watering
Maximilian sunflowers require approximately 1 inch of water per week. During the summer months, water more frequently and deeply. Supplement natural rainfall with water from a garden hose or watering can. For best results, water early in the morning or late in the evening so the sun does not evaporate the moisture quickly. Always check the soil to be sure the soil is dry before watering. During periods of extreme heat or drought, it may be necessary to water more frequently.
sunlight
Maximilian sunflowers thrive in full sun, which means that they need 6 to 8 hours of direct sunlight each day. The optimal amount is during the mid-morning to late-afternoon time frame when the sun is highest in the sky. When growing season arrives, aim for a minimum of 6 hours of direct sunlight each day to ensure full growth potential of the flowers. Make sure to monitor your plant for signs of sunburn or sun scald, which might indicate that the sun exposure is too intense and should be reduced.
pruning
Maximilian sunflowers should be pruned lightly once a year, in late winter or early spring. Pruning should be performed when the plant has lost its leaves and is in a resting period. Pruning should be done carefully and only the old stems and flowers should be removed. If the sunflower is grown for its large flower heads, only the centermost flower should be clipped to allow the others to reach full size. Pruning should not be excessive as this can reduce flowering.
