Philodendron Verrucosum Incensi. A rather handsome, and unusual hemiepiphytic climbing vine that naturally starts life growing in the canopy of trees, epiphytically, but eventually will reach the soil with its roots. The boldly patterned, heart shaped leaves are quite spectacular. Native to the rainforests of Central and South America they are another highly desirable, and often difficult plant to find, so if you need one of these in your plant collection then grab one while available.
As with most sub–tropical jungle plants Philodendron thrive in bright, indirect light, this mimics sun light through the jungle canopy. They will adapt to semi-shade but growth will be slightly slower. Must avoid direct Summer sun as the leaves will scorch.
From Spring until late Summer water thoroughly, about once a week, then allow the top couple inches of compost to dry out before watering again. If kept in shade it may take a little longer to dry, so don`t be hasty, it`s best to be a little cautious to avoid overwatering. If possible use rainwater, or tap water that has been allowed to stand for 24 hours.
Room temperatures between 18-25c are fine.
Fertilise regularly through Spring and Summer , once every 2-3 weeks, with a half strength balanced liquid feed.
During the colder months in heated rooms increase the humidity around your plant. Group together with other plants, stand on a tray of moist gravel, or occasional misting will increase the moisture in the air around your plant.
Allow to grow until it reaches the maximum size that space allows, you can then prune them to remain that size.
Make the most of the plant by keeping the leaves clean and dust free by wiping with a soft damp cloth.
Minimum Temp: 16c
In Winter, when temperatures are cooler and growth is slow, reduce the amount and frequency of water, and do not fertilise. Make sure to allow the top 1/3rd of the compost to become dry between watering, again this may take a little while, so don`t be hasty, most problems arise from over watering.
Re-pot in Spring once the roots have filled the current size pot, approx. every 2 years. Only use a slightly larger pot and good quality free draining compost, a big pot with too much compost will hold too much water.
Common leaf problems are brown tips indicating dry air, or yellow leaves too much water.
Warnings: The plant contains raphides, crystals of calcium oxalate, to deter livestock from eating them. Therefore problematic to pets and humans if consumed. Causes irritation and swelling in the mouth. Best practice is to keep out of reach.
