I have several clusters of fireball type broms growing outside in hanging baskets and on trees in my yard. I would like to cut off a few broms to use in my pdf terrariums. What would be the best/safest way to clean/disenfect them so they can go into vivs. They have a host of insects in them,like spiders,pill bugs and possible bird droppings-i see birds perching on them frequently. Also i need to bring them in anyway because of possibility of frost is on the horizon. Thanks for any suggestions!
