Essential care for Jatropha podagrica
Jatropha podagrica is a hardy and easy-to-maintain plant, but it is important to follow certain recommendations to ensure its optimal development and flowering.
- Light: It needs plenty of natural light, so it is ideal to place it near a well-lit window or on a sunny terrace, but avoiding direct exposure to the sun during the hottest hours, as it can cause leaf burns.
- Temperature: It prefers warm environments, with temperatures between 18 and 24 ° C during the growing season. During the winter dormancy, it is advisable that the temperature does not drop below 12°C. It does not tolerate frost.
- Humidity: Although it tolerates dry environments, a lack of light or excessively dry conditions can cause leaf drop. Moderate humidity will help keep the foliage healthy.
During the winter the plant enters vegetative rest and may lose some of its leaves. This process is normal and part of its annual cycle.
Soil, substrate and transplant
El ideal substrate must be very draining to prevent waterlogging, which can cause root rot. A recommended mix includes:
- 2 parts of gross sand or perlite (for excellent drainage)
- 1 part of leaf mulch
- 1 part of peat
- Optionally add 25% of fine gravel to further improve the structure
Jatropha must transplant every two years, preferably in spring, always choosing a deep pot that can accommodate its thick, fleshy roots.

- In winter: Stop watering completely, as the plant needs a marked vegetative pause, and excess water at this time is the main cause of root rot.
Never flood the pot and ensure drainage is effective. A saucer under the pot can retain water and should be emptied after each watering.
La fertilization takes place in spring and summer Using a specific liquid fertilizer for cacti or succulents, applied once a month. This will promote flowering and plant vigor.

Multiplication and propagation
The propagation of Jatropha podagrica is possible by seeds o apical cuttings:
- By seeds: They are sown in spring in a seedbed at a constant temperature of 24°C. Germination is easy if adequate humidity is maintained.
- By cuttings: The apical cuttings should be taken in mid-spring. It is important to be careful with the irritating white latex produced by the plant (toxic in contact with eyes or mucous membranes). The cuttings are soaked in water to stop the latex from bleeding and then left to dry for one or two days before being planted in a mixture of peat and coarse sand.
Rooting is usually rapid if warm conditions are maintained and the substrate is slightly moist, not wet.
