Bearing all of this in mind, remember that a long, deep watering is always better than a lot of shallow, frequent waterings. The reason for this is that deep watering encourages grasses to grow deep roots, which makes them more drought resistant and less prone to problems from watering.

The watering needs of Blue sedge will vary depending on where it is planted. Generally, you should water this grass every week. In hot climates, once or twice a week watering in the summer may be necessary. In moderate climates, watering once every seven days or more may be enough. Grass in containers almost always need more frequent watering than grasses in the ground. But with a species such as this that can thrive in full sun or part shade, the location also matters. Shaded grasses need to be watered less frequently than in-ground grasses.

Like many types of grass, the blades may appear folded along their centers and thinner than usual when the roots lack sufficient water. Despite its drought tolerance, regular, deep waterings will reward you with a beautiful color.

In the wild, Blue sedge grows in open scrubland, where it would be subject to extreme heat, loads of bright sun, and intermittent rain. Because this grass is drought resistant, you might expect never to need to water it. But don’t let its hardiness fool you, Blue sedge still needs care and attention. Even though this hardy grass can handle harsh, dry conditions, gardeners agree that it thrives best with consistent water.

When first planted, Blue sedge will need more frequent water until it has established deep roots. For Blue sedge in pots, the soil will dry out quickly, especially if the pot is in hot, direct sun for a large part of the day. Test the soil every 3 to 4 days and water only when it feels dry. Blue sedgeed in the ground generally needs less watering, but that depends on the soil it is grown in. Heavy clay soil holds water for a long time and may feel dry at the surface while still retaining plenty of moisture below the ground. Sandy soils that drain quickly will need to be watered more often.

You can often tell if you are watering enough by the rate of growth of your grasses. Blue sedge during the hottest months of the year and has been known to double in size in a year’s time. If the weather is hot and the grass is not growing vigorously, you may need to adjust your watering schedule. In winter, you might be able to get away with watering only once a month, but you will still want to touch the soil to test for moisture.

During a growth cycle (in the warmest months), the grass will need more water than usual. But during winter and cooler months, the need for water will be dramatically reduced. The most important thing to remember about Blue sedge is that the soil it is planted in should always be allowed to dry out completely before adding water.

Morning sunlight is ideal for Blue sedge, but it can also tolerate some afternoon sun if the temperature is not too hot. To provide the perfect balance of sunlight, try planting Blue sedge in an area that gets partial sun, such as under a tree or on the east side of a building.

If Blue sedge is exposed to too much direct sunlight, its leaves may turn yellow, dry out, or even burn. You may also notice that the plant wilts or becomes stunted. To prevent sun damage, make sure to give Blue sedge some shade during the hottest parts of the day. You can use a shade cloth or plant Blue sedge near taller plants that can provide some natural shade.

If Blue sedge doesn't get enough sunlight, it may grow tall and lanky, with sparse foliage. The leaves may also turn yellow or pale green, indicating that the plant is not producing enough chlorophyll due to lack of sunlight. To remedy this, try moving Blue sedge to a sunnier spot, or prune nearby foliage to allow more light to reach the plant.
