What should I do if I water my Spike Bentgrass too much or too little?
Without proper watering, this beautiful ornamental grass will underperform. In the ground, watering issues can be solved, but In a container, too much or too little water will kill Spike Bentgrass in short order. When Spike Bentgrass isn't receiving the right amount of water, it may stop growing. In the case of overwatering, it will begin to display yellow leaves with brown tips. Underwatering can produce drooping leaves, weak seed head production, and browned leaves. If you suspect your Spike Bentgrass has been improperly watered, the first thing to do is figure out if the problem is too much or too little. If your Spike Bentgrass is getting too much water, stop watering it immediately. Sometimes it can take weeks for heavy soils to dry out, so be patient. At the first sign of new growth, test the soil for moisture and decide whether it needs more water or not. The solution for Spike Bentgrass receiving too little water is even simpler: give the grasses a nice, deep drink and see if it perks up.
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.

How often should I water my Spike Bentgrass?
The watering needs of Spike Bentgrass 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.
Spike Bentgrass should only be watered when the soil is dry. If you’re unsure when to water, there are a few key signs you can use as your cue. Pressing your finger a couple of inches into the soil will tell you if the soil is dry. For a potted grass, you can weigh the grass with a portable scale to see how light it is, but you can also quickly feel when the pot is light from lack of water. 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, Spike Bentgrass 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, Spike Bentgrass 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, Spike Bentgrass will need more frequent water until it has established deep roots. For Spike Bentgrass 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. Spike Bentgrassed 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.

What should I be careful with when I water my Spike Bentgrass in different seasons, climates, or during different growing?
You can often tell if you are watering enough by the rate of growth of your grasses. Spike Bentgrass 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 Spike Bentgrass is that the soil it is planted in should always be allowed to dry out completely before adding water.
