I have experimented with root trainers and tall pots for sweet peas and hellebores. I found no difference at all. Repotting was far better...i.e. Not allowing plants to become root-bound.
There is a tendency to leave plants in root training pots thinking they will be fine for longer without planting out. Why is it deemed better to use taller but narrower root trainers instead of growing on into 1 litre pots? Plants in the latter, for me, are much better
