Coconut chips 2-5mm for the perfect Plumeria soil mix. Plumerias love soil with a pH value between 5 and 6. With our organic coconut chips, you get an ideal additive to your soil with a stable pH value of 5.5 - 6.5. Additionally, these coarse chips help aerate the soil because Plumeria roots like to breathe and only feel comfortable when the soil is loose and airy.CONTENT: 10 liters (bulk consumer bag, unpressed)
