When is the best time to repot Christmas cactus?

Generally, Christmas cactus can be repotted after 2 to 3 years of care . It is best to repot Christmas cactus one month after flowering to allow the branches to accumulate nutrients before repotting.

In the articles about repotting Christmas cactus that we see on the Internet, it is written that spring and autumn are the best time to repot Christmas cactus. This statement is rather general.

Although spring and autumn are both suitable for repotting Christmas cactus, it is imperative to follow the principle of "season as auxiliary and temperature as dominant". The best conditions for repotting Christmas cactus are when the temperature is maintained at 18 to 28 degrees Celsius.

The best time to repot Christmas cactus is in spring, one month after Christmas cactus blooms, when the temperature is suitable for repotting . After blooming, Christmas cactus consumes a lot of nutrients, and the plant is in a fragile period. There will be many uncertain factors when adapting to the pot, which may lead to death.

(1) Preparation before repotting:

1. After the flowers of Christmas cactus have faded, you can trim the remaining flowers and apply urea with high nitrogen content to strengthen the branches and leaves of the plant. Apply organic fertilizer again half a month later to supplement phosphorus and potassium to promote root growth.

2. After applying organic fertilizer for about 10 to 15 days, when the temperature reaches above 18 degrees Celsius, you can consider repotting. Before repotting, you should reduce the watering time appropriately. It is about 5 days longer than the daily watering time.

(2) Repotting operation:

1. Prepare suitable planting materials. It is recommended to use a mixture of 1/3 garden soil + humus soil + freshwater river sand, and add about 1/5 perlite, which can be used as new planting materials.

2. When removing the Christmas cactus from the pot, I suggest you turn the pot upside down and rinse off the old soil with water. Try not to damage the small white roots. After removing the pot, shorten the overlong roots and comb the dense branches.

3. Before repotting, you can comb the branches of Christmas cactus properly. Comb and prune the dense and tangled branches, and appropriately shorten the long branches.

(3) Maintenance after repotting:

1. After repotting, there is no need to water the plants to help them take root. Just spray the trunk and leaves 2 to 3 times a day.

Water the roots after the third day, and make sure to water thoroughly. For later maintenance, water the plants according to the method of "do not water if the soil is not dry, and water thoroughly if it is". Spray the pot once in the morning and evening every day.

2. Keep the newly repotted Christmas cactus in a well-ventilated and brightly lit location. After a week, gradually increase the light exposure to 3 hours of weak light per day. After another 10 days, you can move the pot to a location with sufficient light.
