Getting it to bloom

Why won't my Pansy bloom? (and how to make it flower)

Also called garden pansy, heartsease (small viola), winter pansy (Viola × wittrockiana).

About Pansy

Viola × wittrockiana · also called garden pansy, heartsease (small viola) · flowering

Pansies are cool-season annuals or short-lived perennials with cheerful face-like flowers. Plant autumn for winter and spring colour in mild zones, or spring through early summer in cooler areas. Pet-safe and edible.

Viola x wittrockiana is a hybrid cool-season bedding plant grown as an annual or short-lived perennial, valued for face-like blooms over a long cool-weather season in spring and fall.

Plant type: flowering

Watch for — Stops blooming in heat: Above 21°C they stop; remove and replant in autumn.

The reasons pansy isn't blooming

Almost every non-blooming pansy traces back to one of these, roughly in order of how common they are:

  1. Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
  2. Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
  3. The plant has not been deadheaded, so it stops flowering once it sets seed.
  4. Irregular watering — drought or waterlogging at the budding stage makes buds abort.
  5. It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding pansy a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.

The fix — how to get pansy to flower

  1. Maximise sun. Give pansy the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
  2. Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
  3. Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
  4. Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.

Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for pansy and get the feeding right with the pansy fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.

Bloom season and what to expect

Pansy flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

Post-bloom care so it flowers again

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.

For everything else this plant needs day to day, see the full pansy care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

Pansy blooming — frequently asked questions

Why won't my pansy flower?

Pansy blooms on the season's growth given enough sun, warmth and the right feed — there is no cold or photoperiod trick, just good growing conditions and a bloom-leaning feed. The most common reason it is not happening: Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.

How do I make pansy bloom?

Give pansy the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.

When does pansy normally bloom?

Pansy flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

What should I do with pansy after it flowers?

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.

What is the single biggest mistake stopping pansy flowering?

Feeding pansy a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.
