I know the feeling of too many irises! I had to cancel all of my orders this year because I was going crazy with the drought and the scorch and the cash flow drying up along with the pasture, so I was quite chagrinned to find out that I had forgotten to cancel one order and it is on its way! Do you think covering a row of newly planted irises with cheesecloth would keep out the leafhoppers for awhile?
