A healthy philodendron plant with green leaves
We’ve all been there before. We’re watering our seemingly healthy houseplant when suddenly there it is: a tinge of brown on the plant’s leaf. Yikes. But what do brown tips on leaves mean for your plant, and what can you do to make them go away? Read on to find out.
Lack of water or humidity
If your plant is sporting crispy, dark, or brown tips on its leaves, it may mean you need to water more often. Check the soil moisture and slowly reduce the number of days in between watering. Watch your plants for signs of improvement.
Lack of humidity could also be the cause. Tropical plants prefer higher humidity levels than we have in our homes. When we turn on the heat in winter, there’s even less moisture in the air. Group plants together so that as one loses moisture through its leaves, the neighbours benefit. Or place plants on saucers or trays filled with pebbles and water. Set a pot on the pebbles above the water. As the water evaporates, it will increase the humidity around the plant, where it is needed.

Lack of nutrients
A lack of key nutrients may be behind the brown tips on leaves of your plant. Burned-looking leaf tips, or old leaves with dark green or reddish-purplish colouring, may indicate a phosphorus deficiency. With a potassium deficiency, you may see yellow or brown along older leaf tips and edges, yellowing between veins, curling leaves, or spotting.
For potted plants, add a slow-release type of fertiliser to the soil mix before planting. Every time you water, a little fertiliser is released, providing a steady flow of nutrients. But depending on the growing conditions and number of plants in the container, a midseason boost may be needed. Stay on top of your fertiliser applications by making notes on a calendar.
