I'm in the midst of the most prolific harvest of snapdragons you've ever seen. Not only are they fragrant, but their beauty is the kind that almost hurts your heart. With a little bit of planning, they're pretty easy to grow! I'm here to tell you how.
Plan now for fall planting. I usually recommend placing orders for your desired flower seed as that particular flower's season comes to a close. I'll have these snaps for a few more weeks, then I'll go over my harvest records, decide which snaps I like the best (or if there was one I wouldn't order again) then place my seed order. Once the seeds arrive, I keep them stored in a cool, dark, dry place until I need them in the fall. I always like to order early so that I don't get caught in a pinch if the varieties I want are back-ordered.
I planted these snapdragons with my students back in October. They are a little finicky. (The snapdragons, not the students!) The seeds are TINY and must be kept on top of the soil, because they need light to germinate. I germinated them indoors, then planted them outside after they had several sets of true leaves.This took about six weeks. While I was waiting for them to grow, I made sure my beds were free of debris, and I applied Mighty Grow fertilizer. Once ready, I planted my snapdragons about a foot apart. I planted them this far apart, because I wanted lots of side branches on mine. If you want longer, stronger stems, you can plant them four inches apart. If you do it this way, you'll only get one cut from each plant.
If you want perfectly straight snapdragons that never tilt over, you'll want to add an extra step before you plant: installing Hortonova. I recommend pounding rebar into the corners of your beds and about every four to six feet along the length of your beds. Stretch your Hortonova tight over the top of the bed so that it is completely parallel to you soil below, about a foot above the ground. You can even use taller rebar and add a second layer of Hortonova another 8-12" above your first layer for extra support. I like to make sure the netting is extra secure by using small zip ties to attach it to the rebar. The Hortonova makes it a lot easier to perfectly space your plants, because it basically lays out a perfect grid on top of your soil. It's also great for all you perfectionists out there: I've gotten a few funky shaped snapdragons, because snaps are geotropic. That means that if the stems have fallen over and are at an angle to the ground, the blooms will bend themselves back up to try and grow straight up to the sky.
I pinched my seedlings back to about half their height when I transplanted them in early November. I made sure to keep them covered with frost cloth during times when the temperatures were dropping well below freezing. I pinched them a few times throughout the winter.
I planted three different kinds of snapdragons to try and extend my snapdragon season. My Rocket snapdragons bloomed first, followed by Potomacs, and then Madame Butterfly. Madame Butterfly snaps are frillier open-faced blooms that don't have the traditional snapdragon look. But I think they're stunning, so I grow them, too.
These flowers have just shattered my heart with their beauty and fragrance. I've gotten hundreds of stems over three feet tall, and lots of beautiful side stems that are a little smaller that have been wonderful for smaller arrangements. I harvest them when the the flower spikes are about 1/3 open. I strip all the leaves off before putting them in my harvest bucket. I've been posting pictures of the snapdragons' progress over on my social media accounts, so check them out.
If you like what you see, I highly recommend planning now to plant them this fall. You won't be disappointed!
