People have been growing chrysanthemums（菊花）for more than 2,000 years. Mums make bright and colorful gardens. People in China and other Asian cultures make tea with the flowers.
One basic kind of mum is the garden mum. The other basic kind is the florist mum. The garden mum is better able to handle different growing conditions.
There are many varieties of mums. The decorative mum is often seen in gardens. Another popular type, the quill mum, has long, straight petals（花瓣）like a tube or needle.
Chrysanthemum blooms can be white, yellow, gold, red or other colors. The plants often grow one meter high.
The soil for chrysanthemums should be kept moist but well drained so it does not get too wet.
Newly-planted mums should be watered two or three times a week, depending on conditions. Plants established in the ground may do well just with normal rainfall.
Mums grow best in full sunshine. They produce colorful blooms when days get shorter and nights get longer. The life cycle of the plant depends on the amount of daylight. This is why experts advise against placing mums near night lights or street lights. The light may interfere with their normal growth cycle. The plants may develop buds too soon.
In climates where temperatures fall below freezing, plant mums at least six weeks before the first frost. That way, the plants will be well established for cold weather.
Some gardeners say the most beautiful presentation comes from planting mums close together. But be sure to leave enough space to let air flow between the plants. If not, there may be a greater chance of disease.
To get more blooms, gardeners pinch（掐）back the branches when new growth has reached fifteen centimeters. Squeeze about five to seven centimeters off each branch. Pinch it again when a branch grows another twelve to fifteen centimeters. Stop the pinching about one hundred days before you want the plants to bloom.

The beet (甜菜) is a tasty root vegetable that does not require much work to grow. People think of beets as being always dark red，but they can also be pink，yellow or white. Beets are high in nutrients，and both the root and the tops can be eaten. The leaves make good salads when the plants are young，and the greens can be cooked when the plants are older. Beets grow best in full sun and in loose soil that is not too wet.
Remove stones from the soil while preparing the ground，and test it before adding fertilizer Beet seeds can be planted as soon as the soil can be worked at the start of the growing season. Planting them every two or three weeks will provide a continuous harvest into the fall. A beet seed is a fruit containing several seeds. Overcrowding the plants will mean that the roots cannot spread out and grow，so thin the beets by removing the smaller ones and using them as greens.
A specialist named Cindy Haynes says little or no fertilizer is needed in rich soils. Once the seeds are planted，however，she suggests covering the soil to protect it from the rain and during dry periods. She also suggests putting a fence around the plants to keep away rabbits and deer. She says the only work beets need once they have been thinned is weeding and， when the weather is dry，a weekly watering. For best results，beets should be picked when the roots are two and one-half centimeters around. Larger beets can be tough，and have to be cooked for a long time. Beets can be eaten in many ways.

Trees are useful to man in three important ways: they give him wood and other useful things, they give him cool places, and they help to stop drought and flood.Unluckily, in many parts of the world, man has not found that the third of these points is the most important. Man wants to make money from trees, so he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And also, he is usually too careless to plant and look after new trees. So the forests slowly disappear. This does not only mean that man will have fewer trees.

The results are even worse: for where there are trees, their roots break up soil-make the rain in-and also bind the soil, thus stopping it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing is left but useless desert.
