Epiphyllum ∗ The 10 best care tips (leaf cacti)

Origin and Distribution

Most species of the genus Epiphyllum are native to Central and South America and the Caribbean, where they grow as epiphytes on the tall trees of the tropical, humid rainforests. Above all, hybrids of wild species that look very similar to one another can be found in the trade. These are considered less demanding than their parent species and are therefore easier to care for as indoor plants.

use

Due to their tropical origin, Epiphyllum leaf cacti are not hardy here and are therefore primarily cultivated as indoor plants. The plants, which are very sensitive to the cold, may only be used on the terrace or balcony during the warm summer months, but should not be exposed to the blazing sun there. Most species and varieties have a pendulous habit, so you can keep them as a hanging plant. If this is not desired, the long shoots should either be supported or tied upwards.

Appearance and stature

All Epiphyllum leaf cacti grow either epiphytically or lithophytically, i. H. as epiphytes on trees or rocks. The different species grow shrub-like, developing either hanging or climbing and only rarely upright shoots. The long shoots are often heavily branched and lignify with age. In contrast to the round older ones, young shoots are rather flat and are not dissimilar to leaves - however, despite all the external similarity, they are not deciduous leaves. Thorns are usually absent. Some species develop some, but these only remain very small.

Blossoms and flowering period

The solitary, mostly funnel-shaped flowers can become very long: some Epiphyllum species impress with flowers up to 30 centimeters in size, which are also colored in almost all colors except blue can. The wild species mostly have white, yellow or pink flowers on the outside, which are pale yellow or whitish on the inside. The flowering times differ greatly depending on the species and variety. Incidentally, many species only bloom from an age of approx. five years, which is why a lack of flowering does not necessarily have to be attributed to inadequate care.

fruit

In this country, due to the lack of pollinators, fruits are seldom formed. However, you can buy the black, kidney-shaped seeds in specialist shops and use them to grow your own plants.

Which location is suitable?

Epiphyllum leaf cacti prefer a bright and warm location that is not exposed to strong sunlight. A partially shaded place is best, which offers protection from the scorching sun, especially around midday. If the location is too sunny for the plant, this can quickly be seen in leaf burns. In summer you can put the leaf cacti outside, but you should also protect them from the midday sun and rain. When it comes to housing, a high level of humidity between 60 and 80 percent is also important.

Substrate

Even if epiphylenes are cacti, the one that is commercially available Cactus soil unsuitable as a substrate. Leaf cacti have a high nutritional requirement that cannot be met by cactus soil. Instead, use special soil for leaf cacti (available from specialist retailers) or mix them with normal ones Potting soil and a third of bark mulch, pumice gravel or Quartz sand(€ 14.90 at Amazon *) yourself - it is important that the substrate is well permeable and that waterlogging cannot arise in the first place.

Planting and repotting

Most Epiphyllum leaf cacti grow hanging, which makes them good for hanging baskets. Alternatively, you can plant them in a tall planter so that the long shoots can hang down. Species that are taller than 20 centimeters should either be cultivated as an ampelous plant or supported in any case. When planting, it is not only important to have the right substrate, but also to have good pot drainage. Leaf cacti need a lot of water, but they shouldn't stand wet. The plants therefore thrive best in planters with an automatic Irrigation system.(€ 50.95 at Amazon *)

Since young plants often grow strongly, you should move them to a larger pot every year. In addition, the substrate is used up after three years at the latest and should then be replaced. The best time to repot is spring.

Pour epiphyllum

Even if the classic cacti prefer it dry: As a typical rainforest inhabitant, the epiphyllus leaf cactus needs moisture and does not cope well with drought. The plant does not like dried out substrate, as does waterlogging, by the way. Therefore, keep the soil evenly moist, but not wet, during the growing season. Remove excess irrigation water as soon as possible and use rainwater or decalcified tap water if possible - leaf cacti do not tolerate calcareous water. It is also important to observe these special instructions when pouring:

• Water very sparingly for four to six weeks after the flowering period
• from April slowly increase the watering quantities
• Water abundantly between May and September
• The substrate should then be well moistened
• Spray the plant daily during the growing season
• Do not spray the flowers, they will be blotchy

Fertilize Epiphyllum properly

With regard to fertilization, there are also some special features to consider. Leaf cacti have a very high nutritional requirement, which is why you should never provide them with cactus fertilizer - this is not adapted to the needs of the Epiphyllum species. Instead, take a normal houseplant fertilizer, which you give in half a dose every 14 days between April and September. But be careful: highly nitrogenous fertilizers quickly lead to over-fertilization, which is why whole and blue grain products are not suitable. It is better to use a low-nitrogen fertilizer, as this promotes lush flowering better. There is no fertilization during the winter months.

