About Zantedeschia 'Mango'

Zantedeschia 'Mango' · also called Mango calla lily, orange calla · flowering

Zantedeschia 'Mango' is a warm-toned hybrid calla lily with sunset orange spathes blended with yellow and rose, held above dark green, often silver-spotted foliage. Grown from rhizomes, it flowers through summer in pots and borders. It wants bright indirect light, evenly moist free-draining soil in growth, and a dry winter rest, reaching about 40-60 cm.

Plant type: flowering

Watch for — Few flowers: Excess nitrogen or a pot-bound, exhausted rhizome reduces blooming; switch to a high-potassium feed and divide congested clumps.

The reasons zantedeschia 'mango' isn't blooming

Almost every non-blooming zantedeschia 'mango' 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 zantedeschia 'mango' 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 zantedeschia 'mango' to flower

Maximise sun. Give zantedeschia 'mango' 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 zantedeschia 'mango' and get the feeding right with the zantedeschia 'mango' 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

Zantedeschia 'Mango' 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 zantedeschia 'mango' care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

Zantedeschia 'Mango' blooming — frequently asked questions

Why won't my zantedeschia 'mango' flower?

Zantedeschia 'Mango' 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 zantedeschia 'mango' bloom?

Give zantedeschia 'mango' 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.
