The importance of proper watering can not be stressed enough for your container garden plants. Container Gardens are exposed to wind and sun so they dry out quicker than plants in the ground. There are no exact rules about watering your container garden plants. You have to become acquainted with the needs of various garden plants. The best tip is to examine them daily and water the plant when the surface of the soil begins to look dry. Feeling the soil will also help you determine the moisture needs of your container garden. Or, take the easy way and invest in a water meter if you are not sure.
How much and when to water will depend on the kind of plant and soil, the type and size of container, and the amount of exposure to sun and wind. Climate and the weather also play their part. During hot spells most plants in your container garden need daily water, except those in small clay pots, which may require it twice. Some plants, like fuchsias and tuberous begonias, wilt when dry, but geraniums and succulents are not so sensitive to neglect. On the other hand, it is good to let soil dry out a little between watering. This results in the soil from depleting its nutrients.
Since unglazed containers dry out quickest, watch them more closely. Wooden tubs, window boxes, and planters dry out more slowly; metal is the slowest of all. Groups of plants in large containers keep moist longer than single specimens. A good technique to avoid excess dryness is to have groupings of plants, arranged close together. This allows the container plants to shade one another to keep cool and stop moisture evaporation.
There are several methods of watering the plants. If you have many containers in your container garden, depend on the hose, allowing water to flow slowly and gently. Water small pots with a watering can that has a long spout or buy one of the self watering containers now available. When plants are grouped closely in a container garden, set up a sprinkler or hose with a fine spray nearby, allowing it to run for a long while, until the soil is soaked. In many states where the climate is dry, an automatic sprinkler system is a must to keep your whole garden hydrated. Remember this tip with geraniums and petunias, avoid sprinklers which spot blossoms.
One thing is certain; you must not depend on rain to keep your container garden plants hydrated. Even heavy showers deposit a surprisingly small amount of moisture, and without rains are frequent and lengthy, you must do your own watering. Remember those window boxes and other containers near houses or under trees can stay dry in spite of an all-day downpour.
Although it is essential to give enough water to your container garden, it is equally important not to over water and so cause root rot. Over-watering also prevails aeration of the soil, and will cause the plant to …
