🪴 Care & Maintenance Guide

🌞 Light
Full sun (6+ hours daily) is essential for abundant flowering.
Insufficient sun leads to fewer blooms and leggier growth.

💧 Water
Keep evenly moist while establishing.
Once mature, it becomes drought tolerant.
Allow soil to dry slightly between waterings.
Overwatering can reduce flowering.

🪨 Soil
Requires well-draining soil.
Performs best in sandy or light mixes.
Avoid heavy, compacted soil.

🌡️ Temperature
Thrives in warm climates.
Protect from frost or freezing temperatures.
Cold stress may cause leaf drop but plants often recover.

🌿 Feeding
Regular feeding during active growth promotes continuous blooming.
Use balanced or bloom-enhancing fertilizer every 4–6 weeks in growing season.
Avoid excess nitrogen.

✂️ Pruning
Prune after flowering cycles to shape and control growth.
Can be trained to climb, cascade, or form a dense shrub.
Use gloves due to thorns.

⚠️ Common Issues

Few blooms: insufficient sun or too much water
Yellow leaves: poor drainage or overwatering
Excess foliage growth: too much nitrogen fertilizer
Leaf drop: temperature stress or relocation shock
