Growing of Petunia :
Petunias are one of the most popular flowers, often grown as annuals. They are tender perennials in Zones 9 to 11.
Four species of petunias include hundreds of cultivars and offer a perfect addition to the home landscape:
- Grandiflora petunias is the most common type of growing petunias. This species features 3 to 4 inch blooms which often grow upright, but may spill over the side of your container or window box.
- Multiflora petunias have smaller flowers and a more abundant bloom.
- Milliflora petunias are miniature versions of growing petunias, compact and reblooming.
- Spreading petunias are only 6 inches tall and can rapidly cover a selected area to function as a blooming ground cover.
- you can grow petunias from seeds, but it is easier to grow them from transplants. If you are going to grow from seeds, start them indoors 10 to 12 weeks before you want to set them outside. Petunia seeds are very small and needs lots of light in order to germinate. Remember to water them. When the plants have three leaves, you can plant them outside.
- It’s best to buy transplants and plant them in light, well-drained soil in full sun after the last spring frost. Petunias can grow in partial shade, but they will have fewer flowers. It’s better if the plants have shelter from the wind.
- Space the plants about 1 foot apart.
- If you’re planting petunias in containers, use a soil-less mix.
Care of Petunias:
Care of petunias includes regular watering and as much sunlight as possible to promote multiple blooms. Spreading ground cover petunias are pickiest about water, weekly waterings should be included in the care of petunias.
While petunias will grow in a partially shaded location, a fuller and more abundant bloom is produced in full sun. Soil prepared before planting petunias should have well-composted organic matter worked in.
Care of petunias will include regular fertilization with a balanced, water soluble fertilizer designed for blooming plants. As they are heavy feeders, petunias care will also include weekly feedings. Proper light, water and fertilization when caring for petunias will ensure a long season of beautiful blooms.
Proper petunia care involves removing spent blooms and the seeds they may produce. When deadheading the growing petunias, remove the base of the flower to include seed removal. Petunias allowed to go to seed will slow or stop blooming.
