As an elegant plant, orchids are deeply loved by people. However, there are many precautions to take when cultivating orchids, among which root rot is one of the most common problems. Once an orchid's roots rot, it will affect its normal growth and development, and may even lead to the death of the plant. When root rot is discovered in an orchid, we need to take timely measures to deal with it.
I: How to determine if an orchid has root rot?
If the leaves of an orchid start to turn yellow, or even become soft, and the stem turns black, these are signs of root rot. In addition, if an orchid is soaked in water for a long time, it may also cause root rot.
II: Why are orchids prone to root rot?
There are many reasons for orchid root rot, the most common of which are overwatering and poor drainage. This causes water to accumulate in the soil, creating an oxygen-deficient environment, which in turn leads to root rot.
III: Basic methods for saving a plant with root rotAfter an orchid's roots have rotted, it is necessary to take remedial action in a timely manner. The most basic method is to cut off the rotten parts of the roots, and sprinkle charcoal powder or flower charcoal on the cut surface of the healthy roots with clean tools to prevent bacterial infection. Then, move the orchid to new soil to grow.
IV: How to choose new soil?
When choosing new soil, we should select soil that is breathable, well-draining, and has good water retention. You can use some special mixed soils suitable for orchid growth, or prepare your own soil mixture suitable for orchids.
V: How to change the new soil?
When changing the soil, we should first take the orchid out of the old soil, and then clean the roots. Then, place the orchid in the new soil, gently pat it down, and press the soil lightly with your hands to ensure it makes contact with the orchid's roots.
VI: How to water correctly?
Watering is a very critical part of orchid growth. When watering, it is important to be moderate and not to overwater. Just keep the soil moist. Do not let water accumulate at the bottom of the pot to avoid causing root rot.
VII: How to prevent orchid root rot?
To prevent the occurrence of orchid root rot, we need to take some preventive measures. First, pay attention to drainage, maintaining the soil's aeration and drainage. Avoid overwatering; only water an appropriate amount when the soil surface is slightly dry.
VIII: How to prevent root rot infection?
When dealing with orchid root rot, we need to pay attention to disinfecting tools and hands, and use substances like plant ash to disinfect after cutting off the rotten roots to prevent infection.
IX: How to ensure proper light and temperature?
Orchids have relatively high requirements for light and temperature, so it is important to ensure they get the right amount. Generally, keep the indoor temperature around 20-25 degrees Celsius, and the light intensity should also be moderate.
X: What kind of fertilizer should be used?
For fertilizer selection, we should choose fertilizers rich in organic matter, and be careful not to over-fertilize, as this can harm the orchid.
XI: How to prune?
When pruning, we should keep our tools clean and disinfected, and use substances like plant ash to disinfect after pruning to prevent infection. When pruning, avoid damaging healthy parts.
XII: How to maintain air humidity?
Orchids have relatively high requirements for air humidity, so we should pay attention to maintaining it. You can use a sprayer or other methods to increase indoor air humidity.
XIII: How to prevent pests?
During the growth process of orchids, pests often appear, which can affect their normal growth. We need to take some pest control measures, such as spraying with insecticides.
XIV: How to maintain the growing environment?
To maintain a good growing environment, we need to regularly change the soil, clear weeds, and pay attention to regular inspection and maintenance of the orchid.
