Right plant in the right place - if your soil is that alkali then keep them in the pot.
If you really must then how alkali is your soil? Most soil in the UK is naturally acidic to neutral.
What I did is have ericaceous soil around the plant, then mixed ericaceous and surrounding garden soil around that. That is less of a shock for the roots. You can apply ericaceous feed/iron seq when needed - good feeding is key. You can tell when they need a feed (normally spring) as the leaves begin to go pale and yellow.
