Are Calla Lilies Indoor Or Outdoor Plants?

If you’re looking to bring some flair and elegance to your home, then calla lilies are the perfect choice. They are in fact indoor plants that require little maintenance and easily thrive in homes with less light (but they can also be grown outdoors).

 However, if you have pets such as dogs or cats that roam freely around your house, there’s a chance they could get into the calla lily plant by mistake. So before bringing one into your home, make sure it is child-proofed and cat-friendly!

Aside from being poisonous for animals such as dogs and cats, calla lilies are not toxic for humans either! This means that even if someone eats the leaves of this flower accidentally while handling it no harm done!

How Do I Care For Calla Lilies Indoors?

Calla lilies are easy to care for indoors. They like to be kept in a cool, dark place with good air circulation. The soil should be kept moist but not soggy and the plant should be fertilized every two weeks.

Calla lilies should be watered when the soil is dry and make sure that you keep your hands clean before handling them, as they may carry bacteria that can cause an infection if you touch your eyes or nose after handling them without washing first.

Are Calla Lilies Easy To Grow?

Calla lilies are easy to grow, and can be planted in an ordinary garden soil of sandy loam with good drainage. 

They prefer moist soil and partial shade, but will tolerate full sun if kept well watered when the weather is hot. In fact, it is best to plant them in a shady spot where they can receive dappled sunlight throughout the day.

It also helps if you water them regularly during summer months, because callas are native to marshes and boggy environments where there isn’t much rainfall. 

Having said that, if you live in an area with wet winters but dry summers then don’t worry about watering them too much their dormant period will last longer than usual anyway!

How Do I Plant A Calla Lily Plant?

Choose a pot with well-draining soil and fill it with water. The roots should be soaked for at least four hours before planting the calla lily in its new home. 

This step ensures that the plant’s roots get accustomed to the potting mix and provides them with enough moisture to survive their initial transplanting experience.

After you’ve made sure that your new calla lily is ready for transplantation, make sure you have some extra pots on hand so that you can continue to grow more flowers indoors!

How Much Water Do I Water My Calla Lily Flowers?

Calla lilies are very easy to care for indoors, but like all plants, they need water. If you are growing your calla lilies in a container or using them as indoor plants and not outside, then it’s important that you know how often to water calla lilies and when not to water them. 

Calla lily flowers will shut down if the soil is too dry or wet, so it’s important to check the soil daily before watering them again. 

You want the soil medium moist at all times during their growth cycle so they can thrive throughout spring and summer months until fall arrives when nighttime temperatures drop significantly causing flowers to die back naturally until next year’s new growth emerges again in springtime once more!

How Long Does It Take For A Calla Lily Flower To Bloom?

The length of time it takes for a calla lily to bloom depends on the variety. Some varieties will bloom in as little as 6 weeks, while others may take up to 3 years.

Calla lilies generally grow best in warm temperatures, but not extreme heat or cold. Temperatures above 100 degrees Fahrenheit (38 Celsius) can cause them to wilt and die. Temperatures below 50 degrees F (10 C) are likely to kill them as well.

Do Calla Lilies Need Sun?

Calla lilies need a lot of sun. They require at least 6 to 8 hours of direct sunlight per day, either in the morning or afternoon. 

If you live in an area where it is too hot for callas, they can grow well indoors if you give them plenty of light preferably with filtered sun through a window on the south side of your house, or under artificial lights such as fluorescent bulbs.

Are Calla Lilies Toxic To Cats Or Dogs?

The sap of the calla lily plant can cause irritation to the skin and eyes, but it’s also poisonous to cats and dogs. If you have pets that are allergic to houseplants, you should probably keep them away from your calla lilies as well. 

Calla Lillies are toxic to humans as well if ingested in large quantities. They contain calcium oxalate crystals (the same compound found in rhubarb), which causes pain and swelling when ingested by humans or animals.

How Do You Prune A Calla Lily?

You can prune a calla lily plant by cutting the stems at the base of the plant with sharp pruning shears. Do not cut more than one-third of your plant at a time, and avoid cutting off branches that are too close to other branches. 

