21. Which leafy vegetables grow best in vertical towers?
Spinach, lettuce, amaranthus (chaulai), coriander, methi (fenugreek), and mustard greens are ideal. They grow fast and require less root depth.
22. Should leafy greens be directly sown or transplanted?
Direct sowing is preferred because they have delicate roots and quick maturity. Transplanting may cause transplant shock or stunted growth.
23. How often should I harvest leafy greens?
Begin harvesting 25–30 days after sowing. Harvest outer leaves first to allow new growth from the center.
24. Why are my leafy greens growing tall and thin?
This is a sign of inadequate light ("legginess"). Move your tower to an area with at least 4–6 hours of direct sunlight.
25. Can I regrow leafy greens after harvesting?
Yes, especially spinach, amaranthus, and methi. Harvest by snipping 1 inch above the crown to allow regeneration.
26. Do leafy greens require a lot of fertilization?
No, they thrive on moderate feeding. Use vermicompost or compost tea every 10–15 days.
27. Why do leaves turn yellow or pale?
This indicates nitrogen deficiency or overwatering. Feed nitrogen-rich compost and reduce watering frequency.
28. Can I grow mixed greens in one tower?
Yes, as long as they have similar water and sunlight requirements. It adds variety for daily harvests.
29. Is pinching needed for leafy greens?
Not mandatory. But regular harvesting (snipping outer leaves) helps bushier growth and prolongs yield.
30. How do I control pests on leafy greens organically?
Spray diluted neem oil weekly. Inspect the undersides of leaves for aphids, caterpillars, and whiteflies.
