Water: Water is crucial for developing gladioli 'Alaska' flower spikes. The plant needs moderate watering, approximately 2.5 cm (1 inch) weekly. Excessive or insufficient water can stress the plant, harming its health and flower production. Maintain soil moisture by watering every 7 to 10 days.

Fertilize: The gladioli 'Alaska' thrives with proper fertilization. Begin once the plant reaches 15-20 cm (6-8 inches), using a balanced fertilizer a month before flowering. When flower spikes hit 15 cm (6 inches), apply potassium-rich fertilizer biweekly, ensuring fertilizers don't contact the plant to prevent burns.

Pruning: Gladioli 'Alaska' thrives with proper pruning, ideally in early to late spring. Trim spent flowers and cut yellowing foliage to ground post-flowering. Regular pruning enhances aesthetics and air circulation, reducing disease risk. Check local gardening guides for specific timing adjustments.
