In most plants, variegation is supported by light. Variegation - If your plant exhibits variegated leaf patterns that begin to disappear over time, you need to increase light levels. You can always start with our basic care suggestions, online research and light meters to find a location for your newest plant, but if you are still unsure that your plant is getting the right amount of sunlight, there are a few plant signals to watch out for:
The best way to check light levels is to download a free light meter app on your phone and check up on plant species light requirements. Most interior environments provide much less light than you would think.
Because of their genetic make-up, different plants handle different light levels. While some plants can acclimate to higher light levels with time, there is a limit to how much an individual plant species can handle. Because of that fact, moving a plant from inside to outside (or outside-in) can shock its leaves and cause sun scorch. They acclimate to their environment’s lighting by producing leaves optimized to take in the amount of light provided. Different from human eyes that adjust quickly to varying light levels, plants are incapable of the quick switch from dim to bright lighting.Īlthough most don't realize it, plants change their growth to favor current growing conditions. Even though plants don’t have eyes, they do perceive light! They sense light quality (color), light quantity (intensity) and light duration (time). Have you ever walked into a house after being outside on a bright, sunny July afternoon? What could you see? Darkness, right? Our sophisticated human eyes are capable of adjusting to dim lighting in just seconds. Before we explore how to know if your houseplant is getting enough light, let’s talk about how plants perceive light.
