About Zinnia elegans 'Profusion Cherry'

Zinnia elegans 'Profusion Cherry' · also called Profusion Cherry Zinnia, Mildew-resistant Cherry Zinnia · flowering

'Profusion Cherry' is an award-winning interspecific zinnia (Z. elegans × Z. angustifolia) bearing single cherry-rose daisy blooms on compact, self-branching mounds. An All-America Selections winner, it offers exceptional resistance to powdery mildew, leaf spot and weather. Low-maintenance, heat- and drought-tolerant and self-cleaning, it flowers nonstop from early summer to frost, perfect for beds and containers.

Mature size: 30-45 cm tall and 30-45 cm wide.

Watch for — Overwatering and root rot: Constantly wet or poorly drained soil rots the roots. Let soil dry between waterings and ensure containers drain freely.

How to tell zinnia elegans 'profusion cherry' needs repotting

Repotting on a calendar is less reliable than reading the plant. For zinnia elegans 'profusion cherry', 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 zinnia elegans 'profusion cherry' 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 zinnia elegans 'profusion cherry'

Pot on seedlings as they grow; not a perennial repot. Zinnia elegans 'Profusion Cherry'is grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Compact, dense, self-branching mounding annual that is self-cleaning, dropping spent blooms on its own and needing virtually no deadheading..

What size pot to step zinnia elegans 'profusion cherry' up to

Pot zinnia elegans 'profusion cherry' 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 zinnia elegans 'profusion cherry'

Pot zinnia elegans 'profusion cherry' 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 zinnia elegans 'profusion cherry'

Pot on before it is root-bound. Check zinnia elegans 'profusion cherry' 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 well-drained, average garden soil or quality container compost 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 zinnia elegans 'profusion cherry' 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 zinnia elegans 'profusion cherry'

Zinnia elegans 'Profusion Cherry' wants well-drained, average garden soil or quality container compost. Adaptable and undemanding; prefers free-draining soil at pH 5.5-7.5. It performs well even in lean soils, far more forgiving than tall florist zinnias. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting zinnia elegans 'profusion cherry' — frequently asked questions

How often should you repot zinnia elegans 'profusion cherry'?

Pot on seedlings as they grow; not a perennial repot for zinnia elegans 'profusion cherry'. Zinnia elegans 'Profusion Cherry' is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into well-drained, average garden soil or quality container compost 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 zinnia elegans 'profusion cherry' need?

When is the best time of year to repot zinnia elegans 'profusion cherry'?

Can you put zinnia elegans 'profusion cherry' straight into a much bigger pot?

No. Even a fast-growing zinnia elegans 'profusion cherry' 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 zinnia elegans 'profusion cherry' after repotting?

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