Almond trees (Prunus dulcis) are deciduous trees widely cultivated for their nutritious nuts. They are native to the Middle East and Central Asia but are now grown in many other places in the world, including the United States.
In the US, California is the largest producer of almonds, accounting for more than 80% of the global almond supply. Almond trees are well-suited to the climate and soils of California’s Central Valley, which has hot, dry summers and mild winters. Other states that produce almonds in smaller quantities include Arizona, Texas, and Georgia.
Growing Season
Almond trees require a long, hot growing season with temperatures between 15°C and 30°C and well-drained soils. They are generally planted in the fall or winter and begin to produce fruit after two to three years. The trees require pollination, which is typically done using honeybees.
Almond trees typically reach maturity and start producing nuts between 3 and 5 years after planting, although this can vary depending on the growing conditions and the specific variety of almond trees.
Growth Stages
The growth of an almond tree can be broken down into a few stages:
Dormant season: During winter, almond trees are dormant and do not actively grow. This is the best time to plant new trees or prune existing trees.
Bud break: As the weather warms up in the spring, almond trees grow again. The buds on the branches swell and eventually break open, revealing new leaves and flowers.
Flowering and pollination are essential for the development of almond trees. In the spring, almond trees produce beautiful pink and white flowers that attract bees and other insects to help with pollination. After successful pollination, almonds develop in size throughout the summer months until they reach maturity in late summer or early fall when they split open on the tree, ready for harvest.
In addition to their use as food, almond trees are also valued for their ornamental qualities. Almond trees are often grown in home gardens and parks for their attractive flowers and foliage.
Pollinators
It is important to have a healthy population of bee species around an almond tree as these will be responsible for most of its pollination needs.
It is recommended that gardeners practice integrated pest management techniques such as planting companion plants near their almonds. These plants can act as natural repellents against pests while providing food sources attractive to beneficial insects like bees which help produce better yields from their crop through increased flower visits by these helpful bugs during the flowering season.
Weeding
Finally, hand-weeding should also be done regularly between rows so weeds don’t compete with young saplings during the establishment stage, reducing chances of poor yield due lack of competition resources needed by small seedlings at this stage.
Buying a tree
Almond trees are typically sold as bare-root or container-grown trees. Bare-root trees are less expensive and can be planted when dormant in the winter, while container-grown trees planted any time of year but may be more expensive. When choosing a tree, look for one with a healthy root system and a straight, sturdy trunk.

Planting your tree
Once you have chosen and purchased an almond tree, it is essential to plant it correctly. Lower the root ball to the same depth as in its container or nursery bed. If planting a bare-root tree, soak the roots for several hours before planting. Place plenty of soil around the base of your new almond tree and water thoroughly after planting.
Watering and fertilizing
Almond trees require regular watering, especially during the growing season. Water deeply once or twice a week, depends on the weather and soil conditions. Fertilize the tree in the spring and summer with a balanced fertilizer. Follow the manufacturer’s instructions for application rates.
Applying organic fertilizers helps create healthier soil conditions allowing more nutrients available for plant growth and promoting larger fruit sets.
Pruning
Prune almond trees in late winter or early spring before new growth appears. Remove dead, diseased, or damaged wood and thin out crowded branches for good air circulation and light penetration. Be sure to prune lightly, as almond trees can be sensitive to heavy pruning.
Harvesting
Almond trees produce a fruit with a hard, woody shell that contains the edible almond nut. The nuts are harvested in the fall after the shells have dried, split open, and processed for consumption. Almonds are highly nutritious and rich in protein, healthy fats, fiber, vitamins, and minerals.
Almonds are ready for harvest in the late summer or early fall, depending on the variety and climate. Look for almonds that have split open on the tree and are slightly brown in color. Shake the tree gently to release the almonds, or use a mechanical shaker. Store almonds in a cool, dry place for up to a year.
Caring for your Tree:
Almond trees require regular care throughout their life cycle to produce healthy fruit yearly
water regularly during dry periods
prune away dead wood and damaged branches annually
fertilize with nitrogen twice a year (in early spring before bud break and again mid-summer)
control pests such as aphids by spraying insecticidal soap solution every two weeks until they are gone
protect young trees from frost damage by wrapping them in burlap or other material
mulch around newly planted trees with straw or bark chips
harvest almonds when they turn brown on their stems but still feel slightly firm when squeezed gently between thumb & forefinger
