I have a Dwarf Peach tree that was in a 12" pot when I received it 2 years agp. This year several sprouts have come up from the roots about 1-2" away from the main tree trunk. The leaves on these sprouts are a deep red and are growing fairly rapidly. I cut a couple down but others are coming up. Why are there red leaves on these sprouts, and will the sprouts hinder the growth of the peach tree itself?
