How To Grow A Potted Calla Lily?
Potted callas are not as hardy as their wild cousins. If you want to grow a potted calla, it will require careful attention.

Where Should You Grow Your Calla Lily?
Grow your potted calla in a location that gets partial sun. If you live in an area that does not get very cold during the winter months, then you can grow your plant outside if you wish. However, if you live in a colder climate, you should grow your potted callas inside.
What Kind Of Soil Should You Use?
It is best to use a well-draining potting soil when you are growing your potted callas. If you live in an area that experiences cold winters, then it is best to grow your potted callas in pots so that you can move them inside during the winter months.
How To Take Care Of Potted Calla Lilium In The Winter?
During the winter months, you need to make sure that the soil does not get too dry. Check the soil to see if it is dry, if it is, then you should water it. Keep the pot out of direct sunlight and keep it in a cool location. If your pot gets too warm, the plant could get sunburned.
How To Care For Your Potted Calla In The Summer?
During the summer months, you want to make sure that the soil stays evenly moist. Check the soil every once in a while. You can water the plant from the bottom if you wish. Callas grow from rhizomes so they will spread over time. If you do not want this to happen, then you should pot your calla in a container that is too big for it.
How Do You Fertilize Your Potted Calla?
It is best to avoid fertilizer for the first year. During the second year, you can fertilize them once per month with a water soluble fertilizer. Follow the instructions on the label for the correct amount to use. You should reduce the amount of fertilizer that you apply in subsequent years by 50% each year until you are only applying it once per season.
What Do You Need To Know About Taking Cuttings?
If you would like to share your beautiful potted calla lily with others, then you can take cuttings. Potted callas are very easy to take cuttings from. Just be sure that you do not take too many cuttings, as this could kill the parent plant.
Also, you will need to stick the cut end of the cutting into a small bit of wet sand before you put it into the rooting powder. This will help the cutting take root faster.
You can also root the potted calla in water. You will need to change the water every couple of days to prevent the roots from rotting.
What Do You Need To Know About Propagation?
One great thing about potted callas is that they are very easy to propagate. All you have to do is dig up a shoot, and then plant it in some damp soil. If you do this during the spring or summer, then it should take root within a couple of weeks. You can also divide the clumps that have become too big during this time as well.
How Do You Repot A Potted Calla?
After your potted calla has grown for a couple of years, you will need to re-pot it into a bigger container. This is very easy to do. Just remove the plant from its container, and then place some well-draining potting soil into the new container. Then, place the potted calla lily in the container and firmly pack the soil around the roots to hold them in place.
If your calla is growing in a container that is too small, then you should divide it during this time. Take clumps of the plant and remove them from the main pot.
Then plant them in their own container.
How Often Do You Water Your Potted Calla?
During the summer months, you will need to water your potted calla every couple of days. During the winter months, you can reduce this to every couple of weeks.
What Do You Need To Do If Your Potted Calla Gets Scale Insects?
If you see small insects crawling on your potted calla, then it probably has scale insects. Scales are very small insects that are hard to get rid of. The best way to get rid of them is to wash the infected plant off in the shower. Then take a cotton swab and dip it into some alcohol. Wipe off all the infected areas thoroughly. This should kill off all the scale insects. You can also use a soap and water mixture to do this as well.
How Do You Get Rid Of Slugs?
You should get rid of slugs to keep your potted calla from being eaten. You can accomplish this by placing copper foil tape around the base of the pot. This will ensure that slugs don’t crawl up the pot and eat your plant.
When you have finished taking cuttings, then you can start placing them into your rooting powder. Firmly press each cutting into the rooting powder so that half of it is covered.
Then place the tray in a warm, bright location and wait for cuttings to form roots. Cuttings should form roots in a couple of weeks.
How Do You Transplant Your Transplanted Potted Callas?
When you are ready to transplant your potted calla lily, then there are some things that you will need to consider. During the spring or summer, the best time to transplant your potted calla is in the morning. This will allow the plant a chance to get used to its new environment before the sun gets too strong.
The first thing you will need to do is select the location where you want to plant the potted calla. You should look for an area that receives full sun, but is protected from strong winds.
Next, mark out the area where you are going to dig. It should be twice as wide as the potted calla pot and about twice as deep.
Now, using a trowel, begin digging up the ground within the area that you have marked out. Try to remove large roots as you dig.
Once the ground is dug up, go over it with your hands and remove any large clumps of dirt or roots. At this point, you can add some organic material such as grass clippings, shredded paper, or decayed leaves to the top layer of the hole. Then place the potted calla into the hole. The top of the potted calla should be level with the ground around it. If it is too high, then fill in the hole around the potted calla with soil.
After placing the potted calla into the hole, firm the soil around it and make sure there are no air pockets. You can water it well to settle the soil and eliminate any air pockets.
It is important that there are no air pockets in the soil since this could cause the plant to lose nutrients and oxygen. After you have firm the soil well, then you can water it.
Finally, place a cup of organic material such as decayed leaves, coffee grinds, or grass clippings around the base of the potted calla. This will act as a mulch and prevent the growth of weeds.
What Is Pest and Disease Control?
Pest and disease control is something that every plant will have to deal with. However, potted callas are very resistant to pests and diseases. You will need to keep an eye out for the following:
Mealybugs – these insects look like tiny little ants and they move around in masses. They have a waxy looking shell which protects them from pesticides.
If you see these insects, just spray your potted calla with a strong jet of water. This will eliminate them.
Aphids – look like tiny green, pink, or black insects that move in clusters of six or eight. You can spray them with a jet of water or use an insecticidal soap to eliminate them.
You can also rub them off with your fingers since they are fairly easy to crush.
Fungus – this is one of the biggest dangers to any plant since it spreads quickly and can kill your potted calla in a couple of days. The best thing to do is to purchase a fungicide and apply it to the soil each time you water.
If you are concerned that your plant may have contracted a disease or pest, take a sample to your local garden center or nursery for diagnosis.
Taking Care of Your Potted Calla
Now that you are done with the hard work of planting and care, it is time to sit back, relax, and enjoy your potted calla! Here are some tips for caring for your potted plant:
Watering – water only when the soil in the pot dries out. If you live in a hot climate, this may mean watering it every day since the heat will dry the soil quickly.
