Watering ornamental grass

Watering ornamental grass

Growing ornamental grasses are a popular gardening hobby. These grasses are valued for their beauty and can be planted in many different types of gardens. They can grow in a range of soil conditions and some varieties are drought-tolerant, requiring little to no irrigation. Ornamental grasses also help keep pests away and provide shelter for birds, small animals, and insects.

In this article, we’ll be taking a look at how often to water your ornamental grass. The answer will vary depending on a bunch of factors. We’ll analyze those factors and how they affect your ornamental grass’s watering needs.

How often to water ornamental grasses

When it comes to how often to water ornamental grasses, the answer depends on a variety of factors. For example, is the ornamental grass planted in a pot or in the ground? Is it in direct sunlight or does it only get a partial day of direct sunlight? What has the weather been like recently?

Generally speaking, the best way to determine how often to water your ornamental grass is to check the top half-inch of soil for dampness. As a rule of thumb, if it’s dried out, give the ornamental grass some water. If it’s still damp or moist in the top half-inch, then no need to water the ornamental grass.

Watering ornamental grass seedlings

When it comes to how often to water ornamental grass seedlings, you want to make sure you give your young ornamental grass the water it needs for its early growth.

Sometimes ornamental grass seedlings are grown in bunches. These may soak up moisture faster, so keep tabs on the dampness of the soil for these seedlings.

It’s best to water them lightly more frequently than watering them a lot less frequently. Seedlings are more susceptible to “drowning” when they are overwatered. Too much water at once can also cause the plant to uproot itself, as soil washes away easier when the plant doesn’t have a solid root structure in place.

Plan on watering your ornamental grass seedlings every few days, or even daily. Keep an eye on the surface level dryness of the soil, and give the seedlings a sprinkle if it doesn’t look moist.

Ornamental grass seedlings are faster to show it if they don’t have enough water, so if the plant is wilting and the soil is dry, not enough water is probably the problem.

Watering an established ornamental grass

Established ornamental grasses should be watered when the top half-inch of soil is dry. Below are specific growing scenarios and information on how often to water the ornamental grass for each.

When to water ornamental grass that is planted outside

Ornamental grassed outside is often healthier, as there’s more chance of direct sunlight, and airflow generally helps to protect it against disease.

Plan on watering your established ornamental grass a few times a week when it’s planted outside. If you’re not sure whether it needs to be watered, you can check if the surface level soil is moist, or if the ornamental grass is wilting.

When to water ornamental grass that is planted inside

Ornamental grasses that are planted inside may not need as much water, as direct sunlight is normally not available. Be extra careful that you aren’t overwatering the ornamental grass inside.

If the ornamental grass is wilting, that could be a sign that it is under or over-watered. Keep track of how moist the soil is to know the difference before watering the ornamental grass more.

When to water ornamental grassed in the landscape

Ornamental grass that are planted in the landscape is able to pull up some moisture from the ground, so it won’t need to be watered as much as ornamental grasses are grown in a container.

When to water ornamental grassed in containers

As mentioned previously, ornamental grasses that is planted in a container will need to be watered more frequently since they don’t have natural water in the ground as a source of hydration.

Things to consider

There are numerous factors to consider when determining how often to water your ornamental grass. Factors like weather, sunlight, the season of the year, and spacing all play a rule.

Weather

Spring weather is generally rainier in some areas, so you may not need to water your ornamental grass as much. Be careful that you don’t overwater your ornamental grass in a season with a lot of rain.

Sunlight exposure

Most ornamental grass varieties grow great in full sunlight, but in the heat of the summer, you’ll need to keep these plants watered well. 

ornamental grasses that are grown in full sun will dry out fast, especially if they are getting direct sunlight during the noon of the day.

Keeping the ornamental grass well watered in these seasons ensures that they’ll be able to produce healthy new shoots of fresh ornamental grasses in the future.

Season

Depending on the season, you may not need to water your ornamental grass as much. In the fall, when the ornamental grass is more established and the cooler weather sets in, you may only need to water the ornamental grass once a week.

Spacing

Ornamental grasses that are planted close together will compete for the same water, and as a result, you’ll need to water them more.

Tips for watering your ornamental grass

Here are some tips for watering your ornamental grass.

Your ornamental grass may wilt with too much water or too little

Keep in mind that a ornamental grass that is wilting does not necessarily always need water. Sometimes ornamental grass wilt when they have too much water.

Always check the soil dryness to determine if you should give the ornamental grass some water.

It may not be a watering problem, but a fertilizing problem

If the plant is wilting or looking yellow, it may not be your watering that is the problem. You may want to check the fertilizer level of the soil it’s planted in to see if that’s the problem.

Make sure your pot has adequate draining

If you are planting your ornamental grass in a pot, it’s very important that the pot has proper drainage. ornamental grasses are susceptible to root rot if water does not drain through the soil, so well-drained soil is essential.

Repotting

If the ornamental grass needs watering a lot, you may want to re-pot the plant so that it has more soil to spread its roots in.

Recap: watering your ornamental grass recap

In conclusion, there are many factors that will affect how often you’ll need to water your ornamental grass. The best and most simple thing to do is check the moisture level in the top half-inch of soil to determine if it needs some water.
