Requirements for Growing Geranium Indoors


Geraniums love the sun and don’t mind drenching in sunlight for long hours. Therefore, if your room has a South or West facing window, place them there.

Even when grown indoors geranium requires exposure to direct sun in order to thrive and bloom.

If you can’t keep the geranium near a sunny window use 40-watt supplemental fluorescent tube lighting fixed 12 inches over the plants for minimum 14 hours each day to help them growing.Soil

Don’t forget, the right soil is the key! Avoid soil that blocks the drainage holes. Use soilless potting mix. Don’t use garden soil, the texture of soil should be well-drained and loamy.


Here comes the most important part, proper watering ensures whether your geranium plant will live or die. As we know geranium is a drought-tolerant plant, it doesn’t require regular watering. Water only when the soil seems dry. Avoid overwatering!


Avoid placing your geranium plants in cold, hot or drafty spots. Geranium adjusts well to room temperature if it is warm. However, during the day the temperature around 65 to 70 F and around 55 F at night are optimum.

Indoor Geranium Plant Care


During the growing season fertilize every month using half strength all purpose liquid fertilizer for optimum growth. Instead, you can use slow release fertilizer as well.

Pinching and Pruning

To have a bushy, well-branched indoor geranium plant, remove the tips occasionally. Also, you can prune or cut the stems to get the desired shape.


As geraniums are not winter hardy it is important that you keep them away from drafts and too much cold. Also, watering must be reduced too!

Pests and Diseases

Overwatering can cause root rot, wetting the leaves while watering leads to fungal infection. In pests, mites, mealybugs, and aphids can be a problem.

Also, should I change the soil in the baskets in the winter?
I grow geraniums indoors every year in hanging baskets but I never got the nice & bushy. I also just brought in Martha Washington & they are very leggy. I don’t know how to pinch them back. They are getting so leggy,, they break. Then, I don’t know how to start the branches.
