Author Message   Costaricafinca  My Garden Posted on Tuesday, October 16, 2007 - 09:55 am EST :    I am posting this question for a friend. They have received so much rain in an area near an actual 'rain forest' here in Costa Rica, that has resulted in a huge accumulation of moss and lichen on the hibiscus and other similar shrubs. Due to the amount of shrubs my friend has, he would like some info on the removal of the 'ugly matter'. Preferably something he could apply to the plants rather than scrape off. Thanks Costaricafinca - Guanacaste, Zone "?"   Kniphofia  My Favorite Photo My Garden Posted on Wednesday, October 17, 2007 - 08:17 am EST :    I don't know how anyone could describe mosses and lichens as 'ugly matter'! I would be happy to encourage them in my garden. They are usually a sign of very clean air - lichens are anyway. Perhaps your friend could grow to love them?

But the problem remains, that it look like causing major damage on the plants, here.

They basically help each other grow in a form of symbiosis. Lichen is not a threat to other plants but its presence indicates that the plants are stressed due to excessive moisture levels. Just as lichen "appeared" when the moisture levels increased, the opposite also holds true: less humid conditions will inhibit their growth. Consider watering the soil instead of watering the plants. Water when the soil feels almost dry to a depth of 3-4 inches. And do so only in the mornings. Last suggestion... allow for good air circulation between plants. There is a product called BIO-LICHEN OFF available from Sunnz International Ltd, P.O. Box 13-598, Onehunga, Auckland, New Zealand that is said to be a fast acting and effective concentrated product designed to remove all Lichens, Moss and Fungal growth from most surfaces. However, I am not sure if it can be used on plants as most people try to remove lichen from rocks instead so check http://www.sunnz.co.nz/ Luis_pr - Hurst, Texas, Zone "USDA 7b/8a"
