EASY STEPS TO PROPAGATE HYDRANGEAS
This is best done in spring or early summer when life again begins flowing through the stems.
Gather your supplies
• Rooting hormone powder or gel
• Quality propagating mix
You’ll also need
Clean bypass secateurs; clean plastic pots
Here’s how
STEP 1 If you haven’t done so already, deadhead the flowers down to where you get living stems.
STEP 2 Cut healthy pieces of stem about 15–20cm long, positioning the top cut above a pair of emerging leaves, close to the node, and the boom cut also just above a node.
STEP 3 If lower leaves are mature, remove all but the top 2 and cut these in half to reduce water loss as roots eventually begin to form.
STEP 4 Dip the cuings into rooting hormone gel or powder and insert into pots filled with propagating mix so about a third to a half of
the cuings are buried. STEP 5 Water well and put pots in a protected spot, out of direct sunlight. Keep your cuings moist but not soggy.
STEP 6 Roots should emerge and be strong enough for transplanting to your garden or another pot in about a month.
You can let cut hydrangeas dry out. Even though they go papery, they keep their shape
