CURLING LEAVES: Curling leaves are an indication that your plant is not receiving enough water. Ensure that you are watering once the top couple inches of soil have dried out, and avoid letting your plant sit in fully dry soil for too long.
BROWNING TIPS: Browning leaf tips can be a result of a couple of different things. Usually, it’s a result of your philodendron being exposed to overly dry conditions. Ensure that you don’t have an air vent blowing directly on the leaves, and consider providing your plant with extra humidity using a pebble tray or humidifier. Browning tips can also be a result of too much direct sunlight which has resulted in burnt leaves. Lastly, browning leaves can be a result of a lack of watering. Ensure that you don’t allow your Brasil to dry out too much between waterings.
