Methods for Propagating Hydrangeas
The three main method for making more hydrangea are base cut , ground layering , and division . Let ’s break in them down to discover which one is the good for you .
1. Stem Cutting
When propagating bystem cuttings , a section of an actively growing stem is cut from the industrial plant in outpouring or former summer and planted in moist potting dirt . In a few weeks , the cut originate roots , and a raw plant develop . Maintaining consistent warmth and humidity around the cutting until it produces new root is significant . Stem cuttings are usually the most prolific method acting of propagation .
Best for : Producing many raw hydrangea plants .
2. Ground Layering
This easy method acting is similar to stem turn cuttings , but the stem are still attach to the main plant to propagate it . You just bend a bow from the parent plant down to the ground , and bury a part of the stem in a shallow deep . Roots work on the buried destiny of the prow , and then the stem can be split up from the parent flora . The amount of blank space near the parent plant limits strand layering propagation .
Best for : build only a couple of Modern plant life .
3. Division
tranquil hydrangea ( Hydrangea arborescens ) andoakleaf hydrangeashrubs spread to form colonies alternatively of growing clumps like many other hydrangeas . The fastestpropagation methodfor bland and oakleaf hydrangea colony is division , which involves using a sharp spade to fag up a portion of the colony and replanting it in a new locating .

gradation 1 : Using acute , sanitized pruners , snip off a 5- to 6 - inch - long press cutting from the tip of a arm that ideally did not flower last year .
tone 2 : Remove the two downcast leaves from the cutting . This disclose the leafage knob , from which new roots will go forth .
Step 3 : Cut the remaining leaves on the cutting down to half their size of it . Reducing the foliage size lessens the pressure on the plant to support the leafy growth . rather , the plant can crusade resources toward form new roots .
Step 4 : Dip the cut end of the stem cut intorooting endocrine . Although rooting hormone is not essential , it speeds up the rooting process . Plant the cutting in moist potting soil , burying the two lowest folio nodes .
footprint 5 : Water the sight well and allow it to run out thoroughly . Then , wrap up it with clear plastic , such as a plastic handbag . Add bet if needed to prevent the charge card from touching the cutting . target the cut in anindirect short locationindoors — not in direct sunlight . Do not water again unless the top of the soil is juiceless .

Remove the plastic cover and admit the plant to carry on expanding its young root organization . Repot as involve , plant the raw hydrangeain a larger container or transplanting it into the landscape painting .
Propagating Hydrangeas by Ground Layering
All hydrangea can be disseminate by ground layering . plant life with long , flexible theme are easy to base stratum . Spring or early summer is the best metre to propagate using this method acting .
footfall 1 : Select a long , flexible stem on the outer edge of a hefty , actively growing hydrangea .
pace 2 : Gently flex the branch toward the ground so that a 5- to 6 - inch - retentive portion of the offshoot near the center of the length touch the ground . polish off the leaf in this 5- to 6 - in - long segment . Removing the leave exposes the leaf node . newfangled source will forge at the foliage nodes .
Step 3 : Use a sharp tongue to gently come up a thin layer of bark off the undersurface of the branch where the leaves were removed . Be deliberate not to disturb the leaf node .
footmark 4 : Dig a 2 - inch - inscrutable oceanic abyss about 6 inches long . Place the prepared portion of the hydrangea stem in the deep and cut across it with soil . Place a heavy gem or brick on top of the swallow offshoot to keep it in shoes .
stair 5 : Keep the buried share moist and disturb it as little as possible . Two to three weeks after burying the ramification , check for new roots . Remove the stone or brick and gently move away soil in the oceanic abyss . If you do n’t see new roots , softly tug on the branch . If it extend electrical resistance , new tooth root have formed .
