About Growing Geraniums

Geraniums are among the most grown flowers in the United States, and indeed, around the world.

They require a location in your yard, garden, or home, that receives roughly 5 hours of light per day. That said, some species require more or less light.

Starting from seeds, geraniums take approximately four months to germinate. After germinating, the flowers require another three to four months to start blooming.

The species is self-pollinating as well, so they are excellent for indoor plants, and on porches, windowsills, and balconies.

Geraniums are flowering plants introduced to Europe by traders that brought them from South Africa. These plants resembled the wild European geraniums but they weren’t exactly alike.

There are two main kinds of geraniums, the annual plant which lasts only for a year, and the perennial which returns every season.

These gorgeous flowers are the perfect addition to every garden for their bright colorful flowers and their strong sweet scent.

Geraniums not only add color and fragrance to any garden but are also very easy to grow and take care of.

Find below the step-by-step guidelines for planting your own geraniums:

1. If you’re going to plant your geraniums outside, the first step will be to choose the right spot. Remember these plants grow better with at least five hours of sun per day.

2. No matter if you plant your geraniums in your garden or a pot, make sure the soil has good drainage. These plants do not like wet and soggy soil.

3. Geraniums grow better in soil that is loose. You can use a tiller to ensure that the soil is loose 12 to 15 inches down. 

4. Dig a hole for each plant making sure to leave a distance of at least 6 inches between them. 

5. Place the plant in the hole trying not to hurt the roots, which have to be level with the surface. Avoid putting soil in the stem of the plant as it may cause it to rot.

In autumn you can harvest the seeds that have appeared in your geraniums and save them for the following year. Read on below and learn about the process of harvesting geranium seeds. 

1. After the geraniums are finished blooming in early autumn, look for the seed pods that will start to develop at the base of the bloom.

2. Before harvesting the seeds, you’ll have to wait for them to turn brown and dry.

3. Cut the seed pods and store them in a paper bag for 2 weeks. Make sure the spot where you store them is warm and well-ventilated. 

4. Once the seeds are dry, separate them from the plant’s debris and store them in a paper envelope and inside a jar. Put two teaspoons of powdered milk in several layers of tissue inside the jar with the seeds.

5. Make sure the temperature of the storage spot is under 55 F and your seed will be ready to be planted the following spring.
