Are eggshells good for orchids? This is a question that has been asked by many people, and the answer may surprise you. In this post, we will explore whether or not eggshells can be used as a potting medium for orchids and what the benefits might be. We will also take a look at some of the potential risks associated with using eggshells in this way. So, let’s get started!
Are Eggshells Good for Orchids?
It is a common misconception that orchids need highly acidic soils in order to thrive. In fact, most orchids prefer neutral to slightly alkaline soils with a pH between 6 and 7. This means that eggshells, which have a pH of around 7.5, could be a perfect potting medium for your orchid.
Eggshells are also rich in calcium carbonate, which is known to be beneficial for plants. Calcium is an essential nutrient for plant growth and helps to strengthen cell walls. It can also help to prevent blossom end rot in tomatoes and other fruit-bearing plants.
Another advantage of using eggshells as a potting medium is that they are very lightweight. This can be beneficial for orchids that are susceptible to stem rot, as the shells provide good drainage and aeration.
There are a few things to bear in mind if you decide to use eggshells as a potting medium for your orchid. Firstly, it is important to make sure that the shells are clean and free from bacteria. This can be achieved by boiling them for a few minutes. Secondly, the shells should be crushed into small pieces before being added to the potting mix. Finally, it is advisable to add a little extra lime to the mix to neutralize any acidity that may be present in the eggshells.
Overall, eggshells can be a great potting medium for orchids. They are rich in nutrients, lightweight, and provide good drainage and aeration. Just make sure that they are clean and free from bacteria before using them.
