Philodendron "Red Congo"
PHILODENDRON RED CONGO
Native to South America.
Philodendrons do best in loose, well-drained soil that is high in organic matter. They will grow in 100% sphagnum peat moss. Soilless mixtures such as peat-vermiculite or peat-perlite are also satisfactory.
When growing philodendron plants, allow the top inch of soil to dry out between waterings. The length of your index finger to the first knuckle is about an inch, so inserting your finger into the soil is a good way to check the moisture level. Droopy leaves can mean that the plant is getting too much or not enough water. But the leaves recover quickly when you correct the watering schedule.
Set the Philodendron in a location with bright, indirect sunlight. Find a position near a window where the sun’s rays never actually touch the foliage. While it’s normal for older leaves to yellow, if this happens to several leaves at the same time, the plant may be getting too much light. On the other hand, if the stems are long and leggy with several inches between leaves, the plant probably isn’t getting enough light.
Feed philodendron houseplants with a balanced liquid foliage houseplant fertilizer that contains macro-nutrients. Water the plant with the fertilizer monthly in spring and summer and every six to eight weeks in fall and winter. Slow growth and small leaf size is the plant’s way of telling you that it isn’t getting enough fertilizer. Pale new leaves usually indicate that the plant isn’t getting enough calcium and magnesium, which are essential micro-nutrients for philodendrons.
The ideal temperature for a philodendron is between 65 – 78°F during the day, and around 60°F at night.
Philodendron should not be consumed by animals or humans. Lacy tree philodendrons are toxic to cats and dogs. Being educated on poisonous plants can help you avoid any accidents all the while enjoying your greenery.
Philodendron are not prone to insects, but you may encounter aphids and mealybugs. You can wipe off mealybugs with cotton balls dipped in rubbing alcohol. Periodically showering the plant with water and applying insecticidal soap will help keep pests at bay.
