The solution to increase the yields of Pine tress

Plant more trees in the field. The Disadvantage of planting pine trees, we need extra water for this tree. We also don’t have clean water in the ocean or lake and it also can affect the growth of the pine trees, planting pine trees also need a big space for the roots to grow and the space for the tree itself. The advantage of planting pine trees, there will be more yields of pine trees in the forest and it can save animals (wildlife) for their habitats

We can also do grafting to produce more pine trees because it usually takes a long time to grow a new one starting from the seeds. The advantages of grafting are: they will have the same generation and the quality of the yields will be the same like the first tree. The plant will also be ready and can plant the trees directly without the process of fertilization. The reproduction will also be faster through grafting. The disadvantage of this method is: the root is not strong enough comparing to the plants that grow starting from the seeds.
