What type of compost does an olive tree need?

Olive trees do not require compost, but they can benefit from it. Compost can help improve the soil structure and provide nutrients for the tree. If you choose to compost around your olive tree, use a well-rotted compost that is free of weed seeds and pathogens. Apply the compost in a 2- to 3-inch layer around the tree, but avoid piling it directly against the trunk.
