Calla lilies require well-draining, well-draining pots that are at least 10 to 12 inches in diameter. Proper drainage is crucial for their growth and development, as improper drainage can cause rots and fungal diseases. The recommended potting soil for calla lilies is moderate to high relative humidity (RH) between 65 to 75 percent. Plant the calla lily rhizomes 1-4 inches deep with the eyes facing upward, water lightly, and place the container in a sunny spot with some afternoon shade.
Calla lilies thrive in temperatures ranging from 60-80°F during the day, but it’s important to avoid exposing them to frost. When planting calla lilies in a pot, ensure the soil has warmed up to at least a temperature of 60-80°F.
A pot size is essential for calla lilies to accommodate their root system and growth. Choose a pot that is at least 1 foot deep and wide enough to accommodate the bulbs with 2-3 inches of space on all sides. A larger pot will allow for more bulbs and more growth.
A deep container about 12 inches (30 cm) in diameter and with plenty of drainage holes is ideal for proper growth. Depending on the variety, the pots should be drenched with 1 – 3 fl oz (60 ppm) and can be repeated if the plants are beginning to develop too much.
For seedlings, aim for a pot 4-6 inches in diameter. Young plants thrive in an 8-10 inch pot, while mature calla lilies require a spacious 12-16 inch pot.
To ensure optimal growth, it’s essential to determine the right dimension of the pots based on the size of your tubers and the habit of the cultivar. Common pot sizes range from 4 to 12 inches, with larger pots accommodating more significant calla lily bulbs.

Where is the best place to put a calla lily?
Calla lily hybrids require frost-free conditions, such as a well-lit windowsill, conservatory, or heated greenhouse. Once frost has passed, they can be grown in the garden, pots, or border. They thrive in bright, well-lit spots out of the strongest midday sun. Plants should be sheltered from wind and grown from thick rhizomes or fleshy roots. To grow from dormant rhizomes, buy ready-grown plants in spring and summer and plant them 8-10 cm deep in a peat-free potting compost. Plant indoors for earlier flowers or outside after frosts. Indoor plants need to be gradually hardened off or acclimatized to the outdoors by standing out for increasing periods.
Will calla lilies bloom all summer?
The hot pink calla lily, a hybrid of the Zantedeschia plant developed by Proven Winners, has the capacity to persist for up to 12 weeks, thereby providing a prolonged period of color in containers or beds. To promote the production of additional blooms, it is recommended that container-grown plants be maintained in a potbound state. The plant attains a height of 18 to 24 inches and a width of 9 to 12 inches.
Do calla lilies like big pots?
Calla lily rhizomes thrive when planted 1 inch deep and 1 to 2 inches apart in pots at least 10 to 12 inches in diameter. Proper drainage is crucial to prevent rots and fungal diseases. The planting medium should retain moisture without being too soggy. Calla plants should be watered when the first inch or two of the soil is dry to the touch, then deeply and thoroughly. Overwatering can cause brown foliage tips. Container-grown calla lilies should be fed a general-purpose fertilizer every three to four weeks in spring and summer.
They grow best in full sun to part shade, with ideal temperatures between 60 and 75 degrees F. and nighttime temperatures not below 55 degrees F. If potted calla lilies are grown indoors, these ideal temperatures should be maintained.
Do calla lilies multiply?
Calla lilies reproduce vegetatively via the formation of growth buds on their rhizome, a process that can be readily managed in a majority of climatic conditions.
Why is my potted calla lily dying?
Root rot in Calla lilies is a common issue due to overwatering or poor drainage, which can cause fungal infections like Phytophthora or Pythium. Symptoms include yellowing leaves, wilting, a mushy or smelly root system, and overall plant health decline. To prevent root rot, use a well-draining potting mix, water only when the top inch feels dry, and remove affected parts if found. Leaf spot diseases, such as Alternaria or bacterial soft rot, can result from fungal or bacterial infections.
Do calla lilies like sun or shade?
Calla Lilies thrive in bright, indirect light, mimicking their native environment under a canopy. Too much direct sun can cause a botanical sunburn. To maintain optimal growth, observe your Calla Lily’s behavior and adjust the light exposure accordingly. As seasons change, adjust your sunlight strategy accordingly. In spring, increase light to wake your plant from its winter nap, protect it from harsh rays in summer, and consider artificial lighting in winter to keep it from dozing off. By adjusting your sunlight strategy, you can ensure your Calla Lily receives the necessary warmth and avoids the harmful effects of direct sunlight.
How much room do calla lilies need?
Calla lilies are a beautiful plant that can be grown in various ways. They require a well-drained soil, especially in containers, and should be planted about 6″ apart on center. When planting in containers, use a quality growing mix instead of garden soil. Watering is crucial for the first few leaves, then more generously once the plants have a few leaves. Overall, calla lilies are a versatile and attractive plant.
How long do calla lilies last in a pot?
Calla lilies are versatile plants that can last several weeks to a few months when grown in well-draining soil, adequate sunlight, and regular watering. Cut calla lilies can last up to two weeks if kept in a vase with fresh water and regularly trimmed. They can be planted outside in gardens, adding beauty and elegance to any setting. To thrive, calla lilies require well-drained soil, regular watering, and partial shade to full sun. They are hardy in USDA zones 8-10, but may need to be stored indoors during winter to prevent frost damage.
Do calla lilies like full sun?

Can I grow calla lily in a container?
Choose a container with drainage holes at least 10-12 inches in diameter and use an organic potting mix to fill the pot about halfway with soil. Calla Lilies are winter hardy to zone 8, so if you live in a colder region, dig them and store them in a cool, dry place. Trimming and pruning Calla is recommended, as deadheading will not re-bloom. If dividing larger clumps in warmer climates, dig them apart and use a sharp knife to replant.
If dividing smaller, overwintered pots, look for offsets in winter or early spring, cut them apart, callus, and pot them up in rich soil in the spring. Monitor and set them out in the garden when they grow.
