Buying a house and we love it! One problem there is vermiculite in the attic used for insulation. It is now said that it has a 50% chance of having asbestos. How do i remove it safely?
Stem cuttings are rooted in water or a moist potting medium such as sand, peat moss, or vermiculite.
Clay minerals have large surface areas with weak electrostatic charge, so tend to be able to absorb a lot of nutrients (and water, actually), and thus tend to be good as part of a potting soil mixture. The vermiculite will not decay into something else, releasing its structurally-bond components, but like all clays, it is a good source for storage and capture of nutrients that can be later taken by plants. Acts like a kitchen cupboard in a sense. You have to replenish the cupboard once in a while or it will get empty, is all. If you add liquid fertilizer to a soil containing vermiculite, some of it will absorb onto the surfaces and be available for later uptake, once the concentration of free nutrient constituents starts to fall.
