How to deal with the dried leaves of Chinese roses
The editor will introduce to everyone how to deal with the dried leaves of Chinese roses in the aspect of green plants and flowers, with the following specific content:
Actually, similar situations have been mentioned in previous articles. Today, let's take advantage of our flower enthusiast's Chinese rose to do a detailed case analysis.
First, let's take a look at the condition of this Chinese rose. When the flower enthusiast found it, the leaves of this Chinese rose had lost water and become very brittle, crumbling at the touch.
Because it is a screenshot from a video, the picture may not be very clear, but it can be roughly seen that the leaves are still in a green state overall, but they have already become dry and brittle.
For our新手 Chinese rose growers, what is your first reaction when encountering this situation? You may feel confused, what's going on? Fertilizer damage? Pesticide damage? But no pesticides or fertilizers were applied. Could it be too much watering? But too much watering should cause yellowing and falling leaves.
The first thought upon seeing this Chinese rose is - there are pests.
This is a Chinese rose with its main stem eaten by borers. This type of borer usually occurs in the summer, and the Chinese rose withers in the autumn season. In the early stages, it develops slowly and is not easy to detect, and by the time it is discovered in the autumn, it often has already caused serious consequences.
If it is windy, the Chinese rose branches and leaves may suddenly lose water and become brittle. If there is no strong wind and the water does not dissipate in a short time, the branches and leaves of the Chinese rose will also slowly show signs of yellowing and withering, giving the impression that the Chinese rose is malnourished. In fact, it is the borers that have eaten away the main stem and main roots of the Chinese rose.
How to deal with the dried leaves of Chinese roses
If the borers have eaten into the main branches of the Chinese rose, you can often see a lot of sawdust-like material on the potting soil at the base of the main roots. This is what the borers leave behind, which you can simply understand as the borer's excrement. (As shown in the picture above)
When the Green Plant Enthusiast Network told the flower enthusiast that the Chinese rose was eaten by borers, this enthusiast took immediate action and pruned the Chinese rose, kudos for your proactive approach! Then he made a big discovery: he found that the center of this branch was hollow.
Next, he dug up the soil around the Chinese rose and made a breakthrough discovery: a big worm!
It was this worm that ate away the woody part of the Chinese rose branches and the main stem, preventing the Chinese rose from absorbing and transporting nutrients properly. As the severity of the borer infestation increases, the leaves of the Chinese rose will slowly turn yellow. If there is sufficient fertilizer and water in the early stages, there may not be any obvious signs, but once遇到 strong wind, the water dissipates quickly and the leaves easily become dehydrated and brittle, at which point it is too late to save the plant.
