Why do the leaves of Clematis turn brown and crispy?
Let's talk about the topic of why the leaves of Clematis turn brown and crispy. Next, the editor will introduce it.
During this period, there has been a continuous spell of cloudy and rainy weather. While rainwater can moisturize our flowers and trees, too much rain can also cause damage to our plants. Just the other day, a gardening enthusiast asked a question: their Clematis has black new buds and withered, and they don't know the cause. Let's take a look together.
The picture shows that the new leaves of Clematis have obvious signs of browning and crispness. Whether it's Clematis, roses, or other flowers, when new leaves show signs of browning and wilting, we should first rule out fertilizer and pesticide damage, these two man-made factors.
If there has been no spraying or fertilizing recently, and yet the new leaves are wilting, it usually indicates a problem with the plant's root system.
As for the reasons for the root system problems, we need to analyze and judge comprehensively based on recent maintenance measures and the weather.
Common causes of root damage are as follows:
1. Root rot caused by waterlogging
Waterlogging causing plant roots to rot is the most common cause of root damage. In the process of managing potted plants, repeated watering without a dry-wet cycle can easily lead to anaerobic respiration in the roots, causing root rot.
In outdoor cultivation, continuous cloudy and rainy weather can also cause waterlogging in the potting soil, leading to root rot. As mentioned at the beginning, the Clematis of the gardening enthusiast mentioned was affected by excessive rain, causing root rot.
Why do the leaves of Clematis turn brown and crispy?
Although ground planting is generally less troublesome than potted plants, encountering continuous rainy weather without proper drainage can actually lead to easier waterlogging and root rot, because garden soil is heavier and continuous rainy weather can easily cause poor drainage, leading to root suffocation.
Plants like Clematis and roses, which are not tolerant to waterlogging, should have drainage ditches dug in case of continuous rain to prevent waterlogging and root rot.
So, what should be done if a Clematis, like the one mentioned by the gardening enthusiast, has already rotted its roots? The better solution is to dig it up and pot it, as it is now autumn and the weather is relatively cool, plus the continuous cloudy and rainy weather, making it easier for the potted plant to survive. If left in the ground and it continues to rain, it will be harder for it to survive.
2. Excessive drought
In addition to waterlogging, excessive drought can also cause the plant's fine roots to dry up. In dry seasons, it is important to maintain sufficient water and fertilization, and water the plants in time. Even for ground-planted roses and Clematis, when the soil is dry, it is necessary to water them promptly.
