Kalanchoe is a houseplant that is common in Madagascar and tropical areas of Africa. Kalanchoe looks attractive and has a lot of flowers, which make it popular as a decoration. It's great for putting in small pots and hanging around the front porch.

People also love to place it near the window, on a tabletop, or even among the bushes in the yard.

The term overwintering pertains to prolonging something and allowing it to survive over an entire winter season.

Overwintering a Kalanchoe means you're putting it in a safer place away from too much moisture or cold temperatures. This will help Kalanchoe endure the winter season until it's over.

You can follow the steps below to overwinter your kalanchoe.

1. Relocate the kalanchoe

A Kalanchoe prefers direct and bright light.You can consider relocating it to a better spot, like a window. It's important for kalanchoe to gain enough energy. 

Kalanchoe can withstand a temperature as low as 45 degrees Fahrenheit. However, it's ideal to keep the temperature between 65 and 85 degrees Fahrenheit.

Also, consider placing the kalanchoe away from the reach of children and pets. This is to protect the plant, as well as your children, from swallowing tiny parts that can result in a choking hazard.

2. Provide what the kalanchoe needs

Aside from natural light and temperature, you should provide other things your plant needs, like a pot, soil, and water. It's ideal to use peat moss and perlite of about 60 and 40 percent, respectively.

Peat moss is an organically decomposed fibrous material that can be found in cold wetlands. Peat moss is quite acidic, which helps in growing some plants like azalea. Also, peat moss is sterile, which keeps parasites away from the plant.

On the other hand, perlite comes from a volcanic glass that is heated to a high temperature. It's an inorganic material that is efficient in storing moisture for plant roots.

Perlite also allows air to pass through it, which prevents the soil from being compact and hard. Perlite is being mined in some states, like Arizona and California.

By mixing peat moss and perlite, the quality of the soil will be good enough for kalanchoe. Your kalanchoe can have enhanced sterility while keeping the soil soft with sufficient water and oxygen.

You can use a pot that is 4-6 inches wide and not deeper than 6 inches. There should be holes beneath the pot so that it can drain excess water.

The water should then be caught by a tray or smaller saucer. It's easy to overwater kalanchoe. So remember that you can have an interval of watering it for 8–10 days.

3. Avoid cold cir drafts

If you have an AC at home, then put the kalanchoe in a place far from cold drafts. Cold temperatures can block the nutrients and water from passing through the stems. Since cold air drafts can create moisture, they interrupt the growth of a plant.

Winter is quite a disaster for houseplants, as they get less exposure to sunlight. If the temperature falls below 50 degrees Fahrenheit, the plants may suffer damage. You can consider pausing watering indoor plants and keeping the room temperature warm.

Also, try closing the curtains or turning on your furnace. The warm temperature helps relieve indoor plants from excessive moisture, but you don't want to exceed 90 degrees Fahrenheit, as this can be harmful to your plants.

4. Prune the kalanchoe

Pruning means removing some parts of a plant that can interfere with its growth or blooming process. The kalanchoe need to stay healthy by cutting out unhealthy stems and leaves.

You can use shears to easily cut plants. It's not good to use regular scissors, as some stems are too hard for them.

Simply follow the steps below:

  1. Remove the dying stems that have turned dark brown. Ignoring them can harm the whole plant.
  2. Cut the flower stalks to allow the leaves to have more space for growing.
  3. Cut off the dead leaves or those that are torn and discolored.

You may need to wait for kalanchoe to complete the blooming stage, which takes at least a year. When kalanchoe grow again, cut the flower stems and leaves that have exceeded one-third of the plant.

This is to allow reblooming and to keep kalanchoe healthy for the longest time possible.

5. Nourish for regrowth

Kalanchoe can regrow under proper care and nourishment. It usually takes six weeks of winter before you can see flower buds forming. You can place kalanchoe in a dark area, like inside a closet, during winter to allow flowers to regenerate.

It typically takes eight weeks for kalanchoe flowers to bloom. However, there's a way to make kalanchoe bloom faster. Try putting them in a box for 14 hours a day, then letting them out to absorb light for 10 hours.

For at least six weeks without watering, do this trick. As long as you see a flower bud starting to bloom, put it back under the bright light and continue watering regularly.

Do Kalanchoe Need Fertilizer?

Natural compost can also be used as fertilizer. Just be sure to remove some non-biodegradable waste to prevent kalanchoe from dying due to dissolving toxic components.
