How To Grow Almond and Its Benefits

How to grow almond will be covered in this post, but first, what is almond? Almonds (Prunus dulcis) are a fascinating and valuable crop in the world of agriculture, renowned for their distinctive characteristics and significant economic importance. Almond trees belong to the Rosaceae family, making them relatives of other fruit-bearing trees like peaches, plums, and cherries. They are deciduous trees, which means they shed their leaves seasonally. Almond trees typically reach a height of 13 to 33 feet (4 to 10 meters) and exhibit a somewhat spreading growth habit.

The leaves of almond trees are elongated and serrated at the edges. They are lanceolate in shape, with a deep green color, and are arranged alternately along the branches. These leaves play a vital role in the photosynthesis process, contributing to the tree’s overall health and nut production. Almond trees produce exquisite, fragrant flowers that are a sight to behold in late winter or early spring, depending on the climate. These flowers are characterized by five petals and a distinctive pink or white coloration.

Almond blossoms are often among the first signs of spring, making them a crucial component of early pollinator habitats. The fruit of almond trees is technically a drupe, consisting of an outer hull, a hard shell, and the edible almond seed within. Almonds themselves are seeds, not true nuts, and they have a unique kidney-like shape. When mature, the hull splits open, revealing the hard shell that protects the almond kernel.

There are various almond varieties cultivated globally, each with its own unique characteristics, including size, flavor, and shell hardness. Prominent almond varieties include Nonpareil, Carmel, Sonora, and Butte. Nonpareil, known for its smooth, thin shell and excellent kernel quality, is one of the most widely grown and recognized almond varieties.

How to Grow Almond

Growing almonds can be a rewarding endeavor, but it requires careful attention to various factors to ensure a successful crop. Here, I’ll provide you with a comprehensive guide on how to grow almonds in an agricultural setting:

1. Selecting the Right Location: Almonds thrive in regions with a Mediterranean climate, characterized by mild, wet winters and hot, dry summers. They require a minimum of 300 to 400 chill hours (hours below 45°F or 7°C) during the winter for proper bud development. It prefers well-drained soils with a pH level between 6.0 and 7.5. Ensure that the soil is deep and free from compaction to allow for healthy root development.

2. Choosing Almond Varieties: Select almond varieties that are well-suited to your climate and intended use. Popular almond cultivars include Nonpareil, Carmel, and Butte, each with its own unique characteristics, such as kernel quality and shell hardness.

3. Planting Almond Trees: Almond trees are typically planted during the dormant season, which is in late winter or early spring before the buds break. This allows the tree to establish roots before the growing season. Plant almond trees with sufficient spacing to accommodate their mature size.

Standard spacing is often around 18 to 22 feet (5.5 to 6.7 meters) between trees in rows and 20 to 24 feet (6.1 to 7.3 meters) between rows. Ensure that the tree is planted at the same depth as it was in the nursery. Avoid burying the graft union, which should remain above the soil line.

4. Irrigation: Almond trees benefit from efficient drip irrigation systems that deliver water directly to the root zone. Proper moisture management is crucial, especially during the growing season.

Young almond trees require more frequent watering, gradually transitioning to deeper, less frequent irrigation as they mature. Adequate moisture during the nut filling and hull split stages is critical for nut development.

5. Fertilization: Conduct soil tests to determine nutrient deficiencies and tailor your fertilization program accordingly. Nitrogen, phosphorus, potassium, and micronutrients are essential for almond tree health and productivity.

6. Pruning and Training: Regular pruning and training are essential to shaping the tree, promoting air circulation, and facilitating sunlight penetration. This helps prevent disease and ensure even nut development. Pruning is typically done during the dormant season.

7. Pest and Disease Management: Implement integrated pest management (IPM) strategies to monitor and control pests and diseases. Common almond pests include aphids, mites, and navel orangeworm, while diseases like brown rot and shot hole can affect almond trees.

8. Harvesting: Almonds are ready for harvest when the hulls split open, revealing the mature nuts inside. Mechanical shakers are often used to shake the almonds from the tree, after which they are collected and processed. Harvesting usually occurs in late summer or early autumn.

9. Post-Harvest Handling: Proper post-harvest handling is crucial to maintaining almond quality. After harvesting, almonds are dried to a moisture content of about 6%, hulled to remove the outer shell, and then sorted and packaged for sale or processing.
