What Soil Mix Works Best for a Myrtle Geebung?

Well-draining sandy soil with added organic matter for nutrients. Good drainage is essential for Myrtle Geebung to prevent waterlogging, which leads to root rot and fungal issues.

Feed Myrtle Geebung every 8 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.
