Q.Adding Lime to a Mulched Garden
I’ve stopped tilling my garden every year and have converted to a 100% mulched garden space where I pull the mulch back, dig a hole and fill it with compost and manure, plant and then recover with mulch. I know my soil tends toward acidic and I haven’t added lime the past two years. I also use chopped up oak leaves for my mulch, which I understand are acidic. My question is, is it ok to just spread the lime on top of the mulch and let it leach through into the soil, or should I pull all the mulch off down to bare dirt, spread the lime and mix it in? Any help or insights would be very appreciated!

You can move the mulch and mix composted manure and lime, but I would only recommend adding lime if you have had a soil test that recommends that the soil pH is off.
