Philodendron billietiae

Advice

1. Bright Indirect Light: Prefer bright but indirect light. Avoid direct sun exposure as this can damage the leaves.

2. Moderate Watering: Allow the top layer of soil to dry out before watering again. Avoid waterlogging.

3. Moderate Humidity: Although it can tolerate moderate humidity levels, it appreciates a more humid environment. You can increase humidity by placing a humidifier or by placing the pot on a tray of water.

4. Temperature Stable: Prefer warm temperatures between 18-24°C. Avoid cold draughts and sudden temperature changes.

5. Fertilisation: Feed with a balanced fertiliser during the growing season (spring and summer). Reduce fertilisation in autumn and winter.

6. Climbing Support: Since it is a climbing plant, provide a support such as a trellis or stake for it to cling to and climb.

Signs of weakness

1. Leaf Yellowing: Yellow leaves may indicate overwatering, lack of nutrients, or root problems.

2. Leaf Drop: Premature leaf drop may be due to sudden changes in environmental conditions, lack of light, or inadequate watering.

3. Leaf Spots: Brown spots or discoloration may be signs of watering problems, sunburn, or fungal diseases.

4. Brown Tips: Dry or brown leaf tips can be the result of low humidity levels, lack of water, or over-fertilisation.

5. Slow Growth: If the plant shows slow growth, it may need more light or nutrients.
