Water: Dahlia 'Alfred Grille' requires ample water due to its large leaves but is sensitive to overwatering, causing root rot. Water immediately during droughts and ensure good drainage in wet conditions. Seedlings need less water, while mature plants should be watered more on sunny days, preferably at dawn or dusk.

Fertilize: Dahlia 'Alfred Grille' thrives in fertile soil, requiring liquid fertilizer every 10-15 days initially, shifting to a 7-10 day schedule after bud formation. Stop fertilizing once buds show color. Symptoms of nutrient issues include light leaves for deficiency and scorched tips for excess, while dark green leaves indicate appropriate fertilization.

Pruning: Dahlia 'Alfred Grille' benefits from early spring pruning to stimulate blooms and control size. Remove dead stems and thin dense areas for better air circulation. Regular deadheading promotes continuous flowering, ensuring vibrant growth throughout the season.

Propagation: The propagation methods for dahlia 'Alfred Grille' include root division, cutting, and sowing. Root division involves planting tubers at 15℃ and yields multiple seedlings. Cutting is faster, requiring buds at 3-5 cm to be placed in moist sandy soil, with optimal rooting at temperatures above 25℃. Sowing takes longer, with blooms appearing 1-2 years later.
