Repotting

Rarely needed. Only repot if soil dries in <3 days after thorough watering.

Mealybug Treatment

  1. Prune off ⅓ of each stem—this removes many bugs.
  2. Spray entire plant (tops and bottoms of leaves, stems) with: 5 parts water, 1 part isopropyl alcohol, squirt of liquid soap. Drench until dripping.
  3. Repeat weekly until no bugs seen.

Ongoing Care

  • Bright window (some direct sun okay).
  • Water when soil surface is almost dry.
  • Cool temps preferred.
  • Remove yellow leaves as they appear.

Consistent treatment and good culture will restore your gardenia.
