Avocado Watering: Avoid the Root Rot Trap

Avocado Watering Guide: Expert Tips in 3 Key Points

  1. Watering Differences: Ground vs. Pots:

    • Ground Trees: Deep, infrequent watering is crucial. Soak the soil to 24 inches (60 cm) every 7-14 days, adjusting for weather. Allow the top 3-4 inches (7-10 cm) of soil to dry between waterings. Clay soils require even less frequent watering.
    • Potted Trees: Consistent moisture is necessary for potted trees. Water when the top 2 inches (5 cm) of soil become dry, likely 2-3 times a week in summer, and less frequently during winter. Use pots with multiple drainage holes and a gritty potting mix to ensure proper drainage.

  2. Recognizing and Avoiding Over/Underwatering:

    • Overwatering: Is the primary cause of root rot. Signs include yellow leaves, soggy soil, and a foul odor. If these appear, immediately cease watering and aerate the soil.
    • Underwatering: Watch for curling leaves and crispy edges. If these occur, slowly and thoroughly soak the soil to rehydrate the roots.

  3. Essential Practices and Pro Tips:

    • Mulching: For in-ground trees, apply mulch to retain moisture between deep waterings. However, keep the mulch 6 inches (15 cm) away from the trunk to prevent rot.
    • "Less is More": When in doubt, it's better to err on the side of underwatering. Avocados are more tolerant of dry conditions than overly wet ones. Use a soil probe or your finger to accurately assess soil moisture before watering.
