Saucer Magnolia - Soil ph
I have a Saucer Magnolia that I decided to put river pebble under. My husband just picked up the rock and it just occurred to me that the soil ph would change. I have read that Saucer Magnolias like acidic soil and will not tolerate alkaline soil. I am afraid the rock will make the soil too alkaline. Would really appreciate your thoughts and suggestions on this. Do any of you have river pebble under your Saucer Magnolia?
