Answer: You are not too late to do something with your poinsettias. You may pinch them back by 1/2 and repot the plants in a container that is one size larger than the one they are growing in. If the plants get leggy, you can tie a string around the branches to support them.
Keep them evenly moist and fertilize periodically. The flowers will return this fall or winter depending on the variety and its daylength requirement.
You must have a bright spot for them indoors since they are doing so well. Many people set them outside for summer where the light is better and they can flourish and grow.
Good luck with your plant!
