Almond Tree

The almond tree is a deciduous tree in the family Rosaceae which is grown for its edible seeds (nuts). The almond is a species of tree native to Iran and surrounding countries, including the Levant. The botanical name of almond is Prunus dulcis. Prunus dulcis is an economically important crop tree grown primarily in Mediterranean climates between 28° and 48° N and between 20° and 40° S, California producing nearly 80 percent of the world’s supply. Almond is a stone fruit (drupe) and consists of three layers, the outer exocarp, the middle fleshy mesocarp, and the inner endocarp.

The tree has brown or gray bark and either an erect or weeping growth habit depending on the variety. Almond leaves are long with a serrated edge and grow alternately on the branches. The tree produces white to pale pink flowers and hairy green fruits which are oblong in shape. The fruit is a drupe, containing a single seed. The seed is protected by a hard brown shell. At maturity, the flesh of the fruit becomes leathery and splits to reveal the nut inside. Nuts generally measure 3.5 to 6 cm (1.4–2.4 in) in length. Almond trees have a commercial lifespan of between 30 and 40 years.

Growth Nutrition of Almond Tree

The nutrients most likely to be needed in post-harvest fertiliser programs for almonds are nitrogen (N), phosphorus (P), potassium (K), zinc (Zn) and boron (B).

Nitrogen is one of the most required nutrients in almonds. It is important to build the tree canopy and encourage vegetative growth, leading to improved bud formation, higher yields, and higher nut protein contents. Optimum tree nutrition is essential for achieving top nut yields. Potassium is particularly important and needed in large quantities for nut-fill and highest yields.

Types of Almond Tree

There are two varieties: sweet almond (P. dulcis, variety dulcis) and bitter almond (P. dulcis, variety amara). Sweet almonds are the familiar edible type consumed as nuts and used in cooking or as a source of almond oil or almond meal. The oil of bitter almonds is used in the manufacture of flavouring extracts for foods and liqueurs, though prussic acid must first be removed.

California Paper Shell Almond

California Paper Shell Almond is known to produce medium to large-sized, flattish nuts with paper-like shells. This tree originated in California in the 1880s. It produces consistently prolific crops of medium-sized kernels. This tree is relatively easy to prune and train. You can pollinate it with Carmel, Price, Ne Plus Ultra, and other California Paper Shell Almond Trees as well.

Livingston Almond

Livingston Almond produces medium-sized, well-sealed kernels with a paper-thin shell. This tree blooms about five days after Nonpareil with varieties such as Padre and Butte. It also matures about ten days after Nonpareil, much earlier than Padre and Butte. Livingston Almond is a medium to large tree with an upright habitat and prolific yearly yield.

Mission Almond

Mission Almond is a late-blooming, prolific tree. It produces short, plump kernels with exceptionally hard shells. This tree requires cross-pollination as it is not self-fertile. You can cross-pollinate it with other Almond varieties, such as Price, Carmel, All-In-One, and Nonpareil. It thrives in full sun and clay, loamy, and sandy soils.

Mono Almond

Mono Almond is a prolific tree and a relatively good pollinator. It produces almonds with hard shells and sweet-tasting kernels. Mono Almond is a disease-hardy tree and a vigorous grower. This tree grows exceptionally well and yields healthy, flavorful crops in sun-kissed locations in a wide variety of free-draining soils.

Padre Almond

Similar to the Butte variety, Padre Almond produces late blooms and crops; it blooms five days after Nonpareil and matures for harvest about 23 days after Nonpareil. Padre Almond is an upright tree that produces almonds with hard, nicely sealed shells and medium to small kernels. This is a prolific tree that thrives in sunlit areas and well-drained soils.

Ruby Almond

Ruby Almond blooms about eight days after Nonpareil. It also offers a late harvest of crops that ripen about 31 days after Nonpareil almonds. It yields medium to small-sized, plump kernels that grow in nicely sealed, semi-hard shells. Ruby Almond is a productive, moderately vigorous tree with an upright growth habitat.

Thompson Almond

Thompson Almond is highly susceptible to non-infectious bud failure, peach twig borer, and navel orange worm.

Ripon Almond

Ripon Almond blooms quite late into the season. It flowers more than eight days after Nonpareil Almond. For successful cross-pollination, you can plant your Ripon near Fritz and Ruby Almond. Unlike many Almond Trees, Ripon Almond isn’t compatible with Ne Plus Ultra. It’s typically ready for harvest around 15 to 20 days after Nonpareil Almond Trees.

Planada Almond

Planada Almond trees bloom around 8eightdays after the popular Nonpareil Almond Trees. Since they bloom so late, they are also not prepared for harvesting early. You can harvest these trees around 40 to 60 days after the harvest time of Nonpareil Almond Trees. For prolific crops, plant your Planada Almond in a sunlit area in free-draining soil.