Cut the epiphyllum correctly

Epiphyllum leaf cacti are very compatible with pruning, but should only be pruned when actually needed - for example because they have become too big for their location. The plants develop a more or less symmetrical growth on their own, which can become uneven if a pair of scissors is incorrectly positioned. Only sick, dead or broken shoots and dead flowers should be removed. Cut this off just below the flower head.

Propagate Epiphyllum

Epiphyllum leaf cacti can be easily cutted or through sowing to propagate, whereby you have to be patient with the seed propagation: Depending on the type and variety, the germination time is several weeks to even months.

Propagation via cuttings

For the propagation of cuttings, cut approx. 15 centimeter long, healthy shoots, the interfaces of which must dry for one to three days before planting. Then put this about three centimeters deep in with Growing substrate(€ 12.99 at Amazon *) planter filled with unfertilized coconut soil and keep it slightly moist for the coming weeks. As a rule, most leaf cacti can be rooted quite easily and show their first growth after just a few weeks.

sowing

You can obtain the seeds for sowing either from specialist retailers or by collecting the ripe fruits from your leaf cacti. The ideal time for sowing is spring. Sow the black seeds on unfertilized coconut soil, coconut gum or special coir pellets and in no case cover them with substrate - all species are Light germs. It is best to place the planter in an indoor greenhouse or cover it with translucent film. Glass. Keep the substrate moist by spraying it with low-lime water.

Overwinter

For the Epiphyllum leaf cacti to bloom abundantly, it is important that the plants rest in winter Stand a little cooler at ten to a maximum of 15 degrees Celsius and also only poured a little and no longer fertilized will. Nevertheless, a lot of light is required, which is why the leaf cacti should be as bright as possible even in winter. A permanently warm overwintering is harmful to the plants, as it weakens them and makes them more susceptible to pathogens and pests.

Diseases and pests

With proper care, Epiphyllum leaf cacti are insensitive, robust houseplants that are rarely afflicted by diseases. If the plants are still ailing, the cause is mostly to be found in incorrect care:

• Rot on shoots and roots: too much moisture
• wilted, thin shoots: dryness
• light, whitish-green spots on the leaf limbs: virus infection
• cork-like stains: fungal infection

With all signs, the only thing that helps is to cut back the diseased parts of the plant generously and to transfer them to fresh substrate and a new pot. Pests are the most common Spider mites as well as mealybugs and scale insects.

Species and varieties

Epiphyllum are an epiphytic plant genus from the cactus family (bot. Cactaceae), which, due to their shrubby growth, are counted among the leaf cacti together with species of various cactus genera. This also includes, for example, the Christmas cactus as well as the Easter cactuswhich, however, belong to other genera and are only distantly related. There are around 17 different Epiphyllum species, with mainly special hybrid forms being cultivated. These are considered to be less complicated and also often form large, fragrant flowers several times a year.

The following species and cultivars are particularly recommended:

• Epiphyllum ackermannii: particularly floriferous species with light red to red flowers up to 12 centimeters in size
• Epiphyllum anguliger: flowers up to 18 centimeters in size, white inside and yellow outside
• Epiphyllum hookeri: species from South America with two-colored flowers that are white inside and yellowish-brown outside, flowers have an intense scent Lilies and only open at night
• Epiphyllum oxypetalum: pointed, small flowers with red outer leaves
• 'German Empress': profuse flowering hybrid variety with numerous bright pink flowers
• 'Spring splendor': pleasantly fragrant, narrow flowers with purple petals
• 'Heavenly Eye': very large, up to 17 centimeters large flowers in bright carmine red
• 'Knebels Dickchen': strong carmine-red flowers with orange-red petals
• 'Queen Ann': forms very large, pure white flowers with a diameter of up to 20 centimeters
• 'Siegfried': many pleasantly fragrant, pale pink flowers with yellow petals
