Dahlia Alauna chamade

Growing in Pots, Balconies & Indoors

Dahlias are showy, tuberous summer-flowering plants (about 0.3-1.5 m tall, sometimes more) – not houseplants, but first-rate container plants for a sunny balcony or patio. Indoors the light is far too weak for them to bloom, so grow them outdoors in strong sun and, in cold climates, overwinter the dormant tubers under cover.

Quick Details

• Container Size: A large, deep pot (roughly 10-30 L / 2.5-8 gal) to support the tubers and top growth
• Indoor Suitability: Not an indoor houseplant – it needs strong outdoor light to flower
• Best Spot: Full sun, outdoors
• Soil & Drainage: Free-draining, organic-rich mix – potting mix or peat with perlite or vermiculite
• Watering in Pots: Average water; keep evenly moist but never waterlogged – tubers rot in standing water

Indoors & On the Windowsill

• Houseplant limits: The grower confirms dahlias are not indoor houseplants – they need strong outdoor light to bloom.
• Overwintering indoors: This is the main reason to bring them under cover. After the top dies back, lift the tubers (or move the whole pot) and store them cool, dry and frost-free while dormant, then restart them in the warm season.

On a Balcony or Patio

• Light & wind: Give the sunniest spot. Taller varieties grow top-heavy in bloom, so stake them and shelter from strong wind. Walls and paving reflect heat and pots dry fast – check moisture often.

Choosing the Pot, Soil & Long-Term Care

• Pot & drainage: A large, deep pot with strong drainage holes; skip a standing-water saucer to protect the tubers from rot.
• Potting mix: Free-draining and organic-rich – potting mix or peat with perlite or vermiculite.
• Feeding: Container dahlias need regular feeding as nutrients leach; a bloom-type (lower-nitrogen) feed supports flowering.
• Tubers & repotting: Each dormant season lift and divide the tubers, then restart them in fresh mix in a large pot.

Bloom & Edible Flower Guide

Quick Details

• Bloom Season: From late spring through summer to the first frost of autumn
• Time to First Bloom: Roughly 8 to 12 weeks after the tubers are planted
• Flower Appearance: Colours arranged in rings — a yellow centre with orange and pink toward the outside; broad, pointed petals
• Edibility: The petals are edible (dahlias are a recognised edible flower) — use only blooms grown without pesticides

Detailed Blooming Overview

‘Alauna chamade’ is a decorative dahlia, with a full, rounded bloom of broad petals whose colours are arranged in rings — yellow in the middle grading to orange and pink at the edge. Like all dahlias it flowers generously from late spring right up to the first autumn frost, and the long, straight stems make it an excellent cut flower.

Flower Characteristics

• Colours organised in circles: a yellow centre, with orange and pink in the outer ring; petals ovate to elliptic with pointed tips and a wide base.
• Decorative form: broad, flat petals with pointed tips, packed into a full bloom.

Bloom Care & Thinning

• Deadheading: Remove spent blooms regularly to keep fresh flowers coming right up to the first frost.
• Disbudding: For fewer but larger, show-quality blooms, pinch out the small side buds beside each main bud.
• Pinching: Pinching out the growing tip while the plant is young encourages a bushier plant with more flowering stems.
• Support: Taller plants flower better when staked, as the stems can be brittle and heavy in bloom.

Bloom Health & Protection

• Earwigs chew ragged holes in petals and buds overnight; loosely stuffed pots or rolled cardboard traps set among the plants help catch them.
• Aphids and thrips cluster on buds and can distort or streak the blooms; insecticidal soap or neem oil keeps them in check.
• Grey mould (Botrytis) can rot open flowers in damp weather and powdery mildew can film the foliage; removing affected blooms, improving airflow and a sulfur-based fungicide all help.
