2008 Garden Harvest Summary

Here it is almost Thanksgiving again and a great time to review the year's harvest totals and give thanks for the blessings from our garden.

As of Nov 10, most of the 2008 harvest is in(we still have a few carrots remaining). We had a bumper crop of honey this year and the bees were also busy in the garden with pollination.

We set new records this year for production of green beans, tomatoes. We lost our cucumbers and a few squash plants to bugs, but still did well on those. We missed most of early summer due to travel so the early crops like rhubarb, lettuce and cilantro were way down.

2008 harvest totals:
  • Basil (not measured)
  • Cantaloupe 2.0 lbs (why bother?)
  • Carrots 34.3 lbs (so far)
  • Garlic 0.5 lbs (volunteers)
  • Green Beans 26.9 lbs (new record)
  • Honey 312 lbs (new record)
  • Beeswax 3 lbs (new category)
  • Lettuce & Salad Greens 1.5 lbs
  • Onions 18.2 lbs
  • Peppers 62.1 lbs
  • Pumpkins 57.5 lbs
  • Rhubarb 7.0 lbs
  • Shallots 0.7 lbs
  • All Squash 322 lbs
  • Tomatoes 357.6 lbs (new record)

Fresh Onions
2008 Climate Summary:
The length of this summer's growing season was a bit longer than normal. We had our last frost of spring on May 11th and our first frost of the fall on October 7th giving us a little longer than normal 149 days of growing season. We had good rains in May and August this year, which probably helped the nectar flow for the honey production. Our total summer rainfall was also very close to normal with 7.94" from April through October with July being our driest month with zero rainfall the whole month. June was also dry, so the mid-summer required a lot of extra watering again this year.

Average temps were generally equal to last year through July, again without any days above 100 degrees. We had our only 100 degree day in early August, then it was a bit cooler from August through October compared with normal averages.

To Bee or Not to Bee

Anyone who has watched the news or picked up a newspaper lately has been witness to the extreme position in which the human race has placed itself. The precarious feeling of standing on a teeter totter with one foot trying to balance feeding the world, while the other is trying to balance nature and doing what is best for the earth. In one part of the United States we see farmers trying to defend their crops against the invading pests and just a few miles away we find a commercial beekeeper opening his hives to find that he lost up to 80 percent of his colonies over the winter. These two situations may not seem related but in fact they both have a common theme, the honeybee. This small, flying insect that seems to be as much a part of spring and summer as the gardens and flowers that they pollinate is in danger. It faces threats on every front. Unfortunately, we as a human race, are responsible for many of these threats from the pesticides that we use to the way we handle the bees. If these issues are not addressed soon, we could lose a valuable part of our food and our future.

The honeybee has been pushed into the news recently with the mysterious disease that is called, Colony Collapse Disorder, or CCD. During the winter of 2006-2007, there was a reported loss of 30% of all the hives nationally with the winter of 2007-2008 reporting 37% loss (Mendes 2). This is devastating news to the world’s food supply. According to the United States Department of Agriculture, every 3 out of 10 bites of food we take is thanks to a honeybee. They are directly responsible for pollinating crops like blueberries, almonds, squash, cucumber and most fruit grown on trees. They pollinate 15 billion dollars worth of food grown in America, annually (CSBA 1). With these figures in mind, the world is racing to find a reason for CCD. So far, there have been many theories ranging from pesticides to bad nutrition, but there is not a definitive answer. Perhaps, it is because it is not just a single cause but a combination of causes that have been waiting like a time bomb to explode.

Bees are an insect and they are not the only insect that is part of the equation. There are insects that are good for plants like bees, ladybugs and preying mantis. These insects pollinate and keep other insects that would destroy a plant under control. Then there is another insect that will eat and destroy crops. Farmers deal with the threat of these other insects destroying their crops. According to the Southeast Farm Press, this past June farmers faced the loss of their corn crop due to the stink bug. These insects can survive over the winter in wheat fields that were plowed in the fall and will be then planted in the spring with corn (Robinson 9).

