Nine measures for high-yield cultivation of pomegranate
First, choose warm, sunny, leeward, well-drained, neutral or slightly acidic soil, with slightly clayey soil being the best. Heavy clay, thick pericarp, black spots, dehiscent fruit; lack of light, poor growth, small fruit, light taste, low yield; freezing injury when the temperature drops to-18 ℃.

Sixth, before pruning and sprouting, remove overdense, overlapping, overgrown, disease and insect pests, withered, basal germinating branches. Short truncated elongated branches (25-40 cm cut) and 2-3-year-old fruiting branches.
