There may seem to be an abundant variety of the right plants blooming at the right time, but if every urban yard hosts a substantial bee colony, the bees will not all have enough plants to pollinate. The Guardian newspaper notes that London has seen an unprecedented rise in urban beekeeping in recent years, and some experts are beginning to worry if the bees are exceeding sustainable levels.
The article notes that researchers have yet to quantify the number of bees that an urban yard can support. Again, there are a number of complex variables that differ from place to place and month to month.

Finally, a lack of honey or a problem in the hive could be attributable to colony collapse disorder. The large-scale bee die-off was identified and defined in 2006, but has not been definitively diagnosed.
One theory links colony collapse disorder to pesticides and large-scale commercial beekeeping practices that move bees out of their natural habitats. However, other studies have connected the problem to electromagnetic waves, particularly from cell phones.
In one study released this year in India, researchers attached cell phones to bee hives and turned on the phones for two 15-minute periods each day. Three months later, the bees had stopped making honey and the hives had shrunk significantly.
There are many possible reasons for a drop in honey production from an urban bee hive. If the above tips donít help, consult a local beekeeping society, where they would be happy to help.
