(11)Some people say roses are difficult to grow. But you’ll 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. Some gardeners say potted roses are easier to plant. They say the roots develop better.(12)Other gardeners point out that bare-root roses come without soil. So they weigh less to transport. However, experts advise 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. Plant the roses while they are dormant(休眠的).(13)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(霉菌). But do not water too much, because too much water may cause spots on rose leaves.(14)After heavy rains or too much watering, experts advise pulling away the covering temporarily from around the roots, which will help dry the soil.

短文最后提到,大雨或浇水过多后,专家建议临时去除根部的覆盖物,这样有助于土壤变干。既然去除覆盖物有助于使根部土壤变干,那么覆盖物的作用就是防止根部变干。
