The Q&A Archives: Keeping Pansies and Petunias Blooming

Question: How can I keep pansies and petunias in bloom all summer besides pinching them back? What's the lowest temperature they can stand?

Answer: Pansies are cool weather plants, so they will bloom in the spring until the weather heats up. If you can keep them alive through the summer, they should rebloom in the fall.

Generally, petunias need to be deadheaded to keep them looking their best. There are some varieties touted as not needing much in the way of deadheading, but in my experience they do best with regular attention. Petunias will sometimes fade in the heat of midsummer; if you cut them back and fertilize them, you should get another flush of growth and more flowers.

Pansies are quite hardy and can take a light frost. Petunias are considered 'half hardy' but it's best to wait until after your last frost date to plant them outdoors.
