It is important to keep them properly spaced in order to allow for good air circulation and prevent disease.
Additionally, if you are planting multiple rows of petunias, they should be spaced 3 to 4 feet apart.
Why Spacing Matters When Planting Petunias
When it comes to planting petunias, the spacing between individual plants is of utmost importance.
By ensuring the proper spacing between the petunias, gardeners can maximize the health and vibrancy of their plants.
Different petunia varieties require different spacing, so its important to consider the variety before planting.
The larger Grandiflora varieties of petunia require more space between plants, with a recommended spacing of 18 inches.
This is because the larger plants need more room to spread out and grow, and can become overcrowded if planted too close together.
On the other hand, smaller varieties such as Multifloras only require 12 inches of space between plants.
In addition to the spacing between plants, its also important to consider the location of the petunia plants.
Petunias require full sun for at least six hours a day in order to thrive and be healthy.
If planted in an area that receives too little sunlight, the petunias may struggle to grow and produce vibrant blooms.
To ensure the petunias look their best, make sure they are planted in a location that receives plenty of sunlight.
By following these guidelines, gardeners can ensure their petunias are planted at the right spacing and in the right location for the best results.
By taking the time to consider the spacing and location of petunias, gardeners can maximize the health and vibrancy of their plants.
