How Often to Water 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.

Grass garden - tips for selecting and caring for plants

With the fashion for the naturgarden style, ornamental cereals have come to our gardens. Exquisite compositions of herbs, delightfully contrasting with the candy beauty of garden flowers, imitate the corners of ennobled nature, sung by such eminent landscape designers as Piet Oudolf, Rosemary Weiss, Sarah Price and others.

blindly copying the author's compositions, but it's quite possible to single out a piece of the garden for them. And to make it easier for you, we have prepared recommendations for choosing herbs, planting and caring for them, and combining with other plants. nine0003

How to choose plants

About 1000 species of various cereals grow in Russia, more than 200 of them are highly decorative and are widely used in landscape design. How to navigate in this diversity and what to consider when choosing?

  1. Climatic conditions.

Herbs that will not freeze in the conditions of the Russian winter can be safely attributed to lightning, miscanthus, reed grass, soddy pike, fescue, grate, falaris, ryegrass . In the southern regions, you can also sow more heat-loving cereals - pampas grass, ornamental millet.

Chinese Miscanthus. The contrast of upward-pointing inflorescences and arching leaves makes it especially beautiful.

If it is in the shade or on the north side of the house, shade-tolerant forest-type grasses are needed - various varieties reed grass, blue lightning, oak bluegrass .

Steppe and alpine grasses will feel great in the sun - gray fescue, grate, feather grass, maned barley, cylindrical imperial .

sedge, cattail, soddy pike, reed falyaris, miscanthus will take root on the shore of the reservoir.

An openwork lightning creates a transparent veil, especially effective in the rays of the setting sun.

  1. Decorative features. nine0016

When choosing, take into account the height and habitus of the bush, the rate of its growth, the shape of the inflorescences, the period of the highest decorative effect.

So, if you need low cereals for an alpine hill or for decorating a border, gray fescue, bulbous ryegrass, gray keleria are suitable.

cortaderia, miscanthus are used to create accents and solitary plantings.

If you plan not to cut flower stalks for the winter, you need those that will not break under the first gusts of winter wind. Various varieties will perfectly cope with this task.0019 miscanthus, sharp-flowered reed grass (Karl Foerster variety), spreading rush, reed.

Due to the red foliage of the emperor, cylindrical is suitable for creating accents in the composition

When and how to plant, what to combine with each other

Most ornamental grasses are perennial plants, therefore once grown from seeds, they are subsequently propagated by dividing the bush. Heat-loving cereals ( Imperata cylindric, pinnate, African millet ) we grow it as an annual crop or cover plantings for the winter.

Hybrid forms are purchased in nurseries and planted as seedlings, species can be grown from seeds on their own. Since the seeds need long-term stratification, they are sown in autumn in boxes and left in the cold, for example, they are dropped into the ground and covered with peat on top. In the spring, the peat layer is removed and the grains are allowed to germinate. The grown seedlings are planted in a permanent place in early summer.

You can divide the bush both in spring and autumn. To do this, they dig it out, divide it into parts of 7–10 sods each, and transplant it to the chosen place. nine0003

The site for planting is prepared depending on which soil the plant prefers. If necessary, drainage is poured into the bottom of the landing hole, the soil is loosened with sand or peat.

Cereals do not need highly fertile soil. On the contrary, in order for the root system to be powerful, it is better to keep them "from hand to mouth"

Herbs are combined with each other, primarily based on agrotechnical preferences. So, you can select several groups with similar queries.

The better the combination of grasses, the more natural the composition will look

Caring for ornamental grasses

In the spring, as soon as the snow melts, it is necessary to remove last year's grass residues, thereby accelerating the start of new greenery. Otherwise, care for cereals is the same as for other garden plants - timely weeding, loosening, if necessary, watering.

To keep weeds from sprouting and preserve soil structure, we recommend mulching plantings with decorative gravel or pebbles. nine0003

In the second or third year, the plants can be fed with complex fertilizers at the rate of 30–40 g/m². They are dissolved in water or embedded in the soil in the root zone.

In autumn, the brittle flower-bearing stems are cut off so as not to spoil the winter landscape, and the strong and decorative ones are left until spring.

How to use in the garden and what plants to combine with

Ornamental grasses are not by chance so popular in garden design. They create an atmosphere of lightness and naturalness in the garden, add volume to compositions, balance large inflorescences and bright colors. Consider options for their use. nine0003

Monogarden from cereals

Monogardens are such compositions in which plants of the same type occupy at least 80%. When creating a cereal corner, combine high ( miscanthus, cortaderia ), medium-sized ( maned barley, pinnate, feather grass, soddy pike ) and low ( fescue, ryegrass ) grasses.

Select the other 20% of plants to add shape and color. Umbrellas go well with cereals yarrow and stonecrop , spherical inflorescences monarda, burnet, mordovnik , candles foxglove and delphinium , "chamomile" echinacea and rudbeckia .

Do not allocate more than 15–20 m² for a grass corner, otherwise it will look boring and monotonous.

Different types suitable for rock gardens and rockeries fescue, mountain sedge, faliaris, maned barley . They will make a good combination with conifers , they will be perfectly complemented by wild plants and perennials - wormwood, bluebells, subulate phlox, stonecrop , sedum .

