Time to change the soil of hydrangea

For hydrangea, the best time to change the soil is in spring every year, because its growth is most vigorous at this time. After repotting, it will quickly adapt to the new environment, and the harm to the plant will not be too great. At this time, it is not easily affected by the environment.

How to repot and change soil for hydrangea

1. Before repotting the hydrangea, you must first remove the pot and use a small shovel to move around the perimeter to make it easier to take out the plant. Gently tilt the pot to one side and slowly take it out with one hand. Shake off some of the soil at the roots, but not all of it. The roots should still have a little original soil, which can protect the roots.

2. Prepare a flowerpot of appropriate size that matches the size of the hydrangea. The soil should be loose and easy to drain. It must be disinfected before use. Then fill the pot with soil and plant the plant in the pot.

Things to note when changing the soil for hydrangeas

1. Bring soil : It is best to bring some original soil when repotting, because if all the soil is cleared away, it is easy to damage the root system, and if some of the original soil is brought with it, it will be more conducive to the plant adapting to the new potting soil.

2. Disinfection : If the roots of the plant are damaged during repotting, it is necessary to use carbendazim to disinfect the roots, and then dry them in the sun before repotting.
