Soil testing in garden - ph test strips/vials vs electronic meters?

Hi,

Am planning a lot of planting in a new garden, have been advised to test the ph levels to help me narrow down plant choices.

There seem to be various potions - kits with ph strips or little vials, or electronic probes. I'm leaning towards the electronic probes, as can reuse and test in as many locations as I like - plus might also be useful for testing water levels of houseplants?

Don't need super accurate readings, just a good idea of how acidic or alkaline the soil is.

Any recommendations for which type is best?

Thanks!

 

I bought an Electronic probe some years ago, it works fine for me.
My garden is quite long and the readings change as I go to the top.

 

For anybody wishing to choose a location, or to understand the conditions they have, much information can be found here:

Of course if the plot you have has been cultivated in previous years, the inherent soils may have been modified a little, but the overall conditions will rarely change significantly; it provides the default, to which it will likely return.

 

pH strips or solution give more accurate answers than any probe from a garden centre or Amazon.
Take a sample of soil, in a jam jar or similar, add water and shake, allow to settle and then use either pH paper or pH solution.
Have a look at your your neighbours garden and see what they are growing, if you spot rhododendrons, camellias, heathers etc then the soil is on the acid side of neutral.

 

I use pH papers, but I was given a fancy meter for Christmas. It came with packets of salts to make up calibration solutions, so it's a bit serious. I'll calibrate it, then compare with the pH paper.

 

Remember to take several samples in each area because you can get spots that are different due to for instance when someone has emptied a pot in a spot or where lime has been used.I like the old fashioned kits with test tubes and a dropper bottle of solution, the range is narrower.You can tell a lot from what weeds are growing and what the neighbours have in their gardens. If everyone has Rhododendrons and Camellias it indicates the soil is acid for instance.

 

If you use a probe don't forget to rinse with distilled water between measurements.

 

Exactly - I've had to buy some deionised water (from Tesco) to ensure my fancy new meter behaves consistently. For me, the only reason it's worth it is because I'm trying to get an agar medium to sit in a very narrow range. In the garden, looking at which plants do well is usually enough. It can fool you through - the base sand in people's gardens a couple of miles from me (on coast) is meant to be alkaline from the shells ground up in it. But it only takes a few years of plant waste rotting in it to make it acidic.
