To increase humidity around your plant, consider placing it on a pebble tray filled with water, grouping it with other plants, or using a room humidifier. Regular misting of its leaves can also help, but make sure to use distilled or rainwater to prevent mineral buildup on the stunning foliage.

If humidity levels are not maintained, your Pastazanum may exhibit browning leaf tips, a common sign of low humidity.

Temperature Range

As a tropical species, the Philodendron Pastazanum enjoys a warm environment. It can tolerate a wide temperature range, but thrives best in the range of 65°F to 75°F (18°C to 24°C).

Keep in mind that this plant doesn’t handle cold very well. Sudden dips in temperature, especially below 55°F (12°C), may cause harm. Maintain a consistent temperature, avoiding drafts and sudden temperature changes to ensure optimal growth.

If you’re growing your Philodendron Pastazanum outdoors, make sure to bring it indoors if the weather turns chilly, as it is not frost-tolerant.

Remember, maintaining the right temperature is important for the overall health and well-being of your plant.

Soil Type & pH Preferences

The Philodendron Pastazanum prefers well-draining soil. This tropical favorite thrives best in a mixture of perlite, peat moss, and compost, but will also do well in regular houseplant soil that is kept moist but not waterlogged.

This soil balance supports the root health preventing root rot. Given its tropical origin, the Philodendron Pastazanum is adapted to slightly acidic soils.

Thus, a pH preference would be around 5.5 to 6.5, which is slightly on the acidic side. Ensuring the correct soil type and pH will help maintain the vibrant health of your Philodendron Pastazanum.

Growth & Propagation

Understanding the growth rate and propagation process is fundamental in providing ideal care for your Philodendron Pastazanum. Its growth pattern tends to be moderate, and it thrives most during the spring and summer seasons, making this the best time for propagation.

If properly cared for, this plant can reach impressive heights in the right conditions. Propagation is typically conducted through stem cuttings. Before you start the propagation process, it is essential to select a healthy parent plant.

Growth Rate

The Philodendron Pastazanum exhibits a moderate growth rate. While it’s not the fastest growing plant, it’s steadily producing new leaves, given the right care conditions.

Temperature, light, humidity, and care practices greatly affect the growth of this philodendron. Keep in mind, larger mature leaves take more time to develop than smaller juvenile leaves.
