Apple Blossom Dahlia Care

Apple Blossom Dahlia care involves watering it twice or thrice every week and misting it frequently. It should be grown in acidic soil with pH 5.0-7.0. It grows best in full sun and high humidity. The humidity must be around 75-85%. It should be fertilized every 3-4 weeks with liquid fertilizer. Its growth zones are 8 and above.

Water Requirements

This pretty plant should be watered 2 to 3 times every week. The key rule for its watering schedule is to check the dryness of the soil. You should allow the soil to dry a little between waterings to save the apple blossom dahlia tubers from rotting. This plant may need extra watering on hotter days. You can overflow the plant with water as long as an excess of it is draining out of the pot. Never over-water your Apple Blossom.

Soil Requirements

This plant does not fuss over soil type. It grows well in well-drained, fertile soil. Acidic soil is a plus point. The pH level of its growing medium must be maintained between 5.0 and 7.0. This Dahlia species thrives in organic soil. You can add rotted manure to its soil from time to time for replenishing the nutrients.


Apple Blossom Dahlia loves full sun. They thrive in 6 to 8 hours of sunlight exposure. However, they also grow perfectly fine in partial shade as long as the morning sun shines upon them. With that being said, you can place your Apple blossom plant in an east-facing window, where it will be safe from the hot afternoon sun.

If you are over-fertilizing it, this plant will have weak tubers or little blooms. In some cases, it does not bloom at all!
