How do you plant dahlias?

To plant dahlias, you must choose the right time and planting site, prepare the soil, dig holes and plant the tubers. You need dahlia tubers, sand or peat moss, compost, bonemeal and a gardening trowel.

1. Plant at the right time

   Plant dahlias after the last spring frost when the soil reaches 60 degrees Fahrenheit.

2. Choose a good planting location

   Avoid planting dahlias in locations that are extremely hot or humid. The site needs plenty of direct sunlight with well-drained soil. The soil pH should be neutral or only slight acidic.

3. Prepare the soil

   Improve soil drainage by working manure, sand or peat moss into the soil.

4. Purchase healthy tubers

   Purchase healthy dahlia tubers that show signs of green and are not wrinkled. Avoid breaking or damaging the tuber.

5. Dig the holes

   Dig holes that are just large enough to accommodate the tubers and between 6 to 8 inches deep. Add some compost and bonemeal to the hole.

6. Plant the tubers

   Place the tuber in the holes with the eyes facing upwards. The top of the tuber needs to be just above the soil line. Fill in the hole with soil.

7. Water the tubers at the right time

   Do not water the tubers immediately after planting. Wait until the tuber sprouts to water it.
