Water: Dahlia 'Allan Sparkes' thrives with large leaves, needing ample water but is susceptible to root rot if overwatered. Water promptly during drought and ensure good drainage in rain. Seedlings require less water, while mature plants need increased watering, preferably before and after sunrise or sunset.

Fertilize: Dahlia 'Allan Sparkes' thrives in fertile soil. Apply a liquid nitrogenous fertilizer every 10-15 days initially, then switch to phosphate-potassium as flower buds emerge, fertilizing every 7-10 days. Cease fertilization when buds show color, and adjust based on plant condition indicators.

Pruning: Dahlia 'Allan Sparkes' produces vibrant, large blooms. Prune in early to late spring to remove weak stems and promote growth. Thinning enhances air circulation, while deadheading extends blooming. These practices ensure a healthy structure and vigorous blooms, preparing dahlia 'Allan Sparkes' for optimal growth in the next season.

Propagation: Propagation of dahlia 'Allan Sparkes' includes root division, cutting, and sowing. Root division, conducted in early spring at 15℃, yields approximately five seedlings per tuber.
