How to solve the problem of roses growing wildly but not flowering?
The editor will explain how to solve the problem of roses growing wildly but not flowering in the field of green plants and flowers, and then let everyone understand together.
This is the 836th day of the original article every day.
This article is one of the original theories.
Excerpt from the "Three-Step Method of Rose Cultivation" series.
For a period of time, I have been sharing articles about fertilizing roses to promote flowering, among which some flower friends asked:
"Why do my roses only grow tall and not bloom?"
Today, let's talk about why your roses are徒有虚名, only growing leaves and not flowering.
Rose flowers, as the name implies, can bloom every month, but why do your roses only grow leaves and not bloom?
To clarify this issue, we first need to understand the main factors affecting rose flowering.
Factors affecting rose flowering:
1. Light
Roses are sun-loving flowers and require sufficient light to bloom normally. For roses, at least 4 hours of direct sunlight should be guaranteed every day.
If the duration of light is too short, it is easy to cause excessive growth, resulting in only leaves and no flowers.
2. Fertilization
The second major factor affecting rose flowering is fertilization. You might say, "I have fertilized, the branches are long, the leaves are large, but still no flowers!"
What kind of fertilizer did you use?
Previous articles mentioned that nitrogen promotes leaf growth and phosphorus promotes flower growth. If you have been applying a large amount of nitrogen fertilizer to roses, it can easily lead to excessive nitrogen and a lack of phosphorus and potassium fertilizers, causing excessive growth.
Excessive nitrogen can be corrected by stopping the application of nitrogen fertilizer and switching to phosphorus and potassium fertilizers.
Caution:
When fertilizing roses, it is also important to grasp the balance. Whether it's nitrogen or phosphorus and potassium fertilizers, neither should be applied excessively. Applying different fertilizers in different growth stages is truly beneficial for rose growth.
3. Pruning
Pruning has a direct impact on rose flowering.
Because roses bloom on new branches, there can only be flowers if there are new branches. If we do not prune for a long time, roses will not have new branches, and naturally, there will be no flowers.
That's why we always say, roses love to be mistreated, just cut, cut, cut!
4. Blind Branches
In addition to the above three main factors, blind branches are also a common reason for roses not flowering.
There are many reasons for the appearance of blind branches, but ultimately it is due to malnutrition.
The malnutrition mentioned here does not only refer to insufficient fertilization. Insufficient light, poor root growth, and insufficient water and fertilizer can all lead to malnutrition and the formation of blind branches.
Blind branches do not flower, and if not pruned, they will not easily produce new branches, which can lead to roses remaining in a state of growth stagnation without flowering.
For blind branches, timely pruning is essential to stimulate regrowth and produce branches.
The probability of flowering increases significantly with the production of new branches, but of course, proper management is still required.
5. Variety
What has been mentioned above are external factors affecting rose flowering, but in fact, the inherent factors of roses also affect their flowering.
For example, some single-season blooming rose varieties may easily show fewer or no flowers when cultivated in the warm regions of Guangdong and Guangxi.
And some varieties are naturally strong in growth, can grow rapidly with a bit of fertilizer, but may not necessarily flower, which we commonly call "Green Giants." For these types of rose varieties, it is more suitable for pot cultivation to control the amount of fertilizer.
If grown in the ground, water and fertilizer should be reduced, and pruning should be frequent.
Representative varieties of "Green Giants": Jansen and Freedom Spirit.
Facing the problem of roses not flowering, there is no need to feel surprised, just identify the cause and solve the problem.
Both climbing roses and "Green Giants" varieties have the characteristic of flowering on weak branches. If you want them to bloom more, try to reduce the existence of strong branches and make them produce more weak branches.
That's all for the problem of roses not flowering.
Have you ever encountered this situation:
A healthy rose shoot with flower buds suddenly droops its head?
