The old saying about an ounce of prevention being worth more than a pound of cure is exactly true when it comes to lawn diseases and fungus in Buffalo Grass.
Preventing the onset of lawn diseases such as lawn fungus in Buffalo grass is really a very simple process which involves nothing more than following good lawn care practices which we should all be following with our lawns at all times.
These lawn care routines will not only give our lawns the greatest chances of being the beautiful lawn we all desire, but will doubly help prevent lawn diseases and lawn weeds from establishing.
The best place to begin, all these lawn care practices will greatly help to reduce any onset of lawn disease.
However, for specific lawn disease prevention, these are the most important points.
Do not over fertilise lawns… excessive nitrogen promotes fungal diseases such as Brown Patch. Apart from this, excessive fertiliser will be washed away into the environment, as well as creating excessive leaf growth in the lawn which may also cause scalping during lawn mowing.
If you have an outbreak of fungal disease in your Buffalo lawn, then completely stop all fertilising until the patches of affected turf have disappeared.
Yes, we did just cover fertiliser as a cause of lawn disease, but it is also a preventer of lawn disease.
Over-fertilising will indeed create an excess of nitrogen in the soil, which will promote disease.
But a regular year round fertilising regimen, using a quality fertiliser at manufacturers recommendations will greatly aid in creating a very healthy and strong lawn.
And a strong, healthy lawn will fight off lawn disease at the very time the disease is trying to establish itself. And at the end of the day, only a healthy lawn can fight off and win against lawn fungal attacks. Lawn fungicides are only ever a band-aid measure, and not the cure.
Water only in the morning. This is a golden rule of lawn care. Night time watering is the single largest contributor of most lawn fugal diseases and other lawn pest problems. This is especially true in the warmer months of the year when the water will sit on the leaf and inside the thatch layer of the turf, creating very moist and humid conditions. Conditions which are perfectly suited for the growth of fungal lawn diseases.
Regular lawn mowing will greatly aid in keeping the Buffalo lawn thatch under control, as well as reducing leaf length, and by doing so - will reduce the prime area of real estate which lawn diseases propagate in. Don't leave the lawn too long between cuts, keep it regularly mowed and you'll not only create a lovely looking lawn, you'll also be protecting your Buffalo lawn from disease.
Lawn soils will become compacted over time, and when they do, the soils can block oxygen getting to the roots of the lawn, as well as creating a water-logging effect, which will once again promote lawn disease while also bringing the lawn into poor health. In it's weakened state, the lawn will be much less able to fight off disease.
Lawn aeration can be done by a couple of different methods, and should be done anywhere between once a year, to once every 2-3 years. But the important thing is that it must be done, your lawn will love you for it!
Direct Sunlight and Shade
Another promoter of lawn diseases is lack of direct sunlight to the Buffalo lawn, which will also invite the growth of moss.
Keep the lawn in good condition by regularly pruning surrounding trees and shrubs to ensure enough direct sunlight is reaching the lawn each day. There's no need to go overboard with pruning, but every little bit of extra sunlight will go a long way to creating a strong and healthy disease free lawn, and without any fungus appearing in your buffalo grass.
