Care Requirements
1. Temperature
· White Graptoveria 'Titubans' is a winter-growing succulent that thrives in warm, dry, and well-ventilated environments.
· Optimal growth occurs between 15–25°C (59–77°F).
· Avoid temperatures below 5°C (41°F) to prevent frost damage.
2. Watering
· Water only when the soil is completely dry, typically once a month.
· Adjust watering for seasons:
o Summer: Provide light shade, good ventilation, and water sparingly (4–5 times a month but without soaking the soil). Excessive watering may cause rot.
o Winter: Reduce watering as temperatures drop below 5°C (41°F). Keep the soil dry when temperatures fall below 3°C (37°F) and avoid going below -3°C (27°F).
3. Light
· Spring and Autumn: Full sun exposure promotes robust growth.
· Summer: Slight dormancy occurs; ensure proper ventilation and light shading.
· General Light Needs:
o White Graptoveria 'Titubans' prefers cool, dry environments with ample sunlight.
o Adequate sunlight and significant day-night temperature differences enhance leaf color vibrancy.
o Lack of sunlight causes leggy growth and dull leaves.
Soil and Repotting
· Soil: Loose, fertile, well-draining sandy soil, such as a mix of leaf mold, garden soil, and river sand in equal parts.
· Repotting: Combine repotting with division during spring. Divide densely growing clusters into groups of 3–4 stems, allow wounds to dry, and replant.
Propagation Methods
1. Leaf Cuttings
· Select mature, plump leaves. Place them flat on moist potting soil with the top side facing up and the back side down.
· Do not cover with soil. Keep in a cool, ventilated area.
· Within ~10 days, new leaves and roots will develop. Bury the roots in soil, water moderately, and provide sunlight for growth.
2. Stem Cuttings
· Use terminal or lateral branches, cutting 3–5 cm segments. Remove lower leaves and let the wounds dry.
· Insert cuttings into moist potting soil. Roots will develop in ~20 days, after which watering can begin. Transplant to new pots when roots reach 2–3 cm.
3. Division
· Divide dense clusters in spring during repotting. Separate into groups of 3–4 stems, dry the wounds, and pot individually.
Additional Care Tips
1. Temperature Control
· Maintain indoor temperatures between 15–25°C (59–77°F).
· Protect from cold in winter and ensure good ventilation in summer to lower temperatures.
2. Sunlight
· Provide ample sunlight. Place indoors in a sunny spot during winter and shield from intense summer sunlight to prevent leaf burn.
3. Watering
· Avoid overly moist conditions. Keep the soil slightly moist but not wet. Strictly control watering during dormancy.
4. Fertilization
· Use fertilizers sparingly. Excess nitrogen may cause leggy growth and dull leaf colors. Opt for phosphorus and potassium-based fertilizers at low concentrations. Apply diluted fertilizer monthly during the growing season.
5. Pruning
· Regularly remove old, withered, diseased, or excessively long branches and leaves. This reduces bacterial growth and maintains an attractive plant shape.
By following these care and propagation guidelines, White Graptoveria 'Titubans' succulents will thrive, producing vibrant leaves and maintaining their ornamental appeal.
