Spring Bloom: Willow, Fruit Blossom, and Rapeseed

After winter dormancy, colonies must grow to 40,000-60,000 bees within just a few weeks. This is only possible with sufficient early spring forage. Here you will learn about the most important early forage plants.

Spring Calendar Overview

Hazel (Corylus avellana) -- The First Pollen Provider

Hazel opens the forage year -- often as early as January or February when milder temperatures occur. It is a pure pollen source (wind-pollinated, no nectar), but this pollen is enormously important for the spring development of colonies.

Other Early Spring Bloomers

In addition to hazel, snowdrops and winter aconite (from February) as well as crocus and coltsfoot (March) provide early food -- particularly important in gardens, parks, and along road embankments.

Willow (Salix sp.) -- The First Major Forage

Willow bloom is to bee colonies what the first strength training after a break is to athletes: the starting signal for full performance. Willows are the first forage source that offers both abundant nectar and high-quality pollen.

Beekeeping Significance of the Willow Bloom

The willow bloom marks the beginning of the active beekeeping season:

• Colony development: The protein-rich pollen supply enables intensive brood rearing
• Feed consumption: Caution! Right now a colony can quickly deplete its winter stores due to brood warmth -- feed checks are essential
• First inspection: The willow bloom is traditionally the time for the first thorough inspection of the year
• Restricting space: Weak colonies benefit when the brood chamber is reduced so that warmth can be better maintained

The goat willow bloom is the single most important event in the bee year. Those who have strong, healthy colonies at this point are on the best path to a successful year. Those who already see problems here must act immediately.

Fruit Blossom -- Pollination Service and Honey Harvest

Fruit blossom (April-May) is one of the most important forage periods of the year. It provides both good nectar and high-quality pollen, and is simultaneously the phase when bees perform their crucial pollination service.

Fruit Blossom in Detail

Honey from Fruit Blossom

Pure fruit blossom honey is rare because fruit varieties and other forage sources (dandelion, rapeseed) overlap. In fruit-tree-rich regions, an aromatic spring blossom honey can be harvested.

Dandelion (Taraxacum officinale) -- The Yellow Meadow

Dandelion is among the most faithful allies of the bee colony. It blooms reliably, abundantly, and over a long period.

Dandelion Honey

In extensive grassland regions (Alpine foothills, Eifel), monofloral dandelion honey is possible: intensely yellow, bold-spicy flavor, very rapid crystallization (high glucose content). A regional specialty commanding a premium price.

Maple (Acer sp.) -- The Inconspicuous Mass Provider

Maple is often underestimated as a forage plant but is one of the most reliable nectar providers of spring.

Rapeseed (Brassica napus) -- The Mass Forage

Rapeseed is the forage plant par excellence for beekeeping in Germany and much of Northern Europe. In no other forage flow are similar honey quantities brought in over such a short period. The intensive rapeseed bloom transforms entire landscapes into brilliant yellow -- and for bee colonies, it means peak performance.

The Challenge of Rapeseed Honey

Rapeseed honey is Germany's most popular honey -- mild, creamy, light. But its extraction requires vigilance:

1. 1

   Migrate to rapeseed

   If your location is not already near rapeseed, migration to rapeseed fields is worthwhile. Place colonies 1-3 km from the rapeseed field. Do not forget the migration permit and health certificate (required in Germany and many EU countries)!

2. 2

   Add supers in time

   The rapeseed flow is so strong that colonies quickly need space. Supers that are too tight lead to swarming impulse. Better one super too many than too few.

3. 3

   Extract early!

   Rapeseed honey crystallizes extremely quickly (high glucose content). Extract at most 3-5 days after the end of the flow, otherwise the honey solidifies in the combs and can no longer be extracted. Many beekeepers extract twice during rapeseed flow.

4. 4

   Cream by stirring

   After extraction, let the rapeseed honey develop fine crystals through controlled stirring. This produces the popular spreadable, creamy-white rapeseed honey.

Rapeseed and Bee Protection

The relationship between rapeseed and bees is not entirely straightforward:

Other Important Early Bloomers

In addition to the main forage sources, these species provide valuable early forage:

• Cornelian cherry (Cornus mas): March, nectar value 2, often even before the willows
• Blackthorn (Prunus spinosa): March-April, nectar value 2-3, white clouds of blossom in hedgerows
• Hawthorn (Crataegus): May, nectar value 2-3, intensive forage in hedgerow landscapes
• Horse chestnut (Aesculus hippocastanum): May, nectar value 2-3, pollen value 3, nectar guides change color (yellow = fresh, red = empty)

Regional Differences

Spring forage varies considerably by region. While the following examples focus on Germany, similar patterns apply across Central Europe with timing shifts based on latitude and altitude:
