I have two Pieris, both in pots. One is older than the other and looks OK except for periods of lacklustre which don't last too long. The other is 2 years old and is still the same size as the day I bought it from a garden centre. Such a sorry sight too, about a foot high. It is in a large pot too so has plenty of room to grow. HELP!!
