BROWN EDGES: Leaves with brown, crispy edges are an indication that your plant is not getting enough moisture. Try moving your plant to a more humid location and providing it with a good watering.
DROOPING LEAVES: If you notice that the leaves of your philodendron's leaves are drooping, it usually means that the plant needs to be watered. After a good watering, the leaves should perk back up within a few hours.
LEGGY GROWTH: Since this philodendron is a climbing plant, it can start to look leggy over time if it is not receiving enough light. When a plant is leggy, its leaves are spaced far apart along the stem and the plant can look like it is reaching towards the nearest light source. Once the plant has started to look leggy, there is no way to reverse that type of growth. However, you should move your plant to a brighter location to prevent future growth.
