Question
if a young sprout's tip is cut off will it grow back?

Answer
Greetings!

Your question makes me think in the terms of grass, your lawn. People cut their grass and it still keeps growing. The grass is young sprouts and the tips are cut off during the mowing process and it keeps grows and does not die. Many times when the tip is cut off more tips are created, thus makes the plant bush out even more by putting more alternate heads from the first head of the young sprout. You did not indicate what type of plant you were inquiring about, so it is difficult to give you a more precise answer.

Be In Joy!
