Cobra bottle grass, as the name suggests, is a bottle grass plant with the same shape as Cobra. In foreign countries, cobra bottle grass is a very well-known insectivorous plant variety, which is the collection target of many players. Let's meet this mysterious plant today~
Cultivation method of Cobra bottle grass basic knowledge of Cobra bottle grass: Cobra bottle grass is one of the genera of bottle grass family. It is an insectivorous plant, mainly distributed in Northern California and Oregon. The left and right sides of their bottle caps are glued together to form a spherical top, so that the whole insect catching bottle is almost sealed. There is a concave gap between the spherical bottle cap and the bottle body. There are many white spots on the bottle cap and bottle body due to the lack of chlorophyll. Sunlight can shoot into the insect catching bottle through these white spots. Insects (mostly ants) can enter the insect trap through a slit. Once they enter, they will be confused by these white spots, mistakenly think that the white spots are the outlet, lose their way in the insect trap bottle, and finally fall into the digestive juice and be digested.

Peat, sand, water moss, peat, perlite, coconut shell, etc.
2、 Watering
Soft water shall be used for irrigation, such as rainwater, distilled water, reverse osmosis deionized water, etc. Tap water in some areas contains a lot of minerals (especially calcium salts). These calcium salts will deposit and kill plants. This is because most insectivorous plants have adapted to poor acidic soil, so they are extreme calcium avoidance plants, so they are very sensitive to nutrients in the soil.
3、 Temperature
Cold resistance and heat resistance, especially the root should be kept cold, and there should be a large temperature difference day and night; It can survive between minus 10 and 30 degrees, and 15 to 27 degrees is the most suitable temperature for its growth. I like strong light. When the temperature is not too high, I can accept the sunlight. The top of the plant will show red reticulated lines, which is very beautiful.
4、 Diseases and insect pests
Vulnerable to aphids or mealybugs. Minor hazards should be removed manually, and pesticides should be used as appropriate for major hazards. Isopropanol is an effective insecticide against scale insects. Diazinon is also a broad-spectrum insecticide that most insectivorous plants can tolerate. Malathion and acephate are also suitable for insectivorous plants.
Although pests are a problem, the biggest problem is gray mold. It develops in warm and humid environment and becomes a serious problem in winter. Placing it in a cool and well ventilated environment and removing the diseased branches in time can inhibit the development of gray mold to a certain extent. If it fails, fungicides should be used as appropriate.
