About Calibrachoa 'Cabaret Deep Blue'

Calibrachoa × hybrida 'Cabaret Deep Blue' · also called Cabaret Deep Blue Calibrachoa, Deep Blue Million Bells · flowering

A floriferous calibrachoa from the Cabaret series with rich violet-blue, petunia-like bells smothering a mounded, semi-trailing plant. Bred for heat tolerance and non-stop bloom, it thrives in full sun in baskets and patio containers. A hungry, drainage-loving annual, it needs slightly acidic compost and weekly feeding to sustain the saturated blue colour all summer.

Mature size: 20-30 cm tall with a 25-40 cm spread; trails extend further in a large hanging basket.

Watch for — Aphids and spider mites: These sap-suckers attack soft new growth, especially in hot, dry spells. Hose off and apply insecticidal soap; raise humidity to discourage mites.

Indoor size vs how big it gets in the wild

Calibrachoa 'Cabaret Deep Blue' reaches its full size within one growing season — there is no "long-term" size, just how big it gets before you harvest or it dies back. Indoors and in a pot, expect 20-30 cm tall with a 25-40 cm spread. In the ground with no restriction it is a completely different plant — trails extend further in a large hanging basket. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It sizes up fast and once, racing from seedling to full size in a single season; after cropping it is finished, so size is a within-season question.

Growth rate and years to mature

Calibrachoa 'Cabaret Deep Blue' is a moderate grower. Realistically, expect a single growing season — it reaches full size in one year, then is done. Its feeding profile backs this up: feed weekly through the season with a balanced or slightly acidic liquid fertiliser, or use a controlled-release feed at planting. heavy feeding maintains the deep blue colour; pale, green-veined leaves indicate iron deficiency, treated with chelated iron or an ericaceous feed.

Want this turned into the right next pot at the right moment? The pot size calculator and the calibrachoa 'cabaret deep blue' repotting guide cover when and how much to size up — pot size is one of the biggest levers on how fast calibrachoa 'cabaret deep blue' grows.

How to keep calibrachoa 'cabaret deep blue' smaller

You are not stuck with the maximum size. For calibrachoa 'cabaret deep blue' specifically, these are the levers, in order of impact:

Choose a compact or dwarf variety of calibrachoa 'cabaret deep blue' from the start — that is the most reliable size control for an annual.
Grow it in a smaller container to naturally limit how large it gets.
For some crops, pinching or pruning the growing tips keeps the plant shorter and bushier.
Sow a little later or space plants closer if you specifically want smaller individual plants.

How to grow calibrachoa 'cabaret deep blue' bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for calibrachoa 'cabaret deep blue' the accelerators are:

Full sun, warm soil and steady water are what drive a crop to full size fastest.
Sow at the right time for your zone so it gets the whole season to size up.
Feed appropriately for the crop and never let it check (stall) from drought or cold.

Light is almost always the ceiling. The calibrachoa 'cabaret deep blue' light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When calibrachoa 'cabaret deep blue' outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for calibrachoa 'cabaret deep blue':

It sprawls beyond its bed or container before harvest — usually a spacing or support issue.
It flops or needs staking once it hits full height.
Once it has fruited or bolted, it is at its final size for good — the next plant is a new sowing.

If it is the pot rather than the room, it is a repotting job, not a goodbye — see the calibrachoa 'cabaret deep blue' repotting guide. If you want more of this plant instead of a bigger one, the calibrachoa 'cabaret deep blue' propagation guide turns prunings into new plants.
