Techniques for transplanting osmanthus trees and key steps for ensuring their survival.

How to Ensure the Survival of Osmanthus Tree Transplantation

As one of the top ten famous traditional Chinese flowers, the osmanthus tree is deeply loved by people for its fragrant aroma and auspicious meaning. However, a slight mistake during transplantation can lead to the withering of the plant. This article systematically analyzes the core techniques for ensuring survival from the timing of transplantation to post-transplant care.

I. Scientifically Mastering the Timing of Transplantation

1.1 Best Season Selection

In spring, from March to April, when the surface temperature stabilizes above 15°C, the roots of the osmanthus tree enter an active period, and transplantation at this time can shorten the acclimatization period. Experimental data shows that the survival rate of spring transplantation is 67% higher than that of summer.

1.2 Weather Conditions Control

Choose to operate on consecutive cloudy days or in the evening of sunny days to avoid excessive transpiration caused by high temperatures at noon. Stop watering 3 days before transplantation to keep the soil moderately dry for easier digging with soil.

II. Refining Seedling Operation

2.1 Soil Ball Standard Specifications

Determine the diameter of the soil ball according to 6-8 times the diameter of the trunk, with the depth reaching 20cm below the main root. Use straw rope for mesh binding, and place the soil ball towards the direction of the vehicle during transport.

2.2 Root Protection Measures

Immediately apply ABT root-promoting powder to broken roots, and seal cuts larger than 2cm in diameter with a wound healing agent. Use a shade net to cover during transport to prevent direct sunlight from causing the soil ball to crack.

III. Professional Handling of Transplantation Details

3.1 Root Disinfection Treatment

Soak the roots in a 50% carbendazim solution diluted 800 times for 20 minutes, focusing on the decayed parts. After pruning, retain roots of the third level or higher to ensure absorption capacity.

3.2 Preparation of Planting Hole

The diameter of the hole should be 40cm larger than the soil ball, with a 15cm layer of gravel at the bottom. The backfill soil should be mixed in the ratio of original soil: humus soil: river sand = 5:3:2, and add an appropriate amount of slow-release fertilizer.

IV. Systematic Post-Planting Care

4.1 Standard Planting Operations

Keep the original planting depth, ensuring close contact between the roots and soil. Use a layered backfill method, compacting every 20cm, and finally create a 10cm water-retaining dike.

4.2 Key Points for Post-Planting Care

Water thoroughly in three installments, and combine the application of EM bacteria solution to promote root growth. Spray daily for the first 15 days to keep moist, and after 60 days, apply diluted organic fertilizer.

By precisely controlling each step of transplantation and combining scientific care management, the survival rate of osmanthus tree transplantation can reach over 92%. It is recommended to regularly check the soil EC value and adjust the care plan in a timely manner to keep the transplanted osmanthus tree thriving.
