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.

Mature size: 50-70 cm tall, 30-45 cm spread

How to tell calendula 'indian prince' needs repotting

Repotting on a calendar is less reliable than reading the plant. For calendula 'indian prince', watch for these signs:

Roots circling the bottom of the module or pot, or poking out of the drainage holes.
The seedling dries out within a day and growth has visibly stalled.
Roots are white and matted in a tight spiral when you tip the plant out.
It has outgrown its current container for the stage of the season — pot calendula 'indian prince' on before it becomes hard root-bound.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot calendula 'indian prince'

Pot on seedlings as they grow; not a perennial repot. Calendula 'Indian Prince'is grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Vigorous, taller-than-average upright bushy annual that branches well and reflowers freely with deadheading; good as a cut flower..

What size pot to step calendula 'indian prince' up to

Pot calendula 'indian prince' on gradually — a seedling jumped straight into a huge pot sits in cold, wet, airless soil and stalls. Step up one or two sizes at a time as the roots fill each container, finishing in a large final pot or the ground. The aim is roots that never circle and never check.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot calendula 'indian prince'

Pot calendula 'indian prince' on through the active growing season, whenever roots fill the current container — there is no single date, just "before it becomes root-bound". Avoid potting on during a cold snap.

Step-by-step: repotting calendula 'indian prince'

Pot on before it is root-bound. Check calendula 'indian prince' regularly; move it up as soon as roots reach the edge of the cell or pot, not after they have circled.
Step up one or two sizes. Choose the next container up — not a giant one. Cold, wet, unused soil around a small root system stalls seedlings.
Knock it out gently. Support the stem, tip the pot, and ease the rootball out without breaking it. A little teasing of circled roots at the base is fine.
Pot into rich mix. Set it into fresh average, well-drained soil, ph 6.0-7.0 at the same depth (tomatoes are the exception — they can go deeper to root along the stem).
Water in and grow on. Water well, keep it in good light, and resume feeding once it is established and growing again.

Aftercare

Water calendula 'indian prince' in well and keep it in bright light; a freshly potted-on seedling can wilt for a day while roots settle, so do not overcompensate by drowning it. Do not fertilise for about 1 week — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for calendula 'indian prince'

Calendula 'Indian Prince' wants average, well-drained soil, ph 6.0-7.0. Tolerant of ordinary and even poor soils. Sharp drainage matters more than richness; very fertile soil pushes foliage at the expense of flowers. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting calendula 'indian prince' — frequently asked questions

How often should you repot calendula 'indian prince'?

Pot on seedlings as they grow; not a perennial repot for calendula 'indian prince'. Calendula 'Indian Prince' is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into average, well-drained soil, ph 6.0-7.0 so the roots never circle the cell, ending in a large final container. A root-bound transplant stalls and never fully recovers.

What size pot does calendula 'indian prince' need?

When is the best time of year to repot calendula 'indian prince'?

Can you put calendula 'indian prince' straight into a much bigger pot?

No. Even a fast-growing calendula 'indian prince' should only go up one pot size at a time. A vastly oversized pot holds a reservoir of wet soil the roots cannot reach, which stays cold and soggy and rots the roots — the opposite of what you wanted.

Should you fertilise calendula 'indian prince' after repotting?

Not immediately. Wait about 1 week after repotting calendula 'indian prince'. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
