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 1986, 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 can buy roses form 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 bare-root roses come without soil, making them weigh less to transport.

Another expert advises getting bare-foot roses as close to planting time as you can. You should plant your roses where they can get sunshine or about six hours on bright days. 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. 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.

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 grasses or leaves. If your soil is very dry, you can add soil and compost，which returns nutrients to the soil. If aphids or other insects invade your bushes, you may be able to force them off with just a strong spray of water.
