Germination Temperature: The optimal germination temperature for Dahlia seeds is 18-24°C, with many sources recommending 21-24°C for best results.

Germination Time: Dahlia seeds typically germinate in 7-14 days, though some may take up to 21 days depending on conditions.

Plant height, span and seed sowing depth: Dahlia plants can reach heights of 1-6 feet (30-180 cm), with a span (spread) of 1-3 feet (30-90 cm). Seed sowing depth is 1/8 to 1/4 inch (3-6 mm).

Plant Spacing: Plant Dahlias 12-36 inches (1-3 feet) apart, with smaller varieties at 12-18 inches and larger ones at 24-36 inches.

Row Spacing: Rows should be spaced 2-3 feet (24-36 inches) apart to allow for growth and air circulation.

Trellis or any type of physical support requirement: Taller Dahlia varieties require staking, trellises, or other supports to prevent stems from breaking under the weight of blooms.

Seed to bloom time: From seed to first bloom takes approximately 90-100 days (about 3 months).

For how long does the bloom stays? Individual Dahlia blooms last 4-7 days on the plant, but the overall blooming period extends from summer to first frost.

Flower’s shape and size: Dahlia flowers come in various shapes including pompon, cactus, dinnerplate, and ball forms. Sizes range from 2 inches (5 cm) for miniature types to 12 inches (30 cm) or more for giant varieties.

Life Span: As tuberous perennials, Dahlias can live for many years (5+ years) if tubers are properly stored over winter in colder climates; otherwise, treated as annuals.

Pot size/Container size/Bed size with depth: For containers, use pots 12-18 inches (30-45 cm) in diameter and depth. For beds, prepare areas at least 12 inches deep with good drainage.

Soil type: Dahlias prefer fertile, well-drained loamy soil rich in organic matter. A recommended mix is 50% garden soil, 30% compost, and 20% perlite or sand for drainage. Ideal pH is 6.0-7.0 (slightly acidic to neutral).

Daily sunlight requirement and light requirement for germination of seeds:

Plants need 6-8 hours of direct sunlight daily. For seed germination, provide bright indirect light after sprouting, but seeds can germinate in low light initially.

 Water requirement: Water deeply with 1-2 liters per plant every 2-3 days for established plants (2-4 feet tall), increasing to daily in hot weather or for container-grown plants to keep soil moist but not waterlogged.

Companion plants: Good companions include marigolds (for pest control), nasturtiums, lavender, and zinnias.

Does this flower produces fragrance?

Most Dahlia varieties produce little to no fragrance (rate 0-2), though some hybrids have a mild sweet scent (rate 3-4).

Pest types: Common pests include aphids (use imidacloprid or insecticidal soap; organic: neem oil or ladybugs), slugs (metalaxyl bait; organic: beer traps or diatomaceous earth), earwigs (carbaryl; organic: traps with oil), and spider mites (miticides like abamectin; organic: horticultural oil).

Disease types: Diseases include powdery mildew (fungicides like myclobutanil; organic: baking soda spray), botrytis (chlorothalonil; organic: improve air circulation and remove affected parts), and viral infections (no cure, destroy plants; organic: prevent with clean tools).

Essential Nutrients:

Essential nutrients include nitrogen (5-6%), phosphorus (10-24%), and potassium (10-24%) in a low-N formula like 5-10-10 or 6-24-24. Organic sources: compost (balanced), bone meal (high P, 3-15-0), blood meal (high N, 12-0-0), and fish emulsion (5-1-1).

Fertilizer Application Rate: Apply 100-200 grams of organic fertilizer like compost or bone meal per plant initially, then 50 grams every 4-6 weeks. For products like Dr. Earth Flower Girl, use 100-200 grams (1/2-1 cup) per plant every 4 weeks.

Fertilizer requirement for growth (chemical fertilizer) and application rate according to plant size:

Use low-nitrogen chemical fertilizers like 5-10-10 at 10-20 grams per plant for small (1-2 ft) plants every 2-4 weeks, increasing to 30-50 grams for larger (3-6 ft) plants, diluted in water for foliar or soil application.

Health benefits for human:

Yes, Dahlia tubers contain insulin for blood sugar stabilization in diabetes, antibiotic compounds, and extracts may aid in treating MS, cancer, Alzheimer’s, and inflammation.

Flower’s Edibility: Yes, Dahlia petals are edible and can be used in salads, garnishes, or desserts. Tubers are also edible, cooked like potatoes or yams in stews.

Special Characteristics: Dahlias exhibit a wide variety of colors (except true blue), shapes, and sizes; they are octoploids for genetic diversity; and they attract pollinators while blooming late into the season.

How to take care of this plant to encourage more flowers:

Deadhead spent blooms regularly, pinch back young plants at 8-10 inches for bushier growth, provide consistent water and fertilizer, and ensure full sun exposure.
