It blooms from November until June of the following year. If you can make sure that winter is not too cold and summer is not too hot, it can bloom all year round. In the spring, if you want to keep it blooming, you need to make sure that there is no less than 5 hours of light every day
1. Light: Calla is not resistant to strong light, and is more delicate after flowering. When giving light, avoid direct sunlight. Before and after the Spring Festival, it blooms most. The sunshine time is a little longer, but the light is not too strong. You can put it on the balcony and other bright places to receive a certain amount of sunshine. In May and June, when the sun is hot, it should be shaded to prevent it from sunburn. In winter, it should be placed in a place with good light, so as to meet the demand of flowers for sunshine and make them bloom continuously.
2. Water: it needs a lot of water during the flowering period. It can metabolize normally only when it has enough water. So, water it more often at this time. On the premise of no ponding of flower soil, properly pour more water. But in winter, water should be properly controlled to prevent it from freezing.
3. Temperature: when it's hot, put it in a windy place, spray water on the ground twice a day to help cool down, so as to avoid the problem of yellow leaves and flowers. After November, we need to increase the appropriate amount of heat preservation for it, and it is best to keep the temperature at about 20 ℃. This is more conducive to its flowering.
