Watering plants might seem like a no-brainer, but be careful.
Moderation and timeliness are the key.
You don't want to drown your garden plants or shock them with drought either.
In general, new plants should not be allowed to dry out completely until they are well established, usually one to two years.
How often you need to apply water in order to achieve this balance will vary depending on the plant size, habit, drought and wind conditions and soil type.
Water should be applied right at the base of the plant for the first season, since that is where all the roots are until the plant establishes new roots into the surrounding soil.
Often, a sprinkler will only wet the soil around the new plant without wetting the root ball. Water should be applied slowly so it has a chance to soak in and not run off.
Following these simple tips, paying attention and using common sense will quickly familiarize you with what your garden needs.
