About 4 years ago I bought 3 Paulownia tomentosa. They are planted in different parts of the garden but none have grown more than about 2 meters. Any advice would be welcome.

I think you are right about clearing the area beneath Seaburngirl, that wild marjoram is everywhere. Thank you.

I think they just need time. make sure you water them during dry spells.
I would clear away some of the plants around their bases [leave at least n 18" diameter] as they will be competing for water an nutrients.
see what any one else suggests Ginellie.
