About Catharanthus roseus 'Cora Cascade Strawberry'

Catharanthus roseus 'Cora Cascade Strawberry' · also called Cora Cascade Strawberry Vinca, Trailing Strawberry Vinca · flowering

'Cora Cascade Strawberry' is a trailing annual vinca bred for disease resistance, spilling strawberry-rose blooms with a deeper eye from hanging baskets and containers all summer. Loving heat and full sun, it is highly drought-tolerant once established and flowers tirelessly without deadheading. Note: all parts contain vinca alkaloids and are toxic to pets if eaten.

Growth habit: Spreading and cascading, with trailing stems that tumble over basket and container edges. Densely branched and self-cleaning, flowering continuously without deadheading.

What fertiliser catharanthus roseus 'cora cascade strawberry' actually wants — and why

Catharanthus roseus 'Cora Cascade Strawberry' is a heavy-blooming flower with a big appetite — a regular high-potash feed through the season is what drives a long, dense display.

A high-potassium ("high-potash") flowering feed — tomato-style or a dedicated bloom/rose feed. Potassium powers flowering; a high-nitrogen feed gives you a leafy plant with disappointing bloom.

For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for catharanthus roseus 'cora cascade strawberry': match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.

How often to feed catharanthus roseus 'cora cascade strawberry', and which months

Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For catharanthus roseus 'cora cascade strawberry':

Feed lightly every 3-4 weeks with a balanced liquid fertiliser, or use slow-release granules at planting. Vinca needs little feeding and over-fertilising encourages soft growth and fewer flowers. For a hungry bloomer that means feeding regularly — every 3-4 weeks — right through flowering across the main season (spring through early autumn), tapering as blooming ends.

The dormant-season rule matters more than the exact interval: skip feeding entirely when catharanthus roseus 'cora cascade strawberry' is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.

What strength to mix for catharanthus roseus 'cora cascade strawberry'

Follow the flowering-feed label rate for catharanthus roseus 'cora cascade strawberry', or half strength if feeding very frequently. These plants genuinely use the nutrients — under-feeding shows up fast as a thin display.

Feeding always goes onto already-damp soil, never dry roots — water catharanthus roseus 'cora cascade strawberry' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the catharanthus roseus 'cora cascade strawberry' watering schedule.

Signs you are over-feeding catharanthus roseus 'cora cascade strawberry'

Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for catharanthus roseus 'cora cascade strawberry':

Lots of lush leaves but few flowers (too much nitrogen).
Scorched leaf edges and salt crust from too-strong or too-frequent feeds.
Soft, sappy growth prone to aphids and mildew.

Signs you are under-feeding catharanthus roseus 'cora cascade strawberry'

Sparse, small, short-lived flowers and pale foliage.
A tired plant that stops blooming early in the season.
Weak growth and poor repeat-flowering after the first flush.

If the symptoms point at watering, light or roots rather than nutrition, the full catharanthus roseus 'cora cascade strawberry' care brief covers soil, humidity and the common problems for this species.

Flushing and leaching the salts

Container-grown catharanthus roseus 'cora cascade strawberry' accumulates feed salts fast with frequent feeding — water until it drains each time and flush pots with plain water every few weeks to prevent scorch.

Organic vs synthetic feeds for catharanthus roseus 'cora cascade strawberry'

Organic options

A liquid comfrey or seaweed feed (naturally potassium-rich) plus compost or well-rotted manure as a mulch. UK: comfrey feed, organic Tomorite, or rose feed; US: Espoma Rose-tone or Neptune's Harvest. Feeds and improves soil.

Synthetic / liquid feeds

A high-potash flowering feed on a regular cadence — UK: Tomorite (Levington), Phostrogen or a specialist rose feed; US: Miracle-Gro Bloom Booster or a rose food. Fast, reliable bloom response.

Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.
