Planting and sowing snapdragon

Snapdragon is a plant that self-sows year after year, and this will explain how to get the cycle launched at the start.

How to plant snapdragon

If you intend to directly purchase your snapdragon in nursery pots, it is best to plant it in spring, towards the month of May, for it to bloom in summer.

Whether the plant is in a container or in the ground, select a sun-filled spot for maximum blooming.

  • Snapdragon likes well-drained ground.
  • Always maintain sufficient moisture in the soil, from the planting all the way up to the blooming.

In pots, simply make sure drainage is very good (holes at the bottom of the pot) for excess water to drain away. Here, pink snapdragon is paired with potted lavender.

Sowing snapdragon

If you’re looking to sow snapdragon seeds, get started at the end of winter and transplant in spring.

  • Sow under cover or in a nursery in March or April.
  • Transplant to the ground in May, ideally when the last frosts are past.

Caring for snapdragon

Snapdragon is a plant that only calls for very little attention.

  • To enhance flower-bearing, remove wilted flowers regularly.
  • During spells of high temperatures, feel free to water in the evening to avoid having your snapdragon dry out.
  • Adding liquid fertilizer during the blooming will generate more numerous flowers and make their colors more dazzling.

Simply leaving your snapdragons be without disturbing them will ensure they re-sow spontaneously year after year.

Snapdragon in winter

Even though it is an annual plant, snapdragon can perfectly withstand mild winters and sow seeds again and again.

It can hold to temperatures down to about 23°F (-5°C).

If you live in an area where the winter is very cold, try to protect your snapdragon with a thick cover of dried leaves, hoping to see the seeds sprout in the following spring.
