What season does the calla lily bloom?
Do you know about these? The season when calla lilies bloom and some green plant care tips related to their flowering time, let's learn about them together next.
Eye-catching calla lilies
Also known as arrowhead flower, taro, Guanyin lotus, trumpet flower, spathes taro, andDahlias, calla lilies are perennial herbaceous plants.
Calla lilies are native to the wetlands of southern Africa and prefer a warm, humid, and sunlit environment, suitable for fertile, humus-rich, and water-retaining clayey loam soil.
Calla lilies start to bloom during the Spring Festival, with March to April being the peak blooming period.
Calla lilies thrive at temperatures between 10-25°C and cannot tolerate cold. The night temperature should not be lower than 10°C.

Potting
When potting calla lilies, it is advisable to use deep pots about 20 centimeters in diameter.
The growing medium should be fertile paddy soil or a mixture of fertile garden soil, leaf mold, and sand in a ratio of 4:3:2, with a small amount of superphosphate.
After the first blooming in early spring (or in autumn), dig around the mother plant's rhizome to find the emerging bulbils.
Plant 3-4 bulbs evenly in the pot, cover with 3-4 centimeters of soil, and leave a distance of 3-4 centimeters from the soil surface to the pot opening.
After planting, press the soil down.
After planting, water thoroughly and place in a shaded area, keeping the potting soil moist.
After sprouting, move to a shaded greenhouse with scattered light for maintenance.
Watering
After calla lilies sprout, keep the potting soil moist and spray water on the leaves every day.
Watering calla lilies is not about "how often to water" or "fixed amount of water," but it increases with the number of leaves.
In general, calla lilies need frequent watering during the growing period, and early morning and evening sprays around the pot can increase humidity.
Especially when the flower stems are growing, water cannot be lacking, otherwise, it will affect the quality of the flowers.
But after flowering, as the temperature rises and growth slows down, control watering to keep the potting soil in a moist but slightly dry state.

Fertilizing
In addition to applying a base fertilizer when planting, apply a dilute liquid fertilizer every 15 days during the growing period.
The liquid fertilizer can be made from decomposed cake fertilizer.
During the peak growing season of calla lilies, apply a dilute liquid fertilizer with a mix of nitrogen, phosphorus, and potassium every 15 days.
When fertilizing, be careful not to pour fertilizer water into the leaf sheath to avoid rotting the leaves.
Stop fertilizing after flowering.
Calla lily cultivation techniques
Daily maintenance
1. Calla lilies cannot tolerate cold, and the night temperature should not be lower than 10°C. Some varieties should not be lower than 16°C.
When the temperature is above 25°C or below 5°C, calla lilies will be forced into dormancy.
2. Increasing light exposure can suppress the height of the plant's growth.
3. When the air is dry, spray water around the pot to increase humidity.
4. When the leaves are lush, thin them in time to allow the flower stems to emerge; after flowering, cut off the残花 and flower stems promptly to avoid nutrient consumption.
5. During maintenance, remove the diseased and yellowing leaves of calla lilies at any time to utilize nutrients well and maintain good ventilation.
6. It is best to wipe the leaves with a sponge or soft cloth dipped in water every 5-7 days to keep them fresh and clean.
Controlling flowering period
The key to controlling the flowering period of calla lilies lies in controlling the temperature during the growing period and adjusting the planting time.
Under normal circumstances, calla lily bulbs can bloom after 5-6 months of planting.
If the growing environment temperature can be maintained at 13-20°C, with sufficient fertilizer, suitable humidity, and light conditions, calla lilies can continuously bloom and grow without a dormant period.
For calla lilies in pots at home, as the ambient temperature drops in winter, their flowering period is also postponed.
If friends can increase the temperature of the calla lily's growing environment, it will bloom earlier.