Corn is important to the economy not only for food, but with the demand to steer away from the use of fossil fuels. With Ethanol now being produced from corn and used as another way to fuel cars, farmers are turning over more fields for growing corn. If their crops are destroyed they lose not only their income but America loses a valuable fuel source. Unfortunately, many of the choices that the farmers have in killing destructive pests also kills the other insects like the honeybee. One solution that farmers use is neonicotinoids. This is a group of pesticides that were introduced on the market in the mid 1990’s. “Basically, neonicotinoids block the insect neural action. In other words, affected insects often just sit around doing nothing until they desiccate, get sunstroke or become picked off by a predator or disease” (Shetlar 80).

So far, these pesticides have been effective in preventing pests, but at what cost? The pesticides that fall under neonicotinoids, which includes clothianidin, have already been banned in Germany and a similar insecticide banned in France. Germany’s Federal Agricultural Research Institute is quoted by the Sierra Club as saying, ”It can unequivocally be concluded that poisoning of the bees is due to the rubbing-off of the pesticide ingredient clothianidin from corn seeds” (Harmon par. 3).

The response to these actions in Europe has fueled the debate here at home but with the income and need for corn being so great it has been harder to get action. According to the Colorado State Beekeepers Association website, the Natural Resources Defense Council has filed a lawsuit against the Environmental Protection Agency, (EPA), for “withholding the toxicity of pesticides to bees”, they also are stating, “EPA granted a registration to a new pesticide manufactured by Bayer CropScience under the condition that Bayer submit studies about its product’s impact on bees” (CSBA 1). The pesticide in question, being manufactured by the Bayer Company, is one of these neonicotinoids. Why would the EPA not release the results of these findings? We could make lots of conclusions one of which could be the money that the Bayer Corporation has to help hide the issues. Let us not forget what David Hackenburg of the U.S. Department of Agriculture said, “Massive bee die-offs started occurring after regulatory agencies rubber stamped the use of neonicotinoid spraying and coatings” (Harmon par.7) .

Pest destroying our crops is not the only issue we have to take into account. There are also pests that are destroying the bees. During the mid 1980’s a threat was found to have invaded the U.S. beehives. This tiny threat is the mite. It has also had a devastating affect on the survival of our honey bees. The two main mites that can destroy a hive is the Varroa and the Tracheal mite. These mites have not been attributed as a cause of CCD but the way we treat this threat might be. Again the issue is a pesticide but this time it is one that the beekeeper used directly in the hive.

When the mite emerged on the scene, beekeepers rushed to find an answer and a quick fix. Keep in mind that commercial beekeeping is also a big money maker. Trucks carrying hives of bees are transported around the country to pollinate a specific crop. When the bees are done they will be packed up and moved to another field, perhaps across the country. If farmers do not have bees then their crops will not produce. Again we find ourselves on a teeter totter deciding between money and food and the bee. In response two hard pesticides were presented.

The first miticide to appear was Apistan and when mites became resistant to that then CheckMite entered the market. According to Bee Culture Magazine, “It is well known that both the above materials accumulate in the comb and can cause if not acute, at least persistent ongoing problems that interfere with the delicate biology of a honey bee colony” (Sanford 19). Keep in mind that both of these “miticides” are still sold in beekeeping catalogues today and even encouraged to be used. In the book, Beekeeping for Dummies, written by Howland Blackistan he says, “Regardless of whether you detect varroa mites, I suggest that preventative miticide treatments be administered to your hive once in the spring and again in autumn” (A180).

The fear of what might happen is often the reason preventative medicines are used. We have seen this example in humans. For too long doctors prescribed antibiotics to children to prevent them from getting sick and now we have found that many diseases have mutated or become resistant to the very thing we used to prevent it. So too is the case with the bee. Bees, like humans, have always had a chance of getting sick from certain diseases. Foulbrood is one such disease. The way to treat it is antibiotics.

