Rooting Gymnocalycium or any other species after shipping and the drying out of its root system requires a careful approach. Here are a few tips to help the plant recover:
Inspection of the root system: After shipping, carefully inspect the roots. Remove any dry, damaged, or rotting sections with a clean knife or scissors. It’s recommended to treat the cuts with activated charcoal or fungicide to prevent infection.
Drying the roots: If damaged root parts were removed, allow the plant to dry in a dry, shaded place at room temperature for 1-3 days to let the cuts heal.
Using root growth stimulants: Before planting, you can soak the roots of Gymnocalycium in a root growth stimulant solution, such as “Kornevin” or similar products. This will speed up the formation of new roots.
Proper substrate: Use a special cactus substrate with good air permeability and drainage. A mixture of sand, perlite, and leaf soil, or ready-made succulent soil, is suitable. Ensure the substrate is dry before planting.
Planting and watering: Plant the Gymnocalycium in the prepared substrate and do not water it for 1-2 weeks. This will give the roots time to adapt and prevent rot. After this period, start watering the plant in small portions to stimulate rooting.
Temperature and lighting: Place the plant in a warm, but not hot, area with diffused light. Direct sunlight can burn the weakened plant. The ideal temperature for rooting is 20-25°C (68-77°F).
Humidity control: Avoid high humidity during the rooting stage. Water very moderately, only when the substrate is completely dry.
Patience: The process of rooting cacti may take several weeks or even months. Be patient and do not try to speed up the process by overwatering.
By following these tips, you can successfully root Gymnocalycium after shipping and restore its root system.
