A. To get the maximum number of blooms from your snapdragons, Antirrhinum majus, pinch back the small plants when you first plant them in spring. This promotes lateral branches and discourages leggy, floppy growth common to the taller varieties. Staking the tall plants early in the season also is recommended.

Where do you pinch snapdragons?

After the transplants are established and growing, it's important to “pinch back” the plants. To pinch, simply use a clippers to remove the top of the plant, only leaving 2-3 sets of leaves behind. Pinching signals the plant to go into overdrive and send out multiple branches, with multiple blooms.

Do snapdragons need pinching out?

Once your antirrhinum seedlings have grown 6 leaves and are around 10 cm tall, pinch off the top of the stem to encourage bushiness and branching out. When you are ready to plant them outdoors, remember that snapdragons will grow most successfully in partial shade, as they prefer cooler temperatures.
