Almond tree - How to pollinate the almond tree?
Quick Read / The Essentials of Almond Pollination
Pollination is a crucial step in almond cultivation, directly determining the yield and quality of harvested almonds. Most varieties are self-incompatible and require cross-pollination to produce fruit. However, some self-fertile varieties, such as Lauranne or Mandaline, can produce almonds without a pollinator, although cross-pollination remains beneficial. Amandiverse, a specialist wholesale supplier of almond plants , supports growers by offering suitable varieties and advising on best pollination practices.
Orchard organization plays a key role in pollination efficiency. It is recommended to alternate rows between main varieties and compatible pollinators (e.g., Ferragnès with Ferraduel or Lauranne). Tree layout and the presence of pollinating insects also influence productivity. Honeybees (Apis mellifera) are the main pollinators of almond trees, but bumblebees (Bombus spp.) and wild bees play a complementary role, especially in difficult climatic conditions.
Introducing 4 to 10 hives per hectare helps ensure effective pollination. Colonies must be strong and well-positioned to maximize their activity. Amandiverse, a specialist wholesale supplier of almond plants , also recommends preserving biodiversity around orchards by promoting flowering hedges and limiting the use of pesticides that are harmful to pollinators.
Optimized pollination management can significantly increase yields and improve almond quality. Buying almond plants from Amandiverse ensures you have high-performance varieties that are adapted to the best agronomic practices.
A key element for almond production
Pollination is a crucial step in almond cultivation, as it directly influences fruit production and quality. Most varieties are self-incompatible , meaning they cannot pollinate themselves and require the presence of other compatible varieties to ensure fruiting. However, some self-fertile varieties, such as Lauranne and Mandaline , can produce almonds even when planted in monoculture. However, even these varieties benefit from cross-pollination, which can significantly increase yields and improve fruit quality.
Variety compatibility and cross-pollination
Self-incompatible almond trees must be associated with compatible varieties to ensure good fertilization. In France, Ferragnès is often chosen as the main variety, accompanied by Ferraduel or Lauranne as pollinators. Other varieties, such as Texas or Aï , can also be used depending on climatic and agronomic conditions. The key to ensuring effective pollination is the coincidence of flowering periods between the main variety and its pollinators.
Self-fertile varieties, such as Lauranne and All in One , can be planted alone, limiting reliance on pollinating insects and reducing the risk of adverse weather conditions during flowering. However, studies show that cross-pollination generally improves the productivity and quality of harvested almonds, even for these varieties.
Arrangement of varieties and layout of the orchard
Orchard organization plays a vital role in successful pollination. To optimize pollen transport between trees, it is recommended to alternate rows using a suitable ratio. The classic pattern is to plant one row of pollinators for every two rows of the main variety . In some situations, particularly where natural pollinators are in short supply, a 1:1 ratio can be used to ensure more efficient pollination.
The distance between compatible trees is another crucial factor. Ideally, it should not exceed 8 meters , to maximize pollen transfer by insects. A staggered arrangement or alternating blocks can further improve the efficiency of the process.
Pollinators and their essential role
Honeybees ( Apis mellifera ) are the main pollinators of almond trees. They are widely used in orchards for their efficiency in transporting pollen between flowers. However, other insects also play a key role in almond pollination.
Bumblebees ( Bombus spp. ) are particularly useful, especially in adverse weather conditions. They are more active at low temperatures and in low light, making them essential in areas with uncertain weather during flowering. In addition, they visit more flowers per minute and transfer more pollen than honeybees.
Native wild bees, although often overlooked, can effectively complement the work of honeybees and bumblebees. Promoting biodiversity around orchards helps maintain a natural balance and ensure effective pollination.
Hive management and optimal density
To ensure optimal pollination, it is advisable to introduce between 4 and 10 hives per hectare of almond trees, depending on the density of the trees and climatic conditions. The hives should be installed as soon as the first flowers appear , in order to maximize the availability of pollinators throughout the flowering period.
Bee colonies must be strong enough to ensure good pollination activity. A hive should contain at least 6 frames of bees , ideally 8 frames or more. The arrangement of hives in the orchard should be designed to facilitate the movement of pollinators: it is recommended to place hives in groups of 4 , ideally exposed to the morning sun to stimulate bee activity from the early hours of the day.
To strengthen colonies before almond blossom, some growers perform stimulation feeding about six weeks before moving hives to the orchards. This method ensures an optimal population of foraging bees when the flowers need pollination.
Environmental factors influencing pollination
Weather conditions play a major role in almond pollination. Bees are only active when the temperature is above 12°C , and they avoid going out in strong winds or rain. It is therefore essential to monitor weather forecasts and, if necessary, adjust hive management accordingly.
In cooler climates, bumblebees can be a good alternative because they can pollinate at lower temperatures than honeybees, ensuring better pollination in cold, wet springs.
The orchard's immediate environment also influences pollination quality. Planting flowering hedges and maintaining natural grass cover encourages the presence of wild pollinating insects and increases pollination efficiency. Additionally, limiting pesticide use and adopting agroecological practices protects pollinators and ensures better tree fertility.
Variety specificities and recommendations for optimizing pollination
Some varieties require special attention to ensure effective pollination. For example, Ferragnès is a self-incompatible variety that must be associated with compatible varieties such as Ferraduel or Aï . On the other hand, Lauranne , although self-fertile, sees its production improved when grown in the presence of other varieties.
Orchard organization must also take into account mechanical harvest management. Alternating rows of pollinators and main varieties while respecting the recommendations makes it possible to simplify harvesting operations and optimize yields.
To ensure effective pollination, it is recommended to regularly monitor flowering and adjust hive management based on weather conditions. Inspecting bee colonies can also be helpful to ensure pollinator health and maximize their effectiveness.
Conclusion
Pollination is a key factor in the success of almond cultivation. Since most varieties require cross-pollination, it is essential to carefully select compatible varieties and organize the orchard accordingly. Introducing sufficient beehives, using bumblebees in harsh climatic conditions, and preserving biodiversity are all levers that can improve yields.
Proper pollinator management, combined with appropriate cultural practices, not only ensures abundant production but also improves the quality of harvested almonds. In the future, it would be interesting to explore almond pruning techniques in more detail, in relation to their flowering and productivity.
To summarize: The importance of pollination for almond cultivation
Pollination is a key factor in almond cultivation. Most varieties require cross-pollination to produce fruit, which means combining different compatible varieties within the orchard. Amandiverse, a specialist wholesale supplier of almond plants , supports growers by providing them with the varieties best suited to market requirements.
Orchard layout directly influences pollination success. Alternating between main and pollinator varieties optimizes pollen transport.
