Almond Tree Care
Almond trees are not just beautiful additions to your garden, but they also provide a delicious and nutritious nut crop.
Almond trees are among the earliest flowering stone fruit trees. They produce fragrant pink or white flowers in early spring before the leaves develop. Blooming so early in the season can also make almond trees susceptible to frost damage. The frost can harm the delicate buds and flowers, leading to a reduced number of nuts.
To minimize the risk of frost, I recommend planting apricot and other late-blooming trees alongside almond trees as they can help buffer the effects of frost.
Apart from this, to ensure your almond trees thrive and produce a plentiful harvest, it’s important to pay attention to their specific needs and provide the necessary care. Let’s look at some important factors in more detail:
Almond trees thrive in full sunlight, so choose a location in your garden that receives at least six hours of direct sunlight each day. This will help the trees develop strong branches and produce an abundance of nuts. If your garden doesn’t have an ideal spot, consider pruning nearby trees or structures that may cast shade on your almond trees.
When it comes to sunlight, it’s important to consider the changing seasons as well. While almond trees require ample sunlight during the growing season, they also benefit from some protection during the winter months. This can be achieved by planting them near a south-facing wall or using protective coverings to shield them from harsh winter winds.
Well-draining soil is vital for the successful growth of almond trees. Sandy loam or loamy soil with a pH level between 6 and 7 provides the best environment for these trees to thrive. Prior to planting, ensure the soil is adequately prepared by removing any weeds or rocks, and mix in organic matter for added nutrients.
Plus, it’s important to consider the soil’s texture and structure. Almond trees prefer soil that is loose and well-aerated, allowing the roots to penetrate easily.
If your soil is heavy clay or compacted, consider incorporating organic matter, such as compost or aged manure, to improve its structure and encourage good drainage.
Almond trees require regular and consistent watering, especially during the first few years of growth. Aim to provide 1-2 inches of water per week, evenly distributed. Deep watering is essential to encourage deep root growth and drought tolerance. However, avoid overwatering, as excessive moisture can lead to root rot.
When it comes to watering, it’s important to strike a balance. Too much water can suffocate the roots, while too little can cause stress and hinder growth.
Monitor the moisture levels in the soil and adjust your watering schedule accordingly. Mulching around the base of the tree can also help retain moisture and prevent weed growth. Mature trees are somewhat drought tolerant.
Temperature and Humidity
Almond trees prefer a Mediterranean climate, with moderate temperatures and low humidity. They are well-adapted to hot summers and mild winters. Ensure that your chosen location has good air circulation to prevent the development of fungal diseases.
While almond trees are generally resilient to temperature fluctuations, they can be susceptible to frost damage during the flowering stage. If you live in an area with late spring frosts, consider planting late-blooming varieties or providing protective coverings during cold nights to safeguard the blossoms.
Since the almond nut takes seven to eight months to mature, a lengthy growing season without frosts is crucial. The flowers of the almond tree, which are necessary for the crop, can be harmed by a spring frost. These factors account for why California is the main state in the United States where almond nut production takes place.
To promote healthy growth and nut production, it’s essential to provide your almond trees with proper nutrition. Before the growing season begins, apply a balanced fertilizer that is low in nitrogen and high in phosphorus and potassium. Follow the package instructions for application rates and timing. Additionally, periodically check the soil pH and adjust if necessary.
Keep in mind that over-fertilization can be detrimental to almond trees. Excessive nitrogen can lead to excessive vegetative growth at the expense of nut production. It’s important to strike a balance and provide the necessary nutrients without overstimulating the tree.
Consider conducting a soil test to determine the nutrient levels and make informed decisions about fertilization. This will help you tailor the fertilizer application to the specific needs of your almond trees, ensuring they receive the right balance of nutrients for optimal growth and nut production.
The most challenging aspect of growing almond trees for a crop of nuts is pollination. Cross-pollination between almond trees is essential for most varieties. In my observations, I’ve found almond trees are almost entirely dependent on pollinators like bees to transport pollen from one tree to another.
Honeybees and wild pollinators play a crucial role in ensuring a successful almond harvest by visiting around 90 to 100% of almond flowers per tree. If no bees visit the tree, the flowers will not develop into nuts.
Almond trees typically do not self-fertilize, unlike some other trees that produce edible fruit. This means for pollination, you will need two or more cultivars, and they can’t just be any cultivars, as flowering times must coincide.
Choosing a self-fertile variety is a wise move to make in order to avoid the need to plant various cultivars for pollination.
How to Harvest and Store Almonds from Almond Tree
Harvesting almonds from your almond tree is undoubtedly an exciting and rewarding experience. Harvesting almonds from your own tree can be a fulfilling experience that allows you to connect with nature and enjoy the fruits of your labor.
Follow these steps to ensure a successful harvest:
Regularly monitor the tree for signs of readiness. Mature almonds will change color from green to a golden brown. As the almond tree matures, it goes through a magical transformation. The once vibrant green almonds gradually turn into a luscious shade of golden brown.
