Some plants like acidic soil because pH affords them good access to nutrients. AS long as your soil provides the proper pH level, it will be sufficient. Avoid raising the pH level further to avoid poisoning your plants. There are pH level testers for soil sold online. If your soil’s pH level is low, you can add materials that contain some form of lime. Ground agricultural limestones are also great additions because succulents love them. Thankfully, you can get hold of most of these ingredients online.
