Please help! I've had a shamrock plant for over 25 years. Started as a little 3" potted plant. It was quite spindly looking so repotted it (it's been 10 years!) put it on my deck and it's gone absolutely crazy with growth. I live in North Central Washington state and will need to bring it back into the house soon. My concern is, it probably has all kinds of little creepy crawly friends living on it. How do I get rid of these friends before bringing it back inside? I really don't want to use chemicals and am hoping for some natural "bug ridding" solution. Many thanks!i
