Cattleya Propagation Methods
Main content introduction: Let's follow the editor to explore the content about the propagation methods of Cattleya plants!
Cattleya propagation methods include using cutting or grafting techniques.
1. -- Cutting Propagation --
Choose 3-5变态 stems as cuttings in April to May, let them dry for 1-2 days, then insert them into sand or vermiculite, place them in a shaded area, water slightly, and keep the humidity not too high. It takes about 20 days to root. However, Cattleya propagated by this method grows slowly, has poor growth, fewer flowers, and poor shaping. Therefore, grafting is usually preferred to cultivate into an umbrella shape.
2. -- Grafting Propagation --
Grafting can be done in spring or autumn, with spring being the best time. If well maintained, it can bloom in the winter of the same year. The rootstock often chosen is cactus or triangular arrow. First, use a disinfected knife to cut off the top part of the rootstock horizontally, then cut a V-shaped notch from top to bottom on the rootstock. Then, select 2-3 sections of the not too young nor too old Cattleya stem as scions. The flat sides of the scion stems should be peeled with a knife to form a wedge shape. It is best to cut it in one go without repeating the cut.
After the scion is cut, insert it immediately into the V-shaped notch of the rootstock, with a depth of 2-3 centimeters. To prevent the scion from slipping out, a cactus thorn can be used to secure it. During grafting, gently hold the rootstock incision with your hand to tightly clamp the scion and pause for a moment to allow the two parts to adhere and the fluids to interpenetrate. afterward, it is best to wrap it with plastic film and place it in a shaded and rain-free area for maintenance. Generally, keeping the soil moist is sufficient, do not water too much, and water should not enter the joint. It usually takes half a month to survive.
Cattleya propagated by grafting has a more beautiful shape, and the root system of the rootstock is developed with strong vitality, robust plants, and more flowers. It usually blooms in the same year. The above is an introduction to the propagation methods of Cattleya.
