Now is the best time to start your first succulent container garden. For any succulent gardener, perlite and pumice can be useful, regardless of whether you are making your own soil or adding to the one that you purchased from the local gardening centre. It absorbs water, which makes it ideal for keeping your terrarium moist. If you're short on space, bonsai is also a great way of keeping your succulents small and more manageable. The soil should only contain a small amount. This shouldn't cause any problems. Most cases it won't take more that a month for the plants heal and seal themselves.
