The garden marshmallow is a special hardy specimen with different varieties of more than 200 hibiscus species, but only partially found in Central European gardens. In nursing the garden marshmallows are quite straightforward. But they respond to care errors as sensitive as other plants and are not resistant to diseases or pests. Everything you need to know and what you should know when planting, multiplying, caring and hibernating, you can read in the following in the professional care instructions.

LocationThe garden hibiscus likes a sunny location, where it can still be protected from the blazing midday sun. In half shadow, he gets along just as well. Ideally suited to a location where it receives morning and evening sun, which promotes its growth and especially the flowering. It is important for the time between autumn and spring, that it is placed protected from the wind, so as not to be hit by icy winds.
In addition, it should not be planted too close to waters or plants with very high water requirements. This would provoke the risk of overhydration and possibly cause root rot. Planted as a shrub or hedge, the garden marshmallow is suitable for a location where it should offer a visual protection due to its dense ramification or refreshing with its flower color boring garden areas.
soil qualityMuch of its viability comes from the hibiscus in which it is planted. Accordingly, this should meet its requirements, in order to achieve a healthy growth and a long life.
- Nutrient-rich soil
- Permeable to water
- Loosen soil with sand or perlite if necessary
- pH value: acid below 6.5
The best planting time is possible from early spring, as long as it is a hardy hibiscus specimen. Should ground frost develop again, he will not mind if it takes place only at short notice. If this is not foreseeable, the planting should be postponed until the weather conditions have stabilized and prolonged frost is no longer to be expected.
The garden marshmallow takes longer than other hibiscus species to get used to the soil conditions. Therefore, a relatively early planting is recommended if the garden hibiscus is to thrive in the first summer season already magnificent.
Plants in the gardenAlthough garden marshmallows are fairly undemanding, a professional implantation is needed so that they can spend a long, healthy life. Please note the following details when planting in garden soil:
- Broad-growing hibiscus need at least two meters distance to the plant neighbor
- Before planting, place the plant bale in a water-filled bucket for 24 hours
- Dig the planting hole
- The planting hole must be twice as deep and three times wider than the root ball
- Minimize waterlogging risk by spreading perlite, quartz sand or gravel on the plant floor
- Work in compost in the soil
- Insert root ball into the planting hole
- Pour the lifted soil into the planting hole and secure
- Pour generously
- Keep the soil moist for the first few weeks, but do not over-take it
Plants in the tubAs a container plant, the garden marshmallow is implanted in a similar way to the garden bed. Since the risk of dehydration is higher here, it is advisable to choose a suitably sized bucket with at least twice as much earth volume as the root ball is large. It is recommended to use a high quality substrate instead of earth.
This should be rich in nutrients and potassium rich and may contain low levels of sand, to achieve a loosening and thus improved water permeability.
To prevent waterlogging after heavy downpours or excessive watering, the planter should have a drain hole and placed on a saucer. If water collects here, this can be taken from the saucer.
to waterAs a rule, it also rains enough in Central Europe during the summer months, so that the hibiscus in the garden gets along well with the natural rainfall. Should a long period of drought hit hot temperatures, casting is required. Here may be generous poured, but waterlogging is still to be avoided.
You can optimally reduce the need for casting by distributing a thick layer of bark mulch or, even better, gravel on the surface of the earth near the roots. This keeps the soil moist longer because the heat can not reach the earth directly. In addition, you benefit from the layers of less weeds that are harder to grow in the soil due to the lack of light.
Here, however, you should limit yourself to potting soil and from a height of the young plants of five centimeters, this pikieren. From 15 centimeters, you can bring them outside in a pot and put them in the autumn in a frost-free place to overwinter. From early spring, the young plants are strong enough to be planted in the garden soil.
cuttingsPropagation by cuttings works best if you do this during the summer months. Here's how to do it:
- Select approximately 15 cm long shoot with at least three eyes
- Remove lower leaves
- Immerse the interface in rooting powder
- Insert into a pot with potting soil about five centimeters deep
- If necessary, stabilize with a wooden rod cutting
- Keep the soil evenly moist
- Location: bright without direct sunlight
- Optimum ambient temperature: 20 degrees Celsius
- Root formation: about fourteen days later
- Repot when new leaves form
DiseasesGarden marshmallows are generally considered to be robust plants. Nevertheless, they are not uncommon victims of various diseases, which are mainly caused by care mistakes. A quick recognition of what the plant is missing and a professional reaction usually allow a successful treatment.
root rotThe root rot is usually a result of too much watering. This can be recognized by the hanging branches, which bend easily, and the increasingly yellow leaves. Blooms often fade shortly after the bud opening, if it opens at all. In addition, a musty smell above the earth layer to perceive.
If the plant is still relatively handy, you can counter the root rot as follows:
- Dig up the root
- Trim root strands all by at least one third
- Trim roots infested with mold by at least half way
- Put root on absorbent material such as newsprint
- Allow to dry for at least three days
- Enlarge the planting hole by one third
- Mix dry soil with nutrient rich substrate or compost
- Cover the plant hole with the soil all around
- Insert hibiscus again
- Close earth hole with the rest of the earth
- Just pour lightly
- Allow the soil to dry slightly in the next few weeks before watering
This disease shows up with yellowish-colored leaves, which are caused by a lack of nutrients. This is usually due to a poorly selected location with too little light or the plant is exposed to cold winds. Here, a change to a more suitable location and fertilization with many nutrients helps. The yellow leaves fall off by themselves and the plant recovers quickly.
pestsPests such as aphids and spider mites like to make their way through garden marshmallows. Here fast action is required, if only because not adjacent plants are attacked and the pests spread throughout the garden.
aphidsTypical signs of aphid attack are:
- crippled or rolled up leaves
- Buds fall off
- A sticky coating, the honeydew, which is mainly found on the stems, but also on the undersides of the leaves
To do this, place your thumb and forefinger on the branch or stalk, press them together slightly and then pull your fingers upwards. In this way they collect aphids. In order to reach everyone, further treatment is necessary. Nettle broth is environmentally friendly and very effective in effect:
- Collect two hands full of fresh nettles
- Immerse in a bucket with two liters of cold water
- Let it rest for about twelve hours
- Sift out nettles
- Pour the broth into a squeeze bottle
- Daily spray the garden fish from top to bottom with it
- After one week, no aphids should be present
spider mitesSpider mites love the dryness and leave on their hosts spiderweb-like webs and bright spots on the leaves. Depending on the species and temperature, the color of spider mites can vary between pale green, reddish brown, yellowish green and orange. They are difficult to see with the naked eye. A little trick helps quickly to get a grip on spider mites in an uncomplicated way:
- Shower off Hibiscus vigorously
- Wind translucent plastic wrap as far as possible airtight
- Remove the foil after four days
- Shower again vigorously
- If necessary, the film coating can be repeated a second time
Varieties / speciesSome of the best-known hibiscus varieties that can hibernate outside include
- Hibiscus syriacus - Syrian garden
- Hibiscus trionum - flower of the hour
- Hibiscus arnottianus - garden shrub marshmallow (frost hardy)
The garden marshmallow is a wonderful specimen that brings color to any garden. With a low maintenance and a robust constitution, illnesses can hardly harm him, which are usually due to care mistakes. He can easily reproduce and has no above-average claims in any other area. So a perfect garden plant for every home gardener and anyone who wants to avoid a lot of gardening, but do not want to miss pretty seas of flowers.
