The first consideration is that areas with limited sunlight—such as shady slopes, deep valleys, or places surrounded by tall trees and buildings—are not ideal for planting fruit trees. Species like peaches, plums, apricots, cherries, and cherimoyas require full sun to thrive. Without sufficient light, these plants may experience branch dieback, poor flowering, low fruit set, and a lack of flavor in the fruits.
Secondly, it's not advisable to grow fruit trees in waterlogged or overly wet areas such as paddy fields, near reservoirs, riverbanks, streams, lakes, wetlands, or flood-prone regions. Most fruit tree roots are sensitive to excess moisture. Overwatering can lead to root rot, which weakens the tree, reduces fruit quality, and lowers yield.
Thirdly, areas with poor or very shallow soil are also unsuitable for fruit tree cultivation. Different fruit trees have varying root depths, and most require well-drained, nutrient-rich soil. Trees like pears, figs, and waxberries, unless they are drought-resistant varieties, should not be planted in such conditions. This can result in drought stress, early leaf drop, low productivity, and even the "big and small fruit phenomenon," where some fruits develop properly while others do not.
Lastly, large-scale fruit farming is not recommended in areas with poor access or inconvenient transportation. The difficulty in moving equipment and harvesting produce increases production costs and lowers economic returns. If you plan to establish a large orchard in such locations, it's essential to invest in road development and maintenance to ensure efficient operations.
