Getting an oil-seed-rape harvest gets harder as each year goes by. This year, what the bees were able to forage in the first week of flowering they ate themselves in the five terrible weeks that followed. Fortunately the field beans over the road played a part in bringing the harvest up to an acceptable level. No nice creamy white stuff with which to blend unfortunately.
I have now completed six extraction sessions. Clearer boards, of which I have quite a selection were put on first thing in the morning beneath the full supers. Put them on any later in the day and the bees have had an opportunity to gather more nectar and fill any unfilled or partly filled cells. This is all unripe so raising the average moisture content of the honey.
So, clearer boards on very early then supers gently off late in the day without disturbing them. Next morning can then be devoted entirely to uncapping and extracting with the wet supers going back on late in the evening. Put them on earlier and the sudden blast of honey aroma can cause great excitement with consequential robbing
As an afterthought; how pleasant it is to work with such well behaved bees. Queen selection and rearing means that usually, I can do a brood-box inspection with just one or two puffs of the smoker.
What had seemed an amazing start to the season rapidly turned sour. The marvellous weather we had in March enabled supers to go on eight of the hives earlier than ever before. April arrived, the oil-seed-rape came on flower, and the weather turned for the worst; next to no rain meant no nectar and the bitterly cold winds meant the foragers could not leave the hives. These conditions lasted for almost the whole of the rape’s flowering season. Some of the hives got up to two supers but I added the second just to ensure there was plenty of space to store any incoming nectar.
Varroa counts have continued on a weekly basis and Stuart Roweth (www.beegym.co.uk) has kindly supplied some more up-to-date beegym equipment. His floor-mounted model has been upgraded once again and these are installed in hives 7 & 8. Hive 9 has ten of the new production model minigyms.
Varroa has unfortunately been the least of my worries. Last year I had a severe case of CBPV (Chronic Bee Paralysis Virus) in hive 8 which I managed to clear by hand-picking all the infected drones from the combs. This year the virus has swept through all the colonies killing thousands. Being confined to their hives has exacerbated the problem because it meant that infected bees were not dropping out of the sky away on foraging trips but were staying at home to share the infection with their brothers and sisters. To add to the misery I also had cases of DWV (Deformed Wing Virus). Each day the ground in front of the hives has been littered with dead bees, to the extent that I got ‘The man from the ministry’ to come and have a look. He confirmed not only my diagnosis but the fact that there is no known cure. He scooped up several handfuls of dead bees, put them in a carrier-bag to send off for analysis just in case there was something else we hadn’t noticed. All we can really hope for is more rain at night and more sunshine in the day.
Over the road is a crop of field beans just about to come on flower but whether they’ll yield a harvest for me as well as the grower remains to be seen.
On a less despondent note, the Saffron Walden beekeepers group had a trip out to Kew Gardens to see The Hive. A marvellous edifice in stainless steel complete with lights and music. Not a lot to do with bees unfortunately, apart from the interior shape, which resembled a skep.
