What's going on when the rose bud falls off while growing?
An article about small knowledge sharing, introducing the reason why the rose bud falls off while growing in terms of plant knowledge. Next, the editor of the website will introduce to the netizens.
Why does the rose bud wither while growing? Have you encountered this problem? For those who grow roses in pots and do not thin the buds, this phenomenon should be very common. So what is the reason? Let's talk about the causes of this problem.
Causes of yellowing and falling off of rose buds
There are many reasons for the yellowing and falling off of rose buds, which can be roughly divided into the following two types, and specific judgment still needs to be situation-dependent.
1. Drought
Drought is one of the most common reasons for the falling off of rose buds. Especially in spring, when the weather is clear, the transpiration of roses is strong, and water consumption is fast. If the plant is large and the pot is small, or if a root-controlling pot is used, it is easy to have water deficiency.
Once the rose is excessively dehydrated, the tender branches of the rose will become dry. In order to maintain its strength and survive, the rose will choose to abandon the buds.
Therefore, after experiencing drought, the rose buds are prone to turn yellow and fall off. So, friends using small pots and root-controlling pots should pay special attention to observe the changes in the potting soil and supplement water in time.

In addition, newly transplanted roses are also prone to water deficiency because the new roots have not grown yet, and the water consumed is still from the original soil. It is easy to have the phenomenon where the new soil is not dry, but the original soil is very dry. Therefore, for newly transplanted roses, special attention should be paid to observe the dryness and wetness of the original soil mass. If the original soil mass is dry or the rose leaves are wilted, not fresh, these are all signs of water deficiency, and water should be supplemented in time.
2. Lack of fertilizer
Besides drought, lack of fertilizer is also a very important reason. You might say, I fertilize every week. Can there still be a lack of fertilizer?
There are also many situations of fertilizer deficiency, for example, insufficient light, after the rose has grown buds, there is prolonged cloudy and rainy weather, or it is placed in a hidden place, leading to insufficient light and nutrient deficiency, resulting in bud drop.
However, in more cases, the large and medium-sized rose buds bloom normally, while the smallest buds slowly turn yellow and wither.
This situation is very common in multi-head rose varieties, especially when fertilization is stopped during the flowering period, it is very easy for small buds to fall off. The root cause is that the large buds consume a lot of nutrients, and the small buds do not get sufficient fertilizer and water nourishment, so they are naturally eliminated.
