Almond Tree
Almonds can become large trees. Nurseries sell trees that have two parts: the roots, which are the part of the tree that grows underground, and the scion, which is the part of the tree that you can see above ground. The roots of a plant are selected for their hardiness, disease resistance, and sometimes to control the size of the plant. The primary reason for choosing a particular scion is the fruit quality it produces, though the ripening date and productivity are also important factors.
Almonds are not self-fruitful. Pollen must come from a different almond cultivar. Peaches may be a suitable pollen source for almonds. Although almonds generally flower before peaches, if the two blooming periods coincide, peaches can provide pollen for almonds. Insects are required for cross-pollination. Honeybees are the most common pollinator.
Almond kernels can be bitter or sweet. The bitter almond contains amygdalin, a substance that produces small amounts of hydrogen cyanide when it is chewed or crushed. Sweet almonds do not contain amygdalin. Almond shells can be hard or soft. There are hard-shelled almonds available from local stores near the winter holidays. You’ll need a tool to get into them. You can shell softshell almonds quite easily by hand. If the goal is to have almond kernels, paper-shelled almonds are the way to go because they are much more manageable.
Cultivar and Rootstock Selection
The United States Department of Agriculture has not conducted trials of almond cultivars in Washington County. But there are a few almond trees in backyards in the greater St. George area. Thus, some almond cultivars are surviving in St. George. A nurseries rating of hardiness to USDA zone 5 indicates that the cultivar can survive the average minimum temperature of −20 °F (−28.9 °C) that is experienced in zone 5. These robust almonds are actually hybrids of peaches and almonds with thick hard shells and slightly bitter kernels. Although there hasn’t been any scientific evidence to back it up, people have claimed that almonds from California would be able to survive in St. George.
Almonds are commonly propagated using peach seedlings as rootstocks. Peaches are hardy in the St. George area. This means that any peach rootstock would be suitable for planting in the area.
The following cultivars, listed in alphabetical order, may work well in Utah.
All-in-one
This is a paper-shelled cultivar that is more tolerant to cold than others, as it is advertised to be hardy in USDA hardiness zone 5. It has a paper shell and a sweet kernel and is reported to be self-fruitful and smaller than average.
Hall’s Hardy Almond
This is actually a peach almond hybrid. Although the tree can survive the winter in Cache Valley, the nuts have a very hard shell and the kernels are bitter. The showy flowers are beautiful in the spring. It is not recommended for nut kernel production.
Mission
Also known as ‘Texas’, this variety is harvested 40-60 days after Nonpareil. It has a strong flavor, can’t be blanched (blanching softens the skin on the outside of the kernel so it can be removed), and has a hard shell with good integrity and no opening around the shell.
Nonpareil
This is a premier cultivar in California. It takes approximately three weeks for the bloom to appear in California’s central valley and the plant matures at the end of August. The kernel is a flat, medium-large sized nut with excellent quality and flavor. It has become the basis of the almond industry. Shell is paper thin, often poorly sealed. The tree is large and easily harvested.
Ne Plus
This older California cultivar flowers between Nonpareil and Mission. This text is discussing the physical characteristics of a crop. The crop has plump, elongated kernels that are often coated with candy glazing for marketing purposes. Each nut has the potential to produce two kernels.
Site Preparation
The site should be selected and prepared before planting. Choose a spot for your garden that gets sunlight for most of the day. The planting is on a gentle slope with a lower area next to it. This allows cold air to flow away from the planting on cold nights. An adult almond tree can grow to be about 20 feet wide and 20 feet tall, with a 10-12 foot radius around the trunk. Before planting, control perennial weeds around the planting location. Incorporate organic material into the planting location. Organic matter can come from compost, peat moss, potting soil, or manure. Work the amendment into the first 8 inches of the soil. Almonds will not grow well in wet soils, so it is important to make sure the soil is well-drained.
Planting Almonds
Almonds should be planted when the ground has thawed and the trees are still dormant. They are able to do this because the ground isn’t frozen. This allows them to put down deeper roots before the next winter. Try to find a place in your yard that gets a lot of sun and is also protected from cold winds. If you want to harvest a lot of almonds, then you’ll need to plant at least two of them. This is because they require cross-pollination in order to produce. You can plant any almond variety. You should plant almond trees at least 15 feet apart to give them enough room to grow.
Although this tree can technically live indoors, it is much less likely to produce fruit if it is kept indoors. You will need a dwarf almond tree and a 10-20 gallon container with drainage holes that’s easy to move if you decide to make this trade-off. You should put younger trees in a 10-gallon Air Pot. The container plant will do best if you move it outside during the summer and bring it in when the weather gets cold.
You need one almond to plant. You can get it from a nursery or grow your own from a seed. The plant should be at least 6 inches tall before you start planting it. Carefully take the baby almond tree out of its pot, moisten the roots, and loosen them up. Be careful not to damage the taproot, as its health is key to the rest of the tree.
Make a hole that is as large as the entire root system of the plant so that it has enough room to grow. Fill the hole around the tree with the backfill, pressing it down gently. You should give your almond tree a lot of water to help it grow.
New almond trees grow at their own pace. It can take a couple of years up to twelve years for an almond tree to produce almonds. Please be patient as it may seem like an unbearably long time. These bountiful trees are well worth the wait.
Care
As we mentioned, the amount of almonds an almond tree produces depends on the amount of care it receives. The following offers tips on how to get the most from an almond orchard.
Sun and Temperature
Almond trees like their surroundings sunny, hot and dry. If they get more sun, their fruitset will improve. To achieve the best possible results, ensure that your tree has access to at least eight hours of full sunlight each day. Although they can grow in partial shade, these trees will produce more flowers and fruit when they are in full sun.
