Orchid soils

To choose the right potting mix for your orchids, I advise you to opt for substrates specifically formulated for them. These mixtures are generally composed of pine bark, sphagnum moss, perlite, or clay pebbles, offering excellent aeration and good drainage, which are essential for the roots of these epiphytic plants. In practice, brands like Or Brun or Growth Technology offer very effective solutions.

The main difference between Or Brun and Growth Technology often lies in their composition and philosophy. Or Brun is a French brand known for its natural products and often focused on organic cultivation, with balanced mixtures. Growth Technology, particularly with its Orchid Focus Substrate, specializes in orchid nutrition and growth, offering high-performance substrates that are often enriched to stimulate flowering. If I had to choose, I would say that Or Brun is an excellent choice for a more natural approach, while Growth Technology is ideal for optimizing performance.

Orchid substrate has several crucial functions. Firstly, it serves as a physical support for the plant, allowing it to anchor itself. Secondly, and this is very important, it ensures excellent root aeration, preventing asphyxiation and rot, a common problem with classic potting soils. Finally, it retains just enough moisture and nutrients for the plant to develop without excess. This is why a good substrate is essential for the health and flowering of your orchids.

To know if your potting mix is suitable, I invite you to observe your orchid carefully. If the roots are green and plump, if the plant produces new leaves and flowers, that's a good sign. Conversely, if the roots blacken, soften, or if the plant stagnates and does not flower, it is likely that the substrate is not suitable, often due to a lack of aeration or excess moisture. A good substrate should be light, airy, and not compact.

To repot an orchid, I advise you to do it ideally after flowering. Start by gently removing the orchid from its old pot, remove the old substrate, and cut off any dead or damaged roots. Then, place the plant in a new, slightly larger pot, distributing the new substrate, such as Orchid Focus Substrate, around the roots without compacting it too much. Make sure the plant's crown is level with the substrate. Do not water immediately after repotting; wait a few days.

The most common mistake is to use a universal potting mix. This type of potting mix retains too much water and does not allow sufficient aeration for orchid roots, which often leads to rot. Another mistake is to compact the substrate too much during repotting, which compromises aeration. Finally, remember to repot regularly (every 1 to 2 years) because the substrate degrades over time and loses its draining properties.

With a substrate adapted to orchids, watering should be done by soaking. I recommend immersing your orchid's pot in lukewarm water for 15 to 20 minutes, then letting it drain completely. The frequency will depend on the season and ambient humidity, but generally, I water when the substrate is dry to the touch. This method ensures good hydration without saturating the roots.

Yes, absolutely! Orchid Focus Substrate is an excellent choice for most orchids. It is formulated by Growth Technology, a brand renowned for its expertise in plant nutrition. This substrate is designed to offer a perfect balance between aeration, drainage, and moisture retention, which is crucial for root health and stimulating flowering. It's a product I recommend very often.
