When purchasing a bare-root cactus, spurge, succulent or caudex plant, one of the main concerns is how to encourage root growth. They are tough and incredibly resilient plants, but they may need a little help establishing themselves in a new environment.
Preparing the Potting Mix
The first step to encouraging root development is to prepare the right potting mix. Succulents require a well-draining mix to prevent waterlogging and root rot. A good mix consists mainly of draining material such as pumicestone Or black volcanic stone and the rest is potting soil for indoor plants, it is also good to put a little coal for its antifungal effect. Such a mixture provides the right balance between drainage and nutrients. If you are looking for a ready-made solution, you can use our homemade cactus soil for cacti and euphorbias that need even more drainage or our homemade succulent mix.
Using a rooting hormone
Cutting hormones can be very beneficial in promoting root growth. These hormones are available in powder, liquid or gel form. The cutting or bare root should be dipped in rooting hormone according to package directions before planting. This stimulates the growth of new roots at the point of contact.
Planting
Place your plant in the potting mix. Do not bury it too deeply, only the lower part should be covered. If it's a cutting, allow the cut end to heal and dry for a few days to a few weeks (depending on size) before planting. This helps prevent rot.
Waiting before watering
After planting, do not water immediately. This allows any damaged or cut roots to heal and helps prevent rot. Wait about 1 to 2 weeks before you start watering.
Start watering carefully
When you start watering, do so sparingly. Overwatering can cause root rot and kill your plant. Water thoroughly, letting the water drain completely each time, then allow the soil to dry completely before watering again.
Providing suitable conditions
Although it does not directly address root development, providing the right conditions can promote healthy root growth. Keep your plant in a warm environment with plenty of light. Using a heating mat can help with root formation.
Patience
Patience is a virtue, especially when it comes to cactus root growth. Root development in cacti, succulents, euphorbias and caudex plants can be a slow process. It can take several weeks to a few months for a cactus to establish a strong root system, depending on the species and conditions. It is important not to disturb the cactus during this time, as this may damage the new roots. After about 2 to 3 weeks, you can check root development by gently pulling on the plant. If it resists, it means that roots are forming. However, try not to do this frequently, as it may harm the developing roots.
Fertilization
It is good to remember that cacti, succulents, euphorbias and caudex plants are not the most fertilizer intensive. Once the plant has established roots, it can benefit from a supplement of fertilizer to promote its overall health and growth. However, too much fertilizer can harm the roots. Fertilizer should therefore be used sparingly according to package directions. We like to use liquid algae with cacti, an organic and local fertilizer which does not risk burning the roots.
Conclusion
Root growth is an essential aspect of establishing a cactus, succulent, euphorbia and caudex plant in a new environment. By following these steps, you can help your plants develop a strong, healthy root system. Remember: patience is key. They are slow growing plants and it can take time for roots to develop. But with the right care and a little time, your cactus, or other succulent, will soon be thriving in its new environment.
