What are the latest breeding methods of hydrangea?

Hydrangea, also known as hydrangea, red, pink, blue, white and other colors. Hydrangea is a beautiful indoor ornamental flowers, Saxifraga family, Hydrangea genus shrubs, plant height 30 cm to 120 cm. Leaves opposite, ovoid, leaf margin serrate. Umbrella inflorescences terminal, spherical, flowers have green white, pink, pink and light blue. Flowers bloom from May to July. Hydrangea cultivation is often based on vegetative propagation such as ramets, layering, cuttings, etc., especially varieties or varieties with special ornamental characteristics. Asexual propagation is an important means to keep the characteristics of offspring consistent with those of mother plants.

Hydrangea cutting propagation method

From April to May, use flowerpot or wooden box, put fine sand as cutting bed, use top shoot of hydrangea as cutting ear, cut into 8 cm to 12 cm length, keep 3 nodes for each cutting ear, and leave 1 to 2 leaves, directly insert into sand bed, cover with plastic film, water immediately after insertion.

Under the temperature condition of 25 DEG C, roots are formed after 25 to 30 days, and seedlings are transplanted when white roots turn yellow brown. Cuttage seedlings on the pot, to be placed in the shade of the seedlings 5 to 7 days, and then moved to the sun to cultivate.

hydrangea layering propagation method

The family had better use "tall branch layering method". Select 2-year-old healthy branches, 4 cm to 5 cm below the internode for circular peeling, that is, use scissors to clamp the stem and rotate one circle, and then use scissors to clamp and rotate one circle at 2 cm below the knife edge, peel off the cortex between the two knife edges and expose the xylem. Then bind the bag with plastic film at the position 5 cm to 6 cm below the knife edge, fill moss or peat soil in the bag, tighten the bag mouth, fix the bagged branches with upright posts, and irrigate water from the bag mouth.

In general, 4 to 5 days to fill a bag of water. From 25 to 30 days, healing tissue will be produced at the girdling place, and roots will be born in about 50 to 60 days. When the young roots turn from white to brown, they can be cut off from the mother and planted in another pot.

hydrangea plant division propagation method

Plant division and propagation should be carried out before germination in early spring. The rooted branches are separated from the mother plant, potted directly, watered not too much, maintained in the semi-shade, and then transferred to normal maintenance after germination of new buds. The layering propagation can be carried out when the bud sprouts, and can grow after 30 days. In the spring of the following year, it can be cut off from the mother plant, transplanted with soil, and can bloom in the same year.
