The latest cultivation methods and precautions for hydrangea

Hydrangea, also known as the eight-immortal flower, is a flowering plant in the family Saxifragaceae. The flowers of the hydrangea have very high ornamental value, and hydrangeas can be seen in all major gardens. Hydrangea also has significant medicinal effects, as its roots, leaves and flowers can all be used medicinally. It has the effect of treating palpitations from heart heat and restlessness. So how should hydrangea be cultivated? And what precautions are there? Let's take a look together below!

1. Soil selection

Before cultivating hydrangea, the first thing we must do is choose the soil well. Soil is very important for the growth of hydrangea. Before cultivating, we should prepare a growing soil suitable for hydrangea using leaf mold, garden soil, cake fertilizer and various other materials. The growing soil must ensure good drainage, be rich in nutrients and be slightly acidic in pH, so as to ensure the normal growth of hydrangea and avoid it being affected.

2. Reasonable fertilizing

Hydrangea has a very large demand for nutrients during growth, so we must do a good job of fertilizing when planting. During the growing period of hydrangea, fertilize about once every half a month. Control the amount of fertilizer and the nutrient ratio in the fertilizer well. An appropriate amount of ferrous sulfate and other substances can be added to the fertilizer to avoid unsuitable pH affecting growth. Then before flowering, we should also appropriately supplement hydrangea with substances such as superphosphate to increase the flowering rate and ornamental value of hydrangea.

3. Proper watering

Hydrangea's demand for water is no less than for nutrients. So we should also pay attention to proper watering. In seasons such as spring and summer, water at least once a day to keep the soil moist and prevent the soil from being dry and lacking water. After autumn arrives, we should appropriately reduce the amount and frequency of watering. Water about once every half a month to avoid frost damage to hydrangea caused by too low temperatures, and it can also prevent excessive water from causing root rot in hydrangea.

4. Light control

When cultivating hydrangea, pay attention to ensuring good air permeability in the garden and provide an appropriate amount of scattered light for the growth of hydrangea. The temperature should not be too high. Be careful not to let the sun shine directly on hydrangea, otherwise hydrangea will show yellow leaves and withered leaves. So in summer, we should do a good job of shading, but we should also ensure an appropriate amount of light, otherwise it will affect the flower bud differentiation of hydrangea.

5. Precautions

During the growth of hydrangea, we should pay attention to doing a good job of pruning. When the branches of hydrangea grow to about 12 cm, pinch them appropriately, trimming off the tips of the branches to promote the growth of side branches of hydrangea. Then when the side branches grow to about 9 cm, pinch them again, that is, trim off the tips of the side branches. This can improve the overall ornamental value of the hydrangea plant.

The above is a brief introduction to the cultivation methods and precautions for hydrangea. The cultivation methods for hydrangea are relatively simple, but it should not be managed extensively either, otherwise it can easily lead to cultivation failure. That is all for today's introduction. This article is for reference only. Thank you all for reading and supporting.
