Tuberose Bulbs, commonly known as Rajnigandha or Gul-e-Shabbo, produce tall white flower spikes with a rich sweet fragrance that becomes especially noticeable in the evening. They grow best in warm weather, full sunlight, and loose well-draining soil, making them suitable for 10–12-inch pots, grow bags, borders, and sunny garden beds.
Native to Mexico, Tuberose became popular worldwide for its powerful scent, long-lasting cut flowers, and use in perfumes, bouquets, garlands, and fragrant home gardens.
Tuberose is a rewarding summer flowering bulb once planted correctly. Its tall, scented blooms are ideal for patios, balconies, entrances, and garden corners where fragrance can be enjoyed in the evening.

How to Grow Tuberose Bulbs
When to Plant
- Plant from March to April in most areas of Pakistan.
- Blooms usually appear around 3–4 months after planting, depending on weather, bulb size, and care.
Where to Grow
- 10–12-inch pots, grow bags, sunny borders, or well-drained garden beds.
- Choose a warm, bright place with full sunlight.
- Avoid spots where water stands after watering or rain.
Planting Tips
- Use 2 parts garden soil with 1-part Vermicompost.
- Plant bulbs about 2–3 inches deep, with the growing point facing upward.
- Keep 4–6 inches spacing between bulbs.
- Water once after planting to settle the soil.

Fertilizer & Care
- At planting, mix in Vermicompost to improve soil texture and support root growth.
- During active growth, apply NPK 20 20 20 Fertilizer lightly for healthy leaves and stems.
- Before flowering, apply NPK 5 15 45 Fertilizer lightly to support flower spikes.
- Remove spent flower stems but keep the leaves until they yellow naturally.
After Flowering Care
Once Tuberose flowers fade, do not cut the green leaves immediately. The leaves continue feeding the bulb and help it store energy for the next flowering season.
When the leaves turn yellow and dry, reduce watering. In pots, keep the bulbs on the drier side during dormancy. In garden beds, bulbs can stay in the soil if drainage is good but avoid keeping the area wet for long periods.
