Geraniums are a popular choice for gardeners everywhere. They’re easy to grow, require minimal maintenance and produce beautiful flowers in a variety of colors. However, it can be difficult to know how much space to leave between each plant when planting geraniums. In this article, we’ll discuss the factors that affect the spacing of geranium plants and provide some guidance on how much space to leave between them.

Factors That Affect Geranium Plant Spacing

Several factors influence how much space you should leave between each geranium plant in your garden. These include:

1. The Variety of Geranium

The variety of geranium you choose will determine how large the plant grows and how much space it needs. For example, ivy geraniums tend to spread out more than zonal geraniums, so they require more space between plants.

2. The Size of the Container or Bed

If you’re planting geraniums in a container or bed, the size of the container or bed will also determine how much space to leave between plants. Larger containers or beds can accommodate more plants spaced further apart, while smaller containers or beds require plants to be closer together.

3. The Growing Conditions

The growing conditions for your geraniums will also affect how much space to leave between them. If your plants are going to be in full sun, they may need more space between them than if they’re going to be in partial shade.

How Much Space Should You Leave Between Geranium Plants?

As a general rule, you should leave between 8 and 12 inches of space between each geranium plant. This spacing allows the plants to grow and spread out while still providing enough room for air circulation and sunlight exposure.

However, if you’re planting ivy geraniums or other varieties that tend to spread out more, you may need to leave up to 18 inches of space between plants. On the other hand, if you’re planting zonal geraniums or other varieties that grow more upright, you may be able to get away with leaving just 6 inches of space between plants.

Tips for Planting Geraniums

Here are a few tips to keep in mind when planting geraniums:

  • Make sure the soil is well-draining and nutrient-rich.
  • Water your geraniums regularly, but avoid overwatering.
  • Mulch around your plants to help retain moisture and regulate soil temperature.
  • Deadhead your geraniums regularly to promote new growth and blooming.
  • Fertilize your plants once a month during the growing season.
