The thick and fuzz of it all is -insects do the job better than you.
Recently, I grew cucumbers in a garden; with no idea, there were no pollinators. I had never run into such a problem. I did not catch it in time to rectify. Hence several, hundred blossoms died without fruiting.
While I hand pollinated, I looked for a quick fix. I concluded that quick fixes cost more than I could afford. Hand pollinating only produced 1 fruit per 20 blossoms. This is hardly efficient.
I firmly believe mistakes are opportunities to grow. It was later discovered that the surrounding neighbors used pesticide and the homeowner was using a weed killer. This killed the native pollinators. After a great deal of research, I found I was too late in the season. Next year, however, I will be armed with knowledge and a small army of pollinators. (Avoid pesticide that kills pollinators by consulting The Xerces Society)
The pollinators that will survive in this area; that I could introduce to a garden are:
Search for pollinators and suggestions in your area using Pollinator Partnership.
Tachinid and Syrphid flies are a good low upkeep option.(2) Tachinid flies reduce insect pests. Flies were ruled out because to attract them you want to grow pungent or offensive smelling flowers.(3) Even then, flies are not attracted to every type of blossom.(4) Also, Tachinid flies will eat flower blossoms.
Bumble bees and honey bees are great choices for those that:
*Want honey or wax (bumble bees are far less productive on both counts)
*Do not have city regulations against having hives
*Have no allergies
*Cost is not a large factor
I thought that neighbors would be a concern as well; however, several forums stated unless you tell neighbors they tend not to notice. (Bees swarm around or near a hive, but thin from there.) Honey bees would have been my first choice; however, bumble bees and honey bees are territorial and aggressive.(5) Daniel is allergic to bees. Also, my dog regularly tries to eat bees. Colony bees are more susceptible to disease and invasion.(6) Eventually, when I have an orchard I will have honey bees, a bee suit, and an emergency EpiPen. For now, honey bees are too high risk.
Squash bees can have 135 bees per acre to sufficiently pollinate a crop.(7) Honey bees need a hive (20,000-80,000 bees)(8) per acre.(9) Solitary bees collect 60 times that of a colony-worker bee.(10) In conclusion, solitary bees are actually better at pollinating flowers.
There Bite is Weak
Solitary bees are nonaggressive. Females do have stingers. Unless you trying to squish them they will not sting. In addition, their sting is less venomous than a mosquito.(11)
The Solitary Life
Solitary bees are just that, solitary. Each female solitary bee gathers nectar and produces offspring.(12) She will collect nectar for herself and as a store for her offspring. And she’s good at her job. After belly flopping on as many flowers as she can, she will return to her home. She will regurgitate the pollen she has been collecting. The solitary female bee will fill up a cell with the regurgitated pollen (bee butter). She leaves one of her eggs in each cell.(13) She caps the cell off with a mud or clay wall. She will continue to make cells until her life cycle is complete. On average this leaves 5-6 eggs. They will hatch as larvae, eat the bee butter, and pupat. Then they will cocoon themselves for the winter. Finally, the solitary bee will emerge. This will happen in the spring or summer.(14)
Solitary . . . Kinda
These little pollinators room and board in their own wooden reed. However, there are several reeds stacked together to make up what is called a “bee hotel”. Hence, bee hotels ensure genetic diversity, breeding, and enough pollinators in an area. A bee motel can be created from wood or paper or actual reeds. Plastic is a no-no (it doesn’t breath). (15)
What You Need
Things you will have to provide for solitary bees
*Clay or Mud
*Pollen if it’s a rough season
There is very little time invested in the upkeep of solitary bees. Sometimes you will want to provide extra reeds or relocate the excess. It is suggested that you keep the reeds from freezing otherwise leave them bee.
Not all Solitary Bees are Created with Equal Tastebuds . . . or Timing
There are over 4,000 types of native bees according to, to the US Forest Service. It is noteworthy, different type of bees emerge at different times. Therefore be aware of this when you order solitary bees.
Buying An Army
After scouring the interwebs I decide on a Crown Bees Starter Kit. It has spring, summer, and fall solitary bees. Solitary bees are adaptable. So you can feel comfortable ordering from masonbeesforsale.com, located in California. You will receive the bees in reeds. These will be reeds will contain cocooned adult solitary bees waiting for their season. So keep the reeds in a cool place during the winter. Solitary bees have a travel radius of approximately 200 feet.(16) It is suggested not order less that 20. If you want bees for next year you want enough bees to repopulate. Having more bees results in having enough genetic differences and calculates for loss.(17)
