How long does it take to grow?
Poinsettia seeds take 10-15 days to sprout. Foliage blooms are triggered by summer heat and will last until winter.
Why haven't my seeds sprouted?
Some seeds may fail to germinate (this is nature). If sprouts don’t appear in 3-4 weeks, the seeds may have been planted too deep, growing medium is too dry or wet, or temps are too low. In dry climates or during cooler months, consider creating a greenhouse effect by placing the empty grow medium bag over the planter. Punch a few holes for ventilation. Remove the bag once sprouts are 1” tall. Amaranthus Poinsettias prefer warm weather and dry growing conditions. If temps outside drop below 55°F, remove planter from window to prevent cold damage.
How much sun will it need?
Poinsettias thrives in temps between 65°-80°F and with at least 6 hours of direct sunlight (an unobstructed south or west-facing window is best). Starting in Mar-Sept will provide longer days and thus optimal light. If starting during cooler months, it’s recommended that you supplement natural light with a grow light (fluorescent or LED). Amaranthus Poinsettias prefer warm weather and dry growing conditions. If temps outside drop below 55°F, remove planter from window to prevent cold damage. Do not deadhead or shear back this plant or you may lose the colorful tops. Herbs require at least 6 hours of direct light daily, and should be put in an unobstructed window that faces south, west or east (southwest is the best option). During winter months—or if you don’t have an unobstructed window—you can supplement with a grow light.
My sprouts seem weak?
If plant appears weak and spindly, there is either not enough light or temps are not in the optimal range. Try a different window or consider supplementing with a grow light. During the outdoor growing season you can place the planter outside temporarily to jump start your plant after it has sprouted (just make sure to bring the planter indoors if it rains). Do not deadhead or shear back this plant or you may lose the colorful tops.
I'd like a bigger, traditional poinsettia plant. Can I transplant this outside?
This waxed planter is designed to grow a small Amaranthus Poinsettia plant; however, you should transplant it into a larger pot or the ground for a larger and more colorful plant. Transplant outside into a location with full sun after the threat of frost has passed, and sprouts are no more that 4” tall. Prior to transplanting, harden off plant for 5-7 days by placing it outdoors in partial sun during the day, and bringing it indoors at night. Prepare the location by digging a hole about twice the size of the plant. If the soil needs amending, purchase a fertilizer and follow it's instructions. Remove root ball from kraft planter as carefully as possible to prevent root damage. To do this, you may need to cut the kraft planter. Place plant in hole, fill with soil add touch of water (or nutrient solution) and gently tamp.
