I discovered another useful trick to aid in the battle against the mighty mite.
Take a strip of Cellulous sponge material, about 1/2" wide by the necessary length to surroundthe plant's lower stem. Wrap it around the stem about 1" or 1-1/2" above the grade and secure with ties. Soak it down with your favorite solution be it pepper or Neem or whatever. Mites migrate, that is, they crawl from plant to plant. This band stops their migration as well as their escape and prevents others from coming onto the plant. This must be soaked wet every day while treating and weekly thereafter. It is just another helpful aid in the arsenal that we need to combat an infestation. I also make a circular donut out of the sponge and use a paper hole punch to make a hole in the center is about 1/4" dia. I then take a cutting and place it into the hole and then on to the cloning application I'm using be it rooter start plugs or Rockwool cubes or soil, or whatever. This keeps the donuts in place without ties, is already on the plant and a lot easier that the retrofit style, expands as the stem thickens and is simply done already. If I don't have a mite problem, I'll re-use it next clone. If I do get the mites, I am grateful that I don't need to do much to have this aid available. Simply pull it into place, soak the plants down and soak the donuts and good bye...
Oh and you can wash and re-use them too. They are cheap and can be found at a dollar store for a buck for three sponges that makes 9 of the donuts.
