Watering houseplants with brown tips of leaves can be tricky business, since the most common causes of brown leaves on houseplants are over and under watering. Follow these tips to tell what's going on with your plants and how to give them the water they need in order to thrive.
Phototropism (growing towards light) occurs because the tips of growing plant shoots contain a pigment that's sensitive to light, especially blue light. When light shines on the shoot, it gets absorbed by the pigment (called phototropin), and that triggers the release of the plant hormone auxin, which makes cells grow. The direction of the light determines where the auxin acts. If light is coming from the right, auxin gets sent down the left (shady) side of the shoot. That makes the cells on the shady side grow longer, putting a kink in the shoot so it points to the light.
