Caudex Plant Seasonal Growth Calendar — Year-Round Watering and Care Schedule

Caudex plants have different growth patterns depending on the species, and providing appropriate care for each season is key to maintaining healthy plants. They can be broadly divided into summer-growing and winter-growing types, each requiring different watering and placement management. This article explains year-round care schedules broken down by season.

Spring (March-May) Care

Spring is the most important period for summer-growing caudex plants. When temperatures begin to exceed 15°C, summer-growing species such as Pachypodium, Adenium, and Operculicarya awaken from dormancy. Once new growth begins, resume watering with small amounts. Giving too much water at once can cause roots to fail and lead to rot. Repotting is best done right after new growth begins. Clean up the roots and replace with fresh soil, then refrain from watering for one week after repotting. For fertilizing, once growth picks up from April to May, begin applying diluted liquid fertilizer about twice a month. For winter-growing species like Adenia glauca and Dioscorea elephantipes, once leaves begin to turn yellow, gradually reduce watering and prepare for dormancy.

Summer (June-August) Care

Summer is the peak growing season for summer-growing species. Provide plenty of sunlight and water to encourage vigorous growth. Water thoroughly when the soil is dry, aiming for once or twice per week. However, during the rainy season, be careful of excessive moisture from prolonged rain—if rain continues, move plants under shelter. During intense summer heat, pots can become very hot, so avoid placing them directly on concrete. Instead, use shelves or stands to lift them off the ground and ensure good air circulation. Continue applying diluted liquid fertilizer about twice a month. Winter-growing species are in complete dormancy, so withhold water entirely and keep them in a cool, shaded place. Ensure only adequate air circulation and prevent humidity buildup.

Autumn (September-November) Care

Autumn is when the growth of summer-growing species begins to slow gradually. September still has many hot days, so continue normal watering, but once October arrives and minimum temperatures begin to drop below 15°C, gradually reduce watering frequency. For plants that have begun to drop leaves, reduce watering even further. Cease fertilizing by the end of September. Applying too much fertilizer before dormancy can cause new growth that will be vulnerable to winter damage. Meanwhile, winter-growing species like Adenia glauca and Dioscorea elephantipes begin to awaken in autumn. Once new growth is visible, gradually resume watering and move plants to a well-lit location. September to October is the ideal time to repot winter-growing species.

Winter (December-February) Care

Winter is the dormancy period for summer-growing species. For plants that have completely dropped their leaves, withhold water entirely and keep them indoors at a minimum temperature of 10°C or above. For cold-sensitive species like Pachypodium, 15°C or above is safer. Even for plants that have not dropped all leaves, limit watering to very small amounts about once a month. If using a heating mat, maintain the root zone temperature around 15-20°C. Winter-growing species should be managed normally in a bright indoor location, with watering when the soil is dry. Since heated rooms tend to be dry, observe the condition of the leaves and adjust watering frequency accordingly.
