The plant does not tolerate drought and should be watered regularly, but excessive watering can lead to the growth of root rot. Fertilizer should be applied every four to six weeks during the growing season to supplement the soil's nutrient content.
Cultivation Methods
Aporrhiza tessmannii Gilg ex Radlk. grows ideally in full sun but can also tolerate partially shady areas. It can also be grown in both acidic and alkaline soils, both of which require adequate drainage. Aporrhiza tessmannii Gilg ex Radlk. prefers a well-draining, sandy, loamy soil and can grow in a variety of soil pH. Adequate air circulation around the plant is necessary, as this plant is susceptible to fungal diseases.
Watering Needs
Aporrhiza tessmannii Gilg ex Radlk. requires regular watering to keep the soil moist. Too much water can lead to root rot, so it is essential to ensure that the soil drains well. In the hot season, the plant should be watered more often to prevent the soil from drying out. However, during the rainy seasons, the plant should not be overwatered as it can cause root rot. The watering needs of this plant will vary based on the temperature, humidity, and soil conditions.
Fertilization
Aporrhiza tessmannii Gilg ex Radlk. requires regular fertilization to promote healthy growth.
