Planting papyrus, cyperus

Papyrus sedge is a plant native to marsh areas, which explains its constant need for water.

Preferably in spring. You can choose a special aquatic plant soil mix.

  • The plant must continuously bathe in water.
  • It is thus perfectly suited to ponds and embankments.
  • For pots, place the pot in a saucer that is always filled with water.

Propagation is possible through crown division in spring.

It’s a very fun activity to also propagate your papyrus from cuttings.

  • Cut a stem about 6 inches from the top (15cm).
  • Dunk it in a glass of water upside-down, with the clump of leaves underwater.
  • Change the water every three or four days.
  • After a couple weeks, roots will appear and a few weeks later, new sprouts!

At this point, you can transfer it to a pot with soil.

Pruning and caring for papyrus

Pruning isn’t really required, even though the papyrus isn’t harmed by pruning at all.

However, you must remove dry stalks as they appear, and you’ll notice that new shoots will sprout again full of energy.

Papyrus in pots or garden boxes

In Spring, ideally, you would repot your plant into a pot with a diameter that is slightly larger than the previous. If you can’t get to it every year, do try to do it at least every 2 years.

Growing your papyrus as a potted plant indoors is an excellent way to increase moisture in the air for other plants. For instance, plants like orchids, Stephanotis and other tropical plants love humid air. Since papyrus basically wallows in water, it’s an excellent plant to have near your other houseplants!

Where to grow papyrus: pond, pot or indoors

Papyrus will grow in very different settings, provided the roots never dry out. Here is how each situation supplies that constant water, and what to watch for.

Where to grow papyrus: pond, pot or indoors
Setting How water is supplied Point to watch
Pond or embankment Roots permanently in the water of the pond Ideal position, nothing to top up
Pot outdoors Pot stood in a saucer kept filled with water Saucer must never run dry
Pot indoors Base of the pot soaked in a container of water Raises air moisture for nearby houseplants
Garden box Watering and standing water in the box Frost can kill the plant outright

Whichever setting you choose, the rule never changes: the feet stay in the water.

Papyrus in winter, resistance to freezing

The papyrus isn’t very hardy and will not survive temperatures lower than 23°F (-5°C), especially if over a longer span of time.

In garden boxes, take note of this because freezing could condemn your papyrus just because of the first frost spells.

Best to anticipate and bring your papyrus indoors to a spot protected from from freezing.

Indoors, stand the papyrus in the brightest spot you have, such as a veranda or conservatory, rather than a dark garage or cellar.

Learn more about papyrus

This magnificent plant native to tropical areas has evolved into several hundred species, each being more elegant than the next.

There are thus a number of differently shaped leaves, sizes, and shapes for this uncommon perennial.

This plant is very easy to care for and only asks for water to bask in for it to develop rapidly.

When growing it in pots and as an indoor plant, it is important to soak the base of the pot in a container that is constantly filled with water.

Papyrus and paper

Long used as a base material for paper, that is actually the reason why old scrolls are called “papyrus”.

Indeed, papyrus paper is an ancient paper production technique, where very thin slivers from the papyrus stem are superimposed on one another. They’re woven into a mat and then pressed together between two heavy flat stones to dry.

Frequent papyrus problems and diseases

Papyrus care is easy
Yellow leaves point to too little water, warmth or light

Leaves turn yellow: this is generally connected to a lack of water or to temperatures that are too low. It may also be due to a lack of light.

Whatever the case, add more water, check that the room is at least 60°F (16°C) warm, and give it as much light as you can.

In case aphids attack, follow our recommendations to fight against aphids.
