How To Propagate Buddleia

Preparation

Before propagating Buddleia, you'll need to gather a few supplies and choose the right propagation method. To propagate through cuttings, you'll need sharp, clean shears or a knife and a rooting hormone. If you're sowing seeds, you'll need a seed tray, seed starting mix, and a heat mat to maintain the right temperature.

Softwood Cuttings

Softwood cuttings are taken from the new, soft growth of the plant. This method is best done in the spring or early summer. To take a cutting, use sharp shears to cut a 4-6 inch piece of stem from a healthy plant. Remove the leaves from the bottom inch or two of the stem and dip the end in rooting hormone. Plant the cutting in a pot filled with moist potting mix and keep it in a warm, humid environment until roots have formed.

Sowing Seeds

Buddleia seeds can be sown indoors or outdoors. To sow seeds indoors, start them 6-8 weeks before the last frost. Sow the seeds in a seed tray filled with seed starting mix and press them lightly into the soil. Keep the soil moist and warm until the seeds have germinated. Once the seedlings have developed their first set of true leaves, you can transplant them into individual pots.

Semi-Hardwood Cuttings

Semi-hardwood cuttings are taken from stems that are slightly woody, but still flexible. This method can be done in the late summer or early fall. To take a cutting, use sharp shears to cut a 6-8 inch piece of stem from a healthy plant. Remove the leaves from the bottom two or three inches of the stem and dip the end in rooting hormone. Plant the cutting in a pot filled with moist potting mix and keep it in a warm, humid environment until roots have formed.

Conclusion

No matter which propagation method you choose, be sure to provide your Buddleia plants with the right growing conditions to ensure their success. Buddleia prefers full sun to partial shade and well-drained soil. Water your plants regularly, especially during hot, dry weather. Fertilize your plants monthly with a balanced fertilizer to promote healthy growth and flowering.
