Devon, United Kingdom
I have received 5 plug plants of Verbena Bonariensis and they are about 3" tall and very stocky. Why does the grower say they should be potted on before planting in the garden? They are much bigger than the seedlings I have left to grow in situ in the past. Does potting on help plants to grow? I never understand why we are told to pot on and on until plants are a certain size. What happens if one plants plugs straight into a large pot? So two questions really.
