How to Grow Philodendron selloum: Cultivation Methods and Precautions

Most plants are named according to their form and appearance, and Philodendron selloum (tree philodendron) is a green plant whose appearance resembles feathers. It is usually planted in some public places, because Philodendron selloum is a relatively large plant, so the space where it is usually placed needs to be relatively large.

How to Grow Philodendron selloum

Philodendron selloum likes a hot and humid growing environment, has low requirements for light, and has strong shade tolerance. Philodendron selloum is relatively intolerant of cold; the suitable temperature for growth is between 18℃——25℃, and the wintering temperature in winter must not be lower than 5℃. Philodendron selloum likes loose, fertile sandy soil with good drainage.

Cultivation Methods and Precautions for Philodendron selloum

1. Soil

As far as the habits of Philodendron selloum are concerned, Philodendron selloum likes fertile, loose, well-drained slightly acidic soil, so its requirements for soil are relatively low. For home cultivation of Philodendron selloum, you can use a mixture of leaf mold, peat soil and a small amount of river sand from the garden.

2. Watering

Philodendron selloum likes a relatively humid environment and has a relatively large water requirement, but it does not have high requirements for water, so you can usually water it with rice-washing water. Note that during the growing period, keep the soil moist. It should be noted that the amount of watering needs to change in degree according to the season. In summer, spray water on the leaves and around them more often to maintain a humid environment; in winter, the frequency of watering should be reduced.

3. Fertilizing

Philodendron selloum has strong adaptability, and whether in a humid environment or dry conditions, it can adapt as quickly as possible. Therefore, its demand for fertilizer is also not high. When potting, place some hoof and horn pieces or oil residue at the bottom. After that, only apply liquid fertilizer once a month, such as thin cake fertilizer water. Pay special attention to applying less or no fertilizer in winter to meet the needs of the plant.

4. Light and Temperature

Philodendron selloum likes warmth and tolerates shade but is not cold-tolerant and fears light; it avoids strong light exposure, and the suitable temperature is 18°-25°. Therefore, in summer, Philodendron selloum needs to be moved to a shady place to avoid direct sunlight, and in winter it can be moved to a place with sufficient light, so that its wintering temperature is greater than 8° as much as possible. 5. Pests and Diseases

Common diseases of Philodendron selloum include leaf spot disease, anthracnose, etc., which can be prevented and controlled with chemicals such as carbendazim and thiophanate-methyl. If problems such as yellowing and withering of leaves occur, pruning is needed. Common insect pests of Philodendron selloum include red spider mites and scale insects, which can be prevented and controlled with special chemicals. In addition, more ventilation is needed to prevent insect pests.

6. Propagation

Keep the temperature at a fixed value of around 20°, avoiding an air environment that is too hot or too cold; keep humidity at a high value, spraying and sprinkling water more often to increase environmental humidity; keep light and temperature at normal values, avoiding too high or too low; the fertilizing principle is “apply thin fertilizer frequently” and mainly nitrogen fertilizer; watering frequency is high, and in summer it is necessary to ensure it stays moist at all times, while in winter it is necessary to water alternately dry and wet.

How Philodendron selloum Overwinters

1. Control of Room Temperature

To be safe, eight degrees and above can allow it to safely pass the winter, and it is best not to be lower than zero degrees Celsius at the lowest. Although the plant may also be able to endure it and slowly recover in the following spring, we still should not joke around with our beloved plants.

2. Control of Moisture

We may all have heard that the place of origin of Philodendron selloum is a hot and humid place, so its demand for water is relatively large. Although it begins to go dormant in winter and the water it needs decreases accordingly, you still cannot forget to water it. Water promptly when the potting soil becomes dry and cracked, but do not let it soak in water. In addition, you can also care for it by sprinkling water on the leaves and spraying water into the surrounding environment.

3. Control of Light

If it is placed in a dark place for a long time, its leaves may slowly turn yellow, and its beautiful green color will gradually disappear. Therefore, let it see light regularly. However, it also does not like long-term light. That's right, it is a bit demanding. So, choose a semi-shaded environment, or let it bask in the sun for a while and then promptly take it back.

4. Control of Fertilizer

From late autumn, pay attention to the amount used. In winter it will enter the dormant period and hardly needs nutrients, so fertilizing should be suspended.

Solutions for Rotten Leaves of Philodendron selloum

If rot has already appeared, when the situation is not serious, pruning can be carried out accordingly; if it is due to excessive water or improper fertilizing, then the soil needs to be changed and it needs to be replanted.

Before planting the plant, you must choose soil with relatively good water permeability and air permeability, so that even if you occasionally water too much, it will drain out easily.

During daily watering, do not pour it all in at once; you can pour it in slowly, and when watering you can gauge the amount of water by seeing how much water is poured in before water comes out of the drainage holes at the bottom, and then make a record, so that future watering will have a comparison. When the temperature drops to 15 degrees, you must control watering, as at this time the plant's demand for water gradually weakens.

When fertilizing normally, be sure to pay attention to the concentration of the fertilizer, dilute relatively concentrated fertilizer, and slowly apply it along the edge of the pot.

Try to choose a place with relatively good air circulation for care.

The important thing in growing plants is to create an appropriate growing environment according to the plant's normal growth needs, while paying attention to some important growth stages of the plant, such as flowering, propagation, overwintering and getting through summer, and often paying attention to the plant's growth state to deal with corresponding pests, diseases and special symptoms.
