  • To pot up the Hydrangea, use a large, well-ventilated container and good potting soil. Put the plant in a spot where it will get a lot of sunlight straight on its leaves. Hydrangeas can grow in the partial shade outside, but indoor plants require full sunlight (but not intense, direct sunlight).
  • Be careful not to over-water your potted hydrangea houseplant while it’s blooming. Reduce watering after flowering, but don’t let the potting mix entirely dry up. Plants in pots should be hydrated with distilled or rainwater rather than tap water, as tap water typically contains chlorine and other contaminants. If the air in your home is dry, you can use a humidifier or place the plant in a humidity tray.
  • The leaves will turn brown and crispy around the edges in a warm room. Avoid draughts and heat sources. While the plant is blossoming, use diluted water-soluble fertilizer weekly. After that, go monthly. Dormancy is recommended for hydrangea houseplants in the fall and winter. Place the plant in a 45-degree Fahrenheit room without heating (7 C.). To prevent wilting, keep potting mix dry and water sparingly.

Blooming Hydrangeas need 50-60°F (10 and 16 degrees Celsius). Warm temperatures make leaves brown and crunchy. Remove draughts and heat from the plant.

Utilize a diluted, water-soluble fertilizer every week while the plant is in blossom. Reduce the frequency to once per month after that. In the fall and winter, hydrangea houseplants should enter dormancy.

Place the plant in an unheated 45-degree Fahrenheit chamber (7 C.). The potting soil should be kept dry and irrigated sparingly to prevent plants from withering.


The plant should be placed in the room’s middle. Nighttime is OK if that’s your preference. In contrast, hydrangeas demand more sunlight during the day.

The plant should be positioned where it will receive at least some direct sunshine. If you prefer, you can remove the flowers once they’ve faded. However, it isn’t required.

Maintain an evenly wet but not soggy soil during the plant’s development and blooming phases. Because the roots in a pot are usually tightly packed, it is essential to water them frequently.

To avoid alkalinizing the soil, only use water that has been treated to remove lime. When the Hydrangea is dormant in the winter, water it sparingly.


A hydrangeaApply diluted balanced fertilizer every two weeks during spring and summer. Or, apply a slow-release fertilizer twice a year, in the spring and the summer.

Too much fertilizer can burn its leaves, so be careful. To ensure that the soil is nutrient-dense, fertilization is a must.

Flowering plants need a fertilizer that dissolves quickly and is half-strength during this time. However, feeding them only monthly is sufficient in the fall and winter.

When a plant appears to be sick, do not use fertilizer because the plant will only be put under more stress.

In the spring or early summer, take 4-inch (10 cm) stem tip cuttings and root them in moist potting soil. Don’t forget to prune the plant once it has begun to grow.

This is critical for controlling the plant’s size, especially since it will be kept indoors. Pruning diseased or drooping blooms prevents the illness from spreading to the plant’s healthy sections as a potential vector for infections that might harm the plant, ensure that the pruning shears are clean.

  • Potted Hydrangeas are prone to wilting. Keeping them indoors in April and May is the most challenging part. As soon as possible, move your Hydrangea out of the greenhouse and into a slightly bigger pot. A drainage hole and a pot with at least an inch of different diameters are mandatory. Fill the voids with more potting soil, but do not pack it too firmly. Squeezing the air out of the potting soil while plugging it into a pot is crucial because water flows and roots grow in these tiny air spaces.
  • Keep your Hydrangea in a bright but not direct sunlight location after repotting. A window facing east is ideal. Plants will also flourish if placed near a window facing south or west, but not directly in.
  • When the soil feels dry, water your Hydrangea. Do not allow it to become so dry that it wilts. The roots may rot if the pot is kept in a saucer of water for more than an hour.

It’s time to move your Hydrangea outside into partial shade at the end of May, then bring it in at night. Make sure your Hydrangea gets morning sun and afternoon shade after a week.
