Dionaea - Droseraceae - How to care for and grow dionaea plants
HOW TO GROW AND CARE FOR OUR PLANTS
There Dionea it is not a particularly suitable plant for beginners in cultivation as it requires quite extreme conditions and must be grown strictly outdoors.
Species: Dionaea muscipula
The genre Dionaea includes only one species, the Dionaea muscipula,insectivorous perennial plant native to the swampy areas of North and South Caroline (America) commonly known with venus or flytrap.
These are so-called insectivorous plants (or carnivorous as they are often called) characterized by the fact that the leaves are formed by an enlargement of the petiole which opens up to form two valves with the margins covered by about twenty setolerigid and with numerous hairs. When an insect attracted by the nectar secreted by the plant leans on these leaves, the hairs perceive its presence and snap like a spring, trapping it. Once captured, the insect will be digested by particular enzymes secreted by the plant to obtain all the nutrients useful for its nutrition. The leaves will remain closed for the entire duration of digestion and will only open when this is finished (from ten days to a month).
They are very difficult plants to breed.
There Dionaea it must be strictly raised outdoors and in full sun (never keep it flat, it would die in a short time). Only from November until mid-February can it be kept out of direct sunlight.
The cultivation temperature during the winter period must be between 5 ° C and 10 ° C while it obviously has no problems with the maximum temperature since it must be grown in full sun.
They are habitual plants therefore they should not be moved from the place where they grow well.
The first fundamental aspect for the cultivation of dionea is to use water strictly poor in mineral salts therefore either clean rainwater or demineralized water.
To water it, you must never pour water from above but you must keep it in the pot so that the plant absorbs it by capillarity and the earth always remains soaked (they are plants native to marshy areas). From November to February, the period in which the plant enters vegetative rest, the water must be removed from the sub-pot, keeping only the soil moist. From mid-February the water is put back under the vat.
TYPE OF SOIL - REPOT
There Dionaea it is repotted every year in mid-February using acidic sphagnum peat not added with fertilizers that is added to the moistened pot without any compression. Make a hole with a pencil and place the dionea in the hole created so that the white part remains buried, then gently approaching the soil around the plant.
They are plants that should NEVER be fertilized.
The white flowers are formed at the top of a long flower stem which, however, it is advisable to cut as soon as it begins to form because of no ornamental value: it is not necessary to waste so much precious nourishment to the plant.
The multiplication of the Dionaea it takes place by division of the plant at the moment of re-potting, taking the small seedlings that form at the base of the mother plant. In this way, plants of good size are obtained already after the first year.
PARASITES AND DISEASES
The leaves are burned
Burnt leaves form when you place the plant from a little sunny position to a very sunny one. There is no need to be alarmed, it is normal for this to happen.
The leaves are black
If the old leaves turn black, don't worry: this is normal. If the young leaves turn black instead, then it is necessary to analyze all the cultivation technique followed up to that moment because something is wrong.
Presence of small whitish animals on the plant
Deformed leaves indicate the presence of aphids or as they are commonly called lice.
To combat them, it is advisable to completely immerse the plant under water for a few hours until the aphids come to the surface.
One realizes if the Dionaea it is in good health if, by pressing the leaves, they snap shut. However, it must not be a game as it is unstress for the plant.
If you want to give nourishment to the plant, remember that it accepts only live animals and only small invertebrates such as flies, wasps, spiders, ants. Nothing else.
