Acidic blueberry soil


im having trouble getting my soil acidic for my blueberry plant in a pot , I have potted it using ericaceous compost which I done last week but when I test the ph levels it’s still saying alkaline 

any advice please?

    I've used several types of ericaceous compost for mine over the years and never bothered to check the pH and they thrive.
    Use rainwater and an ericaceous feed (e.g azalea feed) from Mar-Sept and they'll be happy.
    How are you checking the pH?

  • I’ve always found mine to be very robust..I must admit I’ve neglected mine, over many years.

    The latest incident I forgot to water it in the heat wave and went on holiday came back it was dry as a bone. All the leaves brown and shrivelled….I was sure it was dead.

    As it had come through everything else…i dumped a watering can on, more in hope than anything else and it just sprang  back to life and started producing new leaves within days…now you’d never know.

    So I’d say don’t worry about it!

    How are you testing the pH? Some of the cheap meters available are useless rubbish and you would be better using some thing like this -

  • You can make your own acidic compost if needed and if you can get the right ingredients. Needles or mulch from any of the pines & conifers for a start.

    Have you watered it with tap water, or used tap water in a soil test kit? Tap water is alkaline in many areas. If not, it could be a dodgy pH meter giving incorrect readings.
