This "Weed" is very useful. I've been using Horsetail Tea as a fungicide for years. Believe it works by changing the ph of the plant surface making conditions unfavorable for fungal spores. Stops bean blight in its tracks. Claud

This plant is beautiful and works very well with tropical plants, but can be invasive. We grow it in an old galvanized washtub that's been half-buried, and that contains it just fine.
