How to Propagate Red Osier Dogwood?

The best way to grow red twig dogwood is by propagating it in late fall using hardwood cuttings. Here are some simple steps that you need to follow to propagate a dogwood plant:

1. From a healthy red twig dogwood plant, take a hardwood stem of around 6 to 9 inches long with a bud near either end of the cutting.
2. Take off side branches and leaves and dip each segment in rooting hormone.
3. Plant the cutting in a pot and place it in a sheltered area. Ensure you keep the soil moist throughout.
4. In spring, move the pot in the open and let it continue growing. 
5. It can take a full year for the cutting to form roots. 
6. Once the roots are established, you can transplant the saplings in an area of your choice that receives direct sunlight with partial shade.

Essential Redwood Twig Dogwood Care Tips 

Red twig dogwood thrives in light and is tolerant of most soils. Here are some of the care tips for red twig dogwoods:

1. Plant dogwood in a location that has support around it and receives direct sunlight with partial shade, especially during winter. 
2.  You can also choose a location on steep banks to control soil erosion.
3. Ensure you remove the old stems every year to keep the best colour on the new stems. 
4. Trim the roots around the plant base to keep the shrub from spreading too much. 
5. Make sure that you use soil that is rich and consistently moist.
6. If you are planting multiple red osier dogwoods, ensure you place them around 8 to 10 ft apart from each other. This helps with good air circulation. 
7. Dogwoods prefer moist soil and thrive in low spots or along ponds or streams. If there is not a lot of rain, water the plant weekly for the first few months. Later, when the plant matures, only water it during the dry spells when there is no rainfall for more than a week. 
8. Avoid fertilising the plant because it is not a heavy feeder. Instead, use organic compost in early spring. 

Tip 
Pair red twig dogwood with plant varieties that can tolerate full sun to partial shade and consistent moisture. Some of the best companions for dogwoods are honeysuckle, lily, chokeberry, and black-eyed susans.