In rockeries, cereals are planted in such a way that after pruning for the winter, the emphasis shifts to beautiful monoliths, trees and there are no bald spots in the composition. nine0003

In large flower beds, it is recommended to use large structural cereals - Sugarflower miscanthus, blue lightning, pennisetum bristly, erianthus . delphinium, sage, veronica, liatris, peonies , astilba will suit them as satellites.

If you love roses , fescue, oats, maned barley, mountain sedge will help to emphasize their beauty and grace.

In country flower beds with dahlias, crocosmia, rudbeckia , Phloxes perfectly match ornamental millet, soddy pike .

Large cereals create the volume and rhythm of the composition

By the pond

There are many cereal crops that easily tolerate flooding and love moist soil. These are various types of reeds , cattail, sedge . The water also likes to grow miscanthus, reed falyaris, filamentous rush .

Decorate the shoreline with Siberian irises, marigolds, bruners and other water-drinking herbs

In containers

Lately it has become fashionable to plant grasses in containers. They can be used to fill a flower garden, create a background, or, arranging in height, color, create independent compositions.

Container plantings are a great decoration for a terrace or patio

Ornamental grasses and cereals - 10 plants for your garden

Flower gardens, which were based on ornamental shrubs and perennials, have long sunk into oblivion. Natural flower garden - a favorite of recent years. The style of such flower beds is called the "New Wave". They create a complete sense of harmony and freedom. The basis of such compositions is bulbous, perennials and ornamental grasses. In conversations, you can often hear about tulips, lilies, various types of perennials, but very rarely anyone talks about ornamental cereals. But in vain! A fashionable original site cannot be imagined without representatives of the cereal family, of which there are a huge number of species and which are perfectly combined with other plants or look graceful in single plantings. They can decorate a rockery, an alpine hill, place it near a decorative pond or along a path. We offer to get acquainted with the most interesting of them. nine0003

Features of ornamental grasses and cereals for the garden

Before diving into the world of beauty, let's talk a little about the features of growing cereals in the garden. Ornamental cereals are divided into annual and perennial crops. We will focus on perennial cereals. These are unpretentious plants that endure all the vagaries of the Ural weather. They grow in one place for many years and require a minimum of care and top dressing. Despite their simplicity, ornamental grasses are incredibly beautiful not only in summer, but also in other seasons. nine0003

Grasses amaze with their diversity and ability to survive in drought and perfectly adapt to flooded areas:

In addition, ornamental horticultural grasses have different root systems and are divided into:

This knowledge will help you to properly place the plants on your site.

Next, we can separate the cereals for the period of awakening after winter. This is:

cold-growing cereals - awaken early in spring, quickly gain green mass and slow down growth with the onset of heat:

Warm-growing cereals - awaken late when the soil warms up well:

These plants love warmth and therefore show the first signs of life only when the soil warms up for real. They then grow rapidly. And bloom in the middle of summer.

Due to its unpretentiousness, ornamental grasses in the garden can be grown not only by a professional gardener, but also by a beginner.

Propagation of ornamental grasses

Ornamental grasses for the garden are propagated by dividing the curtain in early spring or by sowing seeds. Seeds are sown in early February. In the first year, the seedling bushes that have appeared are grown on a separate ridge, in order to avoid oppression by other plants. In the second year, the grown plant is planted in a permanent place, taking into account the further growth in the size of the curtain and height. nine0201 Annual grasses can be sown directly into the ground in spring. These include - ornamental corn, black sorghum, setaria (bristle), canary grass, millet, pinnate, lamarckia, haretail.

The shape and size of ornamental grass curtains is the most diverse. There are undersized ones that look great in rocky gardens, along the edge of the path. Medium-sized and tall cereals occupy a leading place in flower beds. They are perfectly combined with coniferous plants and shrubs of spherical shape. They get along well with various plants - burnet, euphorbia, stonecrop, phlox, "chamomile" perennials. nine0003

Our top ten herbs for the flower garden

1. Blue fescue is a hardy perennial plant that looks very much like a fluffy tussock. Height up to 25 cm. Winters without shelter, grows rapidly and in the second year the curtain can be divided into two parts. Prefers open sunny position and light fertile soil with good drainage.

4. Reed grass is a beautiful perennial plant, unpretentious, but it can be covered in winter to avoid freezing. Feels good on heavy clay soils. It grows very quickly, easily tolerates drought, prefers both sun and partial shade.

Combines very nicely with daylilies, lupins, loosestrife, aconites, anemones, hostas and perennial asters.

5. Evergreen Sheep is a very beautiful blue-silver shrub that is often confused with fescue. The reason for this is a similar shape, but the tussocks of sheep are much higher and more spreading, 30-50 cm high, up to 1 m in diameter. Likes a sunny and dry location. Doesn't like overflow. Does not tolerate transplant well. nine0003

In the neighborhood with coniferous, red-leaved and yellow-leaved barberries and vesicles, with early-flowering small-bulbs, it looks very chic.

6. Pennisetum bristly is a beautiful perennial plant that can give airiness and a unique look to the flower garden.
