I have planted many fruit tree saplings on this monsoon season. There won't be any irrigation as of now in the farm for them. So planning to grow mexican sunflower cuttings nearby to each saplings. Typically around 2-3 feet away from the saplings and in opposite direction, so that mulching can be still done without much disturbance.
Still have to get more cuttings of mexican sunflower, I can see them growing on road sides, have to cut and take them. If they grow and provide shade, I am thinking saplings will survive the summer.
