About Calendula 'Indian Prince'

Calendula officinalis 'Indian Prince' · also called Indian Prince marigold, dark-centre calendula · flowering

Calendula 'Indian Prince' is a tall, robust pot marigold prized for deep burnt-orange flowers with mahogany-red reverses and a dark centre. An easy hardy annual, it flowers prolifically from seed in full sun, resists mildew better than many strains, and the edible petals suit cutting and cottage borders. Deadheading sustains a long, pollinator-friendly display.

Plant type: flowering

Watch for — Aphids: Gather on buds and shoot tips. Rinse off with water or treat with insecticidal soap; the plant also lures beneficial predators.

The reasons calendula 'indian prince' isn't blooming

Almost every non-blooming calendula 'indian prince' 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 calendula 'indian prince' 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 calendula 'indian prince' to flower

Maximise sun. Give calendula 'indian prince' 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 calendula 'indian prince' and get the feeding right with the calendula 'indian prince' 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

Calendula 'Indian Prince' 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.
