About Bougainvillea 'Raspberry Ice'

Bougainvillea 'Raspberry Ice' · also called Variegated Bougainvillea · flowering

Bougainvillea 'Raspberry Ice' is a compact, mounding cultivar grown as much for its cream-edged variegated foliage as for its rich raspberry-pink bracts. Lower and more cascading than climbing types, it suits hanging baskets, low walls, and containers. Like all bougainvilleas it craves full sun, lean fast-draining soil, and slightly dry roots to flower well, and is frost-tender.

Plant type: flowering

Watch for — Few bracts: Overwatering or high-nitrogen feed; let it dry between waterings and use a bloom-boosting low-nitrogen fertiliser.

The reasons bougainvillea 'raspberry ice' isn't blooming

Almost every non-blooming bougainvillea 'raspberry ice' 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 bougainvillea 'raspberry ice' 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 bougainvillea 'raspberry ice' to flower

Maximise sun. Give bougainvillea 'raspberry ice' 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 bougainvillea 'raspberry ice' and get the feeding right with the bougainvillea 'raspberry ice' 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

Bougainvillea 'Raspberry Ice' 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 bougainvillea 'raspberry ice' care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

Bougainvillea 'Raspberry Ice' blooming — frequently asked questions

Why won't my bougainvillea 'raspberry ice' flower?

Bougainvillea 'Raspberry Ice' 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 bougainvillea 'raspberry ice' bloom?

Give bougainvillea 'raspberry ice' 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.
