Orchids are elegant and graceful plants that not only decorate our homes but also purify the air. However, many people are confused about the issue of repotting orchids. Today, let's learn together about the timing and methods for repotting orchids.
I. Why Repot is Needed
The reason for repotting is that orchids continuously absorb nutrients and water during their growth process, causing the nutrients and water in the soil to gradually be depleted. When the nutrients and water in the soil are no longer sufficient to meet the orchid's growth needs, it is necessary to transplant the orchid into new soil.
II. Choose the Right Time
The timing for repotting is very important. Repotting is usually done in spring or autumn. Because the temperature is moderate and the soil is moist in spring and autumn, which is beneficial for orchid growth. Repotting in summer or winter can easily cause harm to the orchid.
III. Prepare the Potting Soil
Before repotting, you need to prepare new potting soil. The potting soil should be loose, breathable, and have good water retention. You can choose specialized orchid potting soil or make your own with the following ratio: three parts each of garden soil, leaf mold, and vermiculite, one part perlite, and one part sand.
IV. Prepare a New Pot
The pot should have good breathability and be of a suitable size. Do not choose a pot that is too large or too small. Some small stones or granite should be placed at the bottom of the pot to facilitate drainage.
V. Remove the Orchid
Take the orchid out of its original pot. Gently tap the pot walls to separate the soil from the roots.
VI. Trim the Roots
When trimming the roots, be careful not to damage them. Trim away old, dead, and weak roots, leaving only the healthy roots.
VII. Transplant the Orchid
Transplant the orchid into the new pot. First, pour a layer of potting soil, then place the orchid in the pot. Adjust the position, then add more potting soil, firming the soil until there is about a 2 cm gap left at the surface.
VIII. Watering
After transplanting, water it thoroughly in a timely manner so that the soil can make close contact with the orchid's roots. But do not water when the sun is shining directly. It is best to water in the morning or evening.
IX. Fertilizing
Proper fertilization can promote the growth of orchids, but do not overdo it. It is recommended that each application of fertilizer should not exceed 1/5 of the soil volume, and fertilizing once a month is sufficient.
X. Control Temperature and Humidity
The suitable temperature for orchid growth is 20°C to 30°C, and the humidity should be kept between 60% and 80%. To maintain humidity, you can spray water around the pot or place the pot in a moist environment.
XI. Pay Attention to Light
Orchids like light, but cannot be exposed to strong sun. It is best to place the pot in a place with light but not direct sunlight, avoiding prolonged exposure to the sun.
XII. Regularly Clean the Leaves
Regularly cleaning the leaves can remove dust and dirt, maintain the leaves' permeability, and is beneficial for the orchid's growth.
XIII. Prevent Pests and Diseases
Regularly check the orchids for pest and disease infestation, take timely measures for prevention and control to avoid harming the orchid.
XIV. Pay Attention to the Dormant Period
Orchids have a dormant period every year. During this period, reduce watering and fertilizing to avoid affecting the orchid's growth.
XV.
Repotting orchids not only provides a suitable growing environment but also promotes their growth and flowering. However, during the repotting process, be gentle to avoid damaging the roots. Only by choosing the right time and method can you make your orchids shine more beautifully.
