Have you encountered the situation where the rose seedlings you bought just a few days ago have blackened stems and died?
Today, I will introduce to everyone the knowledge about roses that have blackened stems and died shortly after purchase. Next, the editor will introduce some information.
This is the 891st day of the daily original article.
Rose cultivation series article: the 88th article
Today, let's talk about a relatively sensitive topic:
I believe many people have had such an experience:
Looking at the seemingly healthy rose seedlings, after bringing them home, preparing the soil, repotting, watering, and fertilizing, they find that the rose has blackened stems and is about to die within a week.
This problem is quite common among novice flower enthusiasts. Many people think there is a problem with the seedlings, but most of the time, it is our own cultivation methods that are the issue.
Flower enthusiasts who have bought rose seedlings at home know that the rose seedlings at home are quite sturdy. However, I received feedback from a flower enthusiast customer yesterday, who said that the rose seedlings they bought at home have blackened stems and are about to die after just one week.
This is quite shocking. To be honest, I am a very lazy person and rarely take good care of flowers, and I don't have much time to manage them either. The roses I get from the nursery are usually just thrown outside, and I often only water them when they look wilted. Even so, they still grow well after a month. I'm curious how this flower enthusiast managed to kill the rose in such a short time.
Have you encountered the situation where the rose seedlings you bought just a few days ago have blackened stems and died?
Let's find out together.
First, let's start by asking about soil preparation and seedling acclimatization. Before potting the roses, the flower enthusiast mixed carbendazim into the soil to sterilize it and used a general-purpose nutrient-rich soil.
About this step, I want to share two personal opinions:
First, should new soil be sterilized with carbendazim?
I personally do not recommend adding fungicides to new soil during repotting. Firstly, properly stored new soil does not have many pathogens, and if disinfection is needed, I suggest using the sun exposure method.
I do not recommend using fungicides during repotting mainly because I am worried that the concentration of the medicine may not be properly controlled. The seedlings that have just been repotted need time to adapt, and during this period, their resistance to external stimuli is relatively weak. If the concentration of the medicine is too high, it may directly damage the roots of the roses. And if the concentration is too low, it may not have a fungicidal effect.
Second, try to avoid using general-purpose nutrient-rich soil!
I have said this more than once before: do not use general-purpose nutrient-rich soil to plant roses, accurately speaking, not just roses, do not use pure general-purpose nutrient-rich soil to plant any flowers!
Because the quality of the general-purpose soil on the market is really not up to par. It has very poor air permeability and water permeability, and it takes a long time to dry after watering, which is very prone to root rot.
