How to Propagate Hydrangea? Detailed Guide to Common Propagation Methods
1. Division Propagation
This is best done in early spring before buds sprout. Separate the rooted branches from the mother plant and pot them directly. Do not water too much; keep them in partial shade, and once new shoots sprout, switch to normal care.
2. Layering Propagation
This is done when the buds begin to swell. Growth occurs after 30 days, and the following spring, cut it from the mother plant and transplant it with the soil; it can bloom the same year.
3. Cuttage Propagation
This is done during the plum rain season. Cut off the tender top shoots, about 20 cm long, remove the lower leaves, and the suitable temperature for cuttage is 13-18°C; roots form 15 days after insertion.

Hydrangea is also familiarly known as the hydrangea flower, a flower species with full and beautiful petals. Hydrangea comes in diverse colors and has extremely high ornamental value. Its many colors and fresh hues make it loved by many flower enthusiasts, and in many European countries this flower is mostly planted in courtyards. Today I will bring you hydrangea pictures and then talk about hydrangea cultivation methods.
Hydrangea Pictures Hydrangea Cultivation MethodsI. Hydrangea Cultivation Methods——SoilHydrangea planting requires loose, fertile soil with good drainage. The pH value of the soil is most important for hydrangea planting. Fertilizing with aluminum sulfate makes hydrangea turn blue, while using lime produces the red series of hydrangea.
II. Hydrangea Cultivation Methods——LightHydrangea does not like light; growing in a dark environment every day is more conducive to hydrangea sprouting. When planting hydrangea, keep it away from sunlight; it is best to provide about 60 percent shade.
III. Hydrangea Cultivation Methods——TemperatureHydrangea's temperature requirement is warmth. Hydrangea likes to grow and develop in an environment above 18 degrees; too low a temperature slows hydrangea sprouting. After hydrangea blooms, keep the temperature at around 16 degrees, and the flowering period of hydrangea can be extended even longer.
IV. Hydrangea Cultivation Methods——PestsHydrangea requires attention to pest control. Besides professional insecticides such as mancozeb wettable powder, you can soak cigarette butts in water to water the flowers, which also has a good insecticidal effect.
Hydrangea Cultivation Methods
Hydrangea likes warmth and humidity, is not tolerant of drought, and also avoids waterlogging; it likes a semi-shady environment, is not cold-tolerant, and is suitable for growing in fertile, well-drained acidic soil. The acidity and alkalinity of the soil have a very obvious effect on hydrangea flower color: when the soil is acidic, the flowers are blue; when the soil is alkaline, the flowers are red. Hydrangea is best cultivated in acidic soil (pH 4-4.5 is suitable). Hydrangea likes fertilizer; during the growing period, generally apply a dilute decomposed cake fertilizer solution once every 15 days. To maintain soil acidity, 1%-3% ferrous sulfate can be added to the fertilizer solution. Regular watering with alum fertilizer water can make the plant's branches flourish and leaves green; adding 1-2 applications of monopotassium phosphate during the bud stage can make the flowers larger and more colorful; applying cake fertilizer should avoid the dog days to prevent pests and diseases and damage to the root system.Hydrangea has large leaves and luxuriant branches and leaves, and requires a relatively large amount of water. In the growing seasons of spring, summer and autumn, water sufficiently to keep the potting soil moist at all times. In summer, the weather is hot and evaporation is high, so besides watering sufficiently, also spray water on the leaves every day. Hydrangea's roots are fleshy roots, so watering must not be excessive, and water accumulation in the pot is taboo, otherwise the roots will rot. After September, as the weather gradually turns cooler, gradually reduce the amount of watering. Move it indoors before Frost's Descent, and the room temperature should be kept at around 4 degrees. Before moving indoors, remove the leaves to prevent leaf rot. In winter, it is best to place the plant in a sunny spot indoors, and it is suitable to move it outdoors after Grain Rain the following year.
Hydrangea management is relatively extensive, with few pests and diseases, making it an ideal potted flower that is relatively easy to manage and cultivate. How do you repot, change the soil and prune hydrangea? For potted hydrangea, generally repot and change the soil once a year. Repotting and changing the soil is best done in early March. The new soil is prepared with a ratio of 4 parts leaf mold, 4 parts garden soil and 2 parts sand, plus an appropriate amount of decomposed cake fertilizer as base fertilizer. When changing, prune the plant's root system, cutting off rotten roots, decayed roots and overly long root fibers. After moving the plant into the new pot, press the soil firm, then water thoroughly, place it in a shaded place for about 10 days, then move it outdoors for normal management. To make potted hydrangea have a beautiful crown and bloom more, the plant must be pruned. Hydrangea grows vigorously and tolerates pruning. Generally, after the seedlings survive and grow to 10-15 cm tall, pinch out the growing tips so that the lower axillary buds can sprout. Then select 4 well-sprouted new branches in the middle and upper parts, and remove all the lower axillary buds. When the new branches grow to 8-10 cm, pinch out the growing tips a second time. Hydrangea generally blooms on biennial strong branches; after flowering, the old branches should be cut short, keeping only 2-3 buds, to limit the plant from growing too tall and to promote new shoots. After autumn, cut off the tops of the new shoots to stop the branches from growing, which helps them overwinter. After such pruning, the plant's shape becomes more graceful, greatly enhancing its ornamental value.
Hydrangea propagation is not difficult and it roots easily. It can be propagated by cuttage or division. Cuttage is best done in spring and summer, using one-year-old branches cut into 10-15 cm lengths as cuttings, inserted in a sand bed; roots form in about 20 days, then they are transplanted into pots for cultivation. Division propagation is best done in early spring before the plant sprouts; according to the mother plant's root vigor, it can be divided into several plants, cutting off decayed roots and overly long roots, and transplanting them into prepared pots for cultivation and management, while also pruning the branches.
