How to graft cactus onto crab claw orchid

The cactus grafted with crab claw orchid not only makes it look beautiful and resembles a rockery green tree, but also can see the beauty of the cactus orchid in summer, and the beauty of the fiery crab claw orchid can be seen in the cold winter, making our room more comfortable and healthy. let's take a look at how cactus grafts crab claw orchid!

Rootstock and scion treatment

1. Rootstock selection: the cactus used for grafting must be thick and strong, and its cultivation method is imitated by the general cactus cultivation method, which is generally grafted when the pot diameter is 30 cm and the cactus grows to 30 cm high.

2. Scion selection: the crab claw orchid used in scion requires that the robust mother plant of crab claw orchid should be selected, from which the tender top branch with nodes should be selected as scion with a length of 3-4 cm.

3. Scion treatment: cut the lower sides of the scion into a wedge with an alcohol sterilized blade, with a cutting length of 0.8 cm to 1.2 cm. Grafting time is generally chosen in May or October, the weather is too cold and too hot is not conducive to its survival.

Grafting time and method

1. Selection time: the grafting of crab claw orchid is the best in the growing period, which can be grafted from the end of March to October, but the best period is from April to July, during which the survival rate is high and the growth is fast.

2. Insertion method: for the leaf cactus rootstock with a diameter less than 3.0 mm, choose one side to cut a knife from top to bottom to expose the wood. In the middle part of the vascular bundle at the base of the scion, a sharp knife is used to cut the incision from the bottom up along the leaf surface, and the width of the incision is the same as that cut by the leaf cactus. Insert the scion into the cut of the rootstock so that it meets closely, and then fix it with transparent tape or plastic sheeting.

3. Split method: rootstocks with a diameter greater than 3.0 mm shall be cut directly from top to bottom at the cut, with a depth of 1.5 cm. Cut off the positive and negative epidermis at the base of the scion to expose the vascular bundle and form a wedge. Insert the scion into the incision of the rootstock and align the vascular bundle of the cutting surface with the incision of the rootstock, and then bind and fix it.

4. Build a bracket: after the grafted crab claw orchid survives, generally after a year or so of growth, the crab claw orchid will surround the cactus. At this time, it is necessary to make a bracket to make the grafted crab claw orchid hang on the cactus like a fountain.

Maintenance and management after grafting

1. Watering: when watering, we should grasp the principle of "dry and thoroughly irrigated, no dry and no watering". The water temperature should be close to the soil temperature as far as possible, watering in the morning or evening in summer and 10:00 to 11:00 in winter. And water directly to the basin soil, otherwise it will affect the beauty of the thorn.

2. Fertilization: fertilization should grasp the principle of "timely, appropriate amount, depending on the object". Fertilization should be carried out in spring and autumn, once every 15 days, and should be carried out in the early morning or evening on a sunny day. The method of fertilization is to dissolve the fertilizer to be applied in water and pour it into the basin in the morning. The concentration is about 0.2%.

3. Illumination: cacti prefer plenty of sunshine, especially in winter, and prefer semi-overcast conditions in summer, and keep them indoors in summer high temperature season. Put in a sunny room in winter, crab claw orchids can produce fiery red flowers during the Spring Festival.

4. Temperature: the optimum temperature of cactus is 20-35 ℃. It is suitable to maintain 10-18 ℃ or higher in winter. When the summer temperature is too high, it is necessary to shade the sun and sprinkle more water to the ground to lower the temperature.
