About French Marigold 'Durango'

Tagetes patula 'Durango' · also called French marigold · flowering

'Durango' is a compact, well-branched French marigold series bearing large, fully double anemone-form flowers in golden, orange, red, bicolour and bee tones. A heat-tolerant warm-season annual, it blooms early and continuously from spring to frost in full sun, ideal for bedding and containers. Aromatic foliage deters some pests; mildly toxic to pets via thiophenes.

Mature size: 20-30 cm tall and 20-30 cm wide; flowers 5-6 cm across.

Watch for — Few flowers, leafy growth: Over-rich soil or too much nitrogen and shade give lush leaves but sparse bloom. Site in full sun and use a balanced or potassium-leaning feed rather than high-nitrogen fertiliser.

How to tell french marigold 'durango' needs repotting

Repotting on a calendar is less reliable than reading the plant. For french marigold 'durango', 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 french marigold 'durango' 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 french marigold 'durango'

Pot on seedlings as they grow; not a perennial repot. French Marigold 'Durango'is grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Compact, uniform, densely branching annual mound covered in large double flowers; one of the earliest and most floriferous French marigold series..

What size pot to step french marigold 'durango' up to

Pot french marigold 'durango' 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 french marigold 'durango'

Pot french marigold 'durango' 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 french marigold 'durango'

Pot on before it is root-bound. Check french marigold 'durango' 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 moderately fertile, well-drained soil 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 french marigold 'durango' 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 french marigold 'durango'

French Marigold 'Durango' wants moderately fertile, well-drained soil. Adaptable to most garden soils with good drainage; slightly acidic to neutral pH is ideal. Avoid overly rich soil, which favours foliage over flowers, and heavy wet ground that rots roots. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting french marigold 'durango' — frequently asked questions

How often should you repot french marigold 'durango'?

Pot on seedlings as they grow; not a perennial repot for french marigold 'durango'. French Marigold 'Durango' is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into moderately fertile, well-drained soil 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 french marigold 'durango' need?

When is the best time of year to repot french marigold 'durango'?

Can you put french marigold 'durango' straight into a much bigger pot?

No. Even a fast-growing french marigold 'durango' 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 french marigold 'durango' after repotting?

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