So take advantage of planting the south and east , where the land is flat and more light . As anti -term crops appropriate to the type of soil or rock mountain fences in rural and coastal areas , soil particles stick rate of 20 % , 40 % sand , 40 % soil particles will help the dragon fruit tree to absorpt nutrient , monthly rainfall from 50 – 100mm, the tree will grow and develop well .
