Soil: Succulents and cacti thrive in well draining, porous soils. Gravel or expanded shale can be added to the bottom of the container to help increase drainage. A basic, sandy potting soil mixed with vermiculite makes a great succulent mix!
Also question is, do you need special soil to plant succulents?
Succulents need soil that drains, so regular potting soil—or dirt from your yard—won’t do. Choose cactus soil or mix potting soil with sand, pumice, or perlite. Succulent roots are very fragile so be gentle when repotting.
Then, do succulents like to be crowded?
As a rule, succulent plants do not mind crowding whether the plants are grouped in one container or are alone and fully filled out in the container. Transplanting a plant that has filled its container will generally allow the plant to experience a new spurt of growth.
Where should I plant succulents outside?
Succulent Outdoor Plants
Sedum and sempervivum are easy to grow and adaptable to bright, sunny locations or even slightly dappled areas. Whatever types of plants you choose, succulents need well-drained soil. They can thrive in cracks and crevasses, rockeries, and sandy or gritty soils.
Determining the pot size for your succulents’ healthy growth seems quite difficult. However, many professional gardeners recommend a container that is 10% larger in diameter than the width of your succulent. For instance, if your chubby green has a width of 4-inches, a pot with 4.5-inch diameter will be ideal for it.
For the best potting soil for succulents, start with a basic cactus and succulent soil mix, or even an African violet mix, available at most garden centers. Then add some extra ingredients to find the one that will make watering easier, improve the drainage, and hold up a long time without compacting.
