How to Propagate Trumpetflower?
Trumpetflower can be propagated by seeds, cuttings, or division. Successful propagation requires well-draining soil, consistent moisture, and bright, indirect light. For seeds, stratification might be necessary for germination. Semi-hardwood cuttings taken in late summer or division in the spring are effective methods. The difficulty level is moderate, with care needed for the plant's toxicity and sensitivity to transplanting. Propagation steps include: 1) Preparing well-draining soil mix; 2) For seeds, cold-stratify if required, then sow; 3) For cuttings, take 4-6 inch semi-hardwood sections, dip in rooting hormone, and plant; 4) For division, carefully separate roots and replant promptly.
