Creating your own organic potting mix is a great way to ensure that your plants are getting the best possible growing medium. Here are the steps to create your own organic potting mix:
Start with a base of peat moss, coconut coir, or a mixture of both. Peat moss is a natural, lightweight material that is great for retaining moisture, while coconut coir is more sustainable and has a similar texture to peat moss. Mix the two in equal parts for a balanced potting mix.
Add organic matter to the potting mix to provide nutrients for your plants. Good options include compost, worm castings, and well-rotted manure. Mix in about 25% organic matter to the base material. Read this article for more information on how to make your own worm castings.
Add a mineral component to the potting mix for added nutrition. Good options include perlite, vermiculite, or sand. These materials will help to improve drainage and aeration of the mix.
Finally, add a small amount of organic fertilizer to the mix. This will provide your plants with a slow-release source of nutrients. You can use a pre-mixed organic fertilizer or make your own by combining bone meal, blood meal, and kelp meal in equal parts.
Mix all the ingredients together thoroughly, and your organic potting mix is ready to use! Remember to water your plants regularly, as organic potting mix tends to dry out more quickly than regular potting soil.
