How do I grow Langra mango from graft and what spacing for a new orchard?

Always use grafted (veneer or softwood grafted) Langra plants from a certified nursery, never seedlings, because seedlings are not true to type and take much longer to bear. Grafts start fruiting in about 3 to 4 years versus 6 to 8 for seedlings. For a traditional orchard, normal spacing is about 10 by 10 metres (roughly 40 trees per acre). For higher early returns, medium to high density at around 5 by 5 metres (about 160 plants per acre) with regular pruning is increasingly used, but it needs disciplined canopy management or trees crowd later. Plant at the start of the monsoon in pits enriched with FYM, ensure drainage, and stake young plants. Keep the graft union above soil and remove rootstock sprouts below the union regularly.
