If you find the moss unsightly or fear it may weigh down a branch, you can gently scrape it off or apply a copper fungicide, following label instructions.Īlgae, usually considered an aquatic plant, can also grow on trees, walkways, roofs, fences and houses, thriving in moist or shady areas.
To discourage moss growth on a tree, prune branches in the center of the canopy to allow more light and air to circulate within it.
But if the growth is excessive, its waterlogged weight can threaten to damage branches. Growing in green or yellow mats or tufts, moss prefers low soil fertility, acidic pH levels and compacted soil. Moss is another non-parasitic organism that thrives in moist conditions and grows on trees, lawns or even bare soil in shady areas. If you’ve got lichens, you’ve got good air quality. The growth of lichens is actually a good sign because they will not survive in polluted areas. They typically present as pale green or gray (or sometimes orange) crusty or leafy masses on tree branches and trunks, rotting logs and wood fences. Lichens are symbiotic organisms of fungi, algae and possibly yeast that live off each other, not your tree.
But they aren’t parasitic they’re opportunistic, which is to say they like to grow on trees that are already ailing or growing in poor conditions. Those growths could be either lichens, moss or algae, and the good news is that none are cause for alarm.īecause they usually grow on stressed or declining trees, many people assume these organisms are responsible for making their trees sick. For instance, what are those green masses growing on your trees? Now that deciduous trees are bare, trunks and branches have taken center stage, and you might be noticing nuances and irregularities that evaded your attention over the summer.
