What Dahlias are Best Suited for Growing Indoors
There are many types of dahlias that are suited to growing indoors, but certain varieties are better than others. The following are some of the best choices for indoor gardening:

How to Start a Dahlia Tubers Indoors
There are many ways to start dahlias indoors. One method is to take a standard pot and place the root ball in the bottom of the pot, filling it up with soil until it is level with the top of the pot. Then water the plant well and keep it watered throughout the growing process. Another method is to purchase started plants from a local garden center or online.
There is no better way to start dahlia tubers indoors than by using a propagation method called layering. This technique involves planting tubers in small groups of three to six, spaced one to two inches apart, and then covering them with soil. The next day, water the plants well and wait for the flowers to bloom. When they do, take the flowers off of the plants and replant the tubers in larger groups. Keep watering and fertilizing until the plants are large enough to be transplanted outdoors.
How to Grow Dahlias Indoors
To grow dahlias indoors, start by purchasing a few young plants from a nursery or garden center. Dahlias like warm temperatures and partial sunlight, so placing them in a bright window is ideal. Water the plants well and fertilize them every two weeks with a balanced fertilizer recommended for indoor plants. After the dahlias have grown to about an inch in height, transplant them into larger pots. Continue to water and fertilize them as needed. When the plants are large enough, they can be moved outside to enjoy the sun and fresh air.
How to Grow Dahlias Indoors
To grow Dahlias indoors, start by finding a sunny window. Once you’ve found your window, dig up a small amount of soil and place it in a container. Plant the dahlia tubers in the soil and water them well. Keep an eye on them and give them water whenever the top inch of the soil feels dry. Your dahlias should be in bloom within 8 to 10 weeks.
What Dahlias Like in the Garden
Dahlias are perennial flowers that enjoy full sultry sun or partial shade. They like well-drained soil and can be planted in any area of the garden.
Dahlias are one of the easiest plants to start from seed. They like full sun, well-drained soil, and a pH of 6.0-7.0. You can start them indoors six to eight weeks before the last frost, transplant them into the garden four weeks after the last frost, or direct sow them in early spring. Dahlias prefer cool weather and need plenty of water in their growing season; they will do best when transplanted into the garden when soil temperatures are between 50-60 degrees F.
un or partial sun. They grow best in soils that are moist, but well-drained. Dahlias do not do well in areas with high humidity, as this can lead to fungal infections.
Before planting your dahlia tubers, make sure you have a sunny location free of heavy vegetation and debris. Dig a hole large enough for the tuber, adding about 2 inches of fresh soil and setting it upright in the hole. water the tuber well and fertilize it once a month with a houseplant fertilizer diluted to half strength (or use a vegetable food bag filled with compost).
Once your dahlia tubers are established, they will need occasional watering during dry spells and moderate fertilizing during the growing season. Keep an eye on them and removing any dead foliage or damaged tubers as needed.
What to do if the Dahlias Get Wet
If you live in a humid area, your dahlias may get wet during the growing season. This can happen when it rains, or if there is a heavy dew or foggy morning. Dahlias like moisture, but they are also hearty plants that can handle some wetness.
To prevent the dahlias from getting wet, make sure to:
1) Water them sparingly – allow only an inch of water to rest in the potting soil at the base of the plant. Over-watering will cause roots to rot and will promote disease.
2) Avoid fertilizing them until after they have bloomed – fertilizing too early will burn the leaves and promote wilting. Fertilize once a month starting six weeks before your desired bloom time and continuing until two weeks after the flowers have faded.
3) Mulch around their roots –Adding organic mulch around their root system will help keep them moist and discourage weed growth.
