If your Christmas Cactus is still dormant, put it on the windowsill of the room with little light. Give it water more than once a month. Give it through once. Leave it alone if the leaves are wilting. It's ok if the roots don't rot. the key is to keep the ventilation.
When the temperature cools down, the leaves of crabmail become hard, the wrinkles are reduced, and the color is brighter than before, which means that it will wake up soon, so it is necessary to increase the frequency of watering a little. As it grows better, it is necessary to slowly increase the amount of watering.
When the temperature drops below 30 ℃ in September, the growth will be fully recovered, and then the top dressing will be started. The nitrogen, phosphorus and potassium compound fertilizer will be used once a half month. If the crab is grafted, the fertilizer can be used once every 7-10 days. If sufficient nutrients are accumulated, new shoots will emerge.
At the beginning of October, when the new buds grow to more than 2 nodes, take off the thin and tiny tender leaves at the top, which is equivalent to a "small mechanism". Once opened, the top of the old leaves will start to huff and puff, bask in the sun more often, spray more 2 fertilizer once every 10 days, and the buds will be more!
After the flower bud comes out, water less, keep the surface half dry, don't move the flower pot often, don't spray water on the flower bud, or it will fall, and bloom after a month's rest.
If the leaves of Christmas Cactus are big and fat, the color is dark green, that is, there is no flower bud all the time, it may be lack of phosphorus and potassium fertilizer, and it can be directly applied with potassium dihydrogen phosphate or huaduo2 liquid fertilizer.
If the new leaves turn red at low temperature, they will sprout soon. Don't worry, keep them by the window, freeze them at night and sun them in the daytime, and they will bloom in a month.
The other is to control the light. Crabmail is a short sunshine plant. If the light is too strong and the time is too long, it will affect the flowering. You can put a small black plastic bag on it. It will see light for 8 hours every day and block the light for 16 hours, and the flower bud will come out soon.
If the rotten root is not serious, dig it out and let it dry for a few days before replanting.
If the rotten root is very serious, remove the rotten part at the bottom, dry the wound, and plant the root in the water and then replant it in the soil.
If your Christmas Cactus doesn't reach the situation of bursting the pot, it's suggested not to change the pot in autumn. After all, the pregnant bud is about to bloom. Wait for the next spring, and then change it after the flower is gone! If the pot is too long to bloom, it's better to change it around the Mid Autumn Festival. The root crab can take out the pot if it pokes its finger up the drain hole.
To change a basin slightly larger than the original one, use 2 parts of peat soil + 1 part of garden soil + 1 part of coal ball ash or coarse sand, and lay a layer of particles on the bottom of the basin.
After a week of basin changing, new buds began to swish and grow, and continued to make up fertilizer. More than a month later, flower buds appeared.
