Frequently Asked Questions
How do I know when a plant is too root-bound and actually needs repotting?
A plant becomes dangerously root-bound when roots push out through drainage holes, lift the main crown out of the container, or split plastic pot walls. Additional warning signs include water running straight through the pot without soaking in, halted top growth during spring, and foliage wilting within hours of watering. When these signals appear, upgrade to a pot that is 1 to 2 inches larger in diameter.
Should I break up the root ball when repotting plants that prefer tight pots?
Avoid aggressive root tearing or cutting for species that prefer restricted root conditions. Lightly massaging the outer lower edges of the root ball is sufficient to encourage new roots to expand into fresh potting mix. For sensitive species like clivias, Hoyas, and African violets, leave the core root mass completely intact during repotting to prevent transplant shock.
How do I feed root-bound plants when there is little soil left in the container?
Because root-bound containers hold less potting soil to retain organic nutrients, feed your plants with a water-soluble liquid fertilizer diluted to half strength every two to four weeks during active spring and summer growth. Always apply liquid fertilizer to damp soil rather than bone-dry roots to avoid root burn.
What happens if I place a plant that likes tight pots into an oversized container?
Placing tight-pot enthusiasts into oversized containers leaves massive soil areas unpenetrated by roots. This excess soil holds standing water for weeks, creating anaerobic conditions that cause severe root rot, foliage drop, fungal diseases, and a complete cessation of flower production.
