September Weeds in Buffalograss

I have discovered a way to spray pesky wild morning glory (field bindweed) in our buffalograss even if the temperatures are still hot.

Field Bindweed held in place with a clothespin over plastic ice
cream bucket lid.

I take old lids from ice cream buckets, put them down on the buffalograss next to the bases of the weeds, and drape the morning glory over the top of the lids. I pinch the stems and the edge of the bucket with a clothespin then spray Trimec over the weed. I let it dry and carefully remove the clothespin and bucket lid. So far, there appears to be no damage to the buffalograss when I do this, even when it is above 85 degrees. I am very careful to spray only the weeds. Try not to damage the stems of the weeds so the poison will absorb into the leafs and go down into the roots. In a few days, the morning glory begins to wilt and curl and eventually dies.
