From VOA Learning English, this is the Agriculture Report.
Most kinds of rose plants come from Asia. But roses are also native to other areas including northwest Africa, Europe and the United States.
In nineteen eighty-six, the U.S. Congress chose the rose as America's national flower. Technically, Congress and President Ronald Reagan declared it the "national floral emblem." Whatever the name, the decision did not smell sweet to lovers of other flowers.
Some people say roses are difficult to grow. But you have a good chance of success if you start with a few suggestions from experts. You should plant your roses where they can get sunshine for about six hours on bright days.
You can buy roses from a garden center or by mail order. You can buy potted roses, also known as container roses, or bare-root plants. Each kind has its fans.

Some gardeners say potted roses are easier to plant. They say the roots develop better. But Jeffrey Dinslage, president of Nature Hills Nursery in Omaha, Nebraska, points out that bare-root roses come without soil. So they weigh less to transport.
The University of Illinois Extension advises getting bare-root roses as close to planting time as you can. If they arrive before you are ready to plant them, make sure the packing material is moist. Keep the plants in a cool, dark place. You plant the roses while they are dormant. The resting plants have no leaves but still need water.
When growing roses, the soil should feel moist deep down. Watering should be done in the morning. That can prevent problems called black spot and mildew.
But do not water too much. Jeffrey Dinslage says people often ask him about unhealthy discoloration on rose leaves. He says the spots are usually caused by too much water. After heavy rains or too much watering, he advises pulling away mulch temporarily from around the roots. This will help dry the soil.
In normal conditions, placing mulch around rose plants is a good idea. Mulch suppresses weeds and holds moisture in the soil. You can use mulch made from bark, pine needles, cottonseed or oak leaves.
If your soil is very dry, you can add peat or compost, which returns nutrients to the soil. If aphids, thrips or other insects invade your rose bushes, you may be able to force them off with just a strong spray of water.

参考译文
这里是美国之音慢速英语农业报道。
玫瑰的大部分品种源自亚洲，但包括非洲西北部、欧洲和美国在内的其他地区也有玫瑰。
1986年，美国国会选择了玫瑰作为国花。严格意义上讲，国会和里根总统宣布玫瑰为“国家花卉象征。”但不管叫什么名字，对其他花的支持者来说，这个决定并不那么惹人喜爱。
有人说玫瑰是很难种植。但如果你从一开始就遵从一些专家的建议，种植成功的机会很高。你应该将玫瑰种植在晴天能接收大约6个小时日照的地方。
你可以从园艺中心或通过邮购来购买玫瑰。你可以选择盆栽，或裸根玫瑰。每一种种植方法都有很多喜爱者。
有些园丁说盆栽玫瑰更容易种植。他们表示，盆栽玫瑰根系长得更好。但内布拉斯加州奥马哈市Nature Hills苗圃的负责人Jeffrey Dinslage指出，裸根玫瑰根部不带土壤，因此可以保证运输时重量比较轻。
伊利诺伊推广大学建议，购买裸根玫瑰的时间要尽可能接近你种植的时间。如果在你准备种植之前就收到裸根玫瑰，确保包装材料湿润，并保存在阴暗的地方。你应当种植处于休眠状态的玫瑰。休眠状态的植物没有叶子，但仍然需要水分。
当种植玫瑰时，土壤应该浇透。浇水应该在上午进行，这样可以防止黑斑与霉病。
但水不要浇得太多。Jeffrey Dinslage称，人们经常问他关于玫瑰叶片上的污点问题。他说这些污点通常是由于水分过多造成的。大雨或浇水过多后，他建议临时去除根部的覆盖物，这将有助于土壤变干。
通常情况下，在玫瑰周围加上覆盖物是个好主意。护根物可以抑制杂草生长，保持土壤水分。你可以使用由树皮，松针，棉籽或橡树叶制成的根护物。
如果土壤很干，可以添加向土壤中释放养分的泥炭或堆肥。如果蚜虫，牧草虫或其他昆虫侵入玫瑰花丛，可以喷水赶走它们。
