What Soil Mix Works Best for a Cycas tansachana?
Well-draining sandy soil with high organic matter content. Good drainage is essential for Cycas tansachana to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Cycas tansachana?
Feed Cycas tansachana 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.

Where Should You Plant a Cycas tansachana?
Choose a spot with full sun to partial shade and well-draining sandy soil with high organic matter content. Avoid low spots where water collects after rain.
Cycas tansachana is suited to USDA Zone 13a.
Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.
How Far Apart Should You Plant a Cycas tansachana?
Cycas tansachana can spread to about 4 ft (1.2 m) and reach about 6 ft (2 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.
