What about black spots?

Precious orchids dyed with black spots spoil the scenery, cut and stay, which is not the taste in my heart. On one occasion, Lan you introduced his experience and said that he could be cured with a touch of red-hot iron. I made it the same way, and the effect is really good. The burned part of the iron turns green and turns white, but keeping a complete leaf does not affect its appearance. If the black spot in the leaf tip, leaf edge, after burning, do not look carefully can not see, with black spots in the leaves, you can use a magnifying glass to focus burns in the sun. Use iron or magnifying glass to master the temperature, high temperature is easy to scorch or breakdown, affect beauty, low temperature, bacteria do not die. Only the best temperature can get the best effect. This square is suitable for retired Lanyou for leisure purposes, the number of fine goods is few, there is time to find disease spots very early, the burn area is small, and the effect is satisfactory.
