Bladverkleuring

Bladverkleuring refers to the change in color of plant leaves. This phenomenon is a natural part of the plant life cycle and can be caused by several factors. The most common cause is the onset of autumn in temperate climates, where the decline in daylight hours and cooler temperatures trigger the breakdown of chlorophyll, the green pigment responsible for photosynthesis. As chlorophyll degrades, other pigments like carotenoids (yellows and oranges) and anthocyanins (reds and purples) become visible, leading to the vibrant fall foliage.

Beyond seasonal changes, bladverkleuring can also indicate stress or disease. Nutrient deficiencies can manifest as yellowing (chlorosis), often between the veins, or purplish hues. Insufficient light can also lead to a paler green or yellowing. Conversely, overwatering can cause leaves to turn yellow or brown, sometimes accompanied by wilting. Fungal or bacterial infections can result in spots, streaks, or widespread discoloration of leaves, often with distinct patterns depending on the pathogen. Pests can also damage leaf tissue, leading to stippling, bronzing, or yellowing. Understanding the specific pattern and context of bladverkleuring is crucial for diagnosing the underlying cause.
