Propagation of Senecio cernuus Gray
Senecio cernuus Gray is commonly propagated through seeds, stem cuttings, and root division.
Propagation through seeds
The plant's seeds can be collected when the seed heads turn brown. Place the seeds in a paper bag and store them in a cool dry place. Sow the seeds in a germination tray or small pots filled with potting mix. Keep the soil moist and maintain a temperature range of 18-25°C. Within 10-14 days, the seeds should germinate, and the seedlings can be transplanted into larger pots or outdoors.
Propagation through stem cuttings
Take stem cuttings from a healthy parent plant and insert them into a potting mix. Keep the soil moist and maintain a temperature range of 18-25°C. Within 2-3 weeks, the cuttings should develop roots and can be transplanted into larger pots or outdoors.
Propagation through root division
Senecio cernuus Gray can be propagated through root division by dividing larger parent plants. Carefully remove the plant from the soil and separate the roots into smaller sections. Replant the smaller sections into pots or outdoors and keep the soil moist.
