The Philodendron martianum does not like to be overwatered and so it is best to let the first 3cm of soil dry out before watering. In the cooler months when the plant goes into dormancy you will need to water less. The plant also likes medium humidity of around 60% and so in the drier months keep a tray of water nearby to assist with the humidity levels.
The plants benefit from regular fortnightly fertilising in summer and spring with a liquid fertiliser, and monthly fertilising during the dormant period of autumn and winter. To avoid root burn, ensure your soil is moist before fertilising.
Philodendron martianum grow in low light conditions and so do well as indoor plants. However, if you are looking to promote growth it is recommended that you give the plant access to filtered sunlight.
The Philodendron martianum is susceptible to root rot.
Symptoms include wilting or yellowing leaves. It is spread by a soil borne fungus
which may occur if the soil is too wet and not allowed to dry out between watering.
Conversely if you see leaves with brown edges, it is likely that you are underwatering
the plant.
Common pests include Mealy bugs and aphids, and it pays to inspect the plant
regularly. The best remedy is to use neem oil as required. The leaves benefit from periodic cleaning with lukewarm water which is preferable to leaf shine products.