Prune away any stems that are growing horizontally and remove browning leaves so they do not rot on your plant.

What Kind Of Soil Do You Need For Calla Lilies?

When planting your calla lilies, it is important to choose a soil that is well drained and slightly acidic. The soil should be moist but not wet, as too much water can lead to root rot. 

Additionally, the soil should be rich in organic matter (such as compost), because this will help the plant thrive.

How To Keep Calla Lilies From Getting Bugs?

Calla lilies are susceptible to a number of pests, including aphids and whiteflies. These pests can be kept under control by using insecticidal soap, pyrethrin spray or neem oil. 

Horticultural oil and dormant oil can also be used to kill off the bugs that attack calla lilies outdoors. Diatomaceous earth will keep away slugs and snails from damaging your plants.

How To Grow A Calla Lily From An Offshoot Or Rhizome?

The easiest way to grow your own calla lily is to cut the plant with at least one rooted leaf. You can do this by cutting it down to about 6 inches from its base and then planting it in a potting mix that has been enriched with organic fertilizer (such as Miracle-Gro).

Are Calla Lilies Toxic To Cats?

Calla lilies are toxic to cats, so it’s important that you keep them away from your cat if you’re growing calla lilies indoors or outdoors. If your cat ingests any part of the plant (leaves, stems, flowers or rhizomes), they can become dangerously ill and potentially fatal. 

They’re also at risk if they lick their fur after coming into contact with calla lilies and then ingest their own saliva later on. Calla lily allergies are not common in cats, but it’s still safer to avoid the plant altogether rather than risk an allergic reaction or getting poisoned by eating any part of it.

Are Calla Lilies Poisonous To Cats?

It’s important to note that calla lilies are toxic to cats. If your cat eats any part of the plant, whether it’s the flowers, leaves or stems, they could get sick. 

Even if they lick sap from a calla lily plant directly after it’s been cut back or trimmed with pruning shears, they can still become ill.

Are Calla Lilies Toxic To Dogs?

Calla lily toxicity in dogs is a serious matter. If your dog eats a calla lily, there are several symptoms that could occur: vomiting, diarrhea, excessive drooling and foaming at the mouth. There can also be other symptoms such as seizures and difficulty breathing. 

Calla lily toxicity in dogs can be treated with an antidote for this type of poisoning called “Vitamin K1”. Without treatment your dog may go into shock or suffer internal organ failure which could result in death within hours. 

It is important to know that even if you have a small cut on your hand from working with calla lilies, if your dog accidently bites you while playing they could get poisoned by licking off any juices from the injured area.

Are Calla Lilies Poisonous To Dogs?

Yes, Calla Lilies are toxic to dogs. The stems and leaves of the plant contain alkaloids which can cause severe liver damage in dogs. 

Symptoms of poisoning include vomiting, diarrhea and depression. If you suspect that your dog has eaten any part of a Calla Lily plant, contact your veterinarian immediately for treatment advice!

Are Calla Lilies Poisonous To Humans?

No. Calla lilies are not toxic to humans and don’t contain any poisonous substances that would harm people if ingested. 

However, some people may have an allergic reaction after touching the plant’s pollen or leaves because they contain allergens (proteins) that can trigger symptoms such as itching, swelling and rashes.

What Are The Symptoms Of A Calla Lily Allergy?

Calla lily allergies may be common because of their popularity as houseplants. If you suffer from a calla lily allergy, your symptoms may include:

  • Itchy eyes and nose
  • Runny nose
  • Sneezing

If you suspect that you have an allergy to calla lilies, talk to your doctor about getting tested for pollen allergies and taking steps to avoid exposure.


As you can see, calla lilies are an easy plant to grow and care for. If you want to grow them indoors or outdoors, they will do well in most conditions. They do best in full sun but will tolerate part shade as well. 

The key thing is to make sure that your soil is well-draining and does not retain water for too long after a rainstorm. If your calla lilies start turning brown at the tips of their leaves or showing signs of rot on their stems, it could be due to overwatering or poor drainage issues.
