Weed Growing Farm

Just a few months after I cut down most small trees, the weeds grew so high and covered my planted fruit trees in this part of the farm. 
It shows how sunlight can easily blow out the vegetation in the tropical climate. It also shows that the difficulty to maintain a farm without using pesticide.
But everything has good side, I make use of this vegetation as fertilizer to the fruit trees. The only thing is, I have to pull the tender plants regularly, not more than two months. But I am sure that the fruits produced will not be polluted with deadly chemicals although I may have to share with many insects and birds.
