ðą How to Care for Argentine Toothpick Cactus to Prevent Mealybugs?
ð§ How to Water
Water deeply and let the soil dry out completely before watering again -- roughly every 3 to 4 weeks during spring and summer. Cut back drastically in autumn and winter, since overwatering and poor drainage are the leading causes of root rot in this species.
âïļ Lighting
Give it full sun to very bright light. Outdoors, plant it where it gets direct sun most of the day; indoors, a south-facing window is best. Watch for a yellowed stem on plants exposed to intense, unshielded afternoon sun without acclimation.
ðŠī Ideal Soil
Plant in a gritty, fast-draining cactus mix -- sandy soil amended with perlite or pumice works well. Avoid heavy, clay-based soils that hold moisture and encourage rot.
