About Supertunia 'Vista Bubblegum'

Petunia 'Vista Bubblegum' · also called Supertunia · flowering

Supertunia 'Vista Bubblegum' is a mounding, vigorous pink petunia famed for blooming all season with no deadheading and shrugging off heat and rain. It grows large fast, filling beds and big containers. Like all Supertunias it is a hungry, thirsty feeder. ASPCA-listed as non-toxic to cats and dogs.

Plant type: flowering

Watch for — Nutrient deficiency / yellowing: Pale lower leaves and weak bloom signal hunger or iron chlorosis; this vigorous cultivar needs consistent feeding to look its best.

The reasons supertunia 'vista bubblegum' isn't blooming

Almost every non-blooming supertunia 'vista bubblegum' 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 supertunia 'vista bubblegum' 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 supertunia 'vista bubblegum' to flower

Maximise sun. Give supertunia 'vista bubblegum' 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 supertunia 'vista bubblegum' and get the feeding right with the supertunia 'vista bubblegum' 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

Supertunia 'Vista Bubblegum' 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.
