It is quite important to have a good aeration in order to plant your vegetables, flowers or if your are starting a seed/sapling in potted plants whether they are indoor or outdoors. Vermiculite is hence an excellent additive to your soil mix to provide these necessary properties. Vermiculite is part of our ingredients in Bel-Patra soil. It is essentially an excavated mineral rock that is treated to use with garden plants/soil. It helps in aeration as we mentioned and also holds nutrients for the root to be able to reach.
