CARE GUIDE

How to keep Tetranema Roseum.

Light

Mexican foxglove comes from habitats with dappled light, such as forest understories or rocky locations that offer natural shade. It does best in partial sun but can also tolerate full sun.

Temperature

Mexican foxglove comes from tropical areas, where the weather is generally warm and humid. Consequently, it is adapted to high heat and humidity. It does not tolerate sudden temperature shifts and prefers a consistent temperature, so avoiding indoor temperature fluctuations is important. It normally cannot endure cold conditions and needs warmer temperatures to grow. If the ambient temperature falls too much, the plant may stop growing or even die.

Fertilizer

When most of the Mexican foxglove's blooms have opened to full size, resume fertilizing. During the period of peak flowering, apply fertilizer every three to four weeks, weather permitting. After the plant begins to produce fewer new blooms, stop fertilizing — there's no need to feed it when it can no longer produce more flowers.

Pruning

To encourage growth and flowering, prune Mexican foxglove from early to late spring. Start by removing dead stems and lightly trim overgrown areas just above a leaf node. This helps improve air circulation and reduce the risk of disease. Always use clean, sharp tools to ensure the plant's optimal health.
