FAQ:

Q: How often do you fertilize petunias?

A: Fertilize petunias once every three weeks. They like fertilizers that are balanced like 8-8-8 or 10-10-10. Before applying a liquid fertilizer make sure the plants are well watered. Never fertilize petunias that aren’t properly hydrated.

Q: When to water petunias?

A: Water petunias in the early morning hours when possible. This allows plenty of time for excess water to evaporate before the sun goes down. Watering in the morning also helps prevent the leaves and foliage from burning if they get wet during the watering process.

Q: When to plant petunias outdoors?

A: Petunias need to be started from seed around 10-12 weeks before you want to plant them outdoors. You should wait until after the last spring frost to move them outdoors. Knowing your frost dates can help you decide when to start your seeds indoors.

Q: When to fertilize Petunia seedlings?

A: Fertilize the petunia plants every two week with a liquid fertilizer diluted to half strength. Harden petunia plants after they are 3 to 4 inches in height by placing them outdoors for three to four hours a day for three days.
