Container grown plants dry out quickly and require more water than their backyard counterparts growing in open soil. This is because potting soil is often lighter and less compact than regular garden soil and the water holding capacity around the plant is determined by the size of the container. Watering potted plants once a day or even twice daily may be necessary, especially if the weather turns hot and windy or your containers are in full sunlight. Watch closely, and check moisture levels often. If the growing media appears pale or cracked, or feels dry below the soil’s surface, it’s time to water.
The easiest way to water container plants is with a watering can or gentle hose. However, when you water make sure that you are watering the soil and not just the plant’s leaves. Continue watering until it runs out the drainage holes in the bottom of the pot. The idea is to water thoroughly but allow enough time between waterings for the soil to begin drying out. A moisture meter, available at many garden centers, can be used to instantly determine when to water your plants. If the potting mix remains soggy for too long, air will be forced away from the roots and your plants may suffocate or drown. (more…)
