How to Take Care of Geraniums in the House

Overview

There is nothing quite as vibrant and earthy as the array of assorted colors and distinct musky fragrance provided by indoor potted geraniums. The multiple clusters of fire engine red, pure white, soft pink and deep purple petals brighten up any room with a window. Indoor geraniums are a hardy selection for home or office environments, requiring only ample sunlight and a minimal amount of care to ensure budding brilliance throughout the season.

Step 1

Maintain geraniums in containers with proper drainage holes. Fill containers with a quality potting soil mixture high in nutrients to stimulate growth. When plants begin to outgrow the container, replant into a larger container to accommodate the root structure and provide proper soil aeration.

Step 2

Place geraniums in an area where the plants will receive at least eight hours of full sunlight. Use fluorescent lights during the evening for several hours as an option in rooms that do not provide adequate sunlight during the day.

Step 3

Check the moisture of the soil periodically between weekly waterings. Geraniums do best in either slightly dry or moist soil. Overly saturated soil and plants left sitting in water dishes will result in root rot.

Step 4

Fertilize indoor plants once in the warmer months of March through August and twice a month in the cooler months of September through February.

Step 5

Prune the tips of the stems to regulate the height of the plant. Reducing the height forces growth to develop more branches, resulting in a fuller plant.

Step 6

Inspect plants for diseases and pests. Use an eco-friendly insecticide spray to dispel common pests such as aphids and mites. Use fungicidal sprays and dusts or manually remove infected leaves and stems affected by leaf spot, rust, discolored leaves or mold.

Tips and Warnings

  • Do not place geraniums in direct proximity to air conditioning vents, heaters or fireplaces as too much cold or heat affects the health of the plant.