Antibiotics are helpful when used correctly. That statement is also true when caring for a hive today. The problem is that many beekeepers feel pressured to give these antibiotics regularly as part of their seasonal management of their hives. They have been scarred by the threats that bees are facing and trying to keep up with the quick fixes that we as humans try to pass off as science. Bruce Royden Brown of CC Pollen Co explains, “Science tries to present a stable picture of its findings and in the end, it’s only partial, fragmented truth that is always moving”. He also adds, “Most science is driven by economic, profit driven pressure”(A1). In the end, a beekeeper is once again trying to perform a balancing act, how to protect their hive from disease and how to stop the weakening trend of bees in general.

Any beekeeper who has lost a hive can tell you of the guilt that is felt. To see a hive become sick or weakened, to open a hive at the end of a long winter only to find that it is dead or queenless is a beekeepers nightmare. They find themselves asking what they could have done to prevent it and could they have done more. These are the feelings that companies who sell the medicines and antibiotics play upon when selling their products.

Let us try to imagine the guilt that would be felt if we lost the bee population. Could we survive the loss of such an important part of our ecosystem? Bees have survived for millions of years without the aid of humans but may be destroyed by the science of humans. In our response to this situation we need to step back and take a look at the bigger picture. Colony Collapse Disorder is the current disaster hitting our environment but it’s really just a consequence of our over indulgent behavior concerning pesticides and our intrusive behavior into a highly organized part of nature. If we are going to succeed in balancing food and nature we need to take money out of the equation. Perhaps Bruce Royden Brown said it best, “Go back to the basics; give the bees what they need…It is vitally important for us as human beings, maybe even for reasons beyond our comprehension” (A4).

Pesticide impact?

A brief update on the hive troubles: We continued feeding today with leftover honey. We made about 8 lbs available for each colony in the hive-top feeders. It was certainly warm enough for them to take it today. We'll see how much we can get them to pack away before it gets too cold.

I spoke to the former president of the local bee club today. He said this problem seems to be fairly widespread throughout Boulder County this year. He has some theories that it may be related to neoniconoids (a type of pesticide) being used on local corn crops. His advice was add a pollen patty to affected hives to see if that will get the queen laying again.

They're in trouble!

We've had some nice warm weather this week and the wind was calm so we did an inspection today, Nov 1. What we found was rather disturbing. The bees, both hives are in real trouble now, and just a few weeks ago everything looked great. Most of their honey reserves were gone and there was virtually no brood. What happened? Will we loose them?


This frame is one of the best frames from the upper deep of Hive-1's honey reserves, most were completely empty. Just 4 weeks ago, these were completely full.


Going downstairs to the brood chamber revealed frames like this. Most were just empty and a few had some pollen and we saw only about a few dozen cells with capped brood, no eggs, no larvae, just empty cells. Are they queenless?


Hive 2 wasn't doing much better. We found most of the frames empty and in the uppermost chamber there were just four frames at the far north end of the hive that still had capped honey like this one. Since they seldom venture to the north end of the hive during the worst of winter, I decided to move these 4 frames with the honey closer to the middle of the upper chamber.


Hive 2's brood chamber was also mostly empty now. Like hive 1, we saw a few cells with some pollen and just a few cells with capped brood, but no eggs, no larvae and very little honey. We couldn't find the queens today from either hive. Hive 1 was quite agitated and we ended up having to put our gloves on in the mayhem, which made it a bit hard to snap some pictures.

In our panic, we decided they urgently needed some food. After we closed up the hives I went back and returned with 8-10 partially capped frames we didn't harvest from September. Most had open cells of nectar and a few were partially capped with honey. I set these about leaning against the hives for feeding and they were all over them in just a few minutes. They were having a feeding frenzy the rest of the afternoon. We have a bit more unprocessed honey we will try to feed them tomorrow, but if they are really queenless, it probably won't help.

These bees were so good to us this past season with the tremendous production and now it looks like something has gone terribly wrong. We hope they find a way to make it somehow.
