Tips for Growing Coleus Through Propagation

If you are looking to extend your collection of Flame Nettles, you can easily do so either through cuttings or seeds. Here’s how you can propagate them easily like a pro.

Propagation Through Cutting

Select a healthy plant and take a cutting 4-6 inches below a leaf node. Remove the leaves from the lower part, ensuring 2-3 leaves at the top. Place the cutting in the rooting hormone and place it in a container with good potting mix. Place it under a bright, warm area after covering it with a plastic bag. Be sure to water the cutting until the roots are formed. Within 2-3 weeks, roots are formed, and you can transplant them to pots or garden soil.

Propagation Through Seeds

Begin this process 8-10 weeks before the last frost. Sprinkle the seeds in a seed tray with a good potting mix and press them lightly into the soil. Cover the seed tray with a plastic bag to keep it moist and warm. It takes 21 days for germination and 3-4 weeks of warm weather for fully grown plants.  Once shoots are formed, you can transplant them outdoors or into individual pots.

Using the cuttings method is ideal for fast results, preserving certain varieties, and overwintering, whereas propagating through seeds ensures production of many plants at once and the development of new color variations.
