Description of Green Orchid
Green orchids look exotic. Such flowers grow well flat on the window. Green orchid is a representative of different varieties of plants, each of which has its own external features.
Orchids of the phalaenopsis and cymbidium species are green. The color, size, number of buds, the length of the peduncle depend on the type of plant.
Such varieties of orchids are distinguished:
- Phalaenopsis Amalfi. Its petals have a yellow-green hue, a purple lip. The flowers are large; from one high erect peduncle, 4 to 7 buds are formed.
- Phalaenopsis Violacea alba. The flowers are small in size. At the base, the petals are purple, but then turn into a light green color. Buds develop on thin creeping shoots. Flower-bearing arrows are produced in an amount from 1 to 10, 1-6 buds develop on each.
- Cymbidium Sessa Green Beauty. The flowers are large, with bright green petals and a yellow lip with purple or red spots. Strong shoots, upright. On one high peduncle, 5-20 buds develop. The leaves of Cymbidium are long and pointed.
Green phalaenopsis varieties also include Cattleya Bowring, Luteous Forb, Venus Shoe, Sunrise Goldmour. Their flowers have muted, soft shades.
The green orchid is unpretentious to external conditions, well takes root in apartments. For her, you need to choose a place with good lighting.
Orchids have aerial roots, in the wild they do not grow in the ground, but attach to other plants. Garden stores sell special transparent plastic pots for orchids. They have a small volume and many drainage holes at the bottom.
The substrate for orchids is chopped and processed with nutrients wood and coconut fiber. The substrate must be bought at flower shops.
Seeds of green orchids must be bought from trusted manufacturers so as not to fall for low-quality goods.
Seeds before sterilization in the substrate are sterilized with bleach. The liquid is poured into a small container, the seeds are thrown there, shaken well and left for 10 minutes. Seeds are not germinated in the soil, but in a special water mixture. To prepare it, prepare:
- 1 liter of distilled water;
- 8 g of agar-agar;
- 10 g of glucose and fructose;
- 1.5 g of nitrogen-phosphate-potassium fertilizers;
- root-forming stimulant;
- litmus test.
0.5 l of water is boiled, added to non-glucose, fructose and agar. The mixture is stirred until the components are completely dissolved. The second 0.5 l of water also needs to be boiled, removed from the fire, add 5 drops of stimulant and fertilizer. The pH of the mixture should be 4.2-5.2: in a more acidic or alkaline environment, the seeds will not germinate.
The liquid is poured into sterilized glass jars with a narrow neck, about 30 ml each. Then the jars are corked with cotton and gauze and sterilized in a water bath. The material is left for 5 days. If mold appears inside the containers, orchid seeds cannot be placed there. Then seeds are put in jars with the mixture.
Under normal conditions, the seeds germinate during the year. Then the young seedlings are removed from the liquid, washed with water and planted in the prepared sterilized substrate.
Planting Green Orchid Seeds
Phalaenopsis orchids are propagated by processes. A young shoot is important to properly separate from an adult plant. The process is cut off with secateurs or sharp scissors treated with alcohol. Place the cuts sprinkled with charcoal.
The roots on the process grow even before separation from the mother plant. To do this, it is wrapped in wet moss. Moss requires constant moisture and lighting. The plant is moved to a warmer place.
When the shoot has roots, they plant in a pot:
- Sterilized drainage stones (expanded clay, pebbles) are laid at the bottom of the pot.
- The process is placed in the center of the pot, the root neck is placed at the edge of the container. The roots are evenly distributed throughout the container.
- Soil is poured into the pot in layers, supporting the process with a hand.
The planted shoot is watered first in 2-3 days. Subsequent watering is carried out after the soil has dried, after 5-6 days.
A full-fledged plant from the process is formed for 2-3 years. In this case, follow the rules of care.
For normal growth and regular flowering provide optimal conditions:
- temperature during the day - 18-20 ° C, at night - about 15 ° C;
- bright diffused lighting, protection against direct ultraviolet rays, shading at noon;
- moderate watering with filtered water at a temperature of 25 ° C;
- spraying flower leaves with special top dressing.
Feeding is prohibited during dormancy and flowering. The plant is transplanted as it grows (about once every 2 years). Orchid requires an urgent transplant for diseases of the roots and damage to the substrate.
Diseases and Pests
Improper care will lead to plant disease. Common Orchid Diseases:
- burns from direct exposure to ultraviolet radiation;
- wilting and leaf fall due to overheating or hypothermia within 10 hours;
- drying of the roots due to low humidity, rotten roots and leaves due to high humidity;
- cessation of flowering due to lack or excess of fertilizer.
Problems are most easily prevented by properly caring for the flower. Damaged parts of the plant are removed. The diseased plant is placed in a shaded place, they begin to water moderately, adding sugar to the water every other time. If the root system is damaged, new roots grow and the flower is transplanted.
Improper care reduces the immunity of the plant, it becomes vulnerable to pests. Orchids most often attack whiteflies, spider mites, aphids, mealy worms, scale insects. Insecticides help get rid of them.
Green orchids need the right light and moderate humidity. Sterility during planting and proper care are the main measures for the prevention of diseases and the key to regular and rich flowering.
