Complete Care Guide
### Dahlia Care Guide
Dahlias require full sun exposure and well-drained, fertile soil to thrive. Plant tubers in spring after the danger of frost has passed, spacing them about 18 to 24 inches apart. Water regularly to keep the soil moist but not soggy, especially during dry spells. Fertilize monthly with a balanced fertilizer to promote healthy growth and abundant blooms. Deadhead spent flowers to encourage continuous blooming throughout the season. Support taller varieties with stakes to prevent breakage. As dahlias are not frost-hardy, tubers should be dug up and stored indoors in colder zones during winter. Regular monitoring for pests like aphids and slugs is recommended, although dahlias generally have low maintenance needs.
