Roselle cultivation techniques

1. Soil requirements: Roselle is a plant that fears waterlogging but not drought. It is best to choose a sunny site with deep soil and good drainage, using sandy loam for planting. Apply 1000-1500 kg of farmyard manure per mu.

2. Planting density: According to soil fertility, plant spacing and row spacing: 0.6-0.8 cm, with 1300-1500 holes sown per mu being appropriate.

3. Sowing time: Soak the seeds for 12 hours before sowing. Sowing from mid-to-late April to early May is more suitable. For dibbling, put 3-4 seeds per hole; for raising seedlings in nutrient pots and transplanting, transplant promptly when the seedlings are 12-15 cm tall.

4. Field management: (1) Timely pest control: Seedlings emerge 5-7 days after sowing. Spray with 2.5% lambda-cyhalothrin at 50 ml/mu to control pests. Pesticides must be sprayed before flowering. Spraying pesticides is strictly prohibited during the flowering period, so as to avoid pesticide residue remaining in the calyx and affecting product quantity. (2) Timely thinning, final thinning, and pinching: When the seedlings grow to 10-15 cm, thinning should be carried out, removing weak and diseased seedlings, leaving only one healthy seedling per hole, and removing the rest to fill gaps in missing holes. Thinning should not be too late, otherwise it will affect seedling growth. When the seedlings are 80 cm tall, pinching should be carried out to promote strong branches, more flowers, and thicker calyces. (3) Fertilization and irrigation: Roselle does not need large amounts of water and fertilizer, but land with poor fertility should be appropriately topdressed. Apply compound fertilizer 20 kg, urea 8 kg, and zinc fertilizer 5 kg per mu by watering to promote seedling growth; before flowering, apply compound fertilizer 30 kg and potassium sulfate 20 kg per mu to meet the needs of flowering. (4) Intertillage, weeding, and drainage: When the plants are 30 cm tall, combine topdressing with earthing up, and carry out intertillage 2-3 times at the appropriate time. In summer, due to abundant rain, weeds grow densely, so weeds must be pulled by hand to avoid competing with roselle for fertilizer and water. During the rainy season, pay attention to digging ditches for drainage to prevent seedling death and root rot.

5. Harvesting and sun-drying: Roselle is mainly harvested for its calyces. Entering mid-to-late October, when the seeds inside the flower buds become hard or brown, cut off the fruiting branches, remove the calyx together with the fruit, and after shrinking, remove the calyx. When removing the calyx, a thin metal tube can be used to push out the round fruit. The calyx must remain intact and must not be split or peeled off. Roselle is acidic and very prone to mold, so it must be sun-dried promptly.
