Hydrangeas in pots should be watered frequently enough to keep the soil consistently moist but not waterlogged. Here are the key guidelines for watering potted hydrangeas:
- Water thoroughly about every 2 to 3 days or as needed, depending on weather and pot size. In hot, sunny conditions, daily watering may be necessary, while cooler weather allows for watering every other day or less often
- Check soil moisture regularly by feeling the soil. Water when the top inch feels dry to ensure the roots have enough moisture without sitting in water
- Water deeply until water drains from the bottom of the pot to ensure the entire root ball is hydrated
- Avoid watering the leaves directly to prevent leaf burn or fungal diseases; water at the base of the plant instead
- In warm weather, water early in the morning or in the evening when the plant can best absorb moisture
- Be cautious not to overwater, which can cause yellowing leaves and root rot. Well-drained soil and pots with drainage holes are essential
- For indoor hydrangeas, watering once a week with occasional soaking is often sufficient, but adjust based on indoor humidity and temperature
In summary, potted hydrangeas typically need watering every 2 to 3 days in warm weather, less frequently when cooler, always ensuring the soil stays moist but not soggy. Monitoring soil moisture and the plant’s appearance (wilting or yellowing leaves) will help you fine-tune the schedule.
