Prof. Samuel Fitzgerald, Ph.D.Watering container plants If they feel dry, take your finger and bury it in the soil up to the second joint. When the earth at the top feels dry, water thoroughly at once. This simple method will keep plants to the last drop of water without risk of scorches from drought or of opaque roots from excess moisture.
Environmental Influences
- Small pots dry faster than large containers
- Hot sunny days increase water needs significantly
- Wind accelerates evaporation from soil surfaces
- Humid conditions reduce watering frequency needs
Plant-Specific Needs
- Fruiting plants require more water when producing
- Succulents need less frequent watering intervals
- Seedlings need gentle consistent moisture
- Mature plants tolerate brief dry periods better
Deep watering: Water deeply enough so that it flows out of the drainage holes. This trains the roots to keep reaching down to search for moisture. Do not water only enough to moisten the surface, or the plant will breed surface roots that are vulnerable to drought during hot spells.
The rate at which moisture evaporates from container plants is also influenced by the material used to make pots or troughs. Unglazed pots absorb water more readily into their sides than plastic or glazed terracotta. In very hot weather, when plants are suffering from drought, place them on trays containing pebbles and water, thereby increasing the humidity without necessarily saturating the roots.
Adjustments should be made according to the changing seasons. Summer may require daily plant checks, while winter may only require weekly monitoring. Watch for droopy leaves or yellowing leaves, which are signs of stress. Be sure to keep a gardening journal, so you can determine what works for you and your plants, as well as their unique microclimates.
