Rejuvenation of Persimmon Trees: When a 70-Year-Old Plant Returns to Productivity with Modern Techniques

In a marginal and poorly managed
setting, an old persimmon tree was observed, characterized by a rough bark and
a large trunk diameter (30–35 cm), a clear indicator of a plant over 60–70
years of age. An imposing structure, seemingly destined for removal, which
instead proved to be an extraordinary technical opportunity.
Initially considered unproductive
and slated for elimination, the tree underwent a drastic reform intervention,
comparable to a controlled topping. The cut, performed at a height between
approximately 90 and 110 cm, stimulated a vigorous emergence of shoots and
suckers along the trunk. This is the most delicate phase: without proper
technical management, the plant tends toward vegetative disorder. With correct
guidance, however, a new architecture can be established.
Through the application of the
principles of the Mataix system, the most vigorous shoots were selected and
progressively transformed into productive branches. Only a few main axes
(leaders) were retained, on which to build a balanced, well aerated canopy
suited for production. Branches that were initially purely vegetative were
guided toward fruiting, promoting an even distribution of light and more
efficient plant management.
The result is a completely
rejuvenated tree, structured according to modern criteria, despite originating
from a very old framework. This case clearly demonstrates how persimmon is a
species endowed with high resilience and longevity. Despite its relatively soft
wood, it is capable of responding vigorously even to drastic interventions,
ensuring a strong and lasting recovery.
Similar experiences have also
been documented in Spain on varieties such as Rojo Brillante, where mature
trees (30–35 years old) are cut back almost to ground level to be fully renewed
and reintegrated into modern management systems.
An additional technical aspect
concerns the rootstock Diospyros lotus, widely used in older orchards.
It is distinguished by its ability to produce suckers even at a distance from
the mother plant and by the production of small fruits, sometimes useful for
pollination. Its presence is often indicative of the age of the orchard and of
the nursery techniques employed in the past.
Overall, this experience
highlights a fundamental principle: an old tree is not necessarily a finished
tree. When properly managed, it can be recovered, restructured, and restored to
full productive efficiency. Rejuvenation is not merely an agronomic intervention,
but a true strategy for enhancing the value of existing plant capital.
