I went to check on the progress of my farm after about 2 weeks the grasses were removed. I noticed there were just few changes and the grasses have started growing back.
The herbicides dealt with those grasses much more compared to the ones they used hand to remove them. The section they used hand grew rapidly while the herbicides section didn't. Most died flat.
I noticed some part of the farm just didn't do well. Stubborn grass, goat and chicken really dealt with them. They were very short and started bringing forth flowers.
However, one side looked larger and gallant because there was no much grasses preventing them from germinating. Also, my groundnut is doing very well.
