More about blanket flower

About Blanket flower

Gaillardia x grandiflora · also called Blanket flower, Great blanket flower · flowering

A sun-loving, drought-tolerant perennial producing vivid daisy-like flowers in bold combinations of red, orange, and yellow from early summer right through to the first frosts. Outstanding prairie and xeriscape plant. Pet-safe per ASPCA. Requires excellent drainage to persist; tends to be short-lived in heavy, wet soils but reseeds readily.

Plant type: flowering

Watch for — Crown rot and short lifespan: The most significant issue. Blanket flowers are naturally short-lived (often two to three years) and this is greatly accelerated by wet or clay soils. Excellent drainage, lean soil, and avoiding overwatering are the keys to longevity. Lift and divide annually if needed.

The reasons blanket flower isn't blooming

Almost every non-blooming blanket flower 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 blanket flower 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 blanket flower to flower

  1. Maximise sun. Give blanket flower 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 blanket flower and get the feeding right with the blanket flower 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

Blanket flower 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 blanket flower care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

Blanket flower blooming — frequently asked questions

Why won't my blanket flower flower?

Blanket flower 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 blanket flower bloom?

Give blanket flower 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 blanket flower normally bloom?

Blanket flower 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 blanket flower 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 blanket flower flowering?

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