Light Requirements

Moving your plant to a spot where it receives brighter lighting will help keep your Philodendron Prince of Orange happy and healthy.

Adding a blind or curtain to your window will help to defuse the harsh sunlight to avoid burning the plants foliage. Alternatively, if you can’t seem to find that perfect spot in your home, you can always use grow lights. Just like direct sunlight, if your plant is sitting too close to the grow lights, they will burn the foliage. Keeping a safe distance of at least 60cm between your plant and the light will avoid any trouble.

Philodendron Prince of Orange Watering Requirements

Depending on the temperature and humidity, you can expect your Philodendron Prince of Orange to require water around once a week. This plant likes the soil to be kept evenly moist.

Before watering, you should check the top 1-2 inches of soil with your finger to feel if the soil is still moist. If the soil feels dry, you should give your plant a drink. Drooping leaves can be a sign that your Philodendron Prince of Orange needs water.

Although this plant likes the soil to be evenly moist, it doesn’t like sitting in water and you should try to avoid over-watering. Excess water causes the soil to become waterlogged and can cause the roots to start rotting and not allow them to take in any water.

This can cause fungus issues, pest issues and root-rot. A sign that you might have over-watered your Philodendron Prince of Orange is yellowing and wilting leaves. Yellowing leaves, as well as brown and crispy leaf edges can be a sign of under-watering.

Fertilizing requirements

You should fertilize your Philodendron Prince of Orange monthly during Spring and Summer. You can cut down fertilizing to about every 6-8 weeks during the cooler months (Winter and Autumn) when the plant isn’t actively growing.

Fertilizing your plants helps to give them the essential nutrients they need for promoting and maintaining new and healthy growth. Applying fertilizer to plants while they’re not actively growing and using all the nutrients in the soil can cause salt built up and root burn.

The best fertilizer to use for Philodendron Prince of Orange would be a balanced all purpose fertilizer diluted to half strength. You can also create an organic fertilizer by adding things like leaf and bark matter, peat and organic manure to the soil. This acts as a slow release natural fertilizer, which will also help to lessen the chance of over-fertilizing.

When fertilizing your houseplants, you need to be cautious of over-fertilizing. A sign that you may have over-fertilized your Philodendron Prince of Orange is brown tips and curling leaves. If you think you have over-fertilised your plant you can either change the soil or rinse the fertilizer out of the soil. The water colour will change to clear once the fertilizer has been rinsed out.
