Plant Explosion Soil Mix

While specifically engineered for aroids like Monsteras and Philodendrons, this mix is excellent for any tropical houseplant that requires high drainage and oxygenation. If you have plants prone to root rot, the airy, chunky texture will provide the necessary root zone health they need.

You can use it either way. It is formulated to be a complete soil-free substrate for rare plants, but it also works perfectly as an amendment if you prefer to blend it 50/50 with your existing potting soil to improve aeration.

Horticultural charcoal acts as a natural filter within the substrate. It helps absorb impurities, prevents the buildup of odors, and keeps the root zone fresh by inhibiting the growth of harmful bacteria.

The mix is designed to be fast-draining to prevent rot, but the inclusion of worm castings and organic components helps retain enough moisture for healthy root uptake. You may find you need to water slightly more frequently than with dense, peat-based soils, but your plants will benefit from the increased oxygen.

Plant Explosion includes worm castings and a gentle, sustained-release fertilizer to support initial growth. Depending on your plant's specific needs and growth stage, you may choose to add a balanced liquid fertilizer during the active growing season.

Rare tropicals naturally grow in loose, porous forest floor debris rather than dense dirt. A chunky texture creates air pockets around the roots, which is essential for preventing compaction and ensuring the roots receive the oxygen they need to grow strong and rot-free.
