Key points for caring for hydrangea

Hydrangea likes a shady and humid environment and is not cold-resistant. When grown in an environment of extreme heat and direct sunlight, the leaves will become scorched and yellow. Hydrangeas grown in the open field or maintained on open balconies are susceptible to frost and death in autumn and winter. If it overwinters in a greenhouse, it can remain evergreen. In short, each season has different maintenance points. Let's take a look at them separately:

spring

When the plants wake up in spring, they need to prune dead branches and repot and change soil in time.

Start fertilizing 2 to 3 weeks after repotting, and apply thin liquid fertilizer mainly composed of nitrogen once every 15 to 20 days to promote the growth of branches and leaves.

Watering should be based on the dryness and wetness of the potting soil, usually once a week.

Summer and Autumn

Summer and autumn are the time when flowers bloom and fall, so maintenance is particularly important.

In summer, place the plant in semi-shade to prevent the leaves from being burned by the scorching sun. After autumn, you can move it to a bright place and provide appropriate light supplement.

Apply organic fertilizer 1 to 2 times before and after flowering to promote green leaves and abundant flowers.

Control watering and keep the soil moist. Water evaporates quickly in summer, so water once in the morning and once in the evening. Prevent water accumulation in the potting soil to prevent the fleshy roots from rotting due to excessive water.

After the flowers fade, cut off the flower stalks and dead leaves in time to ensure the beautiful appearance of the potted plants.

winter

When winter comes, keep warm. For plants grown in the open field, add thick soil or cover with plastic bags to keep warm; potted plants should be placed on a south-facing balcony, in a warm place that is well ventilated but not affected by cold winds.

Hydrangea will enter a dormant period in winter, and the above-ground parts will dry and fall off, but the rhizomes will still survive and will grow branches and leaves again next year.
