I've had this baby pink snapdragon for about 3 to 4 years and I've noticed that this growing season its growth is very slow and stunted. For example, last year the plant grew to 3 ft tall and now it's approximately 1 ft tall. I'm thinking I might have to divide the plant with a shovel or do something else. During the winter, I overwinter the plant by placing leaf mulch around it. I usually don't prune it until the upcoming spring. Should I prune it before the first frost and then mulch? How much should I prune it? Thanks for your help and suggestions.
These plants normally cannot be divided successfully and are normally propagated via seed or cuttings. Snapdragons are most often treated as annuals, though they are actually tender, short-lived perennials. It could be that your plant is reaching the end of its days, so you may want to save some seeds or take some cuttings from it to start again, just in case. As for pruning, once the blooms have faded, you can cut the plant back by one half to one third (save some cuttings).
Should I pull my short plants this fall or if I leave them in the ground for the winter, might they grow in the spring?
You can pull them, leave them, or harvest seeds. Most snapdragons are self-seeding annuals, so they will come back each year, but they are not necessarily going to be the same plants as the year before. There are a few varieties that are considered perennial, in Zones 9-10; however, most are not. Many of the seeds remain cold hardy to -30 so they will normally remain viable throughout winter and new plants will pop up in the spring.
Do I cut out the dead flower stalks?
Dead heading the spent blossoms will help encourage more flowering.
Here is a link that will help with growing information.
I was checking out a very rambunctious snapdragon and a whole stalk that is about to flower came off from the base of the plant! Can I replant it?!
No, I'm sorry, this will not regrow.
If you have a flower on the other end of this stem, cut it and place in fresh water to enjoy as a fresh cut flower.
I'm fascinated by the tiny skull like seed pods Snapdragons produce. Do all varieties produce the pods, and will they only occur if the flower is pollinated? I live in a city with no outdoor growing area, and am wanting to grow a dwarf variety in a terrarium. Will I get any pods without bees getting to the flowers?
If you Snapdragons flower they will form seeds, some hybrids however will produce few or sterile seeds.
We live in Boston and had a relatively mild winter. We cut our rather extensive snapdragon plants back almost to the ground last fall, but they all came back up and, in fact, spread. Quite a nice show of pink and yellow but knowing that they are actually annuals in zone 6, we are wondering what to do with them at the end of the season? So you think that they will come up once again in the spring or should we remove them and plant more?
If the winter is mild enough climate Snapdragon can be a short lived perennial.
Certainly enjoy the plants as long as you can grow them and would like to!
Do I need to pick the snapdragon pods before the fall freeze or will they still grow plants if they have been in temps. below 32?
Every year my snapdragons come back from the fallen pods that are left over winter. I usually just snap them off and leave them.
