Why won't my Crinodendron Hookerianium flourish.

They are shade loving plants, and thrive in acid soil. If it is in the sun, that probably explains it. Have you got acid soil??

They also need constant moisture at all times of the year. Our Crinodendron was doing OK until the big freeze up at Christmas time which lasted for two weeks. The ground froze up and the shrub was starved of water for this period. After the freeze our shrub started to lose its leaves and just this week I noticed that its extensive number of flower buds are starting to fall. I am told that the shrub is possibly still alive but, at the moment, I am not convinced. Pity as we have had it for quite a number of years.
