Watering Containers
Method
Container plants usually need more frequent watering than plants growing in the ground. Their limited soil volume dries faster, especially in heat, sun, and wind. Good container watering keeps the root ball evenly moist without keeping it constantly saturated.
How it works
Water is applied until the potting mix is evenly moistened from top to bottom. Because containers dry from all sides and have limited storage, moisture can change quickly from one day to the next. Pot size, plant size, material of the container, and weather all influence how often watering is needed. Drainage holes allow excess water to leave, which helps protect roots from staying waterlogged.
Best for
It works best for patios, balconies, decks, small-space gardens, and any planting grown in pots or other containers. It is especially important for vegetables, herbs, annual flowers, and recently planted containers that can dry rapidly.
Tips
Check containers often in hot or windy weather because they may dry much faster than garden beds. Water the entire root area evenly instead of adding a small splash to only one side of the pot. Grouping containers and using mulch on the potting surface can help slow moisture loss.
