Mastering the Art of Pricking Out and Transplanting Snapdragons

       Snapdragons are a classic flower to grow for Springtime blooms and I can’t imagine my cut flower garden without them! Snapdragons are popular in both garden beds and floral arrangements due to their long-lasting blooms and ability to add vertical interest. They also attract pollinators, such as bees,  making them a favorite among gardeners. Snapdragons come in a variety of colors and height. Some snapdragons are great for boarders and containers due to their shorter nature while others get over 2 feet making them great for cut flower bouquets. I love Snapdragons but I have just one problem with them- the seeds are so tiny that I can hardly see to sow them! After having a hard time sowing them one by one, one day I sowed a whole packed in a shallow container to see if it made things any easier. Boy, did it!  I discovered the "pricking out" method and this is how I sow snapdragon seeds now!

What is Pricking Out?

Pricking out is the careful process of transplanting tiny seedlings from a densely sown tray into individual cells or pots. Since snapdragons start off so small, they often germinate close together, and if they’re not given more space, they can become weak and leggy. By moving them into their own space after a few weeks of growth, you’re setting them up for success!

Why Snapdragons Need Special Care at This Stage

Snapdragons have fine, delicate roots, which makes this step a little more tricky than with other seedlings. If handled too roughly or left too crowded for too long, they may struggle to establish strong growth. But with the right technique, they’ll barely notice the transition—and that’s exactly what I show you in my latest YouTube video!

A Few Quick Tips Before You Start:
  • Be patient—tiny seedlings require a gentle touch!
  • Always hold seedlings by their leaves, not the stem.
  • I've pricked out Snapdragons as early as just having their cotyledon leaves up until their first set of true leaves. I prick out Snapdragons when they are in this young stage to minimize root disturbance. The bigger the Snapdragon, the bigger the roots!
  • The more moist the soil is while pricking out, the easier it is to slide the seedling and roots out with minimal disturbance. Drier soil causes roots to break easier. 
  • Keep the soil evenly moist after transplanting to help them adjust.

In this YouTube video, I share a step-by-step guide on pricking out and transplanting snapdragon seedlings. I show you how to carefully handle the delicate seedlings, space them properly, and set them up for strong, healthy growth. Whether you’re new to growing snapdragons or looking for tips to refine your technique, this tutorial is perfect for growers of all levels.

Snapdragons are a must-grow for any cut flower garden! With their tall, elegant spikes, long vase life, and stunning range of colors, they add beauty and structure to bouquets from spring through fall. These cool-weather lovers are mid-Spring bloomers and can keep producing with regular harvesting until the heat of the summer. Plus, they’re cut-and-come-again, meaning the more you cut, the more they bloom! Whether you’re growing for market bouquets or just to brighten your home, snapdragons are an easy, rewarding choice.

Snapdragons are one of the 20 flowers talked about in my Cut Flower Seed Starting Schedule E-book. More info can be found in the Flower Shop!
