What happened to the new branches of the rose that withered overnight?
Today, the editor will explain the small experience of plant cultivation about why the new branches of the rose withered overnight. Let's learn about it together below.
Yesterday, two flower enthusiasts asked such a question: The new shoots of the rose were growing well, but suddenly they wilted. What's going on?
Let's first look at the situation encountered by a flower enthusiast from Anhui: These new shoots of the rose have already grown quite large, but suddenly the top new shoots all wilted. What's the matter? Is it a disease or pest damage?
Seeing this picture, the first thought is rose stem sawfly, but upon closer inspection, it seems unlikely. Although the rose stem sawfly can cause the tender branches of the rose to lose water and droop, its destructive power is limited and it is unlikely to cause such a large area of new branches to wither overnight.
Let's also see that it is not completely the new branches that withered. The lower leaves also show obvious wilting. So what exactly caused it?
Think about it first, and then let's take a look at the problem encountered by another flower enthusiast.
This pot of rose belongs to a flower enthusiast in the north. It originally sprouted well, but after moving it outdoors for two days, this situation occurred, and all the new shoots wilted.
What do you think might have caused it?
There was a temperature drop in the past few days, and it is likely that the temperature drop in Anhui was even greater. You can see a glimpse of it from the temperature in the past two days.
Although roses are cold-resistant, the new shoots are not frost-resistant. Therefore, special attention should be paid to the impact of early spring temperature drops on the new shoots of roses. The newly grown new shoots are very tender, and if they encounter frost at this time, they are very likely to be frost-damaged.
When the night temperature of outdoor roses drops below 4 degrees, it is necessary to cover them to prevent frost. For potted roses in the germination period, it is best to move them to a place where they cannot be hit by frost or keep them indoors for safer keeping.
Our northern flower enthusiasts should not rush to let the roses go outdoors at this time. The temperature is not stable, and it is easy to freeze the new shoots. If moved outdoors during the day, they should also be moved indoors at night.
