About Gaillardia 'Arizona Sun'
Gaillardia x grandiflora 'Arizona Sun' · also called Arizona Sun blanket flower · flowering
Gaillardia 'Arizona Sun' is an award-winning compact blanket flower bearing large mahogany-red daisies edged in bright yellow from early summer until frost. Bred for uniform, fast flowering from seed, it loves full sun and dry, well-drained soil, tolerates heat and drought, and is a magnet for bees and butterflies.
Plant type: flowering
Watch for — Aster yellows: Phytoplasma disease spread by leafhoppers, distorting and greening the flowers. Pull and destroy infected plants promptly.
The reasons gaillardia 'arizona sun' isn't blooming
Almost every non-blooming gaillardia 'arizona sun' traces back to one of these, roughly in order of how common they are:
- Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
- Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
- The plant has not been deadheaded, so it stops flowering once it sets seed.
- Irregular watering — drought or waterlogging at the budding stage makes buds abort.
- It is still too young or was checked by a transplant and is rebuilding before flowering.
Feeding gaillardia 'arizona sun' 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 gaillardia 'arizona sun' to flower
- Maximise sun. Give gaillardia 'arizona sun' the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
- Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
- Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
- 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 gaillardia 'arizona sun' and get the feeding right with the gaillardia 'arizona sun' fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.
