How much water per day in summer does 4' new planting apple trees require?

Newly planted Apple trees typically require about 10 to 15 gallons of water per week during the summer months, which translates to approximately 1.5 to 2 gallons per day. It's important to water deeply but less frequently to encourage deep root growth. Factors such as soil type, temperature, and humidity can also influence their water needs, so monitoring soil moisture is essential. Adjustments may be necessary based on specific weather conditions and tree health.
