Venus flytrap cannot grow all year round at room temperature. For normal growth and existence, she needs a resting period of 3-4 months. Otherwise, the plant will not live with you for long. In autumn, it is necessary to start preparing the Venus flytrap for wintering. In October-November, you should gradually lower the temperature, first to 10-15 ° C, and then to about + 5 ° C. Also at this time should gradually reduce daylight hours, from 14-16 hours to about 8-9. To achieve this, you can put the plant on the balcony or on the windowsill near the ajar window. Soon Venus flytrap will grow wide, adjacent to the ground leaves and small traps, which will mean its readiness for winter. Glazed balconies or greenhouses are great for wintering. With a wintering temperature of +10 to + 5 ° C, the Venus flytrap, as before, Needs lighting and watering from a pallet. Water for irrigation should be at the same temperature as the soil. Waterlogging of the substrate should not be allowed. If there is not enough natural light, plants will need to be illuminated with cold lamps. The duration of lighting in winter should be approximately 8-9 hours.
In the event that there is no suitable place for wintering, you can put the plants in the refrigerator for wintering, however, the temperature there should not go beyond 0 to + 5 ° C. Only at this temperature do plants not need lighting and retain their leaves. At minus temperatures, the leaves turn black and die. After preparing for the winter, the Venus flytrap should be sprayed, and then pack the pot in a bag with several ventilation holes and place in the refrigerator. About once a month, the substrate must be watered with distilled water of the same temperature.
It is not recommended to lower the temperature below + 5 ° C, for plants you have not hibernated before.
Plants wintering on balconies or in greenhouses should not be taken out of wintering – with an increase in daylight and temperature, they themselves will leave it. The same plants that hibernated in the refrigerator should be removed after about 3 months, after which they should remove packages from their pots and put in a cool place under the lamps. The duration of lighting at first should be 10 hours a day, and then gradually increase it to 14-16 hours. It is also necessary to smoothly raise the air temperature. Plants that are supposed to be kept under natural light, on balconies or sunny windowsills, should be removed from wintering in early spring.
After wintering, plants need to be transplanted into a new substrate.
You can propagate a Venus flytrap by seeds, dividing bulbs or cuttings.
The easiest way is to divide the plants using daughter bulbs.
In old plants, quite a lot of such bulbs or growth points are formed. They can be separated from the parent plant with a sharp clean blade and planted separately. It is advisable to sprinkle the slice with powdered coal. It is important that the plant to be separated has at least a few roots. It is advisable to divide the plant in this way no more than 1 time in 2-3 years.
To produce seeds, you need to take a healthy plant that has passed at least one wintering with you. Flowers appear in spring or early summer. You can pollinate flowers with a brush, 2 days after they open. After pollination, the flower will wither and a box will form. Seeds can be collected when the box becomes dry and begins to crack.
If you do not plan to get seeds from the plant, it is better to cut the peduncle (especially if the plant has not hibernated yet), because flowering takes away a lot of energy from the Venus flytrap.
Pests and diseases
Aphids can appear in the traps of these plants, which leads to their curvature and deformation. You can fight it with the help of various aerosols against aphids.
With a dry and warm content of the Venus flytrap, it can also be attacked by a spider mite. A means of dealing with it is to spray a plant with anti-tick drugs.
If Venus flytrap is constantly in a too wet and humid environment, a black soot fungus may appear on it. To prevent this, the plants must be kept in the right conditions. The fungus control agent is a suitable fungicide.
Gray rot or botrytis is when rot appears on the plant as a result of a fungal infection, which is then covered with a gray fluff. When it occurs, it is necessary to cut off the damaged parts of the plant, and then treat the entire plant together with the substrate with one of the available systemic fungicides.
A bacterial lesion is when a trap cannot “digest” a captured insect, as a result of which it begins to rot. This process, if not stopped, can go to other parts of the plant and, in the end, destroy the whole plant. In the case of rot, it is necessary to remove the damaged trap in time.
