To learn how to care for a potted hydrangea plant, you first have to take into account some aspects of planting it.
- When you bring your new hydrangea home, prepare its new large pot , which should be at least twice the size of the plant’s root ball.
- Bury it with the appropriate substrate, which we will discuss later, right up to where it was in its nursery or store pot.
- Water the land abundantly.
- Keep the plant covered from the sun for a few days while it acclimatizes.
Light and location for hydrangeas
How much sun do hydrangeas need? Virtually all hydrangea species agree that they need a very bright environment, with at least 5 hours of light a day . They especially like the light that comes from the East, that is to say, that of the morning, since they do not tolerate direct exposure to a very intense sun well, being better to keep it covered from the hours of light of noon and afternoon.
Thus, your hydrangea will need a lighted room where the plant receives either direct sunlight in the morning, provided you are in a mild climate, or indirect exposure throughout a good part of the day. In very hot climates, a semi-shade location may be more than adequate for these plants.
Regarding the pots, this is also one of the most important points in the care of indoor hydrangeas. The first thing is that it is necessary that you have your hydrangeas in large pots , about 50 cm in diameter, since, if the roots do not have enough space to develop and look for nutrients, the plant will not flower or even dry out. It is also necessary that the pot has drainage holes, and it could help to have wheels or the like to move it if you are going to have to move it to different locations during the morning and afternoon.
Watering the potted hydrangeas
We go on to detail another very important point in the care of these plants: how to water a potted hydrangea?

Indoors, water it when the top layer of the substrate has dried, applying a deep watering and removing the excess water from the plate or tray at the base of the pot. In warm months and if the weather is hot, the hydrangea may need daily watering.

If this is the case and you notice that your hydrangea turns yellow, water your plant with rainwater or decalcify the water , letting it rest for about 24 hours, before watering the plant with it.

Potted hydrangeas need a substrate rich in nutrients and with great drainage , that is, one that is light. Use a mixture with vermicompost and peat , which will give the plant the nutrients it needs.
Also, hydrangeas that are not white can change color depending on the pH of the soil. If you have one of these varieties, you can alter the pH of the soil by making it higher, if you want pink flowers, or lower, if you are looking to have hydrangeas with blue flowers . It is common to resort, for example, to vinegar for hydrangeas, adding it to irrigation in order to acidify the soil. Still, always be careful when altering the pH of the substrate for hydrangeas, keep in mind that it is a long process that must be done slowly and gradually.
Try to put compost in spring in the substrate of your plants, it will help them to give flowers with more force. Always choose organic fertilizers and, if possible, those that are specific for hydrangeas. However, do not abuse its use as it can change the pH of the soil.
