We have had a very large phoeonix which we grew in a barrel for several years. We have just planted it out into a border as it had out grown the barrel. Lots of nice new green growth, but have noticed that in the new tips of new growth in the centre were slightly paler green and when pulled came away in my hand. They appeared to have a pale blue mould bloom. Does this mean the plant is lost. We live in the Isle of Wight so winters are generally very mild. Help please!
