- Fertilize: once a week
- Propagation: by division or sowing
- Diseases and pests
Worldwide there are about 200 to 300 different types of Schildfarns. He is one of the most species-rich plants. He is also very widespread. Whether in tropical areas or very cool areas - everywhere the Schildfarn can be found. In general, the ferns grow on stony ground, in conventional soil, in crevices or on forest soil. He just does not like the sand very much because he can not offer him the desired water supply. This makes him very undemanding in terms of soil quality. In our latitudes, mainly the Brauns Schildfarn, the lobed Schildfarn and the awn shield fern are known and common. All varieties are protected by nature and may therefore not be excavated or picked in the wild. Who seeks shield fern for the garden, should therefore buy it in a garden center.
But not only in the wild, the ferns grow. He is also known as a houseplant. However, our domestic plants are only partially suitable. Anyone who considers the shield fern as a houseplant in our latitudes will have resorted to tropical species. They are mostly from the Far East and belong to the genus of Shield Ferns, the Weichen Schildfarne and the Kleinwüchsigen shield ferns. All varieties are characterized by a special color scheme and shape and growth height.
Tip: Before the purchase of Schildfarn takes place, especially with the house plants should be carefully considered, which location is provided and what lighting conditions for the fern can be offered. According to the requirements then the purchase should be aligned.
The optimal location
If you want to do something good for your shield fern, you are looking for a place without direct sunlight. Also on a wall or a fence, where he is protected from one side something. Even a partially shaded place is still acceptable. But then more for varieties that have not quite as delicate fronds. In addition, in such a case, the regular casting must be thought of.
Many shield ferns can easily survive the winter outdoors. However, anyone who has brought a more exotic plant should plant it in a bucket so that it can move to a frost-free winter quarters in winter. A temperature of 10 to 12 degrees are completely sufficient in winter quarters. Watering can almost be stopped during this time as the fern takes a break and therefore requires little water and nutrients.
Watering and fertilizing during the summer months
During the summer months, the shield fern should be watered regularly. It is important to ensure that the earth is always kept moist without waterlogging. With a drainage of gravel under the plant can be prevented accordingly.
Shield fern in the garden should be fertilized once a month with liquid fertilizer in a slight concentration. Indoor plants, however, tolerate the fertilizer once a week.
Tip: When fertilizing half of the usual liquid fertilizer is sufficient.
In order to be able to plant shield fern in the garden, a reasonably plant-friendly soil should be present. The fern is best grown in our latitudes in a soil that is humus and nutrient-rich. Here, some mature compost can be mixed underground. In addition, the soil should not be too sandy, because sandy soil keeps the water very bad and the plants are known to need a lot of water.
In addition, care should be taken when selecting the appropriate location that this is somewhat protected from late frost. If the icy saints once again bring cold temperatures, it may be that the fern then gets too much cold and is hindered in its growth.
Shield fern belongs to the plants that can easily be multiplied. Usually, the fern is taken out of the ground in spring. The earth is as well as possible removed from the roots. The exposed roots are carefully pulled apart by hand. Afterwards the fronds and stems can be separated. Both or more parts can then be repotted at different locations or planted in the garden. Before this happens, however, the root ball should be watered properly. And the planting hole not only tolerates drainage, but also neat water.The soil must be pressed properly after insertion, so that the fern can find a firm grip.
Pests and possible diseases
Although the fern is so easy to care for and undemanding, it is not free from diseases and pests. These can affect any plant, no matter how much effort you make with it.
As a rule, the plant suffers whenever it is not properly poured. Brown edges on the leaves indicate dehydration as well as decreased growth. In spring and summer, fertilizer must not be forgotten. It brings nutrients to the plant, making it less susceptible to disease.
As pests, aphids can occasionally occur. However, these can be sprayed quite easily with the garden hose. If they persist, affected fronds can be removed from the shield fern. In case of heavy infestation you have to work with a pesticide.
Otherwise, the Schildfarn is haunted by a few pests and is only partially susceptible to typical plant diseases.
For fast readers:
- shady to partially shaded location
- enough water in the summer months
- in pot or potted plants, a winter roost with a temperature of 10 to 12 degrees can be searched
- The soil should be humus rich and nutrient rich
- Shield fern can be reproduced very well
How many varieties and types of Schildfarn are there?
Around 200 to 300 varieties from all over the world are known worldwide. In our latitudes, however, only a handful of people work because many ferns are not compatible with our climate.
How should be poured?
In the summer months the shield fern needs a lot of water. The root ball must never dry out, but it must also be no waterlogging. For this reason, you should work with a drainage. In the winter months, the water requirement is very low, so that in freestanding plants, the climate provides sufficient water.
Can Schildfarn be propagated?
Yes. The multiplication is even quite simple. By a division, which should take place by a careful pulling apart of the roots, an increase can be made.
