Preparing the Land for Njahi Cultivation
Njahi thrive in well-drained soil with a pH range of 6.0 to 7.0. Here’s how to prepare your land for optimal growth:
1. Clear the Land: Remove any weeds, debris, or large rocks from the planting area.
2. Tilling the Soil: Use a tiller or hand hoe to loosen the soil to a depth of 6-8 inches. This promotes good drainage and root development.
3. Soil Amendments: Incorporate organic matter, such as compost or manure, to improve soil fertility and structure.

3. Depth: Sow seeds at a depth of 1-2 cm.
4. Watering: Water the seeds thoroughly after planting, ensuring the soil remains moist.
Nurturing Your Njahi Plants: Essential Care Practices
Njahi plants require consistent care to thrive. Here are some essential practices:
- Watering: Water your njahi plants regularly, especially during dry periods. Aim for 1-2 inches of water per week.
