Are you very jealous after reading it? Don't worry, follow Huahua to learn the maintenance experience of Dafeng, you can also raise such a scale in 2 years!
In autumn, Christmas Cactus will produce a lot of new leaves, which consume too much nutrients, and will affect flowering. In order to promote flowering, after the 11th, you can gently break off the top, thin and tender leaves, and there will be flower buds in a period of time, and the crab that pinched the top buds will blossom more and more orderly.
Note: do not break the top bud of the newly grafted seedlings, do not rush to let them bloom. First, grow leaves, the more buds, the more lush leaves, and the faster forming. Keep the seedlings for one or two years and then consider pruning.
If the Christmas Cactus has long leaves and no flower buds, and the leaves are green and fat, it means that it is lack of phosphorus and potassium fertilizer. Spray huaduoduo 2 or potassium dihydrogen phosphate solution to the leaves every 10 days, and the flower buds will come out soon; stop fertilization after the flower buds are colored.
Crab claw orchid is a short sunshine plant. In the south, if the light is too long, it will affect the flowering. You can put a black plastic bag on it. You can see the light for 8 hours every day and block the light for 16 hours. You can gestate the flower bud for a period of time. After the bud appears, remove the plastic bag and put it in the bright astigmatism of the living room.
1. Grafting time
The most suitable grafting temperature is 15-25 ℃, so the survival rate is the highest from mid March to late May in spring or mid September to the end of October in autumn.
2. Stock selection
The first choice of Southern flower friends is Ye Xian, which is resistant to floods and droughts, grows fast and has strong resistance, but ye Xian is afraid of cold, so it is not suitable for the north. The northern flower friends use cacti better, of course, cacti are common in the north and the south.
1. Ye Xian is used as the rootstock, and the sterilized blade is used to cut into the xylem quickly to form a wedge-shaped incision.
2. Crab claw orchid is used as scion, and the leaves of the 2nd and 3rd sections from the top to the bottom are the best. If you choose the ones with thick oil and green fertilizer and no diseases and insect pests, you can pick 3-5 sections.
3. Use a blade to cut a wedge-shaped opening at the lower part of the blade, the size of which is similar to that of the cutting of the rootstock. Both sides should be cut quickly, and do not cut back and forth.
4. Insert the treated leaves into the cut of rootstock, and then fix the grafting part with plastic clip, and the scion cannot slide.
5. After grafting, put the flowerpot in a cool and ventilated place, do not water it for a week, and do not touch the interface part with water. If the leaf does not wilt after half a month, it will survive; about two months, small shoots will appear on the top.
6. For multi-layer grafting, set up a shelf or insert several sticks in the flowerpot to support, and guide the leaves to grow along the shelf.
Note: ye Xian should not be too greedy for grafting. A branch can be grafted at most three times, two to three layers at a time. The distance between each layer is 40cm, and the overall height is about 1m, so that the bottom layer will not be prematurely aged due to lack of light.
1. Cacti often use big yellow thorns. Select strong and fat leaves, cut off the top, and expose the cambium. Use the sterilized blade to make a small incision with a depth of 1cm, the width is similar to that of Christmas Cactus leaves.
2. Select 2-3 healthy leaves, and cut 1 /4 of the bottom with a sterile blade to expose the white xylem. Cut both sides to form a V-shaped socket.
3. Insert the shaved leaves into the cactus incision immediately, try to keep the vascular bundle of crab and the prick point of cactus in a straight line, and then fix them with toothpicks or clamps to prevent the cuttings from moving.
4. After grafting on the top layer, the surface of cactus leaves can also be grafted. Use the sterilized blade to make several cuts from the side, insert the treated leaves of crabmail and fix them with toothpicks, so as to form multi-layer grafting.
5. Set up a shelf or insert a few sticks in the flowerpot to support the multi-layer grafting. Because the cactus is relatively slow in providing nutrients to the top, do not graft too many layers to affect the life span.
6. Keep cool and ventilated. The wound should be dry. After 2 weeks, the leaves did not wilt, indicating the survival of grafting. It should be noted that the air is too dry in autumn, which affects the survival rate. You can put a bag to improve the air humidity.
If you receive direct light for a long time, the leaves will turn red and soft. In fact, Christmas Cactus doesn't need to be exposed to the sun hard, and it can have bright scattered light.
Crab claw orchid is more drought resistant, but it can't be dried for a long time. The leaves on the top will wilt after lack of water. Usually, water it to see the pot soil. When the pot becomes light and the pot soil becomes dry, you can water it.
The leaves of flowering Christmas Cactus are very soft and normal. After all, it needs a lot of energy to bloom. If the roots are weak, the leaves will be in a worse state. After the flowers are spent, it will slowly slow down by applying a little thin compound fertilizer every half month.
If the color of the leaves is dim, and the basin soil is wet for a long time, it is basically rotten root. We should dig out the rotten root, trim the rotten root, and change the soil for transplanting. If not, we should cut the leaves in good condition and cut them again.
It's a must to cut. It's not good if you don't cut it, but the method of cutting is different in different periods.
Some tender leaves just come out in autumn will not bloom in the flowering period, so they should be removed in time to avoid nutrient consumption.
When there are too many bracts in the pregnancy stage, the buds should be properly thinned, one of the largest bracts should be left on each branch, and the rest should be removed, so that although the buds are less open, the flowers will be more beautiful instead of saving nutrients, and the state of the leaves will not be too bad after the flowers are withered;
If the buds are not sparse and too many flowers are opened at one time, too much nutrients will be consumed, which will cause the leaves to wilt and soften, affecting the subsequent growth.
After the flower withers in spring, it should be cut short from the 3-4 stem nodes under the remnant flowers in time, and at the same time, some old stems and too dense stem nodes should be spared to facilitate ventilation.
If the leaves grow too luxuriant, the plant shape is scattered and airtight, heavy cutting shall be carried out after the flower is withered, and all the long stems shall be cut off by 2 /3, the yellow, thin and unhealthy leaves at the bottom shall also be cut off, and the whole branch shall be evacuated and ventilated.
The cut leaves can be propagated by cutting. The cutting methods are as follows:
1. Spread out the cut Christmas Cactus leaves in a place with good ventilation and weak light to dry the wound.
2. Prepare loose and breathable pine needle soil, wet it, air it to half dry and half wet state, and then insert the leaves of Christmas Cactus about 2cm;
3. After cutting, move to a cool and ventilated place. Do not water it, or it will rot before rooting. Spray water on the slice every few days. Rooting will take place in about 20 days.
In order to avoid black rot of cuttings, flower friends can also try to lure roots first, and then pot.
1. Find a sealed plastic container, lay a layer of wet paper towel on the bottom, put the bottom of the blade upward, and cover the cover;
2. After a few days of suffocation, white roots will appear at the bottom of the leaves. This method is particularly easy to use, with high survival rate. When the roots are 2cm long, they will be buried in the soil.
3. Pay attention to the fact that the soil must be loose and permeable, half of coniferous soil and half of rotten leaf soil, and then mixed with fine river sand and bark. After the mixture is even, it will get wet. When it is half dry and half damp, it can be used again. Do not water it immediately after it is used. After the soil is completely dry, it can be used again.
