The first thing to consider is that shaded slopes, valleys with limited sunlight, areas surrounded by large trees or tall buildings, and other poorly lit locations are not ideal for planting. Fruit trees such as peaches, plums, apricots, cherries, and cherimoyas are high-light plants. If they don’t receive enough sunlight, their branches may die back, flowering becomes difficult, fruit set rates drop, and the flavor of the fruit becomes weak and unappealing.
Secondly, it's not advisable to plant fruit trees in paddy fields, along the edges of reservoirs, at the end of rivers, near streams, lakes, wetlands, or any areas prone to flooding. Most fruit tree roots are sensitive to excessive moisture. When the soil becomes waterlogged, the roots can rot, leading to weak, unhealthy trees, poor fruit quality, and lower yields.
Third, fruit trees should not be planted in areas with poor, thin soil. Different fruit trees have varying root depths. Except for drought-resistant dwarf varieties, pears, figs, and waxberries are especially unsuitable for such conditions. Without proper moisture and nutrients, these trees are more likely to suffer from drought stress, resulting in early leaf drop, low productivity, and even the "big and small year" phenomenon where some years produce a lot and others very little.
Lastly, large-scale orchard planting is not recommended in areas with poor access or inconvenient transportation. The difficulty in moving materials in and harvesting fruits out can significantly increase production costs and reduce profitability. If you're planning to develop an orchard in such regions, it’s essential to prioritize road construction and maintenance to ensure long-term success and efficiency.
