apple tree maintenance
Climatic requirements
The apple tree is a species of temperate zones, it requires a long period of vegetative rest to satisfy its needs in cold which are of the order of 800 to 1600 hours below 7.2°C.
The species can withstand temperatures as low as -35°C in the dormant phase, but the most favourable areas for cultivation are those with cold winters and moderately hot and relatively humid summers.
Edaphic requirements
The apple tree adapts to a wide range of soils. However, well-drained, slightly acidic (pH 6.5 to 6.7), silty-clay, deep and rich in organic matter soils are the most favourable for apple growing.
Water requirements
The amount of water needed by the apple tree for its growth and production varies from 700 to 900 mm/year.
The water requirement of the apple tree during the growing season (March to September) would be 600 mm. The highest needs occur in July-August.
