Considering the Soil

About soil condition, hydrangeas like a well-drained, moisture-retentive soil with a pH of 5.5 to 6.5. They will not tolerate waterlogged soils. For planting, prepare a planting hole twice as wide and to the same depth as the root-ball. If the soil is very dry, soak the root-ball in water for about an hour before planting. Position the plant so that the top of the root-ball is level with the soil surface. Backfill with soil, firming gently as you go. Water well to settle the soil around the roots.

About light

Not too different with other plants, hydrangeas need sunlight to grow. However, too much sun can damage the plant and cause the flowers to fade. The best location for a hydrangea is in an area that gets partial sun, such as a spot that gets morning sun and afternoon shade.

The Temperature

The temperature condition that is required for different types of hydrangeas to flourish may surprise you. For some hydrangeas, cool temperatures are essential for vibrant blooms, while others require warm temperatures. Here is a breakdown of the different temperature needs for some of the most popular types of hydrangeas: -Mophead hydrangeas: These hydrangeas require cool temperatures during their blooming period in order to produce vibrant flowers. If the temperature during their blooming period is too warm, the flowers will be less vibrant and may even fade to brown. -Panicle hydrangeas: These hydrangeas require warm temperatures during their blooming period in order to produce beautiful flowers. If the temperature during their blooming period is too cool, the flowers will be less vibrant and may even fade to brown. - Oakleaf hydrangeas: These hydrangeas can tolerate a wide range of temperatures, both cool and warm. However, they prefer cool temperatures during their blooming period in order to produce the most vibrant flowers. As you can see, different types of hydrangeas have different temperature requirements in order to thrive. Make sure to research the specific needs of the type of hydrangea you have before planting to ensure that it will have the ideal conditions to flourish.

Humidity Aspect

Ideal humidity condition for this plant is 50% If the humidity is too low, the flowers will wilt and the leaves will become dry and brown. If the humidity is too high, the leaves will turn yellow and drop off.

The Fertilizer

About fertilizer, this family of plant is not too picky. Something like a 10-10-10 fertilizer will work just fine. Apply it around the base of the plant once a month during the growing season.

Plant Pruning

Pruning is an important aspect of caring for hydrangeas. The type of pruning you do will depend on the type of hydrangea you have. For bigleaf and oakleaf hydrangeas, you'll want to do a light pruning in late winter or early spring. For paniculata and arborescens hydrangeas, you'll want to do a more heavy pruning in late winter or early spring.

About Propagating

Propagation is often done through rooting stem cuttings taken from the desired plant. This is a simple process that can be done at home with some basic supplies. Fill a planting container with a moistened peat moss and perlite mixture. Cut a 6-8 inch stem from the plant, making sure to choose a healthy stem that has not flowered yet. Strip the leaves from the bottom half of the stem. Dip the bottom of the stem in rooting hormone and then plant it in the moistened mixture. Place the container in a warm spot out of direct sunlight and keep the mixture moist. Roots should form within 4-6 weeks. Once the roots are established, the plant can be transplanted to a larger pot or into the ground.

Growth Speed

Usually, the plant growth rate are very slow. The big leaf hydrangea can take up to five years to reach its full potential size. The panicle hydrangea is a little faster, typically reaching its full size in three years.

The Problems
