What do Kalanchoe Seeds Need to Grow? [Easy Guide]

Though Kalanchoe plants are not invasive, they multiply by seeds. If you are into this propagation, ensure that the time is spring with refreshing temperatures. 

In general, Kalanchoe seeds are tiny, dust-like particles, barely about 1 mm long, with a rusty brown appearance. To germinate, these seeds require a moist environment with 75% humidity, a temperature of 60-70 degrees Fahrenheit, and well-draining, warm, moist soil.

Propagation from the seeds is useful, especially if you want a variety of flowers with different colors, while propagation by cutting does not provide that advantage.

How do You Harvest Kalanchoe Seeds?

Kalanchoe represents a slow-growing plant that can take 2-5 years to reach mature size. 

It blooms almost throughout the year but produces flowers in late winter to late spring when grown in a pot.

After the first bloom, Kalanchoe flowers can last up to eight weeks.

You can take two Kalanchoe plants of different colors and crossbreed and transfer pollen from the flowers of one plant to another.

After the flowers wilt, they develop seed pods. Make sure the seed pods are brown, as fleshy green pods indicate that the seeds are not ready for harvesting.

Steps to Harvest the Seeds from the Kalanchoe Plant

Collect the required materials, including Scissors, Forceps, Paper Towel, Mask and Gloves to proceed.

  • Take a plant pot with dried flowers, take one flower and pull the petals apart.
  • If the seed pod inside is still green, let it dry for a week or more, as it is impossible to extract seeds from a fresh seed pod.
  • If the seed pod has dried enough, cut the whole branch off. This way, the plant can grow new branches and flowers.

Kalanchoe may take eight weeks to produce seeds.
  • Take another dried flower and pull the entire petal off gently. This way, you can now see a dried seed pod.
  • After pressing gently on the seed pod with your thumb, you can get dust-like seeds.
  • Otherwise, take a tea strainer and put all the dried flowers in the sieve. Press the flowers against the strainer, and the seeds easily fall out.
  • Place the seeds in a paper towel with the help of forceps for later use.

How to Grow Kalanchoe from Seeds?

It is better to sow the Kalanchoe seeds during the summer as they will get sunlight for a long time. The seeds have a minimal to no chance of germinating if you sow them during dark, cold months.

Step 1: Preparation of the Seeds and Planting Medium

The first step is to prepare the seeds and growth substrate for planting.

  • Although the seeds do not require much preparation, removing the husks, flowers, and seed pod parts is always a good idea before sowing.
  • For efficient growth, put the seeds in a Ziploc bag under the sun for a whole day.
  • Take a well-draining pot or a seed tray with three parts potting soil, two parts coarse sand (surface or poultry grit), and 1 part perlite (or pumice). Or, you can buy a succulent soil mix.
  • Lightly water the soil to make it moist enough for planting seeds.

If you are still confused, here is the visual guide.

Step 2: Sowing the Seeds

  • Now, it’s time to plant the seeds. Take some seeds and spread them on the surface, but you need not bury or press them hard.
  • Cover the pot or tray with a plastic bag or glass as soon as seedlings appear to ensure no moisture loss. The bag will maintain humidity.
  • Water the pot or tray if the soil is dry and leave it if the soil feels moist.
  • Keep the pot or seed tray in a place under bright indirect light.

Step 3: Care for Kalanchoe Seeds During Germination

Kalanchoe seeds do not require much care during propagation like any other succulents. However, you need to mimic the following condition to ensure the surviving habits. 

  • Kalanchoes plants need the high light intensity of a lighting source (3500 to 4500-foot candles) to grow compact and control height.
  • If you live in colder regions or are trying to grow the plant in winter, you can opt for artificial heating.
Kalanchoe may need more than a week to develop seedlings.
  • Make sure to provide enough moisture to the soil and let it have a pH of 6.0 to 6.5. 
  • Protect the growing seeds from birds and other pests. Cover the pot with plastic wrap for protection, sealing the moisture.
  • Wait for germination, which may take about ten days in light at 70º F. As a result, seeds sown in mid-March can develop 4-inch flowering plants by December.
  • As Kalanchoe has a brief juvenility period (up to eight pairs of leaves), it is wise to provide seedlings with night-breaking lighting until the end of March.
The Kalanchoe seedlings need to transplant into 2-inch pots seven weeks from sowing.
