Tips on Growing Dahlias
- Full sun is the ideal location for most dahlias. Need a minimum of 6 hours of sun.
- Delay planting until all danger of frost is over and soils have warmed up.
- Plant seeds about 1/2 inch deep in a pot, pack, or flat. Dahlias normally germinate in 5-7 days at temperatures between 70-80 degrees F.
- Prepare the soil by digging to a depth of about a foot. Mix in compost.
- Plant 3-6 inches deep 18-24 inches apart.
- When the young plants are planted, the upper part of the root should not be less than three Inches beneath the surface.
- Dahlias do not require too rich a soil - except those intended for exhibition. A very rich soil will produce strong stems and leaves and few, ill-formed flowers. A moderately rich, light loam, is indisputably the best soil
- Dahlia plants become massive and need support to prevent plant breakage and loss of large blooms. A stake as tall as the final flower's height should be put next to the plant at the time of planting. Putting in later may damage the flower.
- Start tying dahlias when they are about 1 foot tall, and continue to tie them at intervals of approximately 1 foot throughout the growing season.
Care of Cut Dahlias
- Cut about an inch off the stems of the dahlias before putting in the vase
- You can take the end of a sharp knife and put a tiny hole into the stem, just under the water line. This will let air out and force the water to go higher.
- Dahlias stems are hollow and will clog if there is a lack of fresh water or if the water contains bacteria. So make sure you use a clean vase. Wash the vase thoroughly with soap and water, rinse clean and dry upside down.
- Cut-flower food will help the dahlias last.
- Change the water and plant food every 2 days.
