We grow cucumbers in our greenhouse because the season is so short here. In May, after we hang netting that has large spaces in it from the roof of the greenhouse, we plant our seeds in the soil of the greenhouse floor. Then we put black plastic between the rows to keep the weeds down and to heat up the soil. Yes, we have weeds, they blow in the open windows and doors and we bring them in on our feef and clothes. After that, we sprinkle Concern, ( diatomaceous earth, organic crawling insect killer), over the seeds before they come up.
You should be able to order Concern, at gardening stores or gardening catalogs. See the post (: https://51chevy.wordpress.com/2008/01/22/catalogs-that-…nhouse-growing/ ) If you still can’t find it click this site http://www.victorpest.com/search?page=1&search=concern. Concern kills crawling insects like slugs and pill bugs that eat plant shoots and young plants. It can be used in the garden, on house plants, or in the greenhouse.
I recently learned that Concern, cannot be shipped to all states, however, another product called Safer, diatomaecous earth can. Go to http://www.saferbrand.com/store/insect-control/51702 to order on line.
There are two different kins of diatomaceous earth, one is used to filter swimming pools. This type should not be used as it is dangerous to breath it in because it can cause lung damage. The variety used for gardens is a much finer powder and does not pose a health hazard.
As the cucumbers grow up the netting you must weave the vines in and out of the netting spaces. This is necessary in order for the vine to support the weight of the cucumbers as they grow.
