How to Grow Red Geraniums


The red geranium is an annual flower, but it can survive year-round if brought indoors during the winter. It is a popular window box flower and grows easily in pots or in the ground. It requires a minimum of four hours of sunlight a day, but in very warm climates, it benefits from shade during the hottest hours of the day. Regular pruning of your geranium will keep it bushy and blooming.

Step 1

Plant the geranium in potting soil either directly in the ground or in a container and water thoroughly. If using a container, make sure it drains well.

Step 2

Place the geranium in a spot that receives at least four hours of sun a day.

Step 3

Water when the soil appears dry but avoid over-watering or you risk causing bacterial leaf diseases. Most geranium varieties are drought tolerant.

Step 4

Regularly remove any yellowing or dead leaves from the plant.

Step 5

Remove blooms when you see them start to fade; this will encourage new blooms to form.

Step 6

Trim the red geranium once a year in the fall by cutting back approximately one third of each stem above the juncture where a leaf forms.

Step 7

Bring the red geranium indoors before the first frost. You can keep the geranium in a pot in a sunny window all winter or let it go to sleep for a few months in a cool, dark spot, such as your basement, where the temperature remains above 45 degrees F.

Step 8

Place the red geranium back outside in spring after threat of frost has passed and water regularly.

Tips and Warnings

  • Avoid planting the geranium too deep in the soil or the stem may rot. The soil should be even with the top of the root system. A little mulch on top of the soil is okay, but don't pack it in too close to the stem.
