It's wonderful to see your enthusiasm for farming and your dedication to growing your own food. Utilizing the small space in front of your house for planting yams in cement bags is a creative solution, and it's great that you're seeking professional advice to ensure success. Your commitment to preserving pumpkin seeds from last year and seeing them sprout after just 7 days is impressive. It's indeed a rewarding feeling to be closer to nature and to witness the growth of your plants. Keep up the good work, and I look forward to hearing more updates on your farming journey!
