This is the VOA Special English Agriculture Report.
People have grown chrysanthemums2 for more than two thousand years. Chinese and other Asian cultures make tea with the flowers. But mums also make bright and colorful gardens.
One basic kind of mum is the hardy3 or garden mum. The other basic kind is the florist4 mum. The garden mum is better able to handle different growing conditions than the florist mum.
There are many varieties of mums. The decorative5 mum is often seen in gardens. Another popular type, the quill6 mum, has long, straight petals7 like a tube or needle.
Chrysanthemum1 blooms can be white, yellow, gold, red or other colors. The plants often grow to one meter in height.
The soil 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. In dry conditions they will need more water.
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 nightlights or streetlights. The light may interfere8 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 is expected. That way, the plants will be well established for cold weather.
Placing mulch around the plants can protect them from the cold. Doug Akers from the cooperative extension service at Purdue University in Indiana suggests straw or shredded9 leaves for the mulch. The material will also add nutrients10 to the soil.
Some gardeners say the most beautiful presentation comes from planting mums close together. But they also advise leaving enough space between the plants so air can flow. If not, the chance of disease may increase.
To get more blooms, gardeners pinch back the branches when new growth has extended to fifteen centimeters. Squeeze about five to seven centimeters off each branch. Pinch again when a branch grows another twelve to fifteen centimeters. Stop pinching about one hundred days before you want the plants to bloom.
