Can you grow hydrangeas in the ground in the North China region?
Do you know about this? The knowledge related to whether you can grow hydrangeas in the ground in the North China region and the detailed explanation of soil cultivation of hydrangeas are introduced in detail below.
Hydrangeas can be grown in two ways: in the ground or in pots. Different cultivation methods result in different hydrangeas, especially in terms of growth speed and the number of flowers. Hydrangeas can be grown in the ground; it's better not to use pots because hydrangeas are a type of shrub flower, and the longer they are cared for, the more vigorous they grow.
When it comes to growing flowers in the ground, the only factor to consider is the low temperature in winter. Because of the huge temperature difference between the north and south of our country, some plants may easily freeze to death in winter due to temperature differences. Considering only the temperature, there are no other factors that can affect plant growth.
For example, in the southern part of our country, the entire South China region, south of the Yangtze River, is suitable for growing hydrangeas in the ground. In spring, around Qingming Festival, you can plant hydrangeas directly in the ground, water them generously, and under normal circumstances, the hydrangeas will take root and grow. Hydrangeas grown in the ground have a fast root development speed and a high survival rate, making them more vigorous than those grown in pots.
In the southern region, you can grow hydrangeas in the ground without considering any factors, and even in winter, there is no need for any protective measures. Hydrangeas grown in the ground can safely survive the winter. This is not the case in the northern regions. In the East and North China regions, it is necessary to take protective measures for hydrangeas grown in the ground during the autumn and winter seasons, otherwise the roots may freeze to death.
Can you grow hydrangeas in the ground in the North China region?
The biggest fear for plants is low temperature. When the soil temperature drops below 10 degrees Celsius, the roots of most flowering plants will freeze to death, and even in the following spring, they will not sprout. Hydrangeas grown in Shandong must be properly protected in winter, and even further north, protective measures must be even better.
Basically, by November each year, the daytime temperature will drop to around 5 degrees Celsius, which is low enough to be fatal to plants. Before the temperature drops below zero, protective measures must be taken for hydrangeas grown in the ground. By autumn, the leaves of hydrangeas will have fallen off, and once the leaves are gone, you can wrap them with plastic wrap.
Use greenhouse plastic film to completely cover the hydrangeas, without leaving any branches exposed. Once covered with film, there is no need to water the hydrangeas in winter when they have no leaves, and there is no need to spend time managing them. First, cover with plastic film, and then cover with cotton blankets, using old cotton blankets to shield them.
In rural areas of the north, you can use straw or other grass materials to completely cover the hydrangeas, and then wait until the following spring when the temperature warms up and rises above 10 degrees Celsius before removing all protective measures for the hydrangeas. Increase watering at this time, and the hydrangeas will grow new leaves and bloom again by summer.
Hydrangeas planted in the north will bloom for a shorter period compared to those in the south. As long as protective measures are taken in winter, even at minus 20 degrees Celsius, there is no need to worry about the roots freezing; they will definitely bloom the following year.
