Excessive heat can cause the leaves to turn yellow and die. Choose a location that is bright but not directly lit by the sun. In summer the perennials can be planted outside in a partially shaded location. Since cup primroses are not hardy, they have to be returned to the house before the first frost at the latest.

Care of the cup primrose

Make sure that your cup primrose is always supplied with sufficient water so that the soil never dries out. When waterlogged, however, goblet primroses begin to rot. You can optimize the water supply by adding coarse gravel to the potting soil. Water the houseplant with lukewarm, low-lime water and fertilize the cup primrose every two weeks with liquid fertilizer.

Caution: risk of allergies

The hairs of the goblet primrose contain the toxin primin, which can irritate the skin and trigger allergic reactions. While a single touch usually has no consequences, repeated contact can inflame the skin. Especially when there are children in the house, it is worthwhile to try reduced-prim varieties like "Twilly Touch Me" to acquire.

Bow hemp is a houseplant that is forgiving of small mistakes in care, thrives well and can reach a handsome age. Here you can find out what you should consider when choosing the location and when caring for the bow hemp.

Features of the houseplant

Bow hemp belongs to the asparagus family and is found all over the world, especially in Africa and the Arabian Peninsula. The plant is evergreen and forms underground rhizomes. The leaves have no stem, an upright habit and are often arranged in rosettes. The plant grows very slowly and can live for many years, which is why stature heights of several meters are not unusual under ideal growing conditions. There are 67 species of the plant, with the species Sansevieria trifasciata being kept as a houseplant.

Location and light

Bow hemp feels good in most places, but thrives best in a location that is as sunny as possible. If it is kept as a houseplant, the bow hemp can stand on a south-facing window and can withstand a lot of direct sunlight. Even though bow hemp is an easy houseplant to care for, you should avoid a location with a temperature below fifteen degrees Celsius and drafts. Tip: In the living room at normal room temperature, the plant can be left standing all year round without much maintenance.

Bow hemp: tips on care

Since the plant comes from the desert, it gets by with very little moisture. Therefore you should only water your bow hemp sparingly and avoid waterlogging in any case. If you want to fertilize your bow hemp for maintenance, it is sufficient to add some liquid fertilizer to the irrigation water once a month. The best time to repot the houseplant is in the spring, when you notice that the old container is getting too small.

The roots of the moss fern go back to prehistoric times. In fact, some species look like they emerged from a jungle-like painting of dinosaurs. Today the Selaginella – the Latin name of the moss-like plant – often appears as a houseplant.

Moss fern: which species are suitable as house plants?

The moss ferns, also known as moss herbs, can be distinguished from over 800 different species around the world. There are three main types of indoor plants: the Selaginella apoda looks like a ball that has been slightly flattened. It has shorter shoots with light green foliage. A species that is less common is the Selaginella martensii. Their characteristic is the upright growth and the numerous aerial roots. Selaginella kraussiana is known for its longer and creeping shoots. There are both fresh green varieties and those that develop white shoot tips. A very special specimen, which enjoys a rather rarity status, is the Selaginella lepidophylla. The so-called resurrection plant has the ability to curl up when it is dry and, conversely, to unfold again when it is humidified.

Incidentally, the moss fern is often given away on New Year’s Eve. Equipped with talismans, it should bring luck to the recipient.

The right location

Moss herbs are not easy to care for. They need a lot of light, but cannot tolerate direct summer sun. In the flower pot, the moss-like and fern-like plant should also not be too warm or too dry. It is in good hands at a bright west or east window – away from the heating. In winter, the moss fern does not mind the weak solar radiation. The ideal room temperature is fifteen to twenty degrees Celsius. High humidity is important for Selaginella. Tip: Place a bowl filled with gravel and water under the flower pot to avoid waterlogging.

The spherical cactus is a popular houseplant due to its attractive growth habit and its even rows of light thorns. You can find out how to properly care for your ball cactus here.

Ball cactus: beautiful, but thorny

The ball cactus, which is also known as the mother-in-law’s chair, can grow up to five meters in size and one meter in diameter. However, it takes many years and desert-like conditions to reach this level. Its special characteristic are the numerous, long and bright thorns that are neatly lined up next to each other. Only a few species of the ball cactus will flower when kept as houseplant.

Location and care of the houseplant

In order to be able to form its beautiful thorns, the spherical cactus needs a lot of light all year round – preferably through direct sunlight. The soil should contain about two thirds of peat and compost and about one third of sand for ideal conditions. The temperature of the area should be between eighteen and twenty degrees Celsius, in winter around five to ten degrees. At lower temperatures, brown spots can form on the green plant. In summer you should water your ball cactus moderately, in winter you can greatly reduce maintenance without letting the soil dry out completely. As with all cacti, waterlogging must be avoided at all costs so that the roots do not rot.

This is how you can propagate the cactus

If you want to propagate your ball cactus, the best way to do this is by seeds. Growing from small seedlings to large houseplants is not difficult as the cacti grow fairly quickly even with little care. To fertilize your cactus, add some liquid fertilizer to the irrigation water in the growth phase in spring about every two to three weeks. In spring you can repot the plants and provide the new container with fresh substrate. 

The origin of the name is obvious: characteristic of the old man’s head is the white mop of hair on the shoot tips, which makes the cactus a real eye-catcher in every living room. Here you will find important information on caring for this special type of cactus.

Greisenhaupt as garden and houseplant

The desert cactus Greisenhaupt originally comes from the steppes of Mexico and can grow up to fifteen meters in height in nature. With a size of about six meters, the cactus develops flowers outdoors that take on a yellowish-pink color. In addition, it then bears small fruits that are two to three centimeters in diameter. As a houseplant, it is usually between twelve and fifty centimeters tall. His long, snow-white hair is reminiscent of an old man’s head. They protect the plant from the bright sun. In keeping with its appearance, the cactus has a very long lifespan. In his homeland there are said to be species that are a thousand years old.

Caring for the cactus

The best location for the Greisenhaupt is warm and sunny, the ideal temperature is around twenty degrees Celsius. In autumn and winter, the ambient temperature should not drop below eight degrees. The old man’s head is sensitive to drafts, which is why you should not place the plant near a window that is constantly open. In spring and summer you can water the cactus regularly and also spray it with water for maintenance. You should fertilize your old man’s head especially during the growing season, whereby no fertilizer should get onto the hair.

Repot and dust regularly

If your cactus is still young, you should repot it once a year, preferably in spring. Use soil for this, in which you mix some peat and compost and a third of sand. If you want to keep the grayish-white coloring of your hair, you should remove dust from your old man’s head at regular intervals. To do this, you can rinse your hair with lukewarm water for care.
