Adenium Seeds Germination

Adenium are very easy to grow, as long as you give them what they need to thrive.

They usually germinate within 7 to 14 days and occasionally some will germinate within a day or two.

If growing Arabicum, Thai Socotranum, Somalense or especially multi-florum we would recommend increasing the heat slightly, germinate in seed trays instead of pots and do not assume they can just be planted in the same tray as your obesum which germinate much more readily.

For Adenium to germinate you need a few key ingredients.

1. Fresh Seeds

2. Lots of Light (Sunlight or Grow lights)

3. Heat (25 to 35 degrees Celsius)

4. Water (Humidity)

5. Good Draining potting mix

Step 1 Soak seeds in warm water for a minimum of 2 to 4 hours to rehydrate the seed.

Our preferred method is to soak them overnight and plant them the following morning.

Fill a seed tray with a quick draining potting mix, something like the following combination works out great value with high germination rates: 50/50 mixture of Cactus Compost & Perlite although we prefer to use coco coir.

Make a 3- to 4-inch layer of the potting mixture in the seed tray.

Step 2 After the seeds have soaked for the allotted time carefully place the Adenium seeds on the potting mixture surface, spacing them about 1 to 2 inches apart.

Barely cover the seeds with the potting mixture.

Step 3 Water your Adenium seeds to thoroughly moisten the potting mixture in the seed tray. Water the seeds once every week, only when the potting mixture is almost dry you can choose to mist them with a spray bottle if you prefer.

DO NOT ALLOW TO DRY OUT AND DO NOT LET THE MIXTURE BECOME WATER LOGGED.

Step 4 Maintain air temperatures around the Adenium seeds of around 85 degrees Fahrenheit.

It would be ideal if you had a propagator and a good light source.

Move the seed tray into full sunlight when the seeds germinate and begin to sprout.

Step 5 Transplant the seedlings when they have at least three sets of "true" leaves, which are the larger leaves that emerge after the smaller seedling leaves. You can usually transplant the seedlings about one month after planting the seeds.
