Timely and high-quality execution of spring work on the apiary has a significant impact on the development of bee colonies, their preparation for the main honey harvesting period, and their productivity.
Spring work on the apiary becomes much easier when strong colonies, consisting of at least eight frames, emerge from wintering. Such colonies do not require excessive labor or special care compared to weak ones. It should be noted that violating or failing to follow mandatory technological rules for bee management can lead to significant weakening and even death not only of weak colonies but also of those that have successfully overwintered. In the spring period, bee losses can sometimes exceed those during the entire winter.
The primary spring tasks in beekeeping include:
Colonies with weak flight activity must be inspected immediately. Unfavorable colonies are transferred into clean, dry hives. Old and moldy combs are replaced, food frames are added, and nests are reduced and insulated with dry cushions. Upper entrances should be completely closed, leaving only a small lower entrance for 2–3 bees. Frequent inspections during unstable and cold spring weather can lead to infection with nosematosis and a decrease in brood production and colony productivity.
Correction of weak colonies is only appropriate if they have a good queen that lays fertilized eggs, but development is limited due to a lack of young nurse bees.
In early spring, the beekeeper must pay special attention to hive insulation and heat preservation. Once brood appears, bees maintain a stable temperature of around 34±1°C in the hive. If the temperature drops to 32°C, brood development slows and bee quality decreases. If it rises to 37°C, part of the brood may die, and at extreme temperatures (28.2–28.6°C and 37.9–38.3°C), 100% mortality of developing bees may occur. Therefore, proper insulation is essential.
During the first warm spring days, hive cleaning and treatment begins. Clean bottom boards are prepared in advance and replaced. Dirty hive components are cleaned, scraped, and disinfected using flame. In cases of heavy contamination, colonies are transferred into clean, disinfected hives, and unsuitable combs are replaced.
Colonies with six or fewer frames must have their nests reduced. Frames are arranged so that bees fully cover the combs, which is important for heat retention and preventing brood loss. As colonies strengthen, nests are expanded. Weak colonies may be strengthened by adding 1–2 frames with sealed brood and young bees, while ensuring protection of the queen.
In spring, due to unfavorable weather conditions, nectar flow is limited. Therefore, sufficient food reserves are essential. If food is lacking, bees may fly even at temperatures of 7–8°C, leading to their death. Each colony should have at least 10–12 kg of honey and sufficient pollen stores. Honey alone is not enough for proper colony development.
The main purpose of the spring inspection is to assess the condition of each colony after wintering and create favorable conditions for intensive development and honey production. Colony strength, brood amount, food reserves, and queen quality are evaluated. Inspection is carried out without fully removing the frames.
The presence of a queen is determined by brood pattern and bee behavior. Frames containing brood confirm queen presence. Poor-quality, moldy, or damaged combs are replaced with clean, light-colored combs suitable for egg laying.
