This succulent has thick swollen stems that help to conserve water and provide stability. Because pumice doesn’t decompose it won’t be necessary to replace it which can help reduce cost. Be careful not to remove the yellow tissues from damaged Madagascar Palms. This can not just stunt the growth of your plants, but can also cause yellowing and loss of leaves. These also propagate easily from the tiny bean shaped leaves. The excessive humidity can cause fungal problems and can even lead to the death of your succulents.
