Canna Lilies are one of those hardy perennials that is easy to grow and maintain.

That said, it’s important to know the invasive nature of Calla lilies before growing them at home, especially indoors.
Calla lilies are bulbs that spread by multiplying and creating other bulbs.
However, you can control the spread of this callas quite easily especially when grown in terracotta pots.
Planting calla lilies in containers to control spreading
If you want your garden to look like a floral dream, consider planting calla lilies in pots. Containers will also help to control how far it spreads out.
Although not true lilies, calla lilies do come in a variety of colors. This makes them popular as cut flowers and they also grow well in sunny window positions.
In addition to flowering for an extended period of time, calla lilies also make beautiful cut bouquets.
For best results, calla lilies should be planted in well-drained potting soil after all danger of frost has passed. To ensure proper growth, plant calla lilies in containers after the danger of frost has passed.
Planting calla lilies in containers will help them grow at a slower rate, as they won’t compete with each other for space.
Calla lilies need companion plants. Planting them near a plant that has similar root systems will promote healthy growth and reduce the likelihood of disease.
The plants will also help each other out by preventing fungal infections from developing.
Catmint is a common garden plant and is an aromatic herb. It produces clusters of lavender blue flowers during spring.
Alternatively, you can choose other companion plants such as Roses, Lavender, and Hostas.
Once you’ve chosen the right calla lilies for your container, you can start caring for them by following their basic care guidelines.
You’ll want to provide your plants with regular fertilization with a water-soluble fertilizer.
Once the blooming season is over, calla lilies need to rest for a couple of months. Resting will help them bloom better the next season. If you want to enjoy your calla lilies for many years, be sure to repot them every year.
Planting calla lilies outdoors
If you’re planning on planting your calla lilies outdoors, you should be aware of a few important things you need to know.
Calla lilies need well-drained soil and filtered light, and they thrive in ponds and containers. However, if you want to enjoy their beauty year-round, you’ll need to take extra care of your plants.
These plants require filtered light and moderate shade, and they should be planted outdoors after the danger of frost has passed.
You should plant calla lilies in early spring, after the risk of frost is gone. Plant them at least 12″ apart, 6 inches apart, and about 3″ deep.
Water them frequently, and make sure they’re planted in moderate shade. Mulch around your plants to retain moisture and keep them healthy.
Once you’ve planted your calla lilies outdoors, you’ll be surprised at how quickly they’ll grow and thrive!
To keep your calla lilies healthy, you should water them regularly. Use a liquid fertilizer that contains plenty of potash.
Fertilize your calla lilies once a month. And don’t forget to mulch them properly to help them grow.
The right mix of compost and mulch will make the difference between a happy plant and a sickly one.
You should water your calla lilies at least twice a month, depending on where you live.
You can plant calla lilies in the ground or pot them in a container and move them indoors to pots.
These plants do well in shady areas with ample ventilation.
You can also grow them in containers, which can last several years. And because they’re semi-hardy, they can survive outside and are a good choice for patios and decks. A few other tips:
Care of calla lilies
Care of calla lilies can be easy if you follow some simple guidelines. The flowering time of a calla lily varies from one day to the next, so it’s important to know when to harvest them.
You can do this at various times during the day but be sure to take note of the flower’s condition before you pull it off the plant.
Callas should be harvested when they are fully open, with stamens still visible. They require lots of light and cool weather.
A temperature of 65 to 55 degrees Fahrenheit is ideal for calla lilies. Most people keep their homes much warmer than this, so they can easily go into a dormant phase. To prevent this, mulch the soil around the bulb to keep it cool.
Remember that calla lilies can go into a dormant stage for a couple of months.
However, it doesn’t necessarily mean that the bulbs should be dug up and brought inside during this time.
Although calla lilies are perennials, they need regular watering, fertilizer, and a dormant period after flowering.
The flowers are not a good idea to bring indoors during the winter, and you should keep them in a dark place during the cold season.
You can also plant them in the ground after the danger of frost has passed. In either case, you should wait until the foliage begins to yellow before fertilizing.
Watering calla lilies is necessary for maintaining growth and giving them essential nutrients. However, be sure not to overwater hybrid calla lilies.
Do not overwater the plant, because it could lead to root rot and other diseases. The soil should remain moist but not soggy. If you notice a swollen plant, it’s time to consult your local garden center for proper care.
Diseases that can affect calla lilies
Calla lilies are susceptible to a number of diseases, including crown rot, pythium rot, gray mold, and leaf spots. Here are some of the more common ailments.
You can prevent these diseases from affecting your plants by following the steps outlined below.
To avoid any harmful effects, treat your calla lilies early. You can prevent many of them by following simple guidelines, such as avoiding overwatering.
Bacteria and viruses may attack the lower leaves of your callas and cause stem rot. This type of disease can spread to the roots.
Ring mosaic virus is another common disease that can reduce the beauty of callas and their ability to flower.
Pesticides can be used to prevent the spread of this disease. Pesticides can also be used to prevent gray mold and rhizome rot.
Excessive fertilization can damage calla lilies. In addition to causing discoloration, too much nitrogen can kill the entire plant. To avoid these issues, keep your callas in a well-draining soil. If your callas are subject to a lot of debris, such as fallen leaves and branches, they could harbor a number of pests.
In addition to these pests, weeds in proximity to calla lilies may act as host plants for aphids and thrips, which can transmit viruses.
Another major issue that can cause your calla lilies to curl is a lack of sunlight. Calla lilies naturally prefer sunlight.
They will thrive in partial shade, but lack of sunlight can cause them to wilt. If you notice curling leaves, you should repot them.
Make sure to provide them with several hours of sunlight every day. It is important to keep the soil moist for several days after repotting.
When to repot calla lilies
There are several reasons to repot calla liies, but most importantly, you’ll need to repot your calla lily once the danger of frost has passed.
If your calla lily is growing too large for its original container, repotting it is the best option for it. Using a large pot with adequate drainage will prevent root rot.
Repotting Calla lilies requires careful handling to avoid damaging the roots. Repotting your plants after last spring’s frost is essential to ensure a healthy flowering season.
Make sure not to use any fertilizer that has leaf shine, as this can cause yellow spots on the foliage. Once the new pot is in place, carefully lift the flowers and the rhizome from the old pot.
Conclusion
Although calla lilies are hardy, you should repot them as soon as the blooms fade. If you do decide to repot your calla lilies, do so in late summer or fall.
Remember, though, that you must not plant your plants in the ground during winter, as this will cause them to die.
Alternatively, you can plant them in a temperature-controlled greenhouse for the winter and replant them as soon as the last frost has passed.
If your calla lily is growing too large, you can divide it to get more flowers.
However, this method can stunt the plant’s growth, so limit the division to every 3 to 5 years.
First, wait until the foliage begins to turn brown.
Then, remove the soil and foliage from the plant. Then, slice the rhizome into sections and wait for a callus to form before replanting the calla lilies.
