Mulching, oh now I know the right term to use.
I also learned about it from hive gardener here who posted that they don't remove weeds in their plants during summer or hot season so it could help retain the water in the ground. But they remove it when it is rainy season as weeds will grow fast together with their plants. I think it is also a way of mulching? Did I understood it right?
Putting those weeds being uprooted near in the plants could help retain moisture. Thanks for this information.
