Fraxinus paxii is a common ornamental plant, not only with beautiful leaves but also an elegant tree shape. It has diverse propagation methods, and cuttings are one of the commonly used methods. However, how long it takes for Fraxinus paxii cuttings to root often raises questions. This article will focus on the rooting time of Fraxinus paxii cuttings, explore its influencing factors and the best time, and provide a reference for enthusiasts.
I. Factors Affecting the Rooting of Fraxinus paxii Cuttings
1. Selection of Buds
When propagating by cuttings, select vigorous buds. The young tissue at the bud contains high levels of plant auxin, which is conducive to rapid rooting after cutting.
2. Nutrient Solution Formula
The composition and concentration of the nutrient solution have a significant impact on the rooting of Fraxinus paxii cuttings, and it is necessary to choose a suitable nutrient solution formula and concentration.
3. Temperature and Humidity
The influence of temperature and humidity on the rooting of Fraxinus paxii cuttings is also very important. It is necessary to maintain a suitable temperature and humidity environment to facilitate rooting after cutting.
II. The Best Time for Cuttings
4. Spring
Spring is the best time for Fraxinus paxii cuttings. At this time, the temperature is suitable and the relative humidity is high, which is conducive to rooting after cutting.
5. Summer
Although the temperature is high in summer, cuttings can be carried out in a greenhouse or under a shade net to create suitable temperature and humidity conditions.
6. Autumn
The temperature in autumn is suitable and the relative humidity is high, making it another suitable season for Fraxinus paxii cuttings.
7. Winter
Winter is generally not suitable for Fraxinus paxii cuttings because the temperature is too low, which can easily lead to the death of the seedlings.
III. Common Cutting Methods
8. Stem Cutting Method
Cut the new shoots or old branches of Fraxinus paxii into 3-5 cm stem segments, remove the leaves and flowers, apply rooting powder to the cut end, and then insert them into the culture medium.
9. Leaf Cutting Method
Insert healthy leaves of Fraxinus paxii into a shallow tray, inserting each leaf 1-2 cm deep. After planting, water thoroughly and maintain a moist environment.
10. Pot Cutting Method
Propagate Fraxinus paxii in seedling trays, keep the soil moist, and fertilize regularly.
11. Bottle Cutting Method
Place Fraxinus paxii stem segments in a clear glass bottle with the mouth placed in water, ensuring the stem segments can absorb sufficient moisture.
IV. Post-Cutting Care
12. Watering
After cutting, it is necessary to water in a timely manner to keep the soil moist, but do not overwater to prevent root rot.
13. Shading
The tender stems and leaves of cuttings can be easily scorched by strong sunlight, so it is necessary to set up a shade net or sunshade cloth in the cutting area.
14. Heat Preservation
For Fraxinus paxii that needs to be propagated in a low-temperature environment, heat preservation measures are necessary.
15. Pest Control
The tender stems and leaves of cuttings are susceptible to pest infestations and require regular inspections and the use of pesticides for control.
The rooting time of Fraxinus paxii cuttings is related to many factors. By choosing a suitable cutting time and method, and mastering the correct care techniques, the success rate of rooting can be improved. It is hoped that this article will provide a reference for enthusiasts and help you propagate Fraxinus paxii with greater ease.
