The philodendron black cardinal is known for it’s dark almost burgundy colored leaves, which start off as red. It is a real show stopper with it’s dark leaves and a red fountain of new growth at the top. It is perfect for the inner goth in you!

Philodendron Black Cardinal Light Needs
Give it bright indirect sunlight. It will do well in a bit less light and further back from the window, but if it gets leggy, just move it forward. Be careful not to let it get direct sunlight at midday as it will burn the leaves.
How Often to Water
Check the plant once a week and water it if top inch or two (4cms or so) of soil is dry. Do not just water it on a schedule without checking it. These are easy to overwater and this can damage foliage or even root rot, so be careful and let it almost dry out.
Use a balanced fertilizer every two or three weeks in the summer growing months. It will really help the foliage to grow well. Do not use in winter or autumn when the plant grows a lot less.
Philodendron Black Cardinal Soil
For a philodendron black cardinal you definitely want to make sure the soil is well draining as they can be susceptible to root rot. Make sure it is loose too, they do not like packed wet soil. They really want plenty of perlite added, some people use a cactus and succulent compost.
When To Repot
If you see roots growing through the bottom of the pot you can repot the plant up a pot size. You can do this any time of year, but the best time is in Spring.
Philodendrons like 50% humidity which is the higher end of household humidity (most households are 30-50%). Give them a misting two or thee times a week. Misting is good as it helps to keep the plants leaves clean from pests, at least at the early stages, it also removes dust which can inhibit photosynthesis. Just be careful with mold.
Philodendrons like this do well in the 16-28°C (61-82°F) range. Normal household temperature is 20°C to 25°C (68-77°F), so these plants will do well in most households. Just don’t let them get too cold in the winter, keep away from draughts.
Philodendron Black Cardinal Propagation
The black cardinal is an easy to propagate plant, you just need to take stem cuttings. Just be careful as the stems are very close together is it is self-heading compact-growing plant. Let the cuttings callous over for an hour or two and then root them in water or moist sphagnum moss. Keep it humid and in indirect sunlight and it should root over the next month or two. Then you can pot it up into soil and it you should see new stem growth soon.
When a I propagate a self heading plant like this I wait until it is a large plant and then cut it right down, taking a lot of stem cuttings and making quite a few new plants. Cutting a self heading plant like this will change its shape, so I tend to go big and really cut it down.
