From our crop reference
Alder is a tree crop, a perennial. Sow it in Mar–Apr and expect to harvest in 15–25 years. It wants a pH of 5.0–7.0 (slightly acid) and 10–28°C. Plant at 3 × 3 m. A good crop returns around 8–12 m³/yr. Watch for leaf beetle, canker.
Growing Alder5 sentences from our guides, quoted exactly
Woody Plants: Examples: Alder (Alnus incana), American elderberry (Sambucus canadensis), Red maple (Acer rubrum), and Winterberry (Ilex verticillata).
Options: Grow under existing forest canopy or plant multipurpose shade trees (e.g., alder, grevillea) ensuring they are not so dense as to suppress growth.
Shade and intercropping Shade management is one of the most important aspects for success in the Brahmaputra Valley: Natural shade: Understorey cultivation beneath existing trees (e.g., alder, banjhi) works well.
Practical approaches: Maintain a light, open canopy using shade trees like alder, silver oak, or native species that drop some foliage seasonally.
Aim for 70–80% shade using plantations of trees (e.g., alder, paulownia or eucalyptus with managed canopy) or artificial shade nets.
