There are rose people. There are orchid people. And then, there are hydrangea people. We all know to which group of gardeners we belong. Those that prefer the old-fashioned, romantic beauty of the hydrangea flower are always on the lookout for new ways to create even more hydrangea to grow. Propagating hydrangea from cuttings is very easy and there are several ways to do it. Some people have had success rooting cuttings in water. The most efficient and successful way, though is to place them in a pot of soil.
Cut a stem from the hydrangea. Choose a green wood stem that is non-flowering and cut close to the base. Make sure to cut at least 2 inches below a leaf node.
Cut the stem into pieces, right above the leaf nodes, being careful not to cut into the nodes. Your cutting should be about 5 inches and have two leaves. Using sharp scissors, cut the leaves in half, cutting crosswise.
Mix together equal amounts of peat moss, and sand and fill the pots to within 1/2 inch of the top.
Fill the pan or tray with water, so that the water will reach half way up the sides of the pots, and place the pots into the water. Allow them to sit in the water for at least an hour, or until the top of the soil is wet.
Dip the cut ends of the cuttings into the rooting hormone, 1 to 2 inches.
Create a hole in the soil, with a pencil or your finger, deep enough for the cutting to be inserted up to the leaves. Place the cut end of the stem into the hole and pack the soil around the base.
Mist the cuttings well, with the misting bottle, three times per day for the first week. After that, allow the soil to dry out a bit prior to misting and then mist just until the soil is moist. Stick your finger into the soil and if the top one inch is dry you should mist the cuttings.
Place the pots in a sunny or partly sunny location until established. Your cuttings should root within three to four weeks
