Hydrangea cultivation is often dominated by asexual reproduction, such as ramet, striping, cutting and so on, especially for varieties or varieties with special ornamental characteristics. Asexual reproduction is an important means to keep the characteristics of offspring consistent with that of mother plants.

Hydrangea cutting propagation method

From April to May, use flowerpots or wooden boxes, put fine sand as cuttings, use the top twigs of eight fairy flowers as cuttings, cut them into a length of 8 cm to 12 cm, each cuttings retain 3 nodes, and leave 1 to 2 leaves, which are directly inserted into the sand bed, covered with plastic film and watered immediately after insertion.

At the temperature of 25 ℃, it took root from 25 days to 30 days, and the seedlings began to move when the white roots turned yellowish brown. After the cuttage is put on the pot, it should be placed in the shade of the flowers for 5 to 7 days, and then moved to the sunny place for cultivation.

Hydrangea embossing breeding method

The family had better use the "high branch crimping method". Select 2-year-old sturdy branches, do circular peeling at 4 cm to 5 cm below the internodes, that is, clip the stem once with scissors, and turn once with scissors at 2 cm below the knife edge, peeling off the cortex between the two edges and exposing xylem. Then tie it into a bag with a plastic film 5cm to 6cm below the edge of the knife, put moss or peat soil in the bag, tie the mouth of the bag tightly, and secure the branches of the bag with a column and irrigate from the mouth of the bag.

In general, pour water into the bag once every 4 to 5 days. From 25 to 30 days, healing tissue will be produced at the ring peeling, and it will take root in about 50 to 60 days. When the young roots change from white to yellowish brown, the mother can be cut off and planted in a pot.

Breeding method of Hydrangea

Separate the rooted branches from the mother plant, pot directly, watering should not be too much, maintain in the semi-shady place, wait for new buds to sprout and then transfer to normal maintenance. Striping propagation can be carried out during bud germination, grow after 30 days, cut off from the mother plant in the following spring, transplant with soil, and blossom in the same year.
