Advice Urgently Needed

[Stargazer]

Today I have several plants and bulbs I have bought which need planting immediately.
I need to know what sort of soil is best for which plant. My soil is acidic I believe (ie rhododendrons, camellias and similar plants thrive here).
I have some delphiniums that are getting much too large in their pots where I purchased them from a garden centre and need planting out TODAY! Help - advice needed urgently.

They may not like your acid soil.....
