Step 1: Sowing String of Dolphins from Seeds

Now, first of all, planting your String of Dolphins seeds will not be an outdoor project. The seeds are so small that the wind can easily blow them away, so place everything on an indoor table. Placing paper towels under your “sowing station” can help if you manage to lose a few seeds along the way.

Fill the compartments of your sowing tray with vermiculite or whatever medium you choose. Then go ahead and moisten the soil, which is easy to do if you are using a propagation tray, as they tend to have a removable sub-layer that you can flood. Once the soil has been sufficiently moistened, you can sprinkle the seeds in there.

This can be done with your fingers, but some prefer to use something like a toothpick or paintbrush, as the seeds are very difficult to work with. However you do it, place some seeds in each container, but don’t overdo it, as this will make repotting later very challenging.

Step 2: Placement

That’s it for the sowing process: now you just need to make sure the moisture stays in and give the seeds time to grow. If you used a regular pot, put it in a clear zip-lock bag. In the case of a propagation tray or plastic container, you can simply put the lid on and make sure it is tightly closed. Then place it under the grow light or on a window sill that gets plenty of light but not the direct sun (north or west in the Northern Hemisphere).

Step 3: Germination String of Dolphins

Most seeds germinate soon, you may see growth within a month or so if they were fresh and circumstances are favorable. Once the sprouts appear, you can remove the cover to give them fresh air, as too much moisture can cause rotting or mold problems.

They will need to be kept constantly moist at first until they establish their root systems, but as the weeks go by you can slowly reduce the frequency of watering.
