Glottiphyllum longum is a species of succulent plant in the family Aizoaceae, native to the Western Cape and Eastern Cape Provinces, South Africa. It is the most widespread Glottiphyllum species, and the most common one in cultivation.
Long Tonguefig has moderate disease resistance and is relatively sensitive to humidity. It is vulnerable to disease in high-humidity conditions and tends to develop root rot during dormancy. Regarding care, Long Tonguefig is drought-tolerant but requires more water in the growing season. Watering should be greatly reduced or stopped entirely during the dormant period. Long Tonguefig is suited to growers with some experience, though it can be challenging to care for, especially during dormancy. It is particularly suited to people who can devote time to its care during the winter months.
How to keep Glottiphyllum Longum.
Light
Originating from arid areas, the Long Tonguefig performs best in full sun, as its native habitat has intense sunlight and very little shade. It can also tolerate partial sun, giving it some flexibility in its growth.
Water
Glottiphyllum longum thrives in arid environments due to its ability to retain moisture in its succulent leaves. It is drought-tolerant and requires minimal watering, typically only once every three weeks. When grown outdoors, it benefits from natural rainfall and needs even less water during its dormant period. This plant adapts well to low-humidity conditions.
Temperature
Although Long Tonguefig tolerates some heat, it mainly thrives and grows in cooler seasons and goes dormant during summer. In very hot summer conditions, provide shade to prevent scorching from intense sunlight. Watering should be reduced or stopped during the hottest part of the year to avoid root rot. Long Tonguefig grows vigorously in winter and spring. If temperatures do not fall too low, it will continue to grow steadily.
Fertilizer
For Long Tonguefig, light applications of fertilizer once or twice a year during the growing season are enough. Avoid fertilizing in winter and in summer, when the plant is dormant. Cut back on fertilizer for plants that have been repotted, and wait a couple of months after repotting before you fertilize. Fertilizing helps maintain healthy growth and encourages blooms.
Pruning
To keep your Glottiphyllum longum in good shape, regular pruning is essential. Focus on removing dense or unnecessary branches, especially during spring and autumn. For propagation, cut healthy stems with 5 to 6 leaves. Treat the cut ends with sulfur powder to prevent infection and allow them to heal before planting. Make sure to moisten the soil during this process for the best results.
Pot & Repot
When repotting Long Tonguefig, choose a pot slightly larger than the current one that has good drainage. Use a gritty, well-draining cactus or succulent mix. Gently remove the plant from its old pot, brush off excess soil, and plant it at the same depth. Wait a few days before watering to let any root damage heal. Repot in spring or fall and place it in a brightly lit location.
