The decorative dahlia requires regular watering to ensure maximum bloom. During the growing season, water 1-2 times per week letting the top inch of soil dry between watering. During extremely dry periods, water may be needed more often. Regularly check the soil to determine water needs, the soil needs to be kept moist. For best bloom, make sure to water during dry spells. Avoid oversaturating the soil or waterlogging the roots. When the flowers start to wither, it is a sign that the plant needs more water. In the winter, reduce watering but don't let the plant completely dry out.

sunlight

Decorative dahlias (Dahlia 'Prinzessin Irene von Preussen') need about 6 to 8 hours of full sunlight a day during the summer months. This plant thrives best in full sun and does not tolerate extended exposure to shade. Morning sunlight is preferred, but if that's not possible, then late afternoon is acceptable. During the winter months, when there is less sunlight, they need at least 4 hours of direct light a day.

pruning

To ensure healthy growth and attractive flowering, decorative dahlia plants (Dahlia 'Prinzessin Irene von Preussen') should be pruned regularly throughout the season.

In mid- to late summer, remove 1/3 of the old growth around the perimeter of the plant. Cut stems back to the ground to encourage denser growth and additional blooms. When the foliage starts to fade, cut back the plants to half their size and remove all spent flowers. Mulch around the plant's base for additional protection from cold weather.
