Dutch irises differ from other irises in that they grow from bulbs rather than stems. Dutch iris ideal for cut flowers. In fact, commercial florists make a big business of growing under glass for this purpose. However, it is not necessary to bring the glass house into flower, as they are excellent green subjects. If these irises are grown for cut flowers in the home garden and the bulbs are missed for the next blooming. year, the stems should not be cut to the ground.
The lower leaves must be left so that the food in the bulb will feed the neighbor to feed. In commerce, the bulbs are considered expendable, for a few extra cents per dozen, the stems being cut as long as possible. For cut flowers, the stems should be cut just as the first buds begin to open their petals. The foliage in these irises is small, and the flowers are all located at the top, so they are more attractive spotted when planted in bunches or on the plane where the leaves of other plants hide their leg.
I never feel guilty when I suggest planting Dutch rainbows by the dozen, which are so cheap and give so much value for money. If space is in doubt, plant them with hyacinths and daffodils to get a longer flowering period from them. Dutch iris Bulb plants half the height of tulips, hyacinths or daffodils, their roots will not take up space. necessary for these earlier flowering bulbs, Sydney Mitchell, a hybridizer widely recommended for scattered colonies, if the Dutch Iris is interspersed among the long-bearded Iris varieties.
Dutch Iris bulbs can always be moved to a new location when their bearded relatives start to get too close. Dutch iris plant bulbs four or five inches high, depending on the gravity of the soil. They prefer light, soil in sandy they prefer a well-drained part but they will bloom well in heavy soil if it is well drained and compost is lifted.
You will find a place for them where they will be protected from the midday sun and the wind. They are supposed to be like full sun, but we find their greenness much longer when it is covered for the least part of the afternoon. Remember that a new bulb needs foliage to help grow the flower of the year so leave it intact until it fully matures. the bulbs can be lifted after the leaves are mature but we have found that we can leave them alone for two or more years and still have a good bloom.
Almost the only disease that affects the Dutch iris is mosaic, which is easily recognized by the streaking of the leaves. The best treatment is to pull out the infected plants and destroy them. You can plant the Dutch iris in the same place as the other planting, if soil grows and nutrients are supplied. by sprinkling bone meal at the rate of half a pound per square area. Thus the mosaic disease is not borne by the son. transmitted only by bees infecting plants.
