Schefflera ∗ The 10 best care tips and varieties (Radiant Aralia)

origin

The genus of plants Schefflera comes from tropical and subtropical Asia and Australia. Depending on the species, the areas of origin are still a bit limited - the most important species for the local indoor culture, the Schefflera arboricola, is particularly common in Taiwan. From there it has very low maintenance requirements - it is therefore ideal as a houseplant for beginners.

Houseplant

As a beginner's houseplant, the Schefflera is primarily predestined because it is a tropical plant all you need consistently warm temperatures - and you can do that automatically in a heated room Offer. Due to its tall, slender growth with fewer branches, it also does not take up much space and yet, thanks to its broadly fingered, nicely variegated leaves, it is an attractive and beautiful sight Volume.

leaves

From an ornamental horticultural point of view, the leaves are the most important thing in the ray aralia. With their wide fingered arrangement and the light green to cream colored variegation With a dark green background, they can look great in groups of houseplants on the windowsill Set structural accents. The single leaves of the alternately attached finger arrangements are oval to obovate, evergreen and mostly with entire margins, in some species they are also sawn.

blossom

The flower plays a rather subordinate role in the room culture in the case of radiation aralia - on the one hand, because it is not necessarily particularly spectacular. Above all, however, because a specimen kept in the room rarely produces them. So you can count yourself lucky if your Schefflera brings you one - this is especially possible with an older plant.

The flowers of a Schefflera are cluster-like umbels in a greenish to yellowish tone with small, hairy bracts. Their fine flaky appearance creates a nice contrast to the smooth, dark foliage. In the wild, the flowering period lasts from July to October, in indoor cultivation only until August.

The flower characteristics at a glance:

Schefflera in indoor culture rarely produces them
grape-like umbels of inconspicuous color with fine, downy bract hair
Flowering period around July to August

fruit

The fruits that form after blooming are also very attractive: the mustard-yellow to Orange-red, small berries on the dark flower stalks create a nice splash of color in the Foliage.

Which location is suitable?

Like so many tropical plants, the Schefflera needs a relatively bright, but not full sun location. But it can also thrive quite well in a darker corner. In summer you can put it outside for a while - but it shouldn't be exposed to temperatures below 10 ° C. In general, it can be kept in a heated room all year round, because it can also cope well with dry air. What she likes less, however, is drafts.

Pour Schefflera

The water requirement of the ray aralia is moderate. Only water when the substrate has become completely dry again after the last watering. If the bale is permanently wet, there is a risk of root rot. The Schefflera is also ideal for the comfortable Hydroponics with soilless substrate Expanded clay,(€ 16.36 at Amazon *) which you put in a water-nutrient solution in the planter. Then you don't need to water at all.

Cut Schefflera properly

The Schefflera arboricola grows into a stately tree in the wild. Of course, that doesn't work in the room. A regular shape cut is therefore essential, especially since the ray aralia is very vigorous. Basically, like other woody plants, it can also be cut. Too long shoots can best be removed directly over a fork of a branch. Even after a lot of leaf loss after wintering, a cut has a rejuvenating effect with vital new shoots.

Shorten

In order to keep the height in check and at the same time to promote a compact, shrubby growth, the side and main shoots should be trimmed regularly. It is best to shorten it in early spring.

bonsai

Due to its rapid growth, the Schefflera is also well suited for bonsai culture. However, the design freedom is limited - because the branches of the ray aralia break relatively easily, so that wiring can only be done with great care. What you can experiment with a lot, however, is the design by cutting back. If you behead a young specimen at the top when you buy it and regularly prune back over the newly emerging buds, the result is an umbrella-like crown.

It is even possible to modify the leaves by regular shape cutting and give them an artistic look.

To note:

Schefflera is well suited for bonsai culture due to its fast growth
Deformation, however, if possible only by cutting and not by wire
Sheets can also be individually shaped by cutting

Repot

You should repot a young Schefflera relatively often, about once a year. It has a rejuvenating and vitalizing effect on the plant if you shorten its roots a little. If you discover rotten areas, you can remove them at the same time before you put the Schefflera in a new, slightly larger pot.

Yellow leaves

If the leaves of your Schefflera turn yellow, it could be different green. The most likely are:

too wet substrate / root rot
too sunny / too dark location

Root rot?
If you have watered the Schefflera too much and left it too wet, the roots may have rotten. Take the plant out of the pot and check the root ball for rotten spots. If they are still isolated, you can remove them and put the bale in fresh soil - in the worst case scenario

Wrong location?
If there is too much direct sunlight or in a corner that is too dark, the Schefflera can also react with yellow leaves. Try a different location with moderate lighting conditions.

Brown leaves

Brown leaves mostly indicate drought. Possible causes for this are:

not enough water
too much direct sunlight and heat
sudden temperature change from warm to cold

Lack of water?
Although the Schefflera does not need a lot of water compared to some other tropical plants, too little is of course not good either. Check the root ball for dehydration and water regularly from now on.

Sun exposure and heat?
Brown leaves can also simply be sunburn. Keep your Schefflera out of direct sunlight and strong heat.

Temperature change?
If you want to put the Schefflera outside in summer, you can do so as long as it is not much cooler outside than in the heated room. A too violent temperature change from warm to cold can be acknowledged by the Schefflera with brown leaves.

