If you are interested in starting a nursery, or are wondering how professional grower’s produce high quality plants, then this is the perfect post for you!
We are going to show you how to mix the perfect medium for rooting cuttings. This mix has been tried and tested in a commercial nursery and has been perfected by professional horticulturalists, so you can trust it’s a good one! For your own convenience you cal also download your own copy of our infographic detailing this information here.
To mix the perfect rooting medium, you will need:
As horticulturalists, we strongly advise that you use sustainably sourced peat moss and coir.
Once you have readied all of your equipment, place 2 cups of peat moss, 2 cups of coir and 1 cup of vermiculite into the bucket. This medium will therefore consist of 40% peat moss, 40% coir and 20% vermiculite. The peat moss and vermiculite absorb water whilst keeping the medium aerated, and the coir also improves water retention. However, these materials have very little to no mineral content. This is why we have included a slow release fertilizer in the mix. The amount you mix into your growing medium will depend on the amount of medium you need, so be sure to read the instructions before you add your fertilizer. In this case, we used roughly 2-3kg per m3.
Make sure your medium is thoroughly mixed with your peat moss, coir and fertilizer evenly incorporated. Fill up your cutting trays with the medium and soak the trays with a light mist before you start planting your cuttings.
