Depending on the variety, altitude and weather, flowers may open as early as late winter. They appear before or as the leaves begin to develop.<\/p>\n<p>This early blossom makes the tree especially striking in the landscape, but it also exposes it to late frosts. A sudden drop in temperature can damage flowers or young fruit and reduce the harvest.<\/p>\n<\/section>\n<section id=\"pollination\">\n<p class=\"rkdca-eyebrow\">Flowers and the living world<\/p>\n<h2>How do flowers become almonds?<\/h2>\n<p>For fruit to form, pollen must reach the stigma of a compatible flower. In almond trees, this transfer is mainly carried out by visiting insects, especially bees, as they move from flower to flower in search of nectar and pollen.<\/p>\n<p>Not all varieties behave in the same way. Some are self-fertile, while others require pollen from a compatible variety flowering at the same time. Weather also plays an essential role: cold, rain or wind can reduce insect activity even during abundant flowering.<\/p>\n<aside class=\"rkdca-comparison-note\">\n<p class=\"rkdca-eyebrow\">Do not confuse<\/p>\n<p>A spectacular display of blossom does not guarantee a large harvest. Pollination, fertilisation, temperature and water availability all influence fruit set and whether young fruits remain on the tree.<\/p>\n<\/aside>\n<\/section>\n<section id=\"branch-to-fruit\" class=\"rkdca-fruit-cycle\">\n<div class=\"rkdca-fruit-cycle__intro\">\n<p class=\"rkdca-eyebrow\">From fruit to almond<\/p>\n<h2>How does the hull protect the almond?<\/h2>\n<p>After fertilisation, the flower\u2019s ovary gradually develops into fruit.

Their ancient domestication resulted from the gradual selection of trees producing sweet seeds, unlike the often bitter seeds of wild forms.<\/p>\n<p>Through trade, migration and farming practices, the almond tree spread around the Mediterranean. In dry regions, its cultivation remains closely linked to variety choice, soil, relief, available water and frost risk.<\/p>\n<\/section>\n<figure class=\"rkdca-figure rkdca-figure--landscape\"><img loading=\"lazy\" decoding=\"async\" class=\"attachment-large size-large\" src=\"https:\/\/chevalier-de-lastree.com\/wp-content\/uploads\/2026\/08\/terres-aragon-paysage-4-1024x473.jpg\" alt=\"Tree-covered landscape at Les Terres d\u2019Aragon\" width=\"1024\" height=\"473\" \/><figcaption>Cultivated trees, spontaneous vegetation and relief form a single landscape.<\/figcaption><\/figure>\n<section id=\"aragon\">\n<p class=\"rkdca-eyebrow\">The landscape we observe<\/p>\n<h2>What place does the almond tree hold in these landscapes?<\/h2>\n<p>The photographs gathered in this notebook come from the estate and its surroundings, across a geographical area extending from <strong>Valderrobres<\/strong> and <strong>Beceite<\/strong> to the <strong>Ebro Delta<\/strong>.

There is no single date that applies everywhere.<\/p>\n<\/details>\n<details>\n<summary>Does the almond tree need pollinating insects?<\/summary>\n<p>Many varieties benefit greatly from visits by bees and other insects. Some varieties are self-fertile, but pollinators generally remain helpful to fruit set.<\/p>\n<\/details>\n<details>\n<summary>Why are late frosts dangerous?<\/summary>\n<p>Flowers and young fruit are sensitive to cold. A frost after the flowers have opened can reduce fruiting, sometimes severely.<\/p>\n<\/details>\n<details>\n<summary>Can a bitter almond be recognised by appearance?<\/summary>\n<p>Not reliably. A very bitter almond may look like the others and occur within the same harvest. The bitterness may be linked to a higher level of amygdalin, a naturally occurring compound that can release cyanide during digestion. An almond that tastes unusually bitter should be spat out and not swallowed. Systematic tasting is not a safe sorting method.<\/p>\n<\/details>\n<details>\n<summary>Is sweet almond oil always edible?<\/summary>\n<p>No. Cosmetic oil should not be consumed. For cooking, choose an oil explicitly sold as a food product.<\/p>\n<\/details>\n<details>\n<summary>Why will this notebook be expanded?<\/summary>\n<p>Because it connects general knowledge with real observations from Les Terres d\u2019Aragon.
