This helps the cut edge to heal slightly and avoids stem rot which occurs when there is excess moisture in the plant. The cutting can be left to dry for up to 4 days. A mixture of moist peat and sand soil will provide enough nutrients for your growing plant. It will also allow proper soil drainage which is very important for cactus growth. You can also layer pumice on the bottom of your pot for additional drainage. Make sure the cutting is about an inch deep to allow it to absorb enough moisture and nutrients.If needed, you can place multiple cuttings per pot at this stage of the process. While it can easily adapt to low light conditions, your Christmas cactus will thrive in bright, indirect light. Avoid direct sunlight as this can easily burn the cactus leaves. Water your cuttings sparingly to prevent rot. After 2-3 weeks, your cutting will show growth at its tips. These are usually red in colour and a sign you can now transplant it into a bigger pot Fill this with a loose mixture of potting soil. Alternatively, you can use the same soil as the mother plant.  Don’t worry if your plant wilts at the beginning. This is normal and will subside once the plant gets used to its new home. At this point, your plant can be exposed to more indirect sunlight. Once your cutting has developed roots and new growth, it can retain water just as well as an adult plant. Ensure that the soil remains moist and care for your plant in the same way you would a mature cactus. Test the soil to see if it needs watering. Once the top layer of the soil feels dry to the touch, it is time to water again. Christmas cactus plants like to live in tight pots so don’t need to be repotted very often. Repotting should be done after blooming in late winter or early spring.

How would you rephrase that briefly using Vietnamese?
Chờ 2 ngày cho các cành cây khô. Đổ đất trồng cây có độ thoát nước tốt vào các chậu nhỏ. Cắm từng cành xương rồng vào đất. Đặt chậu cây ở khu vực mát có ánh nắng gián tiếp. Trồng các cành xương rồng vào chậu lớn hơn. Tưới nước thường xuyên cho cây. Thay chậu cho cây sau mỗi 3-4 năm.
