Unlock the secrets to thriving succulents with our comprehensive guide on the best soil for succulents.

Best soil for succulents
Succulents have fleshy leaves that store water. This means that they don’t need to be in continuously damp soil in order to draw up moisture like other plants. In fact, heavy or waterlogged soil will make them very unhappy and could lead to root rot, which can kill them.
Good drainage is the secret of success when it comes to succulents. They prefer a free-draining soil that allows excess water to flow out quickly. You can make your own (see below) or buy a specialist succulent mix.
Here are some examples of pre-made, peat-free succulent potting mix:
