Compared to the related content about the reasons and remedies for withered leaves of Phalaenopsis orchids that most people are familiar with, let's take a look together!
Reasons and Remedies for Withered Leaves of Phalaenopsis Orchid
There are many reasons for the withered leaves of Phalaenopsis orchids, including excessive watering, high temperature, strong light, and nutrient deficiency, all of which can cause the leaves to wither. If excessive watering leads to withered leaves, they need to be placed in abundant sunlight for careful nursing; if nutrient deficiency causes the leaves to wither, an immediate application of a large amount of compound fertilizer to the potting soil is required, and the environmental temperature should be maintained above 10°C to help it recover as soon as possible.
Reasons for Withered Leaves of Phalaenopsis Orchid
1. Excessive Watering: Excessive watering can lead to积水 in the potting soil of Phalaenopsis orchids, and after the roots are damaged, it is difficult for the plant to absorb nutrients, causing the petals to wither.
2. High Temperature: Phalaenopsis orchids prefer warm temperatures, with the most suitable growth temperature being between 16°C and 30°C. The temperature during the growing period should not be lower than 15°C. High temperatures can cause the orchids to wither, which is not conducive to the growth of the plant.
3. Strong Light: Phalaenopsis orchids prefer to grow in a cool and well-ventilated environment. Long exposure to direct sunlight can cause the petals to wither. It is important to provide timely shading and avoid direct sunlight.
4. High Fertilizer Concentration: High fertilizer concentration can also cause the orchid flowers to wither.
What Happens if the Leaves of a New Phalaenopsis Orchid Wither
The withered leaves of a new Phalaenopsis orchid may be due to not having adapted to the environment yet. Once it adapts, increasing the time it spends in the light will restore its normal state.
Remedies for Withered Leaves of Phalaenopsis Orchid
1. Reduce Light: Although Phalaenopsis orchids enjoy sunlight, they are not suitable for direct exposure to sunlight. Otherwise, the leaves can become soft and withered. They need to be moved to a semi-shaded environment for care, and water should be sprinkled on the leaves to help them recover more quickly.
2. Control Watering: If excessive watering causes the leaves to become soft and withered, it is necessary to control the amount of water and place the plant in abundant sunlight for careful nursing. In severe cases, it may be necessary to dig it out of the potting soil, treat the rotting roots, and then repot with fresh soil.
3. Apply Fertilizer: Phalaenopsis orchids require sufficient nutrients. If there is a deficiency, the leaves will also become soft and withered. It is necessary to apply a large amount of nitrogen-phosphorus compound fertilizer and an appropriate amount of potassium compound fertilizer to the potting soil immediately.
4. Insulation Measures: Generally, Phalaenopsis orchids are not cold-resistant and can be easily damaged by frost, leading to withered and soft leaves. They need to be moved to a warm environment and maintain an environmental temperature above 10°C to help with winter growth.
What to Do if the Leaves of a Recently Repotted Phalaenopsis Orchid Wither
The withered leaves of a Phalaenopsis orchid after repotting are due to the roots not having adapted to the new potting soil yet. The roots cannot absorb water and nutrients to meet the needs of the leaves. At this time, the orchid will slowly sacrifice old leaves to maintain its life, achieving a reasonable replacement of old and new leaves. Once new buds grow, there won't be a problem.
The above is a detailed explanation of the reasons and remedies for withered leaves of Phalaenopsis orchids, for your reference and suggestions!
