Pro-Mix BX

Mycorrhizae are beneficial fungi that colonize plant roots, effectively extending their reach to absorb more water and nutrients. This symbiotic relationship helps plants establish stronger root systems, leading to better overall growth and increased resilience against transplant shock.

Pro-Mix BX is versatile enough for both. Its lightweight, consistent texture provides a great environment for seed germination, while the added nutrients and drainage components make it equally effective for potting up seedlings or transplanting established plants.

This mix includes a wetting agent and limestone to balance pH, but it is not a heavily fertilized soil. You will need to begin a regular feeding schedule with your preferred fertilizer shortly after planting to ensure your plants get the specific nutrients they need.

Yes, it works well for both. Because it is lightweight and offers excellent drainage, it is a popular choice for indoor containers where preventing root rot is a priority, as well as for greenhouse vegetables and outdoor annuals.

A 2.8 cubic foot bale is quite substantial and will typically fill about 10 to 12 standard one-gallon nursery pots. Keep in mind that the mix is compressed in the bale, so it will fluff up significantly once you break it apart and add a little water.

You don't need to add anything. This is a complete, professional-grade growing medium designed to be used straight out of the bag. Adding heavy garden soil can actually disrupt the drainage and aeration properties that make this mix effective.
