I have many dahlias that I overwinter every year. I bought 2 new kinds last year,dinner plate light purple witch grew very large last year, at least10" blooms,the other is bicolored,light pink and yellow,this did not grow as large. this year the pink/yellow is growing huge,many blooms and i'm having trouble w/the purple. so I took out magnifying lens,the leaves are mottled w/very tiny black lines. they are also stunted in height. I researched insects and can't seem to find any that match, they are not aphids-to small,they seem to me to be mites but no webs and i'm seeing mottling on many of my other dahlias.what to do? anyone having this problem? don't want to loose them/save them every yr. reading earwigs,what does larva look like? lost some to voles,moles because can't find them in garden were planted and had a bad problem.nothing really growing right this year.garden web mail response mc 1720161318099ec rosa.abbystractkat@cox.net
