I’ve got this white powder on part of my lawn. What is that?

That’s a harmless fungal growth commonly referred to as “powdery mildew”.  It’s most prevalent during periods of high humidity and cool nights. It also tells you there is a high nitrogen content but it is completely harmless to your lawn. 

While a fungicide is available to treat severe cases, we at BAM! Green have never seen a case severe enough to warrant a fungicide treatment. 

What to do? Give it a few days — weather conditions usually change. The grass blades will continue to grow and the infected blades will simply get cut off by your lawn mower. Powdery mildew is also a common problem in many tree species.

All BAM! Green Lawn Care programs are guaranteed to improve the health and appearance of your lawn and eliminate broadleaf weeds. If your broadleaf weeds are not completely eliminated within 14 days of your second visit, we will gladly perform an additional weed control application at no extra cost. If you are not satisfied with the results we will cheerfully refund 110% of your remaining applications.


*This guarantee does not apply to weeds growing in other areas of your property outside of your lawn, or areas that are not being regularly mowed. This guarantee is not applicable to ground covers such as Creeping Charlie, Creeping Bellflower, or Yarrow. For advice on how to deal with these ground covers and non-broadleaf weeds, please contact our office and we would be happy to work with you do eliminate this problem. This guarantee is also void where proper cultural practices are not being followed or performed, or if the program is delayed by the customer.