Loses leaves

If the leaves of the Schefflera change color, it usually sheds them after a while. If she loses a lot of sheets without color notice, it can indicate the following:

too dark and too cold location
abrupt change in light due to change of location
too wet substrate

Too dark and too cold?
If the Schefflera is too dark, it can shed its leaves. It shouldn't be too cold either - in summer your ambient temperature should not fall below 18 ° C, in winter 10 ° C.

Abrupt change in light?
If you move your Schefflera to a different location, for example in winter, this can also affect it. Don't expect the light to change too much - it's best to just leave it in a window seat all year round.

Too wet?
When the leaves are shed, too wet a substrate and root rot can be the trigger. Replacing the top layer of soil and removing any rotten roots can be helpful here.

Diseases

Fortunately, the Schefflera is quite robust against diseases. Actually, it only shows unhealthy reactions to certain care errors - such as yellow and sloping ones Leaves if there is too much water and root rot or if there is a lack of light, brown and burnt leaves if it is dry and Heat. However, these maintenance errors can usually be corrected easily.

Pests

Pests, on the other hand, are occasionally an issue. Sometimes the Schefflera can be attacked by the following pests:

Mealybug
Spider mites
Scale insects
Thrispen

Mealybug
You can easily recognize the mealybugs by the typically woolly webs on the leaves. Mealybugs are best sprayed with a mixture of water, a little alcohol and a little curd soap.

Spider mites
Spider mites They also reveal themselves clearly, through thread-like webs. It is best to rinse them off with water first and then wrap the plant under foil. The mites cannot tolerate moist air and also suffocate under the foil seal.

Scale insects
Scale insects can attack almost any houseplant once. They prefer to settle on the twigs and shoots, the stems and the undersides of the leaves. If the infestation is still weak (check regularly!), The parasites can simply be wiped off with a damp cloth. If the infestation is more severe, spraying with a water and nettle broth or an oily preparation is suitable.

Thrispen
These partly winged insects feel particularly comfortable in dry heat. So there is an increased risk, especially in summer, that they will infect your ray aralea. They can best be combated in a similar way to scale insects: first shower with water and with More stubborn infestation can be treated with a water-nettle broth or water-tansy broth Body. Preparations based on neem tree oil have also proven effective.

Multiply Schefflera

Radiated aralia can be propagated relatively easily by cuttings. To do this, you cut a not yet lignified shoot and simply let it take root in a glass of water. You can also sow a Schefflera. At a warm soil temperature of 18-20 ° C, a seed germinates after about 2 to 3 weeks. A warm, even growing climate under foil is also recommended.

Cuttings

In addition to the water glass, you can also put the cuttings in Potting soil let root. A floor temperature of around 18 ° C should be guaranteed. You also have to keep the substrate evenly moist, of course.

Toxic to cats

Radiation aralia are quite slightly poisonous - they contain oxalate crystals in all parts of the plant, which are only harmful if taken in larger quantities. Skin contact with the leaves is usually not critical, but it can also lead to slight irritation. Oral intake, on the other hand, is not to be taken lightly, especially in cats, who are known to like to develop an intimate relationship with indoor plants.

The problem is that cats cannot break down the oxalic crystals in the intestine and only partially excrete them. However, this can lead to the formation of kidney stones, damage the bladder and trigger arthritis. If you have a cat in the house, you should rather refrain from a ray aralia as a new roommate.

eat

It is of course anything but advisable for humans to nibble on the pretty leaves of the ray aralia. Of course, this is especially true for small children, in whom even small amounts of ingested oxalate can make themselves felt - through irritation of the mucous membranes, vomiting and diarrhea. If small children live in the household, keep a radiation aralia only at a height that is inaccessible for the juniors.

sorts

In the case of the Schefflera arboricola varieties, a distinction can first be made between the green and the variegated. Which of these two groups you tend to belong to is, on the one hand, a matter of taste. On the other hand, the associated varieties each have slightly different location requirements.

Green varieties
The pure green varieties generally need less light than the light variegated ones. They are therefore also suitable for a less light-flooded corner of a room that needs to be filled with attractively structured foliage.

Schefflera Compacta

This variety has dark, lush green finger leaves and, according to its name, compact growth. This makes it particularly suitable for bonsai culture. In the room it is about 1.30 to 1.50 m high. Like all green rays, it gets by with relatively little light.

Schefflera Amate

The Schefflera Amate is notable for its large, dark green and very shiny leaves. It tolerates a partially shaded location well and is generally easy to care for - also an ideal office plant. Overall, it will be almost as high as the Schefflera Compacta.

Variegated varieties
With variegation, the Schefflera's finger leaves naturally exude a special color and structure aesthetic and can be a real eye-catcher in the room. The variegated varieties have to be a bit lighter, but are otherwise not very maintenance-intensive.

Schefflera Gold Capella

As its name suggests, the variegation of this variety is yellowish-golden, which gives it a special charm. It is also one of the classics among room items and can often be found in offices. The variegation can vary considerably within the foliage, as it only spreads over a wider area with larger leaves. The young shoots create a fine, dark green contrast. The Schefflera Gold Capella needs a relatively bright location, but like all other types of radiation it must be protected from direct sunlight.

Schefflera Renate

This variety, like the Schefflera Diane, is characterized by the leaves that are slit at the tips. This gives the foliage a further structural accent in addition to the light variegation. The Schefflera Renate should also be relatively light, otherwise it is easy to care for and only needs moderate watering.
