Why Are My Plants Stretching?

January 5, 2019

When plants stretch or grow toward the sun, also known as tropism, they are reaching for more blue light. When sun-loving plants grow in too much shade, their growth slows down and their internode length elongates.

This arrowhead plant, which sits about 5 feet away from a bright north-facing window, is still stretching to reach more light.

The plants stretch to avoid the shade so they can compete with surrounding plants and reach more light.
