Re: HYB: avoiding contamination in crosses


I haven't been too concerned with bee pollen, but I have had some questionable seedlings.

I would suggest large hairnets.  They allow the bloom to expand almost fully and also allow the free movement of air which keeps the temperature lower than using something like a paper bag.  I haven't used them on Iris but on other things like sunflowers.  On sunflowers it is absolutely necessary to tie the hairnet around the stalk below the flower as all kinds of bugs get in there after that delicious pollen and nectar.  You may need to do that if for nothing else to keep it from blowing away.

Here are some links I have found to purchase them from.
