Space is not a problem. Container gardening can be conducted in a single pot on a table or window sill, in a more elaborate room divider, or in a built-in planter.
Just as there are many kinds of plants, there are many kinds of containers. Plants can be grown in any container that will hold a growing medium. The choice ranges from the common clay pot to cans, jars, boxes, baskets and tubs.
Most people select containers for both their practical and "esthetic qualities". These include cost, availability, weight, strength, durability, attractiveness and sentimental value.
The size and shape of the container should depend on the plant's size and shape. Tall, tapering plants are more attractive in tall, relatively narrow containers. Short, compact plants appear more at home in shallow, wide containers.
Particularly important considerations for good plant growth are the volume and depth of the container, and some provision for drainage. Containers that have drainage holes in the bottom for the removal of excess water are best. Water-right containers are difficult to manage--excess water will accumulate at the bottom of the container and injure plant roots by excluding oxygen.
Container volume and depth become important in relation to the quantity of available water and nutrients.
Besides the right kind of container, some basic requirements for plant growth must be provided. Plants need light, water, nutrients, and a satisfactory temperature ranges.
Light is the most critical requirement. The levels of all the other requirements are regulated in relation to the amount of light that plants receive. When plants don't have enough light they become tall and thin. Plants are easier to maintain in good condition when their light requirements are met.
This article is primarily about ______.
A．growing indoor plants
B．growing tropical plants
C．making containers for plants
D．choosing appropriate containers for indoor plants
they can be moved from one home to another; and they can be moved outdoors in the summer and indoors
during the cooler months.
B: Woo, that's wonderful. Besides the space is not a problem. Container gardening can be conducted in a single pot on a table or windowsill, in a more elaborate room divider, or in a built-in planter.
A: But there are so many kinds of containers and I have no ideas how to chose from them, you know, there are common clay pot to cans ,jars, boxes, baskets and tubs.
B: I hear most people select containers for both their practical and esthetic qualities. These include cost, availability, weight, strength, durability, attractiveness, and decorative and sentimental value. What's more, the size and shape of the container should be consistent with the plant's size and shape. Tail, tapering plants are more attractive in tall, relatively narrow containers. Short, compact plants appear more at home in shallow wide containers.
A: Yes, you are right. And I think those containers must have those holes in the bottom for removal of excess water are best. Water-tight containers arc difficult' to manage; excess water will accumulate at the bottom of the container and injure plant roots by excluding oxygen.
B: Those are the fundamental requirements for plant growth, but plants need light, water, nutrients and a satisfactory temperature range.
A: Yes, light is the most critical requirement. The levels of all the other requirements are adjusted in relation to the amount of light that plants receive. When plants don't have enough light, they grow slowly and become tall and thin; it becomes difficult to avoid over-watering them. Plants are easier to maintain in good condition when their light requirements are met.

A．Things plants need to grow

New York - the Melting Pot
Recently the Department of Planning of New York issued a report which laid bare a full scale of change of the city. In 1970, 18 percent of the city's population was foreign-born. By 1995, the figure had risen to 33 percent, and another 20 percent were the US-born off springs of immigrants3. So immigrants and their children now form. a majority of the city's population.
Who are these New Yorkers？ Why do they come here？ Where are they from？ (OK, time to drop the "they". I'm one of them.) The last question at least is easy to answer: we come from everywhere. In the list of the top 20 source nations of those sending immigrants to New York between 1990 and 1994 are six countries in Asia, five in the Caribbean, four in Latin America, three in Europe, plus Israel and the former Soviet Union. And when we immigrants get here we roll up our sleeves. "If you're not ready to work when you get to New York," says a friend of mine, "you'd better hit the road."
The mayor of New York once said, "Immigration continues to shape the unique character and drive the economic engine of New York City. "He believes that immigrants are at the heart of what makes New York great. In Europe, by contrast, it is much more common to hear politicians worry about the loss of "unity" that immigration brings to their societies. In the quarter century since 1970, the United States admitted about 12.5 million legal immigrants, and has absorbed them into its social structures with an ease beyond the imagination of other nations. Since these immigrants are purposeful and hard-working, they will help America to make a fresh start in the next century.
The report issued by the Department of Planning of New York
A．put forward ways to control New York's population.
B．concerned itself with the growth of New York's population.
C．studied the structure of New York's population.
D．suggested ways to increase New York's population.
