What does pinching petunias mean?
Pinching petunias means you pinch or snip back a bit of the petunia plant to encourage branching. It is roughly the same thing as pruning petunias, but often pinching is done on young plants before they reach their full size potential.
Should you prune petunias?
Yes, it is usually a good idea to prune petunias for fuller plants with more blooms. Pruning helps to transform a spindly petunia plant to a lush and more compact plant.
Pruning wave petunias is not necessary, but most traditional petunias thrive when pruned regularly.
When do you cut back petunias?
You can pinch petunias as soon as you plant them in your garden. Even for hanging baskets and planters, prune a few stems as soon as you come home from the store. Encourage all those new flowers!
How often should you be pruning petunias?
When possible, aim to prune petunias at least once per week on a rolling basis. This helps to ensure that some parts of the plant are always in bloom or nearing blooms.
Pruning petunias monthly can work if you haven’t got the time every week. In this case, cut the petunias back by the middle of summer so they still have time to bush out for the rest of the season.
How far do you cut back petunias?
You can cut petunias back by anywhere from 1/5 to 1/2 their height / length. Consider if the petunia is leggy and trim accordingly.
