We recently bought a dogwood tree and planted it contained by our yard. There be 3 branches that were baggy pretty low so i cut them off and put them within a jar of water. Does anyone how to properly sprout these branches so they will grow roots and i could replant them within the yard?? Should i preserve them inside or outside?? If anyone knows how to do this please agree to me know. Thanks
Answers:    I have have luck with freshly pushing the dogwood branch into dirt and keeping it well watered. It should sprout roots by itself. The knob is keeping it moist at all times for at smallest one month. Good luck!
wait until autumn and plant them surrounded by a cold frame or in a sheltered spot and they should be growing by the spring
