On our farm , Mockingbird Meadows , in central Ohio , we ’ve been living and knead alongside our bees for almost 10 years . They ’re an amazing plus to both our vegetable and herb production . One of the space we ’ve most enjoyed take in them is our greenhouse . We began to wonder how we could help their work on a more purposeful exfoliation .
nursery pollination around the earth is typically done bybumblebees(Bombusspp . ) , fascinating creatures that do their jobs well , especially in enclose spaces . There are argument in favor of take the bumblebee over theHoney bee(Apis mellifera ) for this case of work : They ’re active at lower temperature than the Honey bee , are more efficient pollinators , work out later in the evening and in the beginning in the morning , are native to the United States , and are less probable to sting you and your worker . When I first begin researching greenhouse - pollination solution , I was almost swayed by the humblebee ’s merits — and coming from a Honey bee keeper that say a lot .
I was ready to jump on the humblebee bandwagon until I read the ok print : The bumblebees ’ life cycle does not loan itself to a sustainable glasshouse pollination dodging . They dwell only four to 12 weeks , meaning you constantly need to purchase new colony . Contrast that to a Honey bee queen that subsist more than 2 years and continue to lay eggs , replacing workers as they conk and conjure up a new queen if needed , and that puts me firmly back in the Honey bee coterie .

Two Pollination Solutions
Agreenhouseis a challenging blank space to advance natural pollination . On our farm , we have 35 stand - alone Honey bee hive . Our pocket-size nursery is 12 by 24 metrical unit , and we allow pollenation to take place during the summertime by opening the top volcano and front doors of the greenhouse during the day . If your need are limited to your distinctive grow season , using Honey bees for pollination can be this simpleton . Just locate a hive next to the greenhouse and be certain it is approachable to them from early morning until after the sun has fix in the evening . This duration of time allow the last stragglers to render home without get trapped .
However , if you ’re attempting to grow in a magnanimous nursery infinite or are trying to extend your spring up time of year , only having a beehive somewhere on your land will not address your needs . At this point , you might want to place a beehive directly in the greenhouse . This voice round-eyed , but in reality require quite a bit of planning . In the elevation of summertime , a expand colony can turn back upwards of 60,000 bees — that ’s quite a lot of bees to negociate when you desire to work in your greenhouse .
Bring the Bees Inside
Regardless of the size of your greenhouse , it ’s not advisable to keep bees shut inside at all times . Whiletomatoesare alimental , if you ate nothing but tomatoes every day , you would get sick . bee also need a diversity offood ( aka pollen ) sourcesto maintain a healthy diet . set up your greenhouse to provide access to both its DoI and the great out-of-doors will help your hive thrive .
Locate your beehive on the inside bulwark present southeast so as to take advantage of the earliest warmness usable each day as the sun uprise . This placement will get your bees work as early a possible for maximal production . Remove a glasshouse board , situate the beehive in the opening and seal off around the hive to keep your greenhouse weathertight . If your glasshouse is n’t empanel , you could also reduce the hive entrance to a PVC tube that provides an exit from the hive to the humankind outside your complex body part .
award bees approach to the glasshouse will also be shape by the beehive complex body part . Regardless of which structure choice you use , you ’ll need to drill a small expiration hole for the bee . Place a obliterable covering over this hole ; originally , we like wire interlocking , but the bee insist on satiate this up with propolis to keep out the light , so we ended up repurposing a vino - feeding bottle cork . The corked hole gives your settlement ample access to the outside , but when you dispatch the covering inside your greenhouse , they ’re also gratis to pollenate your indoor crops .

Ventilation is important for both your plant and for a glasshouse hive , so locate your colony in an area where devotee supply plenty of circulation . We have found it necessary to place telegram mesh over the back housing of greenhouse fans when pollenate with Honey bees . Without a barrier , members of your pollination workforce can be pulled into the buff and killed .
Winter To-Do List
Your glasshouse beehive will call for superfluous attention throughout the year . In wintertime , our standalone beehive are reveal to temperatures that signal the bees to form their wintertime clump . They forbear from leaving the hive until the melody temperature is between 60 to 65 degrees F. An unheated nursery hive might have temperature fluctuations that boost flying during the day and clustering at night . If your greenhouse is fire up , the bee will definitely require to fly most mean solar day . It is n’t necessary to stymy their entrance to the remote world during cold 24-hour interval — they will only pilot out when it ’s warm enough . Whether or not you stir up your nursery , you ’ll probably take to have ample honey stores in reserve to feast them when they can not add on their diet outside .
It ’s probably a good idea to have a plan in home for “ thinning the herd , ” so to speak , especially if you have a heated greenhouse , because the bees will cover to turn their settlement . You could utilise this glasshouse beehive to move frames of worker and brood into weaker outdoor hive during the warm month , increase your cognitive process or help otherbeekeepersget commence with native - engender nucs . However you do it , you ’ll want to keep this settlement at a manageable size — watch for clusters hanging off the front porch or signs of swarming just as you would with an outdoor hive .
If you ’re a beekeeper hoping to use bee in the nursery , be prepared to go through a piece of trial and error to take up a balance between your colony size and the size and purpose of your greenhouse .
Honey bees are unquestionably not the most popular selection for greenhouse pollenation . There are a number of drawback , including less efficient pollination and potential overcrowding . However , they ’re worth a second smell , specially if you already have bee colonies on your farm or are interested in a sustainable solution .
