🌱 How to Care for Argentine Saguaro to Prevent Scale Insects?

💧 How to Water

In spring and summer water deeply only when the soil has dried out completely, about every 2 weeks in pots and much less once established in the ground. In winter stop watering, especially in cool weather; wet cold soil causes rot.

☀️ Lighting

Full sun gives the strongest growth and spines; it also accepts light shade. Indoors it needs the sunniest window or a grow light. Acclimate young plants gradually to strong sun to avoid sunburn.

🪴 Ideal Soil

Gritty, fast-draining cactus mix with plenty of pumice, coarse sand or gravel. In the garden it tolerates many soil types as long as water never pools.
