Softwood cuttings I think, go to the rhs website and enter name, then you will get all the information you need

I've just had a look and it says:-

"The best method for propagating photinia cultivars, such as those of P. × fraseri including ‘Birmingham’, ‘Redstart’ and ‘Red Robin’, is by softwood cuttings in early summer or semi-ripe cuttings in summer and autumn.

You can also grow species, such as P. villosa and P. davidiana, from seed, sowing in spring after stratification."

Personally I find a get a better chance of success with semi ripe cuttings in summer/ early autumn

can you explain what you mean by the term semi ripe,? cuttings, and i will take cuttings in early summer,

thanyou
