What Is Hydrangea?
Hydrangeas are flowering plants with long stems and small leaves. They grow from the ground up to form a large bush or vine. Their flowers have white petals and red stamens (the seeds). The flower spikes are used in perfumes, soaps, cosmetics, medicines and other products. The plant’s name comes from the Latin word hydria meaning “water”.
The plant grows naturally in warm climates, but it is not native to North America. It was introduced into the United States through European settlers. The first documented introduction of Hydrangea occurred in 1790 when it was brought to New Jersey by William Henry Brinton, a British naturalist and botanist. Since then, Hydrangeas have been grown commercially throughout the world.
How Can I Grow Hydrangeas?
Growing Hydrangeas requires very little care. You do need to provide them with good drainage, which means keeping your soil evenly moist all the time. If you don’t give them enough moisture they will wilt and die. Soil pH needs to be between 6 and 7.5 in order for Hydrangeas to thrive successfully. If your soil is not within this range, you can add lime to lower the pH or sulfur to raise it.
When planting your cuttings, make sure that the soil temperature is between 50 and 80 degrees Fahrenheit (10 and 27 degrees Celsius). If it is colder than this, you need to wait until the temperature is right. If it is too hot, the cuttings will wilt and die. After planting, keep the soil moist but not soggy and ensure that the area gets a lot of sunlight.
You can propagate by growing new plants from the seeds, growing Hydrangeas from woody stems or growing them from leaf cuttings. The most common is to grow them from leaf cuttings because they are easy to transplant when small.
Propagating by growing new plants from seeds takes a lot of time. Growing them from woody stems is more difficult because the stems need to be obtained while the plant is still young. The easiest way is to grow them from leaf cuttings.
As a rule, keep the cuttings in a jar filled with water until you are ready to plant them.
How Do I Take Cuttings?
There are a number of ways to take cuttings, but you need to learn which ones work best for your situation. Take cuttings in spring or summer and avoid autumn because the plant needs all of its strength to prepare for the winter.
You can take cuttings from young plants or mature plants. It is easier to take them from young plants because mature ones have roots that are embedded in the ground and it is more difficult to separate them from the parent plant. Choose a plant that is already growing well.
The best time to take cuttings is during the springtime. You can also take cuttings in summer. Avoid taking them in autumn because the plant needs all of its strength to prepare for winter. For best results, take several cuttings from several different plants. This increases your chances of success.
How Do I Go About Taking Cuttings?
Various types of cuttings are possible. You can take:
Steal cuttings- These are pieces of stem that you remove from the plant. They will have one node closest to the mother plant.
Softwood cuttings- In this case, the stems are specifically from new growth that is still soft and juicy.
Hardwood cuttings- This involves using stems that are starting to dry out.
Leaf Cuttings- These involve removing a leaf from the plant and planting it in soil. It will produce roots and you can then plant it in the ground or another pot.
Each type of cutting requires different treatment before you can put them into soil. The right treatment will help to ensure success. Let’s take a closer look at each one.
