Can reflected sunlight help grass grow in a shady spot?

Post by whiteangel » April 29th, 2014, 10:59 am

Hi,

I have a shady spot in my lawn. It only gets sunlight for about an hour every day so the Bermuda grass doesn't grow well and the patch remains bald. Could I use a reflector to deflect sunlight and light up the shady spot?

Will it help the grass grow, or does grass need direct sunlight?

I m not sure but I think direct sunlight is not necessary for the growth of lawn grasses. As grasses can make its food in the day light too (not direct sunlight is necessary). If it is getting enough light (not direct sunlight) then the causes of patches many be some another, Like excess water standing over there ( also bad drainage) or no watering there, nitrogen burn or its casual agent also may be a pathogen.

Lets what other suggest.

Well, there is no difference in direct sunlight vs. reflected sunlight from a mirror. In principle, it may be a nice idea but engineering wise it is a headache for a home gardener. The bad news is that the reflector will work for a short period of time. The reflector has to follow the direction of the Sun which keeps on changing.

Just across the shady spot, I get good light for at least 6 hours a day. So If I put a reflective surface over there it will give good light for at least a few hours. I was also thinking of something like a concave mirror. The kind they use to help drivers navigate on blind corners up in the hills. Because it will be concave, it might do a better job of spreading the light.

It's an experiment, it might work, it might not, let's see.
