Facts about the Iceberg Rose
The iceberg rose is one of the most popular roses of all time. It is now available in pink as well as in its original brilliant white. The iceberg rose was a Gold Medal winner in the 1980s. As a floribunda, it is not a fussy rose that demands a lot of time and attention, but just about as easy a rose to grow as you can find.
Many people get the iceberg rose to make a four-foot hedge that is not only protective of their privacy but which has among the most beautiful of all roses. These roses bloom all summer long and do not need all of the extra little touches like many of the newer rose cultivars. If you water them regularly and give them nutrients in the form of fertilizer at least once a month, they are really quite content to do nothing but bloom all season long.
Anyone who lives in USDA hardiness zone 5 and above can grow this floribunda rose. In fact, if you like climbing roses better than bush roses, you are in luck here too as you can find a version of the iceberg rose that is a climber. You should do a bit of pruning in the spring, water, fertilize and just sit back and enjoy your roses. If you do live in a colder climate such as zone 5, you would profit from covering the base of your plants with a nice mulch for the winter.
However, people who do not mulch also report that this rose springs back nicely from the winter every year. And if you live in an even colder zone, like zone 4, gardeners say you can still be successful with a floribunda rose as long as you make a mound of mulch that is at least a foot deep around the bottom of the plant. Roses can take a year or two to establish themselves so don’t expect an abundance of blooms the first year. But, as long as you plant it in the sun, water and fertilize, you will be pleased with your iceberg rose.
Don’t let the thought of pruning roses scare you away from this easy-grower. Very little needs to be done. If you have new roses, you will want to cut them back to around six inches. Older, established roses will need to have any diseased limbs cut off and the rest scaled back to around three feet. Leave the half dozen strongest canes. Pruning can take place after the flowers have gone by or in the early spring before new growth begins.
An iceberg rose should receive approximately two gallons of water every week throughout the growing season. Fertilize at the start of the growing season and then once a month until the end of July, and that is all the roses need. They like organic fertilizers, such as dried manure from animals. The fish-emulsion fertilizers work well too. Some of these can be timed-released and then you would have to think even less about rose care.
The floribunda roses have continuous blooms and excellent disease resistance. If you live in a climate where you thought you would never be able to grow roses, give these a try. The iceberg rose was introduced in 1958 and yet it still remains to be one of the most popular roses on the planet. In terms of care and longevity, they far surpass the hybrid tea roses that you see everywhere. Don’t forget to deadhead the flowers so that your plants have production until the fall.
The iceberg rose is susceptible to some fungi, which can cause diseases that may discolor leaves or in the worst cases, lead them to drop off. You can head this off by never allowing your watering to get the foliage of the plant wet. Water the base of the plant, not the leaves or flowers. Fungal diseases can be controlled by removing all diseased branches and spraying with a natural horticultural oil.
This rose may attract spider mites, aphids and Japanese beetles. The first two can also be controlled with horticultural oil. The best way to get rid of Japanese beetles is to pick them off the plant and destroy them.
