I never do, I just let them get on with it - most shrubs don't have apical domination anyway, so they bush out on their own,, provided they have enough room in the pot to form a good root system over time.

It does depend on the species, but in general the horticultural trade pinches out at least twice to produce well-branched and dense plants that look nice in the garden centres.

I have to agree with Bud. Most cuttings that I take are potted on and I regularly pinch out or cut back just above a leaf joint to make one shoot become two and make them bushy.

Belated thanks to all
