What’s everyone using to make soil acidic?

Hi all, just got a ph tester so I can see what type of soil is around my blueberry plants and the ph needs to be more acidic, I’ve seen a westmoreland one on amazon, just curious to see what everyone else is using?
also how long it’s lasting

thanks

    I think most people with non-acid soil grow them in pots with ericaceous compost

    That’s what I do ... large pots with loam based ericaceous compost.

    If winter comes, can spring be far behind?

    That's what I do too.
    Unless they're in raised beds, if your soil isn't the right pH the only sure way is pots with ericaceous compost and an ericaceous feed (such as Miracle Gro Azalea feed), and if possible rainwater not tap water
    Knowledge is knowing that a tomato is a fruit.
    Wisdom is not putting it in a fruit salad.

    Mine also grown in pots of ericaceous compost (as replies above) because the clay soil in my garden is only slightly acidic (~6-6.5) and blueberries prefer around 5.  Soil pH will always return to it's natural value over time and how long that takes depends on your soil type (ie sandy, loam or clay based.)  If large (50cm or above) pots aren't an option I would suggest an annual surface dressing (5-10cm deep) of ericaceous compost will help.  One other alternative is to use sulphur chips but it may be difficult to get a stable acidity with those.  Advice from the RHS:

    A trowel in the hand is worth a thousand lost under a bush.

    I grow them in tubs with ericaceous compost too but they never seem to look that healthy, until last year I collected some conifer needles which had dropped onto a concrete road behind the garage that I worked at, they were quite decomposed and last summer I used them as a mulch, the blueberries have never looked so good. I looked to collect some more of the wonder stuff but it has all been scraped up and dumped so am looking for other sources of decomposed pine needles for mulching this year.

    How how big of a container is recommended?
     The type I’ve got is ‘blue crop’. If they’ll grow better and produce more fruit in a planter I’ll end up doing the same

    Just add some acid, surely... ;)

    Now where did all my plants go? 

    (Disclaimer: joke. do NOT add acid :) )

    You can bury pots in the ground so it looks like they are normally planted if you like.

    Trying to change soil pH on permanent basis (especially in a small garden) is waste of time. Measure the pH of your soil and grow whats appropriate.
