Why do climbing roses become weaker the longer they grow?
Today's sharing: knowledge about why climbing roses become weaker as they grow, with specific introduction as follows:
Why do climbing roses become weaker the longer they grow? This reason may surprise you.
In the Aiwen Circle, a flower friend asked: Does this pink Dragon Sands stone have a nutrient deficiency? The leaves are yellowing and look unhealthy.
From the picture, we can see that this pink Dragon Sands stone is indeed not very healthy. However, this unhealthiness is not caused by a simple nutrient deficiency, but rather a typical lack of fertilizer, specifically a lack of all-element fertilizer. By observing the branches and leaves of this plant, we can see that the branches are very thin and short, with obvious short and weak branches. Moreover, the long branches are all relatively old ones, and there are almost no new branches from this year, at least no strong ones. However, this rose plant does not have spider mites and is not troubled by black spot disease. It can still have so many leaves after enduring a summer, which means that the control of diseases and pests is still quite good.
It seems that the owner of this Dragon Sands stone has managed it quite well. Then why is there such an obvious lack of fertilizer? Let's analyze some of the hidden reasons.
Reasons for the lack of fertilizer and growth in climbing roses
Firstly, we need to understand that there are two main reasons for the severe lack of fertilizer in climbing roses: one external and one internal.
1. External reasons for the lack of fertilizer and growth in climbing roses
External factors refer to our daily management, such as not applying additional fertilizer for a long time, especially for potted climbing roses. If potted climbing roses do not receive additional fertilizer for a long time, they will become weaker due to a lack of sufficient nutrients.
Why do climbing roses become weaker the longer they grow?
This problem is not only found in potted plants, but also in ground plants, which can be affected by insufficient fertilizer and slower growth. A common case is that the first year's growth of climbing roses is very fast, producing many strong long branches, followed by a large number of flowers in the second spring. If the same amount of fertilizer as the first year is applied after flowering in the second year, the climbing roses will show signs of weakened growth, with few strong suckers or明显 weak suckers, which is all due to insufficient fertilizer and water.
The fast growth in the first year is because very few flowers are produced, and all the nutrients are used for growing branches, resulting in thick and strong suckers. However, the large number of flowers in the spring consumes a lot of nutrients. If the fertilizer is not replenished properly after flowering, it is easy to show signs of weak growth.
2. Internal reasons for the lack of fertilizer and growth in climbing roses
Green plant enthusiasts know that many flower friends are very willing to apply additional fertilizer to climbing roses. However, despite applying a lot of fertilizer, the climbing roses still do not produce suckers and remain with only a few old branches. It's a dilemma whether to dig them up or not.
When this phenomenon occurs, we need to find the cause. If this climbing rose is a large plant over 1 meter tall that we bought, and it has produced quite a few flowers but then stops growing, Green plant enthusiasts personally suggest removing it early and not wasting time.
There is another situation where we have raised the plant ourselves, originally planted in the ground and then transplanted to a new location. However, the transplanting was not done with a heavy pruning, and the long branches were transplanted. In this case, Green plant enthusiasts also suggest replacing it.
