What are the cultivation methods and precautions for Philodendron 'Imperial Green' (Philodendron bipinnatifidum)?
1. Soil
Only fertile soil can meet the nutrient needs of the Philodendron 'Imperial Green' plant. It is best to use a loose, breathable sandy loam rich in humus. For potted plants, a culture soil made by mixing peat and perlite can generally be used.
2. Water
Philodendron 'Imperial Green' likes a warm and humid environment, and the soil should be kept moist regularly during the growing season. Its leaves are broad and thin, so it has a relatively high water demand, especially in summer when it must not lack water, but there should also be no waterlogging, otherwise its root system will rot and cause the plant to wither.
3. Light
Philodendron 'Imperial Green' is very shade-tolerant and does not have a great demand for light, but if it cannot receive light for a long time, its leaf color will become lighter and the leaves will wither, affecting its ornamental value. Therefore, during plant care, Philodendron 'Imperial Green' can be placed in a semi-shaded environment or one with sufficient scattered light for cultivation.
4. Fertilizing
Philodendron 'Imperial Green' is quite fond of fertilizer. During the peak growth period in summer, it can be fertilized 1-2 times per month. There is no need to apply too much fertilizer at one time; it is best to apply thin fertilizer more often. In other seasons, fertilizing should be reduced.
5. Pruning
After being kept for a period of time, Philodendron 'Imperial Green' generally begins to show phenomena such as yellowing, withering, and scorching of leaves. If this is not caused by disease, then the old leaves need to be cut off in time to avoid excessive loss of plant nutrients.
Cultivation methods for Philodendron 'Imperial Green'
Philodendron 'Imperial Green' is a relatively common indoor foliage plant. Its leaves are emerald green and broad, giving people a very lively and energetic feeling, and placing it in the home also has a good beautifying effect. So what are the cultivation methods and precautions for Philodendron 'Imperial Green'?
Philodendron 'Imperial Green' is not strict about soil requirements for cultivation. It is better to use a sandy loam rich in humus and with good drainage. For potting, a mixture of peat and perlite is generally used. Philodendron 'Imperial Green' likes fertilizer, and during the vigorous growth period it needs to be provided with sufficient fertilizer, preferably mainly nitrogen fertilizer. At the same time, note that too much fertilizer cannot be applied at one time; it is best to apply thin fertilizer frequently. Usually pay attention to the growth condition of Philodendron 'Imperial Green' and fertilize reasonably. If leaf yellowing is caused by fertilizer deficiency, nitrogen fertilizer should be supplemented in time.
After being cultivated for a period of time, Philodendron 'Imperial Green' will show yellowing and scorching leaves. At this time, if factors such as improper care or pests and diseases are ruled out, it can be determined to be normal metabolism of Philodendron 'Imperial Green', and the old leaves need to be pruned in time. When pruning, cut off the yellowed leaves and the overly dense and thin branches to reduce the loss of plant nutrients. When pruning, pay attention to choosing sharp tools to reduce wounds on the plant.
Philodendron 'Imperial Green' originates from tropical rainforests and has a relatively large demand for water. Generally, the air humidity should be maintained between 50-75%. Below 50%, leaves are prone to yellowing and dry edges. Air humidity can be increased by spraying water and sprinkling water.
Philodendron 'Imperial Green' originates from tropical rainforests and likes a humid environment. In addition, Philodendron 'Imperial Green' has broad leaves and a relatively high water requirement, so the potting soil should be kept moist during the growing period, especially during high-temperature summer periods when it must not lack water. However, do not water too much either. Water accumulation in the potting soil can easily cause the root system of Philodendron 'Imperial Green' to rot and the plant to die.
Cultivation methods for Philodendron 'Imperial Green'
Philodendron 'Imperial Green' is also called spring taro, split-leaf philodendron, tree philodendron, and little angel philodendron. It is a perennial evergreen herbaceous plant and is relatively shade-tolerant. The Philodendron 'Imperial Green' plant is lush, and its leaves are large and peculiar. The leaf color is emerald green and glossy, and its shade tolerance is relatively strong. It is currently one of the most commonly used indoor foliage plants in homes and public places. Generally, potted plants are placed in spacious places such as living rooms and lobbies, and small hydroponic plants can also be placed on desks, windowsills, and other places.
Philodendron 'Imperial Green' originates from the tropical rainforests of Brazil in South America. It likes a warm, humid, and semi-shaded environment. It is not strict about light, but it cannot tolerate long-term shaded environments, otherwise the leaf color becomes lighter, the petioles become longer, and the leaves droop, reducing its ornamental value. It is also afraid of direct strong light. After exposure to strong light, the leaves are very prone to dry leaf tips, scorched leaf margins, whitened leaf color, and loss of gloss, so it is best to maintain it with semi-shade or scattered light. In winter, sufficient light can be used for care so that it can overwinter safely.
The leaves of Philodendron 'Imperial Green' are large and thin, and it has relatively high water requirements. During the growth cycle, the potting soil needs to be kept moist, especially during high-temperature summer periods when it must not lack water. When the temperature is below 15°C, the frequency of watering needs to be reduced. The potting medium is commonly made by mixing leaf mold, peat soil, and river sand. Each time it is repotted, sufficient base fertilizer should be applied. The potting soil can simply alternate between dry and wet. It can tolerate brief waterlogging, but long-term water accumulation can easily rot the root system and cause the plant to die.
In late spring, Philodendron 'Imperial Green' enters its vigorous growth period and needs to be supplemented with fertilizer mainly based on nitrogen fertilizer to make it grow quickly and recover its vitality. Fertilization should be thin and frequent, and it should not be applied all at once in sufficient amount, which would cause fertilizer damage. If thin, mild fertilizer water can be used instead of clean water to irrigate the potting soil during the growth period, then growth will be even better.
After entering autumn, the application amount of nitrogen fertilizer should be controlled, otherwise it is not conducive to overwintering, the petioles will also become longer, and the plant shape cannot be effectively controlled. In winter, when the temperature is below 20°C, fertilization should be stopped.
Common diseases of Philodendron 'Imperial Green' include leaf spot disease, anthracnose, and so on. Wettable powders such as carbendazim, thiophanate-methyl, and zineb can be used for prevention and control, with obvious effects. If leaves are yellow, withered, or scorched, they need to be pruned in time to reduce the loss of nutrients. The main pests are red spider mites and scale insects. Special insecticides can be sprayed for prevention and control. In addition, red spider mites can be prevented by increasing air humidity, and scale insects can be prevented by strengthening ventilation.
