Growing plants in sterile medium
Long story short, following a lengthy (but successful) battle with cancer my mum has been advised that she can't garden for over 6 months, presumably to try to reduce the risk of infection whilst everything settles down. She is a very keen gardener and I know she will be missing being able to get in the garden! A
As it is her birthday coming up I had wondered whether it was possible to grow (relatively successfully) some houseplants in a sterile medium. I know (from a quick google) that they won't grow as well, but they can be transferred to proper soil at a later date. I thought it might be nice for her to be able to see some seeds germinate and at least feel like she is doing some gardened if that all makes sense?
I have assumed vermiculite is sterile, and was thinking about this (as it's easy to get hold of) but I don't know what would grow in the stuff. Whatever I get (if I can find anything) would either need to be a house plant, or at least something that can be started off in the warm before being transferred. What are my options? I was thinking (I have very limited knowledge) of maybe some kind of fruit tree like a lime or ideally something that flowers. I guess given the constraints and timescales something that at least looks interesting within 6 months would be a bonus. Of course it could be more than one plant! Would need to be grown from seed I think...
thank you for your help, apologies if this is the wrong section of the forum
