Common problems:

  • You can bring your avocado plant outdoors during the spring, once the weather warms up. But once it starts to go below 50º Fahrenheit / 10º Celsius you should bring the plant back indoors or else you will notice the leaves wilting and falling off.
  • A sign of over fertilization, is a white crust on the soil which is a salt build-up from the fertilizer.
  • Overwatering your plant can also lead to the leaves turning yellow, and while the plant does need lots of moisture, be sure that there is a good drainage system to help avoid over watering, leading to root rot.
