This Iris pallida 'Argentea Variegata' has been struggling since I planted it. It actually is smaller than it was, but finally looks more healthy now. Looking closely there is a baby Iris growing on the right side. Do they like fertilizer and if so what kind? Thanks for any assistance. Xuling
we grow many pallidas but the non-varigated variety called Dalmatica and Princess Beatrice and were getting Empress of India this year, they love bonemeal in the Spring something like 4-10-10 or 10-10-4 i believe in the fall, we usually put the bonemeal down with epsoma bulbtone that has the benificial microorganisms and the alfalfa meal in it down about a week or two after the bonemeal, they also like their roots gnarled up real close to the surface as they do not like much water or moisture or to be planted too deep. they do fairly well in semi shaded areas too where as most TB iris need direct sun, they also do not need to be separated as much as other bearded iris species like germanicas, they seem to like to be crowded to some degree forming large colonies especially at abandoned homesites and in the wild. I guess this makes sense as they come from the dalmatica coast of former yugoslavia near present day croatia which is very arid and windy and cold at night kinda like a desert I understand with alot of rocky vegetation-less cliffs where no ones around to divide them and not alot of rain either.
