Almond Tree Growing Criteria

Almond Tree Growing Criteria

Successfully cultivating these trees requires careful attention to specific criteria. This includes six factors: light, soil, water, temperature, fertilization, and pollination.


The almonds fruit tree thrives in ample sunlight, requiring at least 6 to 8 hours of direct sunlight daily. This light exposure helps stimulate robust flower and fruit production.

Insufficient light can lead to weakened branches, decreased productivity, and overall diminished health.

Seasonal variations, such as the angle and intensity of sunlight, also impact the trees. To ensure your trees soak up the sun, select a sunny spot in your garden, away from shading structures or other tall plants.


Just like a chef carefully chooses the finest ingredients, almond trees need the right soil type to flourish. Opt for well-draining ground with a slightly acidic to neutral pH level, which is between 6.0 to 7.5.

A sandy loam or loamy soil texture is also often preferred, providing a harmonious blend of water retention and adequate drainage.

Amending your wet soil with organic matter enhances its drainage and nutrient-holding capacity, providing a nourishing foundation for your almond tree’s roots.


The next thing on our list is water. The trees have a thirst for consistent moisture, especially during the growing season and when almond nuts are forming.

Still, too much moisture can spell trouble in the form of root rot. Thus, employing drip irrigation is the go-to method, supplying the trees with the steady, deep watering they crave.

As a simple guideline, you should offer young trees a depth of around 1 to 2 inches of water at least once a week.

Once they are established, they become more drought-tolerant. Water mature trees deeply every two to three weeks during the growing season.


These trees are like Goldilocks; they prefer temps that are just right. They thrive in the Mediterranean climate with warm, dry summers and mild, wet winters.

The optimal temp range for almond trees is roughly between 60 to 80°F (or 15 to 27°C) during the growing season.

Excessive heat during the flowering period can lead to poor pollination, impacting fruit sets.

Plus, cold hardy almond trees also require a certain number of chilling hours (typically 300 to 600) during winter for proper flowering and fruit development.


Regular fertilization is a must for any trees and plants, and almonds are no exception. The timing and composition of fertilization are key considerations.

Using balanced fertilizers rich in essential nutrients like nitrogen, phosphorus, and potassium in the early stages is always highly recommended.

Once in the fruiting stage, a one-time treatment of approximately 2 pounds of urea is often sufficient to sustain the tree’s nutrient requirements.


Though some almond tree varieties are self-pollinating, most of them rely on cross-pollination with other trees of different types.

The synchronous blooming of almond blossoms necessitates the timely presence of pollinators as the bees traverse orchards, transferring pollen from one flower to another.

To foster a successful process, plant at least two compatible varieties near each other, providing the honey bees with easy access to both.

Almond Tree Harvest Process

Almond Tree Harvest Process

The almond harvest process is a carefully orchestrated dance between nature and technology, ensuring the final product is not only delicious but also of the highest quality.

Here is a brief instruction on the intricate steps involved in harvesting these sweet kernels.

Step 1: Harvesting almonds

  • Wait for the hulls to split apart, revealing the light-colored shell.
  • Harvest the almonds promptly to prevent birds and insects from accessing the exposed shells.
  • Use a pole to tap the branches, causing the almonds to fall.
  • Lay a tarp under the tree to catch the falling almonds for easy pickup.

Step 2: Drying the almonds

  • Remove the hulls from the nuts.
  • Spread the nuts while they are still in their shells in a thin layer on a drying surface. Leave them outside so the sun can dry them for you.
  • Use mesh to cover the almond kernels to protect them from birds and tarp to shield them from rain.
  • Check the drying progress by sampling a few nuts. Suppose the audible seeds within are hard; they are ready. On the contrary, if they are rubbery, they need more drying.
  • Once dried, bring the almonds indoors.

Step 3: Storing the almonds

  • Store the almonds indoors at room temperature.
  • Keep almond shells on to maintain freshness. They can last for up to 8 months.

Almond Tree Winter: How To Take Care Of Your Tree

As winter comes, almond trees enter a period of dormancy, requiring specific care to ensure their vitality when the warmer months return.

From mulching, frost protection to pruning, the following steps will safeguard the tree’s health.

Mulching for Insulation

Apply a layer of organic mulch, like coconut mulch, around the base of the tree, extending to the drip line. This helps insulate the soil, regulate temperature, and retain moisture during the winter months.

Frost Protection

Young almond trees are susceptible to frost damage. Consider warping the truck with burlap or using frost blankets to shield them from harsh winter winds.

For older trees, planting strategically or installing windbreaks can provide additional protection.

Nutrient Boost

Supply your trees with a slow-release fertilizer in late fall. This guarantees they receive essential nutrients even during dormancy.

Dormant Sprays For Disease Prevention

Apply dormant sprays to protect your almond tree from potential bacterial diseases.

Copper-based sprays are effective against bacterial and fungal infections that can thrive in winter conditions. Ensure thorough coverage, paying attention to both branches and the trunk.

Pruning for Air Circulation

Pruning your tree can reduce the risk of fungal infections by minimizing humidity around the tree. Remove any dead or crossing branches to enhance the overall structure.

This technique also helps you root a new almond tree. If you want to learn how to root a tree branch without cutting, here is the complete guide for you.

Winter wrap-up: Monitor your almond tree’s condition. Get rid of any snow buildup on branches to prevent breakage.
