To decide whether or not to remove stem shoots, consider the following:
1. Allowing stem shoots to develop will change the appearance of the plant to a bushy or shrubby shape. It may initially inhibit (but not stop) flowering, but can ultimately improve flowering performance as every rosette will now be producing inflorescences.
2. Stem shoots are often targeted by pests and diseases because these can be difficult to detect or easily overlooked where shoots are forming. The softer plant tissue of a small shoot is also more vulnerable to attack. Also, they are closer to where ants and aphids normally operate.
