In the ground, watering issues can be solved, but In a container, too much or too little water will kill Hairy bamboo in short order. When Hairy bamboo 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 Hairy bamboo has been improperly watered, the first thing to do is figure out if the problem is too much or too little. If your Hairy bamboo is getting too much water, stop watering it immediately. Sometimes it can take weeks for heavy soils to dry out, so be patient.

The solution for Hairy bamboo 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 Hairy bamboo?
The watering needs of Hairy bamboo 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. Hairy bamboo 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, Hairy bamboo 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, Hairy bamboo 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, Hairy bamboo will need more frequent water until it has established deep roots. For Hairy bamboo 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. Hairy bambooed 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 Hairy bamboo 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. Hairy bamboo 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 Hairy bamboo is that the soil it is planted in should always be allowed to dry out completely before adding water.
How much/long should Hairy bamboo get sunlight per day for healthy growth?
For healthy growth, make sure that Hairy bamboo receives at least 3–6 hours of sun each day. This is actually a minimum requirement—most plants that can handle part sun can also thrive in full sun, but because they require less light for photosynthesis, they are more flexible than plants that require full sun or part shade.
What type of sunlight does Hairy bamboo need?
Hairy bamboo does best with exposure to full or part sun. They will perform best with direct morning light, but in summer they need protection from the strong afternoon sun. In temperate environments, too much hot afternoon sun can burn the leaves, damaging the plant's appearance and health.
Can sunlight damage Hairy bamboo? How to protect Hairy bamboo from the sun and heat damage?
Hairy bamboo planted indoors can easily be damaged by direct sunlight when it's moved outdoors. The best way to prevent sunburns from overexposure is to move pots gradually from a shaded area to a brighter spot, gradually. But even plants that are acclimated to the summer sun can be damaged by extreme heat. In a heatwave, it is important to keep the soil consistently moist so that plants can cope with excessive levels of heat. Moving plants in containers to areas with afternoon shade or erecting a shade cloth over them can protect sensitive Hairy bamboo during extreme weather events.
Does Hairy bamboo need to avoid sun exposure? / Should I protect Hairy bamboo from the sun?
While bright morning sun and some full sun exposure can be highly beneficial for Hairy bamboo, the harsh, hot midday sun of summer can be too much to handle. If planted in the ground, the summer sun will usually ramp up slowly enough through the season for Hairy bamboo to gradually adapt to its intensity. But a potted plant that has been indoors or in a protected location will often suffer injury when placed suddenly into a location where the direct summer sun reaches it in the hottest part of the day. To protect this plant from the brutal afternoon summer sun, plant or place it in an understory location where it is shaded at midday by taller trees and plants or by a building or landscape feature.
What will happen if Hairy bamboo gets inadequate sunlight?
When Hairy bamboo receives too little sun, they may become pale green or display drooping, yellow leaves. While some leaf drop is normal, if leaves are dropping but no new ones are growing in to replace them, it is a sign that something is wrong. If Hairy bamboo receiving inadequate light does manage to grow, the new growth is often spindly, pale, and prone to insect infestation. Paying attention to these signs and changing the lighting conditions of the plant will make a significant difference.
Does Hairy bamboo need special care about sunlight during its different growth stages?
Tender, new leaves are especially sensitive to sunburn. Bearing this in mind, very young Hairy bamboo and when it's in a strong growth phase, such as in late spring and early summer, will be more sensitive to harsh sun and heat than the mature one or those in a more dormant fall growth stage. Hairy bamboo fresh from a nursery is also usually not prepared for strong full sunlight and must be introduced to it slowly.
Are there any cautions or tips for sunlight and Hairy bamboo?
Recently transplanted Hairy bamboo will often experience a bit of shock and will need to be cared for carefully, either shaded from bright afternoon sun or placed in a protected area. On very hot days, you may see the leaves of Hairy bamboo drooping—this is usually nothing to worry about. Plants will send the water in their leaves down into their roots to protect them from burning. However, if the leaves are still drooping in the evening or the next morning, the plant needs water. Always avoid watering during the hottest times of day, as sunlight can hit wet leaves and scorch them easily. Hairy bamboo that has been underwatered will be weaker than that with consistently moist soil. This can leave it with weak roots that are unable to protect the leaves on hot, sunny summer days by diverting water away from the leaves. Care for an underwatered plant by giving it a long, deep watering and then allowing the top two inches of soil to dry out before the next watering. Even if it loses its leaves, if cared for properly it will grow new ones.
