Growing Instructions:
-
Dahlias are shipped as tubers and should be planted immediately upon arrival.
-
Dahlias require at least 8 hours of full sun to thrive and bloom abundantly.
-
Dahlias are cold-sensitive and should not be planted until after all danger of frost has passed and soil has warmed to 15°C (60°F).
-
For dahlias to thrive and bloom abundantly, they should be planted in a location that receives 8 hours of direct sun in fertile, well-draining soil that is rich in organic material. Avoid low lying areas that can get water logged as this can lead to tuberl rot.
-
To improve soil structure and fertility, you can amend the soil prior to planting with 5-10 cm (4-6") of well-rotted manure or compost and a light application of bone meal.
-
Dig a hole 10-15 cm (4-6") deep and place the tuber on its side, horizontally, with the growing eye facing up. Once in place, refill the hole with soil. The top of the tuber, where the sprout emerges, should be positioned no more than 2.5-5 cm (1-2”) below the soil surface when the hole is filled in. Fill in around the tuber, firmly pressing down the soil so it is even with the surrounding ground. Make sure there are no air pockets in the soil.
-
Dahlias can become large and should be spaced 30-45 cm (12-18") apart.
-
Do not water until dahlia shoots emerge through the ground. If you water before shoots are visible, this can lead to tuber rot.
-
Water needs: 2.5 cm (1") of water per week during growth. More may be required if the weather is hot and you are experiencing drought-like conditions.
**Not ready to plant? If you are not able to plant the tuber(s) upon arrival, open the package and check if the peat moss, or other packing material is moist. If it is barely damp, or dry, add a little room temperature water and close the package and place in a cool (not freezing), dark location. If longer than a few days, remove the root(s) and plant in a container with moistened potting mix and place in a cool (not freezing), dark location. Storing the tubers for an extended period of time will reduce their viability.
- Planting Depth: 10 - 15 cm (4 - 6")
- Plant Spacing: 10 - 15 cm (4 - 6")

Instructions for Nutrient Care:
Feed plants SUPERthrive once per week. Mix 1.2 ml (1/4 tsp) per 4L (1 gallon) of water in a watering can and apply solution to the base of the plants.
