pruning tecomaria capensis

Not knowing much about this plant, I don't know if it flowers on new or old growth. You do need to check this out before pruning because doing it at the wrong time will affect flowering.

I never prune anything with a frost on it or if one is likely.With this plant coming from a warmer country, that could be even more important to think about.
Sorry I can't be of more help.

To keep this shrub clean and tidy, it must be pruned back in late winter to promote new growth and flowers. The application of a balanced fertilizer after pruning will enhance the growth and flowering

I wouldn't call it 'late winter' yet, would you? Better to be safe than sorry. Leave it until YOUR 'late winter'.
