We all understand how difficult it can be to keep succulents alive, and it is even harder to keep them thriving. The biggest factor at play in allowing your succulents to thrive is the soil, because soil holds the key to root growth, nutrient supply. and much more. The soil can either help water flow through the roots like a refreshing drink or let it build up in the pot and cause root rot.
That is why I have developed a reliable succulent-blend that works well in any climate – even the heat of Texas – and suits a wide range of succulent varieties.
This formula has gone through several versions as I learned more about the specific needs of succulents. It is now the mix I use for all the succulents I grow and sell through Gen1 Greenhouse.

Each ingredient plays an important role in supporting plant health:
- Compost adds organic nutrients and beneficial microorganisms to the soil.
- Peat moss holds moisture without compacting, helping maintain a balanced water level.
- Coarse sand improves drainage and provides weight and texture to anchor roots.
- Perlite introduces air pockets and allows excess water to drain freely, preventing root rot.
I include Nelson NutriStar® Cactus and Succulent Plant Food to encourage vigorous growth. It is a well-formulated, slow-release fertilizer that complements the mix when used as directed. This is optional, but it will greatly increase growth.
Where to Find Ingredients
Most of these components are available at local garden centers or hardware stores:
- Compost can be found in bags at our nursery in Nacogdoches, or at other retail stores.
- Peat moss is commonly sold in compressed bales in garden centers or nurseries.
- Coarse sand is available as builder’s or horticultural sand—avoid play sand, which holds water.
- Perlite is found at local retailers and nurseries.
- Fertilizer can be purchased online or in stores that stock the Nelson Plant Food line.
Substitutions and Alternatives
If one or more of the ingredients is unavailable, consider these substitutions:
- Coconut coir may be used in place of peat moss for a more sustainable option.
- Well-rotted leaf mold or a high-quality, peat-based potting soil (without moisture-control additives) can substitute for compost.
- Pumice or crushed lava rock may be used instead of perlite for added drainage and aeration.
This soil mix is suitable for a wide range of succulents and has performed consistently well under the conditions of East Texas. Whether used in containers or garden beds, it offers a healthy growing environment that encourages strong root systems and vibrant foliage.
For those beginning their journey with succulents or looking to improve their soil practices, this blend offers a reliable foundation for success.