The ideal fruiting temperature is 60-85°F, but the length of the growing season will directly affect fruiting. If your tree only gets a short warm season, it may not produce fruit. Frost can have a severe impact on fruit production and can destroy early flowers in the spring. In addition to watering this tree, you will need to protect it from colder winds.
To bear fruit, almond trees must go through a period of dormancy, which means they are exposed to cold temperatures for an extended period of time (but not too cold!). They need about 200-300 hours of temperatures below 45°F. The trees will lose their leaves and store up energy to produce almond fruit. Dormancy takes place from November to January.
If you live in zones 7-9, you can keep your almond tree outside all year long, and it will get the cold weather it needs. Some types of almond trees can also tolerate the climate in zones 5 and 6, but it is advisable to do some research beforehand. If you have an indoor-outdoor tree, you’ll have to find a cool place for it that is protected from frost, such as a garage or shed. The harvest may not be as good as it could be if the conditions were different.
Watering & Humidity
Watering is a key part of getting your tree to produce nuts, especially almonds which are known to be heavy water drinkers. Young trees will die if they do not receive 2-3 inches of water every day, while mature trees can survive on the same amount of water every week. Not only do they need extra water in the spring to boost flowering, but they also need extra water during the summer to help the flower buds mature. They should get more than the recommended amount of vitamins during summer and fall. You should stop watering your plants a week or two before you harvest them so the fruit can dry out.
To produce a lot of almonds, a lot of water is needed, but too much water can damage the tree. To maintain the correct balance, you need to be consistent. Water deeply, but don’t drown the roots. Wait until the top inch of soil is almost dry before watering again.
Almond trees cannot grow in high humidity environments, which is why they are not found in the tropics. The drier your location is, the better.
Soil
Almond trees need specific conditions in terms of sun and water, but they can adapt to various types of soil. The only criterion that is absolutely necessary is that the soil drains well. The roots can rot if it stores too much moisture. If your soil needs better drainage, you can improve it by adding sand or organic matter.
If you want the best results, choose sandy or loamy soil that is fertile and has a pH of around 6.5. Almond trees are especially susceptible to diseases like verticillium wilt that occur in the soil. For container plants, always use new, store-bought soil. If you think there might be a disease in your garden’s soil, do a soil pathogen test to figure out what to do next. These are often provided by university agriculture departments.
Fertilizing
Almond trees need to be fertilized regularly to stay healthy – so be prepared to stay on top of their fertilizing schedule! The plants need a lot of nitrogen to grow and produce completely. However, if nitrogen levels are too high, it can cause problems for the trunk and leaves. You will need to find a good balance in your fertilizing schedule.
One way to determine how much fertilizer to apply to a tree is to use the following method: apply one ounce of granular or slow-release fertilizer per year the tree has been growing. Once the tree is mature, use the manufacturer’s recommended amount of fertilizer. You should start fertilizing your plants in the early spring, and then continue doing it every 4-6 weeks until you harvest them. Give a dose of the pesticide after the leaves are harvested and before they fall off. This will help the tree bloom the next year.
Do not apply any fertilizer to baby trees until the spring after they have been planted. Start with a small amount of fertilizer for the first application. Fertilizing regularly and in small amounts reduces the likelihood of nitrogen burns. The fertilizer you use should contain high levels of nitrogen and phosphorus. However, a balanced one works fine as well.
Pruning
Trimming your almond tree is crucial to preserving its health and productivity. The young tree’s shape will be determined by how it is trimmed, which in turn will determine how it produces. During the winter months when the almond tree is not growing, prune it back to 3-5 branches which will give it a cup or vase shape. Use clean loppers or pruning shears as needed.
Mature plants should have about 20% pruned each year. You should focus on maintaining the shape of the tree, since new wood will fruit better. If the canopy is too dense, thin it out so that air can circulate and sunlight can reach the center. This will help the tree grow new flowers and be more vigorous. Pruning dead or dying branches any time of year is important.
Almond trees can also be pruned into a fan-shaped espalier.
Propagation
To maintain the purity of the species and improve its longevity, almond trees are often propagated through grafting. This is a method of grafting that is simple and easy for you to do by yourself. To start, you’ll need the following:
- An almond tree to take a bud from
- A healthy rootstock (preferably a peach tree or bitter almond)
- A sharp, clean knife
- Grafting tape
We will start by picking a healthy bud from an almond tree. Use your knife to cut the bud off the branch, about an inch above and below it. Cut through the bark and slightly into the surface of the trunk. Set aside the bud for now.
Move over to the rootstock. A different, hardier variety of almonds would also work well for almond grafts. Cut a healthy-looking section from the rootstock that’s a little bit longer than your bud cutting. Cut through the bark, but not the wood underneath. In addition to the cut you just made, make another cut horizontally to form a T shape. Now you can cut the bark back gently along the line you just made.
Cut a small section of the bark on the rootstock and slide your bud cutting under it. It should fit in like a nice little pocket. Using grafting tape, secure the bud in place. The only thing left to do now is wait for the bud to merge with the rootstock. Remove the tape when it is no longer sticky.
If you do not want to graft your almond, you can propagate it the old-fashioned way–by seed. The tree that results from cross-pollination may be different from the parent tree. You’ll need an almond that is fresh and has not been roasted or changed in any way.
Place raw, fresh almonds in a bowl of water. Soak for 48 hours. When the time is finished, take it out of the oven and put it on a damp paper towel. To store the towel and seed for about a month, put them in a plastic bag and keep them in the fridge. After the seed has been in the ground for a while, it will sprout and begin to grow.
Select a spot for your plant that has well-drained soil. watering the plant regularly will help it to grow, but too much water can damage it. Place the plant in the sun and wait for the sprout to grow. When the plant has reached a height of six inches, it can be transplanted into its permanent pot.
