Why do iris plant bulbs grow better in tree shave?
The bulbous Irises, which includes Dutch Iris & some Reticulated Irises can grow in full sun to light shade. http://www.tesselaar.net.au/growingguide… They bloom early in the season when the area under the trees are actually sunny at that time…because the trees don’t have their leaves yet. This is similar to planting sun-loving tulips under trees. The Bearded Iris needs full sun but aren’t planted under trees. They bloom later in the season & wouldn’t do well growing under trees because it’s too shady for them. They have rhizomes that would rot in an area that’s too shady. They like the sun beating down on them through out the summer. Iris Lazica is different from other rhizomatous Iris & “enjoys light shade and moist soil. The best place to grow it is in a sheltered spot in dappled shade.” http://www.webgardenguide.c
