How to judge the survival of rose cuttings
Rose cuttings are a common propagation method, but many florists find it difficult to judge whether the cuttings were successful after the operation. This article will combine the popular horticulture topics on the Internet in the past 10 days, and conduct a structured analysis on how to judge whether rose cuttings are viable from aspects such as rooting performance, leaf status, and environmental factors, and provide practical tips.
1. Key indicators for survival of rose cuttings
The following are 4 core indicators for judging whether rose cuttings are viable:
| indicator | survival performance | failure performance |
|---|---|---|
| Root status | White or light yellow new roots appear at the incision | The incision turns black, rots or has no root growth for a long time |
| Blade status | New leaves sprout or old leaves remain green | Leaves wilted, yellowed or fell off |
| stem state | The stems are plump and without shrinkage | Stems dry, soft or black |
| growth cycle | Signs of growth appear within 2-4 weeks | No change over 6 weeks |
2. Environmental factors affecting the survival of cuttings
According to recent discussions among gardening enthusiasts, the following environmental conditions have a significant impact on the success rate of cuttings:
| factors | ideal range | Things to note |
|---|---|---|
| temperature | 18-25℃ | It is prone to dormancy when it is below 10℃, and it is easy to rot when it is above 30℃. |
| Humidity | 70%-80% | Need to cover with film or use spray to moisturize |
| light | scattered light | Avoid direct sunlight |
| matrix | Vermiculite/Perlite Blend | It needs to be loose and breathable to avoid hardening. |
3. Techniques for improving the survival rate of cuttings
Based on the sharing of recent popular experiments, the following methods are recommended:
1.Branch selection: Select semi-lignified branches (branches 1-2 weeks after flowering are best), about 0.5cm in diameter, and retain 2-3 bud points.
2.Root-promoting treatment: Dip in rooting powder or soak willow branches in water (recently popular methods on Douyin), which can increase the rooting rate by more than 30%.
3.Conversion of water cuttings to soil culture: According to actual measurements by Xiaohongshu users, the survival rate is 50% higher than direct soil transplantation when the roots are grown in water and then transplanted.
4.Moisturizing bag: Weibo experts recommend covering it with a transparent plastic bag and ventilating it for 10 minutes every day to prevent mold growth.
4. Frequently Asked Questions (Q&A)
Q: Does the leaf falling after cutting mean failure?
A: Not necessarily. The shedding of old leaves may be a normal phenomenon during the adaptation period. If the stems are still plump and have swollen new buds, they may still survive.
Q: How to check whether roots have taken root without damaging the seedlings?
A: Gently lift the branches. If there is obvious resistance, it means roots have taken root (recent actual measurement method of the UP master at Station B).
Q: When can cuttings be transplanted?
A: When new roots grow to 3-5cm and new leaves unfold (about 4-6 weeks), transplanting needs to be avoided during high temperature and rainy seasons.
5. Summary
Determining whether a rose cutting is viable requires comprehensive observation of roots, leaves, stems, etc., as well as controlling environmental conditions such as temperature and humidity. The recently popular methods of converting hydroponics to soil cultivation and using switch water to promote roots are worth trying. If the cutting fails, it is recommended to analyze the specific reasons (such as excessive moisture in the substrate, uncomfortable temperature, etc.) and adjust the plan.
