Help Honey Bees Survive This Winter

Honeybees are far and away the most important pollinator in today’s agricultural landscape. They pollinate more than 400 crops worldwide, help to create about a third of the food we eat, and contribute an estimated $12 billion to our nation’s food supply.
 All summer long, worker bees can be seen buzzing between flowers, collecting pollen and nectar and, in the process, pollinating vast tracts of crops (upon which we depend) and producing an abundance of honey (some of which is ferried away by beekeepers to local markets for us to enjoy). As summer draws to a close and the weather starts to cool, one of the questions I get a lot is, “What happens to bees in the winter?”

 People often guess that honeybees hibernate; others presume that colonies die as cold weather approaches. Fall’s first frost does kill most members of bumblebee and yellow jacket colonies, leaving lonesome queens to establish new nests each spring.

But honeybees are different.
They’ve evolved a strategy for winter survival that is unique, one that relies heavily on frenzied visitation to flowers throughout the summer and a Herculean group effort in the months beyond. Believe it or not, their success in this endeavor depends on choices that you make for your yard and garden.
Honeybees need their calorie-rich, carbohydrate-loaded honey to keep them alive during the winter; it’s the perfect furnace oil for colonies. Worker bees eat this liquid gold and use the energy it provides to fuel rapid contraction of their wing muscles. Pumping these muscles without flying produces heat in the same way that shivering helps us to warm our own bodies.

As temperatures drop, honeybees cluster together within their hive to share the warmth that their honeybees to keep the inside of their home virtually tropical while the rest of the natural world remains frozen beyond the hive’s walls.
“shivering” generates (picture a ball of bees a foot in diameter and sliced through by sheets of honeycomb). At the core of this cluster, worker bees keep themselves and their queen at a temperature that is only a few degrees lower than that of a healthy human. The cluster’s outer layer consists of tightly packed, slightly cooler workers that insulate the core as effectively as bird feathers or mammalian fur—don’t worry, everyone gets to rotate. This remarkable group behavior allows
Here’s where we come in. Honeybees in temperate climates have only a limited window—about 60 days in total—to stockpile the food reserves that they will live off for the rest of the year. This means that we need to do everything we can to create an environment that lets bees succeed as pollinators when the going is good. Here are three ways you can help bees survive winter:

Plant late bloomers. When it comes to enhancing your garden’s fall bloom, consider adding late-flowering plants like goldenrod and asters that are critical to a colony’s final push to bring home food for the winter.

Avoid systemic pesticides. Certain pesticides have toxins that invade all plant tissues (instead of just living on the plants’ surface), and bees bring these chemicals to their nests when they collect nectar and pollen. A group of chemicals called nitroguanidine/neonicotinoids has been shown to contribute to colony collapse disorder.

Encourage early-spring blooms. Spring brings welcome relief for honeybees with a chance to restock dwindling floral supplies. Flowering trees—willows, maples, and the like—provide some of the earliest opportunities for bees to forage, so try to encourage their toxin-free growth when you can.

How to Store Apples for Winter

Interested in storing a bushel of apples to enjoy over the cold winter months? Once you learn a few storage tricks, it's easy to do.



1. Start with apples that keep well. Late-ripening varieties (those harvested in October) usually do best. These include: Red Delicious, Ida Red, Winesap, Crispin, Stayman, Rome, Northern Spy and Turley.

2. Inspect all apples for bruises, cuts and soft spots. Only perfect fruit is suitable for storage.

3. Sort the apples by size: small, medium and large. Since large apples don't store as well, this will make it easy to ensure that they get eaten first.

4. Place the sorted apples in perforated plastic bags or in boxes lined with perforated plastic (to allow for air circulation).

5.Store in a cool basement, garage, fruit cellar or refrigerator. The ideal storage temperature is 30-32°F with 90% humidity. Apples are likely to suffer freeze damage if the temperature dips below 30° and will ripen quickly, if the temperature rises above 40°, so do your best to match these conditions.
Check regularly for signs of spoilage, and remove any damaged fruit.


Tips:

1. Pick apples when they are ripe. Over or under-ripened fruit will not store well.

2. Store apples as soon after picking as possible.

3. Avoid storing your apples near onion or potatoes. They'll readily absorb the flavor of other foods.

4. Don't mix apple varieties. Different varieties ripen at different rates.

5. Expect your apples to last up to five months in storage (depending on variety and storage conditions).
