Watering. Water sparingly, allowing the soil to dry out completely between waterings. Overwatering can lead to root rot, so it's better to underwater than overwater.
Fertilizing. Feed with a balanced, slow-release fertilizer during the growing season (spring and summer). Avoid over-fertilizing, as cycads are sensitive to excess nutrients.
