4000 that is too much, may i know what is the distance between each of them?
My friend told me that you can plant mahogany in 1.5meters distance in all sides.
Swietenia mahogani. Mahogany grows to an average of
30-40ft./9.1-12.2 meters high
2 ft./0.6 meter trunk;
20-30ft./6.1-9.1 meters canopy.
Even with 1.5 meters distance all around, the trees will overlap because the canopy is between 6.1 meters and 9.1 meters.
Imagine 4 people standing shoulder to shoulder in a square pattern with their umbrellas closed. Now when each person open their umbrella, and stay in the same place, the canopies of their umbrellas will overlap each other.
So, I think even 4000 trees may be too crowded in a hectare farm. A crowded mahogany farm will restrict air circulation.
