How to raise an orchid, how to raise an orchid How to maintain an orchid

Jianlan, during the growth period of the light of the feet, avoid strong shade, summer and autumn appropriate shade, winter light. It likes moisture and avoids water, and can tolerate drought for up to 15 days. For the breathability of the planting material, I recommend using humus for cultivation to mimic the mountain environment.

1. Temperature: The temperature in winter shall not be lower than 3°, otherwise it will be frost damaged. It grows vigorously and bears fruit between 20° and 28°, and under the condition of suitable temperature and humidity, most varieties can bloom twice a year, and some of the varieties known as the four-season orchid can bloom four times, and are not resistant to high temperatures above 32°, frostbite below 0°, and the plants are black and die.

2. Humidity: Jianlan likes humidity but is afraid of waterlogging, so the cultivation environment needs to be sprayed frequently to increase humidity, the ideal air relative humidity is 65 70%, and it needs to be sprayed to the foliar surface frequently in the dry season of summer and autumn. The minimum humidity is generally not less than 50%, otherwise dry tip yellow leaves.

In summer and autumn, high temperature and high humidity weather should be strengthened to prevent root rot and stem and leaf rot.

3. Light: Jianlan likes to scatter enough light and is afraid of darkness, the sunlight illumination is generally 8000 10000lx is more suitable, 70 80% of the sunlight is shaded in summer and autumn, 30 40% is shaded in winter and spring, shade nets are used for cultivation in sheds or glass houses, and ordinary light-transmitting curtains are used for domestic cultivation. However, in winter and spring, when the daily temperature is below 10°, full sunshine can be accepted to facilitate warming and germination, and enhance the disease resistance of plants.

Build orchid blooming time.

The orchid blooms from June to October every year, during which the plant will bloom twice, the first flowering time is in late June, the flowering time is about 20 days, and the second flowering time is August, and the flowering period can last until October.

Build orchid maintenance during the flowering period.

Fertilization: Jianlan must do a good job of fertilizer during flowering, because plants need a lot of nutrients for flowering, but do not apply fertilizer with too high concentration, just apply an appropriate amount of phosphorus and potassium fertilizer.

Light: The orchid blooms in summer, but the plant does not like the sun, and the sunlight at this time is very strong, so it needs to be shaded from strong light, otherwise the plant may be burned.

Moisture: If Jianlan is raised outdoors, when it rains, it is necessary to do a good job of shading in time, so that the plants cannot be exposed to the rain, so as not to rot the roots.

Fertilize during the orchid flowering period.

Orchid can be fertilized during the flowering period, you can fertilize the plants at night, generally it is better to use slow-release fertilizer, and a part of it will be released into the soil every time you water.

Extend the flowering time of Jianlan.

1. If the orchid is too luxuriant during the flowering period, it is necessary to pay attention to pruning off some messy leaves and buds in time, and remove the weak flower buds to leave strong flower buds, which will be more conducive to its flowering for a longer time.

2. Do not move the root system of the plant when the orchid is flowering, whether it is to change the pot or divide the plant, and to keep the potting soil moist properly, so that the vitality of the root system is stronger, and the flowering period will be longer.

3. Fertilization should be stopped immediately after the orchid begins to grow buds, because the orchid buds have a good ability to absorb nutrients.

1. Potting soil: Cultivating Jianlan uses plant ash, river sand, and pastoral soil to prepare the base soil, and uses porous clay pots as planting utensils.

2. Light control: In spring and autumn, it is placed in a bright environment with bright light, and the light is 20%.

3. Temperature: The breeding temperature is kept at about 20 degrees. Imaginary bands.

4. Fertilizer and water: keep the soil moist during the peak growing season, and apply thin liquid fertilizer every 20 days.
