Prof. Samuel Fitzgerald, Ph.D.Refresh succulent soil every other year to avoid any problems. Over time, soil compacting reduces air spaces for roots. Nutrients are depleted, leaving plants starving. Salt from water and fertilizers accumulates, creating a toxic environment in which to grow. Replace the soil promptly to prevent any problems and maintain healthy growing conditions for your plant.
Water Absorption Issues
- Water pools on surface instead of soaking in
- Soil pulls away from container edges
- Takes over 30 seconds to absorb water
Mineral Buildup Signs
- White crust forms on soil surface
- Yellow or brown leaf tips appear
- Visible salt crystals around drainage holes
Physical Soil Degradation
- Hard compacted surface that resists probing
- Fungal growth or mold visible
- Earthworm absence in outdoor containers
Renew soil using appropriate methods. Carefully dispense old soil while preserving root structure. Use sterilized scissors to remove dead roots. Select a new mix, prepared according to plant requirements. For compact soil conditions, add additional perlite to the mix. If the roots outgrow the same pot, stay in the same pot. Water five days later.
Increase the soil's longevity between replacements. Use topdressing to help minimize evaporation, and flush pots quarterly to remove salts. Use chopsticks to aerate compacted soil. Use mycorrhizal fungi to enhance nutrient uptake. These practices promote healthier conditions for a longer duration.
Don't make the mistake of replacing (existing) soil. Old soil is a habitat where pathogens can persist. Do not fertilize for six weeks after the transition. Clean pots before using them again. Ensure the soil pH matches the conditions of your previous growing experience. Your plants should maintain a seamless transition when given proper care and attention.