Carmel Almond

Carmel Almond is an exceptional pollinizer for Nonpareil Almond Trees. It produces high-quality kernels that are sealed properly in hard shells. Young Carmel Almond Trees produce heavy crops. Their harvest time is two to three weeks after the harvest time of Nonpareil Trees. Carmel Almond Trees are not self-fertile and need prolific pollinators to yield abundant crops.

Ne Plus Ultra Almond

Ne Plus Ultra Almond is a French variety loved commercially because of its fast-growing habitat and large, light brown almonds with flat, long, sweet kernels.

Maxima Almond is an excellent pollinator for Nonpareil, Carmel, Wood Colony, Mira, and Monterey Almond Trees.

Makako Almond

Makako Almond Tree is an extra-late flowering Almond Tree cultivar. This tree blooms around 20 to 21 days after Nonpareil Almond Trees. The best part about Makako Almond is that it can produce prolific crops under passive self-pollination. This is a vigorous tree with a balanced habitat. It produces large kernels that are enclosed in hard shells.

Planting Almond Tree

  1. Choose a sunny site. Almond trees need ample room to grow because they can grow up to 30 feet in height. Plant your sapling 15 to 20 feet away from buildings, power lines, and other trees. Almond trees need full sun and well-draining loam soil to thrive.

  2. Prep your sapling. Setting up your almond tree for success starts before it's even in the ground. Using a garden hose, spray off the sapling's rootball to make sure it's hydrated and that the roots make good contact with the soil.

  3. Dig your hole. Dig a hole deep enough to accommodate your plant's root system. If you've bought a bare-root or container-grown tree, dig your hole deep enough to match the depth at which your tree was planted in the nursery—most likely 18 to 24 inches. To make sure your hole is deep enough, gently place the plant inside and rest the taproot firmly against the bottom. If the base remains above the top of the hole, don't force it deeper. The taproot is sensitive and easily damaged by aggressive handling or trimming.

  4. Plant your tree. Place your sapling in the center of the hole and backfill it with well-draining soil. Firmly tamp down the soil to remove any excess air while filling. Immediately water your sapling with at least one gallon of water. Place a layer of mulch around the base of the tree to help retain soil moisture.

  5. Prune small twigs. Trim off any small twigs near the base of the tree. Young trees need pruning in order to focus all of their growth on their trunk and branches.

  6. Exercise patience. The almond tree's dormant period lasts about 5 years from seedling to fruiting, so don’t be alarmed if nuts don’t appear on your tree for the first few years.

Care for Almond Tree


Your almond tree will bear the most flowers (and therefore, potentially nuts) if located in full sun.


Good drainage is important, so sandy soils are preferred over clay soils. Till deeply into the soil so that the roots can strike down deep.


Like other nut trees, almond trees need a lot of water to grow healthy. Aim for about 3 to 4 inches of water per week, or enough to keep the soil moist. Almond trees are relatively drought tolerant, but it's best to provide plenty of water to produce a suitable harvest. Just remember that overwatering your tree can cause root rot: Soggy soil means the plant is receiving too much water.


Fertilize your almond tree in spring with a balanced fertilizer. Apply this fertilizer along the drip line of the tree.

Growing and Harvesting a Crop of Almond Nuts

Technically, the crop produced by almond trees is not a nut, but a stone fruit (drupe). The fruit growing on almond trees initially looks nothing like the almond you later end up eating: Instead, what you see is a leathery, green hull. Inside the hull is a hard, light-colored shell. This is the shell that we crack with a nutcracker to get to the edible part. Cracking the shell frees the brown seed ("nut") that we eat. While you can eat the fruit of an almond tree, it's best before the nuts are hardened, which may be too early to let them ripen fully.

There are different types of almonds. The kind found in nut bowls and dessert recipes is the sweet almond (Prunus dulcis), but there is also a bitter almond (Prunus dulcis var. amara) that is used, for example, to flavor certain liqueurs.

For the most part, almond trees are not self-fertile, as are some trees that bear edible fruit: You will need two or more cultivars for pollination, and they can't be just any cultivars (flowering times have to line up). This is the trickiest part of growing almond trees for a crop of nuts. Plant your almond trees 15 to 25 feet apart from one another.

A smart way to avoid having to plant different cultivars for pollination purposes is to select a self-fertile variety. For example, 'Garden Prince' is a self-pollinating almond tree that grows 10 to 12 feet tall; however, it is cold-hardy only to zone 8.

Almonds give you a clue as to when they are ready to be harvested: The hulls begin to split apart, revealing the familiar, light-colored shell. Do not wait too long after this splitting to harvest your almond nuts because the exposed shell is now fair game to both birds and insects.

