1. Ideal Soil Composition

The Perfect Blend:

• 60% Organic Matter (peat moss/coco coir for moisture)
• 30% Drainage Material (perlite/pumice)
• 10% Nutrients (compost/worm castings)

Why It Works:

• Prevents waterlogging (root rot risk ↓ by 70%)
• Allows oxygen to reach roots
• Supports rapid growth

Expert Tip: The University of Maryland Extension recommends 2:1 potting mix to perlite ratio for trailing plants.

2. DIY Soil Mix Recipes

Basic Mix (Budget-Friendly)

[Illustration: Soil components graphic]

– 2 parts potting soil

– 1 part perlite

– 1/2 part peat moss

Premium Mix (Optimal Growth)

• 1 part orchid bark
• 1 part coco coir
• 1 part perlite

3. Best Commercial Soils

Top Picks:

1. Espoma Organic Potting Mix (pH balanced)
2. FoxFarm Ocean Forest (with beneficial microbes)
3. Miracle-Gro Indoor Mix + extra perlite

Avoid:

• Heavy garden soils
• Moisture-control mixes

4. pH & Nutrient Needs

• Ideal pH: 6.0–6.5 (slightly acidic)
• Key Nutrients: Nitrogen (N) for leaf growth

Test & Adjust:

• Use a $10 pH meter
• Lower pH with peat moss
• Raise pH with lime

Science Note: A Cornell University study shows Tradescantia absorbs nutrients best in this pH range.
