Keep the soil consistently moist but not waterlogged. Allow the top 2-3 cm of soil to dry out slightly between waterings. Reduce watering significantly during the dormant period.

Avoid getting water on the leaves to prevent fungal issues. Ensure good drainage to prevent root rot.

Remove spent flowers regularly to promote continuous blooming and prevent seed formation, which can weaken the plant. Trim away any yellowing or damaged leaves as they appear.

After flowering, you can cut back the foliage to encourage a dormant period if desired. This also helps maintain plant shape.

Propagate Gloxinia major from leaf cuttings or stem cuttings. Take a healthy leaf, cut the stem to about 2-3 cm, and insert it into moist potting mix. Alternatively, use stem cuttings.

Keep cuttings warm and humid until new growth appears. Division of tubers is also possible during repotting.

Repot Gloxinia major annually or every other year in spring, just as new growth begins. Use a well-draining potting mix, such as a peat-based mix with added perlite.

Choose a pot that is only slightly larger than the current one. Gently remove the plant, inspect the roots, and repot at the same depth.
