How to Grow String of Dolphins Plant

String of Dolphins Plant Propagation with Seeds

Fill a pot with black peat mixed with a picex in equal parts, and then add water to the substrate. Place the String of Dolphins seeds on the surface of the substrate and then cover the seeds with a thin layer of pomice or river sand. Finally, place the pot outside, in semi-shade. Water the seeds, but this time with a sprayer. If all goes well, String of Dolphins plants will germinate in 2-3 weeks.

String of Dolphins Plant Propagation with Stem Cuttings

Make sure your stem cuttings contain at least 2 to 3 nodes along their length. These nodes are extremely important because they are the points from which propagation will occur. Nodes allow new stems, leaves, and roots to grow out from them. Damaged nodes will reduce the chance of successful propagation. So, be sure you're using a stem cutting with healthy nodes on it. Having multiple nodes on one stem also improves the chances of successful string of dolphins plant growth and propagation.
  • Propagating Dolphin Plants Stem Cuttings In Soil

Stick the stem in a well-draining potting mix and give it plenty of water. Don’t worry about overwatering String of Dolphins Plant during propagation. Some gardener friends of mine have suggested using cold water to start the growing process of the roots. When the topsoil has dried out, give the Succulents a moderate amount of freshwater. Keep doing this through the next 2 to 3 weeks after propagation. The soil must be fully soaked from the bottom to aid growth.
  • Propagating Dolphin Plants Stem Cuttings In Water

If you’re growing your String of Dolphins Plant in water, use clean water that has a pH of around 7.0. Tap water should be fine, but it cannot deviate by a pH of 0.5; any more than that and your stem cuttings or leaf cuttings will have difficulties rooting.

Repotting String of Dolphins Plant

Repot every three years in the spring, using a 'Cactus & Succulent' labelled potting mix and the next sized pot with adequate drainage. String of Dolphins plants are far better potbound for several years due to the heightened risk of root rot and repotting-issues (like transplant shock), so only repot if you feel it's wholly necessary - restricted root growth will also increase the chance of blooms, too.
Hydrate the String of Dolphins plant 24hrs before tinkering with the roots to prevent the risk of transplant shock. For those situated in a darker location, introduce an extra amount of perlite and grit into the deeper portion of the pot to downplay over-watering risks.
