Planting Cyprus grass - tips for growing in the house, flower bed and garden pond

Cyprus grass can be kept in a variety of ways. Either in the bed, in the garden pond or as a container plant in the house and in the garden.

The tropics and subtropics are home to the Cyprus grass (Cyperus). There, the plants occur in different types and can reach heights of up to three meters. But only with plenty of water. Because without sufficient water, the swamp plant cannot thrive. In addition, the water palm is not hardy. In our latitudes, Cyprus grass is therefore mainly kept as a houseplant. Or it needs a warm and protected winter stand in good time. Here are the 10 most beautiful varieties of Cyprus grass for home and garden.

Choose the right location


The water palm needs a warm and bright location all year round. In the house, it is ideal if the window seat faces west or east. The grasses also feel at home in a heated conservatory. Cyprus grass can therefore stand sunny. However, the blazing midday sun is not good for the plant. High humidity is also important. In winter, the plant is therefore not well placed directly above the heating. Dry heating air is therefore poison for the swamp plant.


Cyprus grass also likes to spend the summer outdoors. Ideal locations are the balcony and terrace or the pond edge. When choosing the location, you have to pay attention to a wind-protected place, because the delicate stalks quickly buckle in strong winds. Temperatures up to 30 degrees are no problem for the water palm. In winter, temperatures can be a bit lower, but should never drop below ten degrees. The air humidity should be at least 60 percent all year round.

Garden pond:

In the summer months, the garden pond is generally the best location for the Cyprus grass. However, only the pond edge or the shallow water zone are suitable as locations. The swamp plant must not be completely under water, otherwise the roots will start to rot. So place the plant pot only about five centimeters in the water. To do this, place the plant in a permeable plant basket that is common for pond plants. The Cyprus grass then obtains sufficient nutrients from the pond water, so that no fertilization is necessary. However, it is important that you support the delicate stems to protect them from breakage.

Select the right substrate

Cyprus grass has no special requirements for the substrate. However, moisture should be able to be stored. This works particularly well if you use plant soil that is particularly rich in humus. Adding clay to the substrate increases the ability to retain moisture. Since the plant tolerates waterlogging very well and even needs it for ideal growth, it is not necessary to create a drainage.

If the plant gets a sunny place in the garden pond, it does not place any special demands on the substrate. Necessary nutrients are sufficiently absorbed through the pond water. So that the plant gets a better hold in the water, it is advisable to add coarse gravel to the plant soil.

Planting Cyprus grass in the bed - step by step instructions

The best time to plant the Cyprus grass in the bed is at the end of April. Simply do the following:

  1. Select location.
  2. Dig out the planting hole twice the width of the root ball.
  3. Insert the plant.
  4. Carefully fill in the planting hole.
  5. Press on the earth and pour well.

Keep Cyprus grass in a bucket

Cyprus grass can of course also be kept in a bucket. For this purpose, the planter should be of sufficient size and of a particularly stable design. The plants form extensive root systems in the bucket and can even grow to heights of several meters. As a houseplant in a bucket, you can plant Cyprus grass all year round. The bucket has its advantages and disadvantages. Here is an overview:

+ Advantages:

If you keep the Cyprus grass in a bucket, you can better meet the needs of the swamp plant. In addition, you can take the bucket outside in warm temperatures and as soon as the thermometer falls back into the room or the winter garden without much effort.

- Disadvantage:

Container plants have a higher nutrient requirement than species cultivated outdoors. The Cyprus grass in the bucket must therefore be fertilized. The problem: There is a risk of over-fertilization. Water palms in the bucket also have to be transplanted more often because the roots spread very quickly in the container.

Keeping Cyprus Grass Hydroponic - How To Do It Right

The regular watering of the Cyprus grass can be complex and can often be forgotten. In this regard, maintenance is made easier if you decide to cultivate in hydroponics. The plant is not planted in conventional soil, but grows in lava granules, perlite or seramis. The water level indicator can then be read using a float attached to the planter. So you can always refill the required amount of liquid. For strengthening, the plants should receive a special fertilizer designed for hydroponics.

It is also possible to change a water palm from potting soil to hydroponic. Simply do the following:

  1. Take the plant out of the conventional soil.
  2. Remove plant soil as completely as possible.
  3. Water the root area for a few days.
  4. Rinse earth completely.
  5. Fill the container with the hydro substrate.
  6. Insert the plant.
  7. Fill up the planter with substrate.
  8. Add water until the mark on the water level indicator is exhausted.

Repotting Cyprus grass

The plant grows particularly quickly. Therefore, choose an appropriately sized planter. If the old planter is completely riddled with the roots of the water palm and the roots already protrude from the container, you should repot the plant as soon as possible. The new planter should then be a lot bigger - five centimeters are the minimum.

Before transplanting, it makes sense to divide the plant and grow two new plants in separate planters. You can then use the original planter again.
