Summer is the most difficult time for container plant watering. It is a challenge to gauge how much water for container garden plants is necessary. There is a fine line between drought and soggy soil, and either one can be detrimental to plant health.
Container plants outdoors need more water than those indoors because of higher temperatures, direct sunlight and wind tend to dry soil quicker.
When to Water Container Plants
The optimal time to water your containers is early morning or early evening. This is when temperatures are cooler, allowing moisture to seep down to the roots but excess water on the plant also evaporates quickly enough so it is not vulnerable to fungus.
It is also a good indication that water is needed when the first inch or so of soil is dry. Keep an eye out for shriveled leaves, limp stems, dropping petals, and dry, discolored leaves.
How Often to Water Potted Plants
Frequency depends on the species of the plants. For example, succulents and drought tolerant plants need to be watered less often than annuals and vegetables.
For most plants, it’s best to water deeply and slowly so water can access all parts of the soil and roots. This will also force over dry potting soil to absorb water again.
Tips for Watering Outdoor Potted Plants
- Use glazed pots to help prevent evaporation OR when using clay pots, place it in another container
- Apply a layer of mulch or rocks to the soil surface to slow moisture loss
- Set up a drip irrigation system to allow for slow and even watering
