Let’s Start with How to Deadhead Petunias in Pots
Really we are talking about how to deadhead petunias in pots but it’s really all the same. Deadheading is simply remove old or dead flowers on your petunia plant.
Now this sounds basic but there is a right and wrong way to do it.
The wrong way, which a lot of people don’t realize, is to simply pull the flower out. It’s quick, it’s easy so it seems right but it’s not. When you just pull the petals out you’re missing the seed which is the primary part that needs to be removed.
When you go to pinch your flower, go lower to the base of the flower and pinch it off.
