How Do You Grow Cashew Nuts

You grow cashew nuts by planting fresh raw cashew seeds in warm tropical conditions and caring for the young trees until they bear fruit.
 
That’s the short answer, but growing cashew nuts is a bit more involved than just sticking a seed in the ground.
 
Cashew trees need heat, patience, and plenty of space, and they’ll only thrive outdoors in tropical climates.
 
If you’ve ever wondered how do you grow cashew nuts from scratch, this post will walk you through the whole process, from planting to harvesting.
 
In this post, we’ll cover how cashew trees grow, the conditions they need, and how to grow cashew nuts step by step so you can enjoy your own harvest.
 
Let’s get into it.
 

How Do You Grow Cashew Nuts?

Growing cashew nuts starts with a fresh, raw cashew seed, also called a nut, that hasn’t been roasted or processed.
 
Here’s what the process looks like in a nutshell (pun intended):
 

1. Start With a Raw Cashew Seed

You can’t grow cashew nuts from the roasted, salted ones you buy at the store because those won’t sprout.
 
You need raw cashew seeds, which you can sometimes find at nurseries or specialty suppliers.
 
Keep in mind the seed is encased in a tough shell that contains a caustic oil, so handle it carefully.
 
Many growers plant the seed shell and all, while others crack it open with proper protection to speed up germination.
 

2. Plant in Warm Soil

When you grow cashew nuts, warmth is everything.
 
Plant your seeds about two inches deep in well-draining sandy soil, and keep the soil moist but not soggy.
 
Cashew seeds germinate best when temperatures stay between 70°F and 85°F.
 

3. Care for the Seedling

Once the seedling pops up, give it full sun and steady water.
 
Young cashew trees are sensitive to cold and waterlogging, so protect them from both.
 
This is also the stage where you’d transplant your seedling to its permanent spot if it started in a pot.
 

What Conditions Do Cashew Trees Need to Grow Nuts?

How do you grow cashew nuts successfully?
 
You give the tree what it naturally craves, which is a tropical environment.
 
Here’s what cashew trees need:
 

1. Tropical Warmth

Cashew trees grow best in USDA zones 10 through 12 and simply can’t tolerate frost.
 
They love heat and humidity, which is why cashew farms are common in places like Brazil, India, and Vietnam.
 

2. Full Sun and Good Drainage

Give your cashew tree at least six hours of direct sunlight daily.
 
And since cashew trees hate soggy roots, sandy, well-draining soil is a must.
 

3. Plenty of Space

Cashew trees can grow 20 to 40 feet tall with a wide canopy, so plant them well away from buildings and other trees.
 
If you’re growing cashew nuts in a container, choose a dwarf variety and a very large pot.
 

How Long Does It Take to Grow Cashew Nuts?

Patience is the name of the game here.
 
Cashew trees grown from seed usually start producing nuts in about three to four years, though some take up to five.
 
Grafted trees can fruit a little sooner, which is why many growers prefer them.
 
Once a tree matures, it produces cashew apples with the nut attached at the bottom, and each apple typically holds one nut.
 
Harvest season usually runs from late winter into spring, depending on your region.
 
When the cashew apples turn red or yellow and fall, that’s your cue to collect them and carefully remove the nuts.
 
Roasting is essential before eating because the shell contains irritating oils, so never skip that step.
 

So, How Do You Grow Cashew Nuts?

You grow cashew nuts by planting raw cashew seeds in warm, well-draining soil, giving the tree full sun and tropical heat, and waiting a few years for your first harvest.
 
It’s a slow but rewarding process that rewards anyone lucky enough to garden in a tropical climate.
