Dead snapdragons – Don’t ruin your plant

Snapdragons are one of my personal favorites. I love how they look in the garden, and I always get a kick out of looking at the dead flower heads that resemble that of a human skull. What’s even more bizarre is if you squeeze them between your fingertips – the skull will open and close its mouth! But even I have to admit, they can be a bit temperamental, and deadheading them often leaves many gardeners confused. Let’s explore dead snapdragons below:

Snapdragons Overview

The scientific name for snapdragons is Antirrhinum, but they are also known as dragon flowers or dog flowers. Snapdragons usually grow in the wild in North America, Canada, North Africa, and Europe.

Many people all around the world love snapdragons for their cheerful disposition and wide array of colors. Snapdragons are usually short-lived perennials that grow as annuals, which means they’re ideal for flower gardeners who want to switch up their color palette every year. You will often see them in classic British-style gardens because they have many uses: They can be used in mixed border gardens, planted in large flower boxes, or different types of patio containers.

It is thought that the name snapdragon comes from the appearance of the individual flower heads which resemble that of a dragon snout (I think they look more like a human skull). What solidifies this thought further is that the flower head can open and close its mouth when pinched by someone’s fingertips.

What makes snapdragons so incredible is that they bloom profusely throughout the cool weather and all different shades of colors. You will see them look their best in either the spring or fall in the garden. Usually, snapdragons will start to slow down their blooming period during the summer as the temperature starts to rise however if you keep them watered, they will perk up and carry your garden through to the fall.

Do you deadhead snapdragons?

Yes, you should deadhead snapdragons to prolong their blooming period. Discard any wilted or dying flowers and cut the stem beneath the blossom using scissors. Remove deadheads from snapdragon plants and keep an eye on the leaves for any new growth.

Deadheading in general allows the plant to focus its energy on producing new flowers rather than seed production. This is beneficial to the plant because it will continue to bloom for a longer period of time. Additionally, deadheading helps to keep the snapdragon plant tidy and looking its best.

If you want to deadhead your snapdragon, make sure you do so after the plant has bloomed. Cutting off the dead blooms will help encourage the plant to produce new flowers.

What to do with snapdragons after flowering?

If you want to keep your snapdragon plant around after it has finished blooming, you can cut it back by about one-third. This will help encourage new growth and give the plant a chance to rest. Additionally, make sure to fertilize your snapdragon plant after it has been cut back to help promote new growth.

You can also deadhead your snapdragons and discard the blooms and put them in your compost bin. Composting is a great idea because it lowers the risk of pests and diseases getting into your garden.

It is generally recommended that you discard snapdragon plants after they have bloomed and start fresh the following year. This is because snapdragons are typically short-lived perennials that grow as annuals. However, if you take good care of your snapdragon plant, it may come back the following year.
