About Chestnut Dioon
Dioon edule is a slow-growing palm or cycad in the Zamiaceae family. It reaches around 2 m tall and 2 m wide at maturity, with evergreen and silver-grey foliage.
Where to grow Chestnut Dioon
Chestnut Dioon suits subtropical and warm-temperate climates and grows best in full sun and part shade or morning sun. It is frost hardy and shrugs off cold winters. It also tolerates salt-laden coastal winds.
Soil & planting
Chestnut Dioon does best in free-draining soil. Plant into well-prepared ground, firm the soil around the roots and water deeply to settle it in.
Watering & feeding
Chestnut Dioon performs well with relatively little water once established. Feed as new growth begins, following the rate on a balanced garden fertiliser. For the first year, favour occasional deep watering over frequent shallow drinks so roots move into the surrounding soil.
Pruning & care
Tip-prune Chestnut Dioon in spring to maintain a dense, shapely habit. For most gardens, maintenance is low maintenance.
Using Chestnut Dioon in the garden
Chestnut Dioon earns its place for a feature or specimen planting and pots and courtyard containers. It is equally at home in the ground or a large pot on a balcony or courtyard.
Companion planting & design
Chestnut Dioon sits most comfortably beside plants adapted to happy on low water and subtropical climate. A small cluster gives stronger visual impact than isolated plants scattered through the garden.
Good to know