This change in color indicates that the almonds are ripe and ready to be harvested. Take the time to observe your almond tree closely, appreciating the beauty of nature’s process.
I’ve found that the best time to harvest almonds is when the hulls begin to split open, usually starting with the nuts at the top of the tree.
Shake the Branches
Gently shake the branches to release ripe almonds. Alternatively, you can lay a tarp or sheet beneath the tree and give the branches a heavier shake to loosen the nuts.
Farmers usually use machines called shakers to encourage shelled almonds to drop off the ground, but we can do this manually.
When the time is right, it’s time to shake things up! Gently grasp the branches of the almond tree and give them a gentle shake. This motion helps to loosen the ripe almonds, allowing them to fall gracefully to the ground.
If you prefer a more efficient approach, you can lay a tarp or sheet beneath the tree and give the branches a heavier shake. The force will dislodge the nuts, ensuring a bountiful harvest.
Collect Fallen Almonds
After shaking, collect the almonds that have fallen onto the tarp or sheet. It’s important to harvest them promptly to prevent spoilage or attracting pests. The fallen almonds on the tarp or sheet are like precious gems waiting to be collected.
Take care to gather them promptly, ensuring that they are not left on the ground for too long. Almonds are susceptible to spoilage and can attract pests if left unattended. Treat each almond with care and respect, knowing that it will soon become a delicious treat.
Spread the collected almonds in a single layer on a clean, dry surface, and allow them to dry for a week. Stir them periodically to ensure even drying.
Once you have gathered your precious almonds, it’s time to prepare them for long-term storage. Lay them out in a single layer on a clean and dry surface, allowing them to bask in the warmth of the sun.
The drying process is crucial in preserving the quality and flavor of the almonds. Remember to give them a gentle stir every now and then, ensuring that each almond dries evenly.
Cracking and Storing
Once the almonds are fully dry, crack the shells and remove the kernels. Store the kernels in airtight containers in a cool, dry place to maintain freshness. The moment of truth has arrived! Your almonds are now fully dry and ready to be cracked open.
With a gentle hand and a sturdy nutcracker, carefully crack each almond shell, revealing the treasure within. Remove the kernels, which are the edible part of the almond, and marvel at their smooth texture and rich aroma.
To keep your almonds fresh and flavorful, store them in airtight containers in a cool and dry place, allowing you to enjoy their deliciousness for months to come.
How to Plant Almond Tree

Common Pests and Plant Diseases for Almond Tree
Almond trees, like any other plant, are susceptible to various pests and diseases. Here are some common issues to watch out for and preventive measures to take:
One of the most common pests for almond trees are aphids. These tiny insects can cause damage by sucking sap from the leaves.
Aphids, those minuscule creatures that seem to appear out of nowhere, can quickly infest almond trees if left unchecked. These pests have a voracious appetite for sap, which they extract from the leaves, weakening the tree in the process.
To combat aphids, it is crucial to be vigilant and promptly remove any affected foliage. Additionally, using insecticidal soap can be an effective way to keep these pesky insects at bay.
Another pest to keep an eye out for is the navel orangeworm. This pest attacks the nuts, leading to mold and reduced yields. Regular pruning and removal of infected nuts can help prevent infestations.
Spider mites, those nearly invisible creatures that seem to appear out of thin air, can also wreak havoc on almond trees. These tiny arachnids thrive in hot and dry conditions, making almond orchards an ideal habitat for them to multiply. As they feed on the leaves, they cause discoloration and weaken the overall health of the tree.
To deter spider mites, it is crucial to maintain proper watering practices, ensuring that the tree receives the right amount of moisture. Plus, periodically spraying the tree with water can create an unfavorable environment for these unwanted guests.
Leaf curl, a fungal disease that plagues almond trees, can cause significant damage if left untreated. The disease manifests itself through distorted and curled leaves, giving the tree an unhealthy appearance.
To prevent leaf curl, almond tree enthusiasts should apply fungicides during the dormant season, creating a protective barrier against the fungal spores. Additionally, practicing proper sanitation, such as removing fallen leaves and debris, can help minimize the risk of infection.
Brown rot, a common disease among almond trees, can also turn a promising harvest into a nightmare. This fungal infection affects the nuts, causing them to become shriveled and covered in mold.
To prevent the spread of brown rot, it is crucial to remove and destroy any infected fruit, preventing the disease from spreading to healthy nuts. Additionally, applying fungicides as a preventive measure can provide an extra layer of protection against this destructive disease.
Root rot, a disease caused by excess moisture and poorly draining soil, can spell disaster for almond trees. When the roots are constantly submerged in water, they become susceptible to fungal infections, leading to decay and, ultimately the death of the tree.
To prevent root rot, it is crucial to implement proper irrigation and drainage practices. Ensuring that the soil has adequate drainage and avoiding overwatering can go a long way in protecting almond trees from this deadly disease.
Now armed with the knowledge of how to plant, grow, and care for almond trees, you can embark on this rewarding gardening journey. With patience and dedication, you will soon enjoy the beautiful blossoms and abundant harvest of your very own almond tree oasis. Happy gardening!
