Dwarf cannas grow to about three feet tall. They come in a variety of colors, such as the bright red Ambassador or the City of Portland, which is known for its salmon color. Regular cannas are much larger in size, so dwarf cannas tend to grow better when potted. Potted cannas will grow in almost any potting medium that can be purchased at a garden supply store--they’re really not very picky. However, it must be soil that drains well, as cannas don’t do well with soggy roots and could develop mold. You will also have to choose your container based on the size of the variety of canna you are choosing to plant. If you are not sure how large your specific canna can grow, run an online search or ask someone to help you at your garden supply store. Remember, you can plant your cannas with other plants in your container, but just remember that all of the plants in one container must have the same water and sunlight needs or else they will not do very well. Plant your rhizomes (or tubers) in these holes, making sure that each dwarf or medium rhizome is at least 1 foot (.30 m) away from the next rhizome, unless you are planting them in a container, in which case you can often fit two or three tubers in a container. If you have a larger variety of canna rhizome, make sure that there is at least 2 feet (.61 m) distance between rhizomes. Make sure that the growing points (or eyes of the tuber) or pointing up. You should water your cannas right after you plant them so that the soil will settle around them and they can start to grow. When they have begun to sprout, water your plant as much as needed, keeping an eye on the soil to make sure that it is always relatively moist (though not soaking wet). It is recommended that you bring your cannas outside so that they can get full sunlight during the warm months. If you do choose to keep them inside, make sure they are near a window that provides them with bright sunlight for most, if not all, of the day. If you did bring your cannas outside for the summer months, make sure...

考虑为种植器购买矮株美人蕉。 土壤的排水性要好，品质要好。 购买一个有排水孔的花盆。 挖10到15厘米深的洞。 给美人蕉浇水。 确保盆栽美人蕉能得到充足的阳光。 在第一次下霜之前把花盆搬到室内。
