PRO-MIX Pro-Mix African Violet Mix is an indoor growing mix for African violets and other delicate houseplants, designed to support healthy rooting and steady moisture balance. This indoor growing medium focuses on improved air porosity and water retention to keep sensitive plants in a comfortable, consistent root environment.
Made for plants that prefer a lighter, more breathable root zone, Pro-Mix African Violet Mix helps create conditions that support attractive, even growth. The texture is built around improved air porosity and water retention, which is especially valuable for delicate plants that can struggle in heavy, compact media. It’s also suitable for all plants from the Gesneriad family such as Streptocarpus, Episcias and Gloxinias, making it a strong fit for collectors and indoor gardeners growing a range of violet relatives. The result is a mix that supports the look you want in indoor plants, with a clear focus on beautiful foliage and flowers.
A standout feature is MYCOACTIVE technology, described as an exclusive approach that includes a natural plant stimulant to assist the plant’s root system. This root-focused support is designed to increase nutrient and water uptake, helping plants stay more consistent as they establish and grow. With MYCOACTIVE technology, the mix is positioned to stimulate vigorous growth and support greater stress resistance, while also encouraging a larger root system for increased nutrient and water uptake. These benefits are especially useful when you want steady performance from sensitive indoor plants that respond quickly to changes in their environment.
Pro-Mix African Violet Mix also includes an organic-based fertilizer that gradually feeds plants for up to three months, supporting ongoing growth without turning the mix into a complicated input. It’s listed for indoor use and for seed starting and cuttings, making it a practical option when you’re starting new plants, maintaining compact root zones, or keeping a propagation area organized for repeatable results.
This mix is built from sphagnum peat moss, peat humus, perlite, limestone, organic-based fertilizer, and mycorrhizae (PTB297 technology). It’s a good fit for growers who want a purpose-made indoor growing mix with improved air porosity and water retention, MYCOACTIVE technology, and root-support benefits for African violets and other Gesneriad family plants.
Canadian sphagnum peat moss is important because it holds moisture evenly while still supporting air spaces that roots need for oxygen, which makes watering and nutrient uptake more consistent. It is unique because it naturally trends acidic and acts more like a moisture-and-structure foundation than a nutrient source, so it changes root-zone balance in ways other base ingredients do not.
Perlite is important because it increases root-zone oxygen and improves drainage, helping roots stay healthy and active; it’s unique because its main benefit is physical structure and airflow—not nutrients or moisture storage—so it fixes “too wet and compact” root problems in a simple, predictable way.
Yes, when soil is too acidic, limestone can help plants grow better by gently raising pH and supplying calcium so roots can absorb nutrients more smoothly. It’s unique because it fixes the root-zone chemistry itself, which can solve several “mystery deficiencies” at once, but if used when pH is already high it can trigger micronutrient lockout instead.
Mycorrhizae form a living partnership with roots that expands the plant’s effective root reach, helping it gather water and hard-to-reach nutrients more efficiently. They’re important because they improve steadiness and stress tolerance over time, and they’re unique because they physically connect to roots and build a fungal network in the root zone rather than acting like a direct nutrient input.
Organic-based fertilizer is slower because its nutrients are released as the root zone breaks down organic particles over time, so it feeds plants through steady biological conversion rather than instant availability, which is what makes it uniquely good at supporting long-term root health and stability.
Peat humus acts like a sponge and a gentle nutrient holder in the root zone, smoothing moisture and nutrient availability so roots can feed more consistently. It’s important because many “deficiency” symptoms come from unstable water and nutrient swings, and it’s unique because it improves the root environment rather than providing a fast nutrient hit.
