|My friend up north wants to know if she can propagate a hydranga tree by a cutting of a branch. If so, do you put it in water or directly in some dirt or into the ground. Thank you......|
|You can propagate hydrangeas with cuttings. In Florida, you can do this in the fall months. I don't know where your friend lives "up north" but early summer might be a better time to take cuttings in cold climates.
First, select a stem (or several) for cutting. In early Fall, (or mid-summer, up north), choose a stem that is at least 6 inches long, has no flower or flower buds, and is the current season's growth. A new growth stem will be a lighter green than old growth.
Once you have selected your stems, use a sharp pair of shears to cut each stem, making the cut just below a leaf node. A leaf node is where a set of leaves are growing. The hydrangea cutting should be at least 4 inches long and should contain at least one additional set of leaves above the selected leaf node.
After taking your cuttings, strip all but the top most set of leaves from the cutting. The cutting should have only two leaves left at the top of the cutting.
You can dip the cut ends of the cuttings in rooting hormone if you have any on hand. While rooting hormone will increase the chances of success, it isn't absolutely necessary.
Stick the cuttings into damp potting soil. Cover the pot with a plastic bag, making sure that the bag does not touch the leaves of the cuttings.
Place the pot in a sheltered location out of direct sunlight. Check the hydrangea cuttings every few days to make sure the soil is still damp. In about 2-4 weeks, the cuttings will be rooted and you can plant them in individual pots or directly in the garden.
