How does calla lily potted and conserved?

Zantedeschia, commonly known as the calla lily, is a versatile plant that serves both as an ornamental foliage and a popular cut flower. When cultivating it in pots, it's essential to use well-draining sandy loam soil and apply sufficient basal fertilizer before planting. For the best results, mix fully decomposed organic matter such as cake meal and pig manure into the soil to provide a rich foundation for growth.
After the first bloom in early spring or autumn, small shoot buds will emerge around the rhizomes of the mother plant. These should be carefully removed and planted individually in new pots. Once transplanted, water thoroughly and place the pots in a shaded area, keeping the soil consistently moist. Once new growth appears, move the plants to a partially shaded location with indirect light—avoiding direct sunlight or full shade.
During the growing season, apply liquid fertilizer every 20 days. A mixture of decomposed cake meal and balanced fertilizer works well. Additionally, you can supplement with a diluted NPK solution every 10 days for extra nourishment. Be careful not to pour fertilizer directly into the leaf sheaths, as this may lead to root rot.
Watering is crucial during the growing period. Mist the ground around the pots in the morning and evening to maintain humidity. To keep the leaves clean and healthy, gently wipe them with a damp sponge once every 5-7 days. When the foliage becomes dense, remove older leaves to make way for better pedicel development.
Calla lilies typically bloom from March through May. After flowering, promptly remove spent blooms and buds to conserve energy for future growth. If left unattended, the plant may waste nutrients on seed production.
From May to July, the plant enters a dormant phase. During this time, reduce watering and create a drier environment. Once the leaves turn completely yellow, carefully dig up the bulbs, allow them to dry slightly, and store them in a cool, well-ventilated place until fall planting.
If you prefer to keep the plant actively growing, you can move it into a shaded, well-ventilated area in late June. Mist the plants 2–3 times daily during the hottest hours to lower the temperature. As long as daytime temperatures stay below 30°C, the calla lily can continue blooming throughout the summer.
Before the cold dew season in October, bring the plants indoors and limit watering. Keep the room temperature above 10°C. Wash the leaves weekly with lukewarm water to keep them fresh and vibrant. In dry conditions, mist the air around the plants to increase humidity. Ensure adequate lighting during winter to support continued health.
To encourage early spring blooms, apply a diluted liquid fertilizer 1–2 times in December. This will help the plant prepare for its next flowering cycle.
During the growing season, poor ventilation can lead to aphid infestations. If pests appear, spray a 1500–2000 dilution of 40% omethoate and improve air circulation immediately to prevent further damage.
