Green plants are usually welcome in a lawn or garden, but algae or moss can become an unattractive eyesore that takes over your patchy lawn or backyard pond. While these strange plants aren’t the same, they’re both non-parasitic, primitive plants that are often discussed together. Using chemical control is usually a last resort, but we will give you tips on how to remove algae and moss from your pond or lawn with our professional grade algaecide and moss killer.

Moss is made up of fine branched, threadlike stems with very small leaves. It reproduces by windblown spores and makes it’s own food, meaning it does not steal any nutrients from your lawn. Moss will form a thick green mat on the soil surface. If you see lots of moss in your lawn, this is likely because the conditions are favorable for the moss, but not the grass. The moss takes up the space left by dead grass.
Algae are often fondly referred to as “pond scum” because of the green layer that may cover much of your pond or water feature. This is a primitive plant with no roots that can be broken up into three categories: microscopic, filamentous, and attached-erect. Microscopic algae is very common; this algae is made up of tiny free-floating algae that gives a pond that characteristic green color you’d rather go without. A little bit of this algae can actually improve the life within and water quality of your pond, so don’t be quick to get rid of a bit here and there.
Moss removal can be difficult. The most thorough method is cultural control, since moss favors any combination of abundant shade, acidic soil, poor drainage, compacted soil, and low soil fertility. You can try a number of things for moss control:
Algae removal can be difficult, but management can become an important part of your pond maintenance. Most pond algae are a pea soup green color and are more unsightly than harmful. Blue-green algae (cyanobacteria) can produce toxins that can be very dangerous to the health of animals or fish that come in contact with the water. Red algae can also be dangerous. Contact your local extension office for help on how to kill algae like this, but aquatic dyes can help keep the algae from growing. Algae control for ponds with common planktonic algae and filamentous algae, try some of these steps:
