Over-watering is a common cause of Nostoc algae proliferation. Most garden and lawn plants only need 1 inch (2 in hot, dry weather) of water during weeks in which there has been no rain.
What causes Nostoc?
Nostoc typically appears after heavy rain. The cyanobacterium may exist in a black, crusty state during dry periods. But as soon as it rains, the Nostoc expands and grows its jelly-like covering. It is important to recognize that Nostoc does not kill turfgrass, and it will not damage your lawn.
How do you prevent Nostoc?
Some nurseries have had success with using heat to kill Nostoc, using hand-held flame-throwers or tractor-mounted propane heaters. Repeated treatment may be necessary to prevent re-establishment of Nostoc colonies. Soil solarization can also be effective.
How do you kill Nostoc on gravel?
Aerate the soil where it seems to be growing, eliminate the wet qualities of the soil around the area and get rid of the shade. As I have done my research, I have discovered that baking soda sprinkled over the nostoc algae will kill it.
How do I get rid of algae growing in my driveway?

Does Roundup cause Nostoc?
Chemicals. Algaecides such as sodium carbonate peroxyhydrate and copper sulfate products provide limited to no control of Nostoc. Herbicides such as glyphosate (e.g. Roundup) not only provide no control, but the release of phosphorus from dead plants can actually support Nostoc growth.
Are blooms of Nostoc harmful?
If the specialized bacteria are not present, microcystins can persist in the aquatic environment for months. BMAA can bioaccumulate in zooplankton and fish, so this nerve toxin can contribute to health risks long after the toxic bloom has died back.

Algae blooms can occur when a combination of suitable environmental conditions exist for abundant algal growth (e.g., increased nutrients, warmer temperature, abundant light, and stable wind conditions).
What are the different ways techniques to control algal blooms?
Common methods to prevent algal blooms include aeration, chemical/biological additives, or ultrasonic technology. Although there are plenty of treatment solutions on the market, they all have their cons. For example, algaecides offer quick results but damage the entire water ecosystem.
