Pomegranate Tree Old Stump Sprouting Time
The old pomegranate stump is loved by gardening enthusiasts for its sturdy and ancient branches, but the sprouting time after transplanting and potting operations often puzzle growers. Mastering the correct care techniques can help your old stump pomegranate revive.
Detailed Explanation of Pomegranate Old Stump Sprouting Cycle
Seasonal Temperature Impact
In the Yangtze River Valley, sprouting usually begins in mid-March, while in the northern regions, it may be delayed until early April. Ground-planted old stumps sprout 7-10 days earlier than pot-planted ones, with a stable ground temperature above 12℃ being most conducive to bud germination.
Root Recovery Observation
It takes 20-35 days for root growth after transplanting, and healthy stumps will leaf out around Qingming Festival. If the epidermis of the branches appears green, it indicates that the sprouting stage is approaching.
Core Techniques for Transplanting Pomegranate Old Stump
Timing for Transplanting
The best time is from Jingzhe to Chunfen (daily average temperature of 8-15℃), when the sap starts to flow but has not consumed a large amount of nutrients. Avoid repotting during the flowering bud differentiation period (May-June) and in the hot season.
Soil Operation Specifications
Retain the original soil ball with a diameter of over 30cm and secure it with straw rope. For bare-root transplanting, keep the main root length over 40cm and protect the roots with yellow mud slurry.
Scientific Watering Management
The root-setting water should be watered in two installments: after the first infiltration, water again after a 2-hour interval. Maintain soil moisture at 40%-50%, and using the immersion pot method is safer than direct watering.
Special Condition Treatment Plan
Delay Sprouting Countermeasures
If no sprouting occurs within 45 days, gently scrape the epidermis to check the cambium layer: if it is green, continue to wait; if it is brown, check the roots. Combine with spraying芸苔素内酯 (2000-fold liquid) to promote germination.
Root Rot Treatment
If blackened roots are found, immediately soak them in potassium permanganate (1:800) for 30 minutes, then dry and repot using coarse sand. Maintain a ventilated environment and avoid direct sunlight.
By systematically mastering the growth patterns of pomegranate old stumps and the key points of repotting, combined with regular observation and care, even century-old stumps can be restored to a flourish of flowers and leaves. It is recommended to record growth milestones monthly and establish a dedicated care档案.
