Would you like to multiply hydrangeas from your cutting? Nothing could be simpler, with a pinch of green thumb and a great desire to see this creation with a few simple steps. Let’s find out together all the tips of the expert nurseryman to do it in the best possible way.
How do hydrangeas multiply from cuttings?
The multiplication of hydrangeas through cuttings is an effective method of obtaining new plants from existing specimens. This technique, if followed correctly, allows you to successfully propagate this fascinating ornamental plant.
First of all, it is important to choose the right time to carry out the multiplication using cuttings. The ideal season is spring or autumn, when the plant is in an active growth phase. Select a healthy and robust mother plant, preferably with young and vigorous side branches.
Once you have identified the suitable mother plant, proceed to take the cuttings. Cut a side twig about 10-15 centimeters long, preferably with two or three knots. Use a sharp knife or a clean and disinfected pair of garden shears to prevent the spread of disease.
After taking the cuttings, it is important to prepare them correctly to promote rooting. Remove the basal leaves, leaving only those present at the upper end. If the leaves are very large, you can reduce their size slightly to reduce moisture loss.
At this point, soak the base of the cuttings in a powdered rooting hormone, following the manufacturer’s instructions. This will promote root development and speed up the rooting process.
Next, place the cuttings in a light, well-drained substrate, such as a peat moss and perlite mixture. Place them in a plastic container or box, keeping a distance of at least 5 centimeters between the cuttings. Cover the container with a clear plastic bag or use a greenhouse to create a humid and controlled environment.
Place cuttings in a bright area, but avoid direct exposure to bright sunlight. Keep the soil constantly moist, but do not overwater to avoid root rot.
After a few weeks, the roots will begin to develop and the cuttings will root. This can take anywhere from two to four weeks, depending on environmental conditions and the variety of hydrangea.
What to do after the cutting has rooted well?
Once the hydrangea cuttings have rooted properly, they can be transplanted into individual pots or directly into open soil. Choose a location with good sunlight exposure and prepare the soil with humus or compost to ensure healthy growth of new plants.
During the first few months, young plants will require special care and attention. Keep the soil moist, but not overly wet, and protect plants from high winds or extreme temperatures.
