How to grow hydrangea? Master these tips to grow it easily

Hydrangea, also known as grass hydrangea and shade hydrangea. It is best to repot once every year in early spring, replacing with fresh potting soil (half leaf mold and half garden soil mixed with a small amount of sandy soil). When repotting, remove part of the old soil and rotten roots, and prune appropriately. Hydrangea likes fertilizer; during the growth and development period, generally apply a thin, well-rotted liquid fertilizer once every half month. To keep the potting soil consistently acidic, add 100 g of ferrous sulfate to every 50 kg of liquid fertilizer and use it for watering. Applying 1-2 additional doses of potassium dihydrogen phosphate solution during the bud stage will make the flowers larger and more brightly colored. Hydrangea leaves are relatively large and bulky, so the plant needs a lot of water. Apart from winter, when temperatures are low and water must be strictly controlled, watering in spring, summer, and autumn should be plentiful so that the potting soil stays consistently moist; especially in the heat of summer, even more water is needed. From May to the end of August, it is also necessary to spray water on the leaf surface once a day or every other day. Because hydrangea has fleshy roots, too much water easily causes root rot, so watering should not be excessive. After rain, promptly pour out any accumulated water in the pot. After September, as the weather gradually turns cool, gradually reduce the amount of watering so that the branches grow strong and sturdy, which helps winter dormancy. Before Frost's Descent, move it indoors and keep the room temperature at around 5°C to encourage dormancy. Before winter begins, remove the leaves to prevent them from rotting. Starting in mid-December, move it gradually to a sunny spot and raise the temperature to 15°C-20°C to promote the growth of branches and leaves, then move it outdoors after Grain Rain the following year. Because hydrangea flower heads are too large, supports should be set up and tied in time; this not only keeps the flowering plant standing upright but also makes the plant look fuller.
