Petrosedum Forsterianum Growth

The best way to propagate your Petrosedum Forsterianum is through stem cuttings. It is advisable to propagate your succulent during its growing season. Make sure you use clean garden scissors to allow your cuttings to be calloused for a few days before replanting. This helps in preventing any bacteria from being transferred into your new plant.

Also, checking if your chosen mother plant is healthy is crucial, as it signifies if your propagation will be successful. By 2 to 3 weeks, your newly transplanted Petrosedum Forsterianum should have started to grow roots.

Propagation through seeds is also possible. However, this method takes a more extended period. Typically, germination could take place from 2 to 4 weeks. This succulent doesn’t need pruning as it even looks good during winter. Pruning might only be necessary when your succulent gets a bit leggy. Usually, this situation happens when your succulent is not getting enough sunlight. You may prune your succulent to maintain its shape and promote growth or a bushier appearance.

If your Petrosedum Forsterianum starts to grow bigger than its current pot, it is also advisable to repot during the spring season. Unfortunately, your Petrosedum Forsterianum will be attacked by pests due to overwatering. Check for scales, mealybugs, slugs, and even snails. Aside from overwatering, it would help if you also avoided overcrowding and a humid environment for your Petrosedum Forsterianum.
