Hybrid poplar propagation is a process of growing new trees from cuttings taken from existing trees. This is a relatively simple process that can be done at home with a few basic supplies.

To propagate hybrid poplars, you will need the following supplies:

• Cuttings from healthy, mature hybrid poplar trees
• A rooting hormone (optional)
• A rooting medium (such as perlite or vermiculite)
• A container with drainage holes
• A sunny spot outdoors

Instructions:

1. Take cuttings from healthy, mature hybrid poplar trees in the fall or early spring. The cuttings should be about 6-8 inches long and have at least two or three buds.
2. Remove the leaves from the bottom two-thirds of the cutting.
3. If desired, dip the cut end of the cutting in a rooting hormone.
4. Fill a container with a rooting medium and moisten it well.
5. Insert the cuttings into the rooting medium so that the top two or three buds are above the surface of the medium.
6. Place the container in a sunny spot outdoors.
7. Keep the rooting medium moist but not wet.
8. Check the cuttings regularly and remove any that have died.
9. After about 4-6 weeks, the cuttings should have rooted and can be transplanted into their permanent location.

Hybrid poplars are fast-growing trees that can be used for a variety of purposes, including timber production, biomass production, and erosion control. They are relatively easy to propagate, making them a good choice for home gardeners and small-scale farmers.

Here are some tips for successful hybrid poplar propagation:

• Use cuttings from healthy, mature trees.
• Take cuttings in the fall or early spring.
• Dip the cut end of the cutting in a rooting hormone.
• Use a well-draining rooting medium.
• Place the container in a sunny spot outdoors.
• Keep the rooting medium moist but not wet.
• Check the cuttings regularly and remove any that have died.
• Transplant the rooted cuttings into their permanent location after about 4-6 weeks.
