What Kind Of Light Do Geraniums Need – Light is one of the most important factors for the growth of houseplants. All plants require light for photosynthesis, the process within a plant that converts light, oxygen and water into carbohydrates (energy).

Plants require this energy to grow, flower and produce seed. Without adequate light, carbohydrates cannot be processed, energy reserves are depleted and plants die.

These plants grow well indoors in well-lit areas, such as in eastern windows or close to a western window, but out of direct sunlight. You will often find central plants in spaces where fluorescent lights are used every day as a building function.

Areas of high light are brightly lit areas, such as south-facing or south-facing windows. As a rule of thumb, most plants grown for their flowers require high light growing conditions.

The distance between the light source and the plant concentrates the light.

While there are many ways to measure light, a few common measurements you’ll see include;

. When it was later discovered that these new “geraniums” differed from European geraniums in the shape of their petals, the number of stamens and other features, they were reclassified.

However, their original common name has stuck, and we still say “geranium” when we mean “pelargonium.” Pelargonium is perhaps difficult to say! This word is pronounced, “Pel-ar-GO-genu-um.”
