  • Plant the seeds 10 cm deep to allow room for the roots to grow.
  • The cashew trees should be spaced 9.1 m apart in order to flourish.
  • The finest outcomes come from using the freshest seed possible.
  • Deep soil layers and proper drainage are necessary for cashew tree growth and strong harvests.

During their tenth year, they reach full production and continue to produce for another 20 years. A cashew nut harvest takes place between February and May. The cashew tree has to be at least 5-7 years old to generate a steady yield and harvest. A mature cashew tree may reach heights of 6–12 meters (20–40 feet). 

Average Cashew Tree Production by Age

  • Cashew trees that are 3 to 5 years old produce 2 to 3 kilograms of raw cashew nuts per tree.
  • 6 to 10 years old Cashew trees produce 4-5 kilograms of raw cashew nuts per tree.
  • 5 to 10 kg of raw cashew nuts may be harvested from each 11–15-year-old tree.

Climate and location

The growth region for cashews has temperatures between 10 and 40 C. Without protection, they will struggle to live when the temperature falls below 50°F. As a result, you must take steps to shield your tree from cold spells.

You should plant either next to a warm building wall that faces south or west. Cold and frost damage will be reduced either way. Locations with a south or westerly orientation often get more warmth and are less likely to freeze than those with a north or east orientation.


Once Cashew trees are established, they can tolerate drought to some extent. you should water the young trees frequently. Its growth rate will double with weekly watering, helping the trees to take root more quickly. Fruit production is also encouraged by regular irrigation.

You might need to water your trees twice a week in warmer climes. Don’t overwater the plants because doing so might cause harm or even cause the plants to die. You should also temporarily stop watering during the intense rain.


You can better protect your cashew tree from frosts and cold weather if its base is mulched. It can also prevent weeds from sprouting and maintain soil moisture. Sandy soils benefit the most from this. Mulch can be helpful in the defense of plants against soil-borne pests.

Black polythene wraps can be installed at the base of your tree if you don’t want to routinely work organic stuff around it. It will stop providing additional nutrients that organic mulch does which offer some protection from frost. Alternatively, you can use stones and tiny pebbles around its base. These are equally useful but look nicer than the black plastic covering.


you should frequently keep fertilizing during the growing season, especially when the trees are blooming and producing fruit.  Use a fertilizer that is rich in zinc, phosphorus, and nitrogen. The quantity you apply will vary depending on the tree’s size and the climate in which it is growing. 

During the growth period, you should nourish your tree once every two months. Furthermore, you can annually modify the soil around the base of mature cashew trees with compost or farm manure.

Pruning and Training

If any sprouts appear from the roots of the cashew tree during the first year, remove them. These sprouts will absorb essential nutrients and affect the growth of trees. You should trim damaged and unhealthy branches regularly. This will stop the spread of illnesses and deter pests from attacking your trees.

Cut off tangled and congested branches to promote growth. A cashew tree branch can be trained during its first few years to assume the right shape. The majority of this shaping will include cutting away lower and twisted branches. Late summer and early fall are the best times to prune.


Occasionally pull weeds from around the cashew tree’s base. The tree will be able to absorb more moisture and nutrients. You can avoid the growth of weeds if you have a row of cashew trees, by establishing grass strips between the tree lines. Those strips of grass will need to be mowed often.

The lifespan of the Cashew Tree

The cashew tree has a 20 to 25-year lifetime. If you take care of your cashew tree, it will live longer and grow better. It requires sunlight, water, nutrients, and an environment free of pests to grow well. The cashew tree can grow up to 10 to 12 meters. However, some trees can reach heights of 14 meters. 

The health benefits of the Cashew Tree

Cashew nuts are a highly healthy food that has great health advantages. These kidney-shaped nuts may treat a number of conditions, from heart disease to digestive problems. Additionally, consuming cashews frequently will provide you with the necessary nutrients.
