Follow-Up: Overpotting Confirmed as Root Cause of Mold, Rot, and Pests

Melina adds details: careful watering (top 1–2" dry), uses Miracle-Gro soil (some bags moldy), adds peat/vermiculite. Asks for soil recommendations.

Confirmation: Repotting Too Often

"Most people repot too much." Plants thrive rootbound. Avoid repotting unless absolutely necessary (roots cracking pot, severe decline).

Soilless, peat-based mix (Pro-Mix, Sunshine Mix, or homemade: peat + perlite).
Perlite, not vermiculite — vermiculite compacts over time, reducing aeration.
No fertilized bagged soils (Miracle-Gro etc.).

Stop repotting. Use better mix only when truly needed. Your mold/rot/insect cascade started with disturbed, overwet root zones.