The easiest way to get the almonds off the tree for the home grower is to tap the branches with a pole. Lay a tarp down ahead of time to catch the almonds as they fall to make pick-up easier.

After gathering the almonds, they must be dried properly, or else they can become moldy. Drying requires several steps:

  • Remove the hulls.

  • Spread the nuts out (with the shells still on), in a thin layer, across a surface conducive to drying. An ideal surface would be a table, the top of which has been replaced by a screen. Cover them with BirdBlock mesh (buy on Amazon) to prevent the birds from taking them, and cover them with a tarp when rain is expected.

  • The only way to know for sure when the drying process is complete is to sample the "nuts." Crack the shells of a few to find out whether the edible seeds within are hard or rubbery. If they are rubbery, then they are not completely dried out yet. If they are hard, then they are ready.

  • When you have determined that your crop has dried out enough, bring the rest of the nuts, with their shells still on, indoors. Stored at room temperature, they will keep for eight months.

Pruning and Propagating Almond Trees


Pruning has different purposes at different stages of the tree’s life.

Pruning young almond trees determines their future shape, and therefore their productivity and the quality of the nuts produced. It’s important to get it right to ensure a good harvest.

Almonds are commonly pruned into a “vase” type shape with 3-4 main branches, which also allows for ease of harvesting. If done correctly, the “vase” shape makes the tree more vigorous, more productive, and guarantees a longer lifespan.

Pruning after maturity, however, is more about maintaining the shape established in the early stages of the tree’s life. Pruning renews the tree and stimulates it to produce more. Around 20% of an older tree’s canopy should be pruned back each year.

Propagating Almond Trees

By Root Graft

Like most fruit and nut trees, almonds are normally propagated by budding. This is by far the easiest and most effective way to grow them and ensure that they grow true to their parent plant.

A hardy root stock (often of peach or the more resilient bitter almond variety) is used to give the tree resistance to soil-borne diseases, and then the fruit-bearing branch is grafted onto the root stock.

Using grafted almonds makes the trees much more resilient, and they often grow much faster than from seed. This is particularly the case for those that have a peach root stock, which generally tends to be more productive than those grafted with almond root stock.

A further complication with almond trees is that you have to have at least two different, but compatible, varieties so that they can cross pollinate, usually via bees.

From the Nut

It’s perfectly acceptable to try growing your own from seed for a backyard project, as long as you are aware that it will take much longer to bear fruit, and any nuts that are produced may not be of the same quality as that of the parent plants.

Find fresh nuts – not roasted like you find in the supermarkets. Leave them to soak for around 48 hours, and then place them on a wet paper towel in a plastic bag and place them in the refrigerator.

About 3-4 weeks in the refrigerator should do the trick, and the almonds should start sprouting. At this point, they’re ready to pot in a nice, well-drained soil mix (something like a mix of sand and compost) and placed in direct sunlight, ideally on a windowsill where it’s nice and warm.

The important thing is to keep them moist, but never soggy. After they have reached about 6 inches in height, they’re ready to be moved up to a bigger pot size.

Benefits of Almond Tree

Almonds are said to be beneficial for your health, but in what ways is the question that you need to ask yourself. So, what are the health benefits of almonds and what good would this nut do if it is added to your daily diet? Well, here are some scientifically proven benefits of almonds and their usages.

Almonds Reduce Cholesterol:

According to a recent study by the American Dietetic Association, consuming almonds were proven to increase your levels of Vitamin E in your red blood cells and also reduces your risks of having cholesterol. By boosting the levels of vitamin E in your bloodstream antioxidants are formed that prevents your cells from clogging developing cholesterol. Thus consuming a handful of almonds daily can generate more vitamin E into your bloodstream and this can also save you from the risk of developing cholesterol.

Almonds are Good for Your Heart:

When almonds are consumed along with some other nuts, it is said that it is good for your heart. Well, according to a study published in 2014, researchers found that samples in the study who consumed almonds has more antioxidants in their bloodstream and this helped in reducing blood pressure and improved the flow of blood to various parts of the body. Also, the research concluded by stating that Mediterranean diets that had a lot of nuts in their foods had more health benefits.

Almonds Regulate Blood Sugar:

Consuming almonds is said to regulate blood sugar levels and stabilize them. This is because almonds have magnesium in them and it advised that you consume a handful of almonds daily. However, for people suffering from type 2 diabetes, almonds play an integral role in stabilizing it. So what basically happens if a diabetic person consumes almonds? The answer is, the person would develop insulin resistance which is great for people suffering from diabetes and this is because of the content of magnesium in the nut.

Almonds can help control Blood pressure levels:

Low magnesium levels can cause high blood pressure. This leads to heart attacks, strokes and kidney failure. Almonds contain magnesium which helps control blood pressure effectively. If your body lacks magnesium, you must add almonds to your diet.

Almonds have High Vitamin E:
