How to save the weak rose seedlings?
The editor introduces you to the related content on how to save weak rose seedlings in the aspect of green plants. The specific introduction is as follows:
It has been raining for a month continuously. Over the past two days, every time I open my phone, I see videos of "watching the sea at home and catching fish in the park". This year's rainfall is indeed a lot, which has caused considerable trouble for us, the rose-growers.
Long periods of rain have caused a large number of yellow leaves on the roses, and even turned them into bare sticks. The originally strong rose seedlings have become weak ones. Facing these bare-stemmed roses, what should we do? Many friends think of adding fertilizer immediately to stimulate new growth in the roses. If you really do this, what awaits you might be a large number of black stems and withering.
So what should we do exactly?
If the roses have turned into bare sticks and you want them to sprout new buds as soon as possible, adding fertilizer is necessary, but there is still some explanation needed for the choice of fertilizer.
1. Fertilization should be gradual.
Weak seedlings need nutrient support to grow new buds, but because they have no leaves, their metabolism is relatively slow. Therefore, fertilization should be gradual. If using fast-acting water-soluble fertilizer, it needs to be diluted to a much higher ratio.
For example, if the original concentration is 1000 times, but since the seedlings are weak, the concentration needs to be diluted to 2500-3000 times. If the normal fertilization concentration is used, it is easy to cause fertilizer damage, leading to root rot and black stems in the roses.
How to save the weak rose seedlings?
A safer approach is to apply fermented organic fertilizer to the bare-stemmed roses. Organic fertilizer has a relatively gentle effect and lasts for a longer time, continuously providing nutrients to the roses, meeting their nutrient needs for sprouting new buds.
2. Appropriate water control.
Without leaves, the metabolism of roses slows down, and the evaporation rate decreases. Therefore, attention should be paid to controlling the amount of watering. If too much water is added, the accumulated water in the pot soil can easily cause root suffocation and lead to withering.
Therefore, for bare-stemmed roses, it is necessary to control water appropriately, especially in summer. If the roses grow new buds quickly, then the fertilizer and water can be kept sufficient. If they don't sprout new buds for a long time, it might be because the weather is very hot and they have entered a dormant state. In this case, it is even more important not to water too much and to adhere to the principle of watering when the soil is completely dry.
3. Appropriate supplementation of trace elements.
Often, after the roses turn into bare sticks, the new buds that grow are yellowish, looking very unhealthy, which is actually due to a deficiency of trace elements.
