Why Does Corn Stone Keep Losing Leaves
As the 'gem' of the succulent plant world, Corn Stone is loved by plant enthusiasts for its crystal-clear leaves. However, many growers have noticed that this adorable plant often exhibits abnormal leaf shedding, with leaves falling like broken jade beads. What exactly causes Corn Stone to shed leaves frequently? And how should we care for it scientifically? This article uses three sets of real-shot comparison photos to delve into the truth behind Corn Stone's leaf shedding.
Three Main Causes of Corn Stone Leaf Shedding
Natural Metabolism and External Damage
Corn Stone belongs to a fast-metabolizing succulent variety, where leaves naturally shed every 3 months during the normal growth cycle. This physiological leaf shedding has distinct characteristics: leaves from the bottom begin to wither gradually, and new buds sprout after shedding. If the top new leaves are healthy and plump, just maintain normal care. It is particularly important to note: Corn Stone leaves contain 92% water content, so they should be avoided from touching or shaking the plant, as their fragile leaves are easily broken by external force.
Root Health Crisis
According to horticultural statistics, 68% of Corn Stone leaf shedding cases are caused by root problems. Overwatering can lead to root hypoxia and rot, which is manifested by sudden large-scale leaf shedding accompanied by transparency. Immediate action is required: remove the pot, cut off the blackened and soft-rotten roots, retain the white healthy roots, soak in carbendazim, and then replant in granular soil. Improper fertilization also harms the roots. It is recommended to use the '1/4 Concentration Rule' - dilute the fertilizer to 25% of the standard concentration and apply once every quarter.
Warning of Imbalanced Light Exposure
The intensity of light exposure is positively correlated with the plumpness of Corn Stone leaves. Experimental data shows that plants receiving 4-6 hours of scattered light daily have leaves 40% thicker than those in dark environments. Long-term lack of light leads to increased leaf spacing (etiolation), loss of green color, and eventually complete leaf shedding. It is recommended to place the plant on an east-facing windowsill in spring and autumn, use a shading net to filter strong midday sunlight in summer, and allow full sun exposure in winter. Within 2 weeks of supplemental lighting, the plant will gradually restore a compact growth habit.
Advanced Care Guide
In addition to the above three main causes, the following should also be noted: ① The substrate mix is recommended to be 70% granular soil + 30% nutrient soil; ② Maintain an ideal temperature range of 15-25°C, with winter temperatures not falling below 5°C; ③ When repotting in spring every year, trim dense branches to promote ventilation. Through systematic care, the lifespan of Corn Stone leaves can be extended to 9-12 months, truly achieving the ornamental effect of 'eternal jade leaves'.
By mastering these care tips, when Corn Stone shedding occurs again, you can accurately determine whether it is due to natural metabolism or improper care. It is recommended to establish a care log, recording watering times, fertilizer amounts, and other data, gradually exploring the care plan that best suits your own environment. Remember, the health status of succulent plants is often the cumulative reflection of care details.
