How to make calla bloom more in summer

Calla lily grows at a suitable temperature of 10 ° C to 25 ° C. From March to October each year, if the temperature can be controlled at about 20 ° C and the relative humidity is 85%, flowers can be produced during this period. The key to making calla bloom more in summer is shading, cooling and humidification.

When the sun is too strong in summer, if no measures are taken to avoid strong light, calla leaves will turn yellow or wither. To maintain sufficient moisture, it is advisable to spray clear water on the ground near calla in the morning, midnight and night to increase air humidity. The pot soil can be made up of loam soil, humus soil, and coarse sand, plus bone meal, manure, and superphosphate. During the growth period, it is advisable to topdress the fertilizer once every half a month. Do not pour fertilizer into the petiole. When the vegetative growth is too strong, the leaves should be thinned in time to facilitate the stalk extraction. By doing this, you can make calla bloom more in summer.
