How fast does a cashew tree grow?
The overall fruit set of seedling trees generally ranges from 3% to 12%. However, cashew flowers can be hand pollinated to increase fruit set. The time from flowering to cashew nut maturity is about 50 to 60 days and it takes another 20 to 30 days for the cashew apple to mature, depending upon ambient temperatures.
What conditions are needed to grow cashews?
The distribution of cashew is restricted to altitudes upto 700 m above mean sea level where the temperature does not fall below 20°C for prolonged period. Areas where the temperatures range from 20 to 30°C with an annual precipitation of 1000 – 2000 mm are ideal for cashew growing.
Are cashews water-intensive?
