ph in my soil

I have just purchased a pH tester. I have tested my soil to find that it is a pH of 5.5. I have some wood ash but I don't know how much to use. I don't know whether it is too late to use it or using it is better now than nothing. Could anyone help me? Thank you in advance.

  • I wanted to grow vegetables. The ash is from our wood burner. It is mostly pallets with the odd branch of fallen timber. I do like the idea of blueberries in a small corner but our veg plot is 60x12 feet so that is a lot of blueberries. I have sown brassicas & beans which both prefer alkaline soil. Am I gardening it wrong or can I change the soil pH that much.

  • Hi, Bracken - The target soil pH for vegetables typically falls between 5.5 and 7.5, although there are a few exceptions.....so yours seems to be satisfactory for most things.

    Wood ash contains a certain amount of potash, this is useful for feeding flowers & fruit.

    Application rate of your wood ash (providing it isn't contaminated) isn't critical as it contains only small amounts  of potash....say 1/2lb per sq yd....you'll need to do the metric conversion.

  • The main reason for the ash was to raise the pH do you think that the 1/2 lb per square yard would do that. The pH of the ash is over 8

  • Your pH level (pH = acidity or alkalinity) can be adjusted by using lime or potash. I feel that the insignificant amount of potash present in wood ash wouldn't make much difference. I think applying lime at the rate of about 1.1/2lbs per  sq yd would be required.

    Having said that, lime is better applied in late winter, not now.

  • Thank you. But do you think that it is better late than never?

  • Which is what I said. image

  • Thanks I am here for advice so none taken. No compost ready yet only just started making it.

  • How much mushroom compost should I get.
