Christmas Cactus: Watering Needs And Dehydration Risks

Unlike regular cacti, the Christmas cactus is a tropical plant native to the rainforests of Brazil. They grow on tree branches and are used to absorbing water from the humid air. This means they have higher water requirements than most cacti. However, it is important to balance their water intake so that they are not kept too wet. Christmas cacti should be watered around once every two to three weeks, but only when the top third of the soil is dry. They should be watered thoroughly, until water runs out of the bottom of the pot, but the excess water should be discarded after 10-15 minutes so that the plant does not sit in water, which can cause root rot.

Christmas cacti need more water than desert cacti

Unlike their desert-dwelling relatives, Christmas cacti are native to the tropical rainforests of Brazil, where they grow on other plants in the branches of trees. They are used to a soil that retains water and are adapted to a climate with high humidity.

Christmas cacti should be watered when the top third of the soil is dry to the touch. This is usually every two to three weeks, but it depends on factors such as the size of the pot and plant, the temperature, and the amount of sunlight the plant receives. When you do water your Christmas cactus, water it thoroughly, until water runs out of the bottom of the pot. However, do not let the plant sit in water, as this can cause root rot.

Christmas cacti require more water than desert cacti, but it is important to balance this with allowing the plant to dry out between waterings. Overwatering can cause the buds and blossoms to fall off and the roots to rot.

They should be watered every 2-3 weeks

Unlike regular cacti, Christmas cacti require more frequent watering. They should be watered around once every 2-3 weeks. However, the plant and its soil should be the guide. The top third of the soil should be dry before watering again. In an average-sized pot, this would be the top two inches of soil, but in bigger plants, it will be deeper.

Christmas cacti are used to a soil that retains water. In nature, they grow in the branches of trees in the Brazilian rainforest, so they are used to big soaks with dry periods in between. They are also used to taking in moisture from the humid air.

The frequency of watering depends on various factors, including the size of the pot, the temperature, humidity levels, and the season. For example, plants closer to heat sources will dry out faster, while those in cooler rooms may need less frequent watering.

It's important not to overwater Christmas cacti, as this can lead to root rot. They should be thoroughly watered until water runs out of the bottom of the pot, but any excess water should be discarded after 10-15 minutes.

During the growing season (spring and summer), water your Christmas cactus when the top 1-2 inches of soil are dry. In the dormant season (fall and winter), reduce the frequency of watering and let the soil dry out more between waterings.

The key to keeping your Christmas cactus healthy is to place it in the right location and only water when the soil is dry.

They don't tolerate waterlogged soil

Unlike regular cacti, Christmas cacti are not native to dry, hot, desert locations. Instead, they are native to the tropical rainforests of Brazil, where they grow on tree branches. This means that they are used to a soil that is capable of retaining water. They are also used to big soaks with periods in between soakings where they dry out a bit before being watered again.

Christmas cacti don't tolerate waterlogged soil. They should be watered once the potting soil is dry to the touch, allowing excess water to drain freely from the bottom of the container. Do not let the soil become waterlogged by letting the plants sit in standing water. Prolonged exposure to overly wet soil, especially in the winter months, can lead to root rot. If you water your Christmas cactus in the sink, you can return it to its space once it has drained. If you watered it in place, dump out any water in the bottom saucer under the plant. Do not leave the pot sitting in pooled water. If you do, the soil will continue to soak up the excess water, and that will keep the roots too moist. This will cause buds to fall, blossoms to drop, and roots to rot, causing the plant to die.

The key to keeping a healthy plant is making sure it is placed in the right location and only watering when the soil mix is dry. Christmas cacti grow best when they are placed in a location with partial shade, such as an east or west-facing window, with a temperature between 70° and 80°F. Exposure to too much bright sunlight, especially in the summer months, can burn the foliage, and not enough light can slow growth and cause the soil mix to dry too slowly. When in doubt, err on the side of under-watering as opposed to over-watering.

They need a humid environment

Unlike regular cacti, the Christmas cactus is a tropical plant native to the rainforests of Brazil. They grow on tree branches and are used to soaking up high humidity, dappled sunlight, and warm temperatures. Therefore, they need a humid environment to thrive.

Christmas cacti grow well in most potting mixes formulated for succulents, but it is important that the potting soil drains well. You should also choose a pot with a drainage hole in the bottom to keep the soil from getting too wet.

The ideal daytime temperature for a Christmas cactus is 70°F (21°C), with an evening temperature of 60-65°F (15-18°C). They prefer a humid environment, which makes a bright bathroom or kitchen a good spot to keep them. In the summer, they can be placed in a shady spot in the garden or on an unheated porch until temperatures drop below 50°F (10°C). Just be sure to keep them out of direct sunlight.

To ensure your Christmas cactus gets enough humidity, you can increase the humidity around the plant with a humidifier, place the pot on a pebble tray, move it to a room with higher humidity (like a kitchen or bathroom), or mist it regularly.

It's important to note that while Christmas cacti need a humid environment, you should also be cautious of keeping them too wet. Overwatering can lead to root rot, which is caused by fungi that thrive in waterlogged soil. It can quickly spread throughout the root system, causing the roots to become brown and mushy, and unable to absorb nutrients.

They require less water in winter

Unlike their desert-dwelling relatives, Christmas cacti are native to the tropical rainforests of Brazil, where they grow as epiphytes in the shady branches of trees. As such, they require more water than most types of cacti. However, they need a balanced approach that will not keep them too wet, especially during the winter months, as this can lead to root rot.

In general, Christmas cacti only need to be watered every two to three weeks. However, you should let your plant and its soil guide you. Water your Christmas cactus when the top of the soil in the pot is dry. You shouldn't water your plant until the top one-third of the soil is dry. For example, if the plant is in 6 inches of soil, water when the top 2 inches feel dry. You can also check by inserting your finger into the soil about an inch or two deep. If it feels completely dry at that depth, it’s time to water.

During the winter, when indoor heating is running, cacti may need less frequent watering. They typically go through periods of dormancy during the winter months, when they require less water. During dormancy, they can go longer without water than during their active growing season, which is usually spring and summer.

It's important to note that the watering needs of a Christmas cactus can also depend on various factors such as the size of the pot, the temperature and humidity levels in your home, and the location of the plant in your home. Plants closer to heat sources will dry out faster, while those kept in cooler rooms or further away from heating units may need to be watered less frequently.

To summarise, while Christmas cacti require more water than desert cacti, they still need a balanced approach to watering, especially during the winter, to prevent overwatering and ensure their long-term health.
