Calibrachoa grows best in moist, but not water-logged soil. Water when the top inch or two of soil has dried out. Container-grown plants typically need to be watered more often than garden-grown ones. Do not water without checking the soil moisture content. Overwatering promotes root rot.
How To Tell If Calibrachoa Needs Watered
A key symptom of underwatering is wilted leaves. If the lack of water continues for a few days, the leaves will turn yellow and eventually dry out and die. The plant will not have the resources required to produce flowers during drought conditions. Overwatering invites diseases caused by fungal infections.
How Often To Water Calibrachoa
Check the moisture level in the soil every day for the first week after planting a calibrachoa. The plant is under stress adapting to its new home, and inadequate watering may result in its early downfall. Add water when the top inch or two of soil has dried out.
Once the plant has become established, it will become more drought tolerant and will be more able to bounce back. Water garden-grown plants once or twice a week if it doesn’t rain. Check pots daily, especially if they are not glazed or not made from plastic. Containers dry out more quickly, especially during hot, dry, or windy conditions.
Water calibrachoa based on your local weather conditions. Water more frequently during droughts and days when the temperature exceeds 90 degrees F.
Best Time To Water Calibrachoa
Water calibrachoa in the morning before 10 AM for best results. Avoid wetting the leaves during the middle of the day when the sun’s rays are strongest. Watering in the evening is acceptable, but water early enough so that the leaves have an opportunity to dry before nightfall. Fungal diseases are attracted to wet leaves. Water calibrachoa grows indoors at any time.
How To Water Calibrachoa
Step 1 - Check to see if watering is needed.
Press your finger into the soil to a depth of two inches. If the soil feels dry, your plant needs watering. If the soil is moist, do nothing.
Step 2- Add water to the soil.
Use a hose sprayer on a gentle setting or watering can to moisten the soil around the plant. Add enough water to wet the soil a few inches below the surface for garden-grown plants. Add water until it begins to seep out of the drainage hole for container-grown calibrachoa.
Step 3 - Repeat the process.
Check the soil moisture level in a few days if no significant rain has fallen. Check daily for container-grown plants during hot weather.
Calibrachoa Watering Tips
- Container-grown plants need to be watered more often than garden-grown plants.
- In hot weather, check the soil moisture level more frequently.
- Always use a container with a drainage hole to avoid water-logging the roots.
- Try to avoid wetting the leaves.
