Dahlia 'Mingus Tina' (Mingus Tina dahlia) care

Light

Dahlia 'Mingus Tina' needs sun on the leaves, not just bright ambient room light. Requires at least 6-8 hours of direct sun daily. Full sun maximises bloom size, stem strength, and flower count. Avoid shaded positions, which lead to weak stems and reduced flowering. A south or west-facing windowsill in the northern hemisphere is the default; anywhere else, expect the plant to stretch and pale out within a season.

Watering

Water dahlia 'mingus tina' every 3-4 days during active growth, more frequently in hot weather. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. Water deeply at the base, keeping foliage dry to reduce disease risk. Allow the top 2-3 cm of soil to dry between waterings. Reduce watering as foliage yellows in autumn and stop entirely once tubers are lifted for winter storage.

Soil and pot

Dahlia 'Mingus Tina' grows best in rich, free-draining loam. Incorporate plenty of well-rotted organic matter before planting. A slightly acidic to neutral pH of 6.0-7.0 is ideal. Avoid waterlogged ground, which causes tuber rot. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Dahlia 'Mingus Tina' sits happiest at around 40-60% humidity and 10-30°C (50-86°F). Dahlias prefer moderate ambient humidity. High humidity combined with poor air circulation encourages powdery mildew. Space plants 60-90 cm apart to allow airflow. If you keep the room above 10 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed dahlia 'mingus tina' sparingly. Feed with a low-nitrogen, high-potassium liquid fertiliser every 2 weeks from bud formation through late summer. Avoid high-nitrogen feeds, which promote leafy growth at the expense of blooms. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on dahlia 'mingus tina' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Powdery mildew — White powdery coating on leaves in humid, crowded conditions. Improve air circulation and apply a dilute sulphur-based spray if severe.
• Earwig damage — Ragged holes in petals overnight. Trap earwigs in damp rolled newspaper placed near plants and dispose of in the morning.
• Slug and snail damage — Young shoots and tubers are vulnerable. Use organic iron phosphate pellets and remove debris where pests shelter.
• Tuber rot — Caused by waterlogged soil or poorly stored tubers. Ensure free drainage; dust cut surfaces with sulphur before storing tubers over winter.
• Aphids — Clusters on new growth stunt shoots and transmit viruses. Blast off with water or apply insecticidal soap.

Companion plants

Dahlia 'Mingus Tina' pairs well with Rudbeckia hirta, Echinacea purpurea, Zinnia elegans, and Cosmos bipinnatus. These are species with similar light and water needs, so you can group them in the same room or on the same shelf and water as a batch.

Propagation

Divide tubers in spring, ensuring each division has at least one visible eye (growing point) and some attached tuber. Cuttings can also be taken from young basal shoots in spring and rooted in a free-draining propagating mix. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Dahlia 'Mingus Tina' is toxic to pets. The ASPCA lists Dahlia as toxic to dogs and cats. Ingestion can cause mild gastrointestinal upset and skin irritation. Keep pets away from tubers and flowers. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
