Carnivorous indoor plants: useful tips for growing carnivorous plants to keep at home.
Thecarnivorous indoor plantsthey are characterized by modest dimensions and have needs compatible with the typical habitat of the home environment. It is important to point out that manycarnivorous plantstherefore, they need high levels of humidity to be able to do themgrow indoorsit is necessary to set up a terrarium.
Cultivating carnivorous plants: insectivorous plants
There are 600 species ofcarnivorous plants very different from each other: they belong to 7 families and 15 different genera.
All the carnivorous plants they have a peculiarity that unites them: in their evolution they have developed special systems to capture and digest insects. For this characteristic carnivorous plants are often calledinsectivorous plants.
The most evolved carnivorous plants have developed hunting systemsactive while others wait for theinsectsthey pose forcapture them. From the captured insects, these plants can obtain the metabolites necessary to meet their energy needs.
The first treatise oncarnivorous plantsit is due to Charles Darwin who in 1875 dedicated a book entitled “Insectivorous plants”.
How do carnivorous plants catch prey?
Precisely on the basis of the method of capturing insects you can have a general classification ofcarnivorous plants.
Some carnivorous plants capture insects through "sticky" secretions: once the insect settles, it will no longer be able to escape by "glued" to the plant which will immediately digest it.
Therecarnivorous plantAbhishek, as well as other common plants, have specialized funnel-shaped leaves which, at the bottom, contain a pool of digestive enzymes: when the insect slips inside, it's done for!
The Dioneae is onecarnivorous plantmuch appreciated (pictured above). This plant, like other insectivores, catch prey with jerky movements of the leaves.
They are not missingcarnivorous plantswith suction traps: the prey is literally sucked into a bladder in which a pressure vacuum is generated.
Some plants have hair and eyelashes that direct the insect directly into the digestive organ.
Carnivorous indoor plants
Betweencarnivorous indoor plantsthe most suitable species are:
- Drosera capensis
- Dionaea muscipula
- Sarracenia purpurea
These are very demanding plants, therefore not easy tocultivate(neither at home, nor in the garden). You can decide to try your hand at cultivation of carnivorous plantsonly if you have enough time to devote tocare.
In the article "Dionea, plant and care", you will find all the information forcultivatethis particularcarnivorous plant. The snap leaf of the Dionea is shown in the photo below. Betweencarnivorous plants, the dionea muscipula is undoubtedly the most widespread: it has very ornamental specialized leaves.
The appearance of this plant changes a lot according to the season: in winter, the leaves drop and become crawling on the ground. The plant enters a dormant period when temperatures drop. In summer, however, the leaves appear erect.
Grow carnivorous plants indoors
During the winter, thecarnivorous plantsthey need little care: they must be kept in a humid environment and irrigated on a weekly basis. Care must be taken to eliminate dead leaves and maintain a constant degree of humidity without allowing the development of mold.
In spring and summer, the plants should be placed in a partially shaded but well-lit area, away from direct sunlight. In summer, watering should be more frequent because the soil must be kept constantly moist.
Drosera capensis, carnivorous plant
Drosera capensis is onecarnivorous plant very popular and also more suitable for growing at home. It is widespread in the humid environments of tropical and temperate areas.
Drosera passively catches insects which, when they land on it, remain glued! The plant has developed glandular cells that produce a sticky liquid! When an insect lands, it will no longer be able to escape thanks to the material secreted by the plant, the carnivorous plant will then slowly incorporate the insect and provide for its digestion.
Dionea muscipula, carnivorous plant
Dionaea muscipula is a plant that does not exceed 10 cm in height. The insect hunt it performs is slightly more active: it has leaves with a toothed margin capable of capturing insects. The leaves contain 3/4 sensitive and colored bristles that act as bait: they attract insects which, by settling, request the leaf by trapping the prey.
Serracenia, carnivorous plant
Serracenia purpurea is thecarnivorous houseplanteasier tocultivatebecause it is the one that best suits domestic conditions. It is also very ornamental. It attracts insects thanks to a "narcotic" nectar. The nectar stuns the insects that fall directly into the funnel of the plant, the area dedicated to "digestion".
Serracenia purpurea is an evergreen herbaceous carnivorous plant, it is native to North America and does not have a stem because its structure is specialized for the passive capture of insects.
Nepenthes, carnivorous plant
Like Serracenia purpurea, Nepenthes also originates from North America and shares insect capture mechanisms with Serracenia.
How to start growing carnivorous plants
It is possible to start the cultivation of carnivorous plants starting from the seed or buying already developed plants in the nursery. Anyone wishing to carry out a first experiment can rely on already formulated soil mix.
The soil, as well as humidity, are essential for carnivorous plants. The soil, in fact, must retain water without getting soaked. The loam forcarnivorous plantsit must be composed of acid peat (blond peat) mixed with perlite or quartz sand, in equal ratio (one part of peat for each part of perlite).
Where to buy carnivorous plants?
In the most well-stocked nurseries or by taking advantage of online sales. On Amazon, an assortment of 5 carnivorous plants in good health can be bought at a price of 39.98 euros with shipping costs included in the price. About 7.99 euros per plant. For all information on the offer mentioned, I refer you to the Amazon page of the "German nursery Exotenherz".
Please note: Our website has no connection with the seller. We reported this offer because we bought the plants ourselves and they arrived in excellent health.
For repotting you can buy specially formulated soil, also in this case we recommend a product to "this Amazon page". The mud peat allows a gradual release of moisture while the perlite will prevent you from root rot.
At the time ofrepotting, remove the soil not attached to the roots by replacing it with fresh soil.
How to care for carnivorous plants
To irrigate carnivorous plants, you will need to use osmosis water, distilled water (even the water from the conditioner is fine) or rain water. Tap water should be avoided like the plague! Contains limestone which will tend to increase the pH of the soil and damage the leaves.
For thecareof thecarnivorous plantsyou must ensure:
- A high humidity
- The right soil
- Avoid water stagnation
- Absolutely avoid using universal soil, garden soil or soil for succulents
- Avoid the use of fertilizer
- Avoid feeding dead insects
- Avoid giving too many insects
- Place the plants in a very bright display
- If the plant is weak, sacrifice flowering by cutting it off
