can be a valuable resource for cactus plant care.

This blog post will explore why eggshells are good for cactus. By the end of this post, you’ll have a new appreciation for this common household item and know how to use it effectively in your cactus plant care routine.

So, let’s get started!

Benefits of Using Egg Shells for Cacti

1. They Improve Drainage

Eggshells are good for cactus, as they are full of necessary minerals for the soil, making them an excellent option to improve soil drainage. When added in small pieces to a pot’s soil mix, eggshells provide a better water flow since they help prevent water from accumulating at the root level.

However, it is important to note that the eggshells must be completely dried before being added to the soil. This ensures that any bacteria or smell associated with eggs won’t be present while growing plants.

2. They Add Calcium

Eggshells are good for cactus as they are a good source of calcium.

Calcium is an essential nutrient for plants, and a lack of it can cause various problems, such as stunted growth and leaf yellowing. Eggshells are composed of calcium carbonate, a form of calcium readily available for plant uptake.

As the eggshells break down, they release calcium and other minerals into the soil, which the cactus can absorb through its roots.

However, it’s important not to overdo it with the eggshells, as too much calcium can lead to other nutrient imbalances.

It’s best to use eggshells in moderation and supplement them with a balanced fertilizer that provides all the essential nutrients your cactus needs.

3. They Discourage Pests

Eggshells for cacti can be beneficial in several ways, including helping to deter pests.

Eggshells can discourage pests by creating a physical barrier that makes it more difficult for pests to access the soil around the cactus.

Also, eggshells’ sharp edges can help repel certain pests with their sharp edges. For example, slugs and snails don’t like to crawl over sharp surfaces, so crushed eggshells can help keep them away from your cacti.

4. They Reduce Soil Acidity

Eggshells are primarily composed of calcium carbonate, which is an alkaline substance. When eggshells are added to soil, they can help to raise the pH level, making the soil less acidic.

This can be especially beneficial for cacti, as many species prefer soil with a slightly alkaline pH.

In addition to helping to balance soil acidity, the calcium in eggshells can also help to improve soil structure and provide important nutrients for plant growth.

5. They Act as a Slow-Release Fertilizer

Eggshells are good for cactus as they act as a slow-release fertilizer.

A slow-release fertilizer is a type of fertilizer that releases nutrients over an extended period, typically several weeks or even months. Slow-release fertilizers are designed to release nutrients gradually, which helps avoid over-fertilizing plants, which can damage the plant’s roots and leaves.

Slow-release fertilizers can be particularly beneficial for cactus plants since they are adapted to survive in harsh, nutrient-poor environments.

Slow-release fertilizers can help supplement the limited nutrients available in their soil and provide a steady supply over an extended period.

6. They Help Prevent Blossom End Rot

Blossom end rot is a common problem in cactus plants caused by a calcium deficiency.

Since eggshells are a rich source of calcium, they can help prevent blossom end rot in cactus plants. By crushing up eggshells and adding them to the soil or mixing them into a slow-release fertilizer, the calcium in the eggshells can slowly release into the soil, where the plant roots can absorb it.

This will help ensure the cactus plant has sufficient calcium to prevent blossom end rot and promote healthy growth.

Since eggshells release nutrients slowly, they do not cause over-fertilization, which can contribute to blossom end rot in cactus plants.

7. They Help With Transplant Shock

Eggshells for cacti can also make transplanting easier.

When transplanting a cactus plant, it can experience transplant shock, a common problem when a plant is disturbed and its roots are damaged.

Transplant shock can cause stunted growth, wilting, and even death in severe cases. Eggshells can help alleviate transplant shock and make the process smoother for the cactus plant.

The calcium in eggshells can help stimulate root growth in cactus plants, which is especially important during transplanting. When the roots are damaged, calcium can help repair the damage and promote new root growth. Also, eggshells can act as a barrier that protects the roots from damage during transplanting.

Things to Keep In Mind When Using Eggshells

Here are a few things to keep in mind when using eggshells for cacti;

  • Ensure that the shells are ground and blended into a fine powder so they can be integrated into the soil and not affect your plant’s health.
  • The ratio between eggshells and soil should be equal to ensure proper absorption, which will help the cactus reach its full potential.
  • When applying the powdered shells to your cactus, be sure not to put too much around the edges where roots are growing; these parts require air circulation, and too much moisture could cause root rot.
  • Make sure you water moderately so that the eggshell fertilizer can have time to dissolve.

When done properly, using eggshells for cacti fertilization can benefit your plant and save you money purchasing specialty fertilizers.

Wrapping Up!

Using eggshells in cacti soil can be an excellent way to improve its structure and increase the plant’s health. Eggshells provide essential nutrients and help with drainage, root rot, water stress, aeration, pest control, and even transplant shock.

These benefits make them an ideal and free-soil amendment for cacti. Now that we’ve covered everything you need to know about using eggshells for your cactus, it’s time to try it!
