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.

这里是美国之音慢速英语农业报道。

亚洲有很多玫瑰种植园。但是玫瑰在其他地方,包括非洲,欧洲和美国这些地方,都有本土种植的。
 
早在1986年,美国国会将玫瑰选作美国国花。严格来说,国会和罗纳德•里根总统称其为“国家花卉象征”。无论叫什么名字,这个决定并不讨其他热门爱花者的喜欢。
 
有人说玫瑰太难种植。但是如果一开始你就得到一些专家的建议,你就有机会种植成功。你应当将玫瑰种植在晴天日照长达六个小时的环境里。
 
你可以从花园中心或者网上订购玫瑰。你可以买盆栽玫瑰,也叫做容器玫瑰,或者裸根植物。每一个品种都有它的喜爱者。
 
一些园丁说,盆栽玫瑰比较好种植。他们说玫瑰的根部长得更快。但是内布拉斯加州奥马哈市“自然山苗圃”的董事长杰弗里•汀斯雷芝指出,裸根玫瑰是不带土的,因此他们的运输较轻。
 
伊利诺斯州大学分校建议尽可能在靠近种植时间买裸根玫瑰。如果你在准备好种植前就收到玫瑰,确保他们的材料是干燥的。将植物放在阴冷,黑暗的地方。在他们处于休眠期的时候种植。休眠期的植物虽然没有叶子,但是也需要水。
 
种植玫瑰时,土壤应该是充分湿润的。浇水应该在早上。这样可以避免黑斑病和霉菌。
 
但是不要浇太多的水。杰弗里•汀斯雷说人们经常问他关于玫瑰叶子上不健康斑点的原因。他说这些斑点通常是由太多水分造成的。他建议大雨过后或者浇太多水之后,把覆在根部的覆盖物暂时拿掉。这能够使泥土更快变干。
 
一般情况,在玫瑰四周多放一点土是个好主意。这个覆盖物抑制杂草的生长,并保持土壤中的水分。你可以用树皮,松针,棉籽叶或橡树叶做的根护物。
 
如果你的泥土非常干,你可以加一点泥炭或肥料,这些能汇入土壤中的营养。如果蚜虫,牧草虫和其他昆虫入侵你的玫瑰丛,你只需要用水大力喷射就能将它们赶走。
