Algae & Lichens in Lawns

Algae

AlgaeDuring wet weather an area of exposed soil within a lawn may develop algae which looks like a green or blackish covering.   Algae on a lawn are a symptom of poor drainage, or compacted soil.

Hollow tine aeration is recommended to reduce the compaction.


Lichens

LichensLichens found on UK lawns are normally greenish-black or greyish leaf-like structures that grow horizontally in the turf.   Similar to algae, lichens are symptoms of poorly drained, compacted soil.

Hollow tine aeration is recommended to reduce the compaction.
