Growth habits of calla lilies

Calla lilies native to southern Africa, often born in rivers or marshes, like warm climate, not cold-resistant, not resistant to high temperature, the suitable temperature for growth is about 20 ℃, the rhizome will be frozen to death at 0 ℃, sufficient sunshine in winter, lack of light, less flowers, slightly shady, appropriate shade when the summer sun is too strong and hot, like humidity, a little stagnant water does not affect growth, but not tolerant to drought The dormancy period of loam soil, which is loose and fertile and rich in humus, varies with different regions. When cultivated in the Yangtze River Basin and the north of China, it is appropriate to move into the greenhouse in winter, blossom in winter and spring, dormancy in summer due to high temperature and drought, and not dormancy throughout the year in subtropical regions that are not cold in winter and not dry and hot in summer.

How to make calla lilies bloom all the year round

1. Turn the basin and change the soil: in order for calla lilies to have flowers all the year round, the pot should be turned twice a year, and a larger basin should be selected to maintain a sufficient nutritional area. the first turning of the basin should be carried out after the winter flowers bloomed in early April, and the second time after the Beginning of Autumn. If the rhizome has been covered with the whole basin, ramet must be carried out, each plant should not exceed 3 leaf clumps, the culture soil should be loose and breathable and have a certain water retention capacity, and adequate bottom fertilizer should be applied. To ensure a lasting supply of nutrition.

2. Cool maintenance: for most of the spring, summer and autumn except dog days, calla lilies should be kept in the shade, not directly in the sun or completely cool. Water should be sprayed to the ground frequently before the rainy season to increase air humidity. The basin soil should be kept moist and should not be dry. Thin liquid fertilizer should be applied every 10 to 12 days and moved indoors in mid-October. More sunshine can be seen later. Pay attention to ventilation. To prevent the occurrence of diseases and pests.

3. Timely pruning: the life span of calla lily leaves is short, and the outer old leaves begin to turn yellow after the new leaves grow. The yellow leaves should be cut off in time, and the residual flowers and flowers should also be cut off in time, otherwise nutrients will be consumed because of fruiting and affect later flowering. Do not spray on the plant when watering to prevent the pruning place from rotting and infecting the whole plant.

4. Keep warm and humid: the maintenance of midsummer and cold winter is the key to whether calla can blossom all the year round. In mid-July in midsummer, the potted plant should be moved to a place with wind, preferably all shaded. Spray water to the ground at noon and afternoon for 2 to 3 times to prevent heat and cool down. If the maximum temperature during the day does not exceed 30 ℃, you can continue to bloom. Winter room temperature should be 16 ℃ to 18 ℃, and the minimum should not be less than 8 ℃, such as indoor air drying. Water should be sprayed around to moisturize the leaves to prevent the yellow edge of the leaves, and the light should be increased to make them blossom continuously in winter.
