About Pompon Dahlia 'Jowey Mirella'

Dahlia 'Jowey Mirella' · also called Ball dahlia · flowering

'Jowey Mirella' is a ball dahlia bearing tightly quilled, fully double burgundy-red blooms on long, strong stems, prized as a cut flower. Tubers are lifted or mulched over winter in colder zones. Plant in full sun in rich, free-draining soil after frost, stake early, and deadhead to keep flowering until autumn.

Plant type: flowering

Watch for — Flopping stems: Tall, top-heavy flowering stems snap in wind or rain. Stake at planting and tie in as the plant grows.

The reasons pompon dahlia 'jowey mirella' isn't blooming

Almost every non-blooming pompon dahlia 'jowey mirella' 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 pompon dahlia 'jowey mirella' 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 pompon dahlia 'jowey mirella' to flower

Maximise sun. Give pompon dahlia 'jowey mirella' 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 pompon dahlia 'jowey mirella' and get the feeding right with the pompon dahlia 'jowey mirella' 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

Pompon Dahlia 'Jowey Mirella' 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.
