Does Antirrhinum Grow Back Every Year?

Snapdragons (antirrhinum) tends to be a short-lived plant, so it should be replanted every year.

What’s the Best Time to Plant Antirrhinum Flower?

In autumn or early spring, sow the antirrhinum seeds in a greenhouse or on a covered tray on a sunny windowsill. Place seeds on a layer of compost. Water them, then seal the bag with a propagator. When the seeds are large enough to be handled, transfer them into pots. Then, grow in a cold frame or sheltered place. After the danger of frost is gone, plant them out. Planting in autumn will bring you early May flowers.

Propagating Snapdragons

Caring for Snapdragon Flower

You can prolong the flowering season by feeding your plants weekly with a fertilizer rich in potash. It’s best to deadhead any spent blooms. If necessary, water plants regularly and cane taller varieties if you need to.
