Flortis Orchid Substrate

🌱 Flortis Orchid Substrate: The Ideal Foundation for Strong Roots and Spectacular Blooms ✨

The Flortis Orchid Substrate is a technical mix specially formulated to meet the physiological needs of the most popular epiphytic and semi-epiphytic orchids, such as Phalaenopsis, Cattleya, Dendrobium, Oncidium and Vanda (when grown in a pot). Developed by plant nutrition specialists, this growing medium provides the perfect balance of aeration, moderate moisture retention and structural stability, ensuring that your plant's root system develops healthily and free from suffocation or rot.

In their natural habitat, epiphytic orchids live attached to the trunks of rainforest trees, where their roots are exposed to the air, receiving water from the rain and drying quickly in the wind. By using Flortis Orchid Substrate for pot cultivation, you recreate this natural environment very faithfully, allowing ideal air circulation inside the pot and preventing excess moisture from building up around the roots.

✨ Main Benefits of Flortis Orchid Substrate

• Efficient Drainage and Superior Aeration: Its selected pine bark base prevents the substrate from compacting, creating air pockets that are vital for the breathing of the aerial roots.
• Balanced Moisture: It retains the ideal amount of water needed to keep the root system fresh between waterings, reducing the risk of the plant becoming dehydrated.
• Long-Lasting, Stable Structure: With slow-decomposing pieces of pine bark, this substrate keeps its physical structure intact for long periods, reducing how often you need to repot.
• Ready to Use: A balanced, sanitised formulation, free from pests, fungi or harmful substances that could compromise the health of your orchids.

🪵 Composition and Physical-Chemical Properties

The formulation of Flortis Orchid Substrate has been carefully designed to offer a light rooting environment with high porosity. Its base is made of high-quality graded pine bark, combined with selected fractions of fibrous peat and perlite. The pine bark provides the macro-porosity needed for air to pass through, while the peat and perlite help to retain the nutrients applied during feeding, releasing them gradually to the plant.

This physical balance means that, after each watering, excess water drains quickly through the pot's drainage holes, avoiding waterlogging. In addition, the pH of Flortis Orchid Substrate is adjusted to a slightly acidic range (between 5.5 and 6.5), which is the optimum level for orchids to absorb macronutrients and micronutrients efficiently.

🪴 How to Repot and Grow with Flortis Orchid Substrate

Repotting is a crucial step in orchid care and should preferably be done every 1 to 2 years, or whenever the old substrate shows signs of breaking down. The ideal time to use Flortis Orchid Substrate is in early spring or just after flowering has finished, when the plant begins to produce new roots and shoots.

1. Preparing the Plant

Carefully remove the orchid from its old pot. Gently wash the roots with lukewarm water to remove all residue from the spent substrate. Using sterilised pruning scissors, cut off all dry, brown, soft or damaged roots.

2. Choosing and Preparing the Pot

Use a transparent pot with multiple drainage holes in the base and sides. A transparent pot lets you monitor the colour of the roots (which turn silvery when they need water and green when they are hydrated) and allows light to reach the photosynthetic roots.

3. Applying Flortis Orchid Substrate

Place an initial layer of Flortis Orchid Substrate at the bottom of the pot. Position the orchid in the centre, making sure the base of the plant sits level with the top edge. Fill the empty spaces around the roots with more Flortis Orchid Substrate, tapping the side of the pot lightly so that the material settles firmly, but without pressing it down too hard.

🧪 Feeding and Substrate Maintenance

A quality substrate such as Flortis Orchid Substrate works as an excellent support medium and retains moisture, but it requires regular nutritional supplementation to ensure vigorous growth and abundant blooms. As pine bark is an inert medium with low natural fertility, applying high-quality liquid fertilisers is essential.

For the vegetative growth stage, when the orchid is producing new leaves and roots, we recommend regular application of Orchid Focus Grow fertiliser. This formula, rich in nitrogen and micronutrients, stimulates the strengthening of cell structures and the growth of robust roots in Flortis Orchid Substrate.

When the plant enters the flower induction and development stage, switch to Orchid Focus Bloom fertiliser. With a higher phosphorus and potassium content, Orchid Focus Bloom promotes the formation of strong flower spikes, healthy buds and vibrant, long-lasting flowers.
