Water is essential for your tree’s growth and survival, but too much water can be detrimental. How do you know you are watering enough? A sufficient amount of water is 1-3 inches of water per week.
If your leaves are wilting or scorching, even after watering the specified amount, check if there is too much water for your tree by digging down 6-8 inches and feeling the soil. The soil should not be soaking wet, but cool and slightly moist to the touch.
Unfortunately, the symptoms for over-watering are similiar to those of under-watering. Checking your soil is the best way to decipher one way or the other.
