It can be frustrating when you have put large amounts of effort into perfecting your garden, only to have some of the plants turn yellow or brown. One or two sickly plants can ruin the entire image of your garden. There are a few common causes of this and other ailments for philodendrons, which can easily be cleared up in a matter of days or weeks. By properly caring for your philodendrons, you can keep your plants looking healthy and beautiful.
Yellowing leaves on a philodendron are an indication that the plant is getting too much water. When watering, philodendrons should be kept moist, but not overly soaked. Avoid standing water, and allow the soil on and around the plant to become dry between watering.
Philodendrons with brown tips are not being given enough water. Maintain a regular watering schedule with your plants to avoid this occurrence. Ensure that your philodendrons are getting enough water that it can soak through the soil down to the roots.
Pale leaves on philodendrons indicate nutrient deficiencies. Different philodendrons have different requirements, so check with your local nursery for more information on your specific philodendron plant. Find out what the necessary soil pH levels are and ensure that your philodendron is in appropriate soil, as inappropriate pH levels can cause you philodendron to be unable to absorb nutrients from soil and fertilizer.
Brown patches on the leaves of your philodendrons are an indicator of too much sun exposure. If there is a way to reduce the plant's sun exposure in its current location, such as creating shade, pursue that. Otherwise, you may need to transplant the philodendron to another location.
Black patches on the philodendron's leaves indicate that the plant has been exposed to temperatures that are too low. While this may have been the result of abnormal temperatures for the season in your area, if you find it to be a regular occurrence, then you should consider plants other than philodendrons in the future, or look for a variety of philodendron that can survive in lower temperatures than the philodendron plant you currently have.
