How to Overwinter Calla Lilies in Pots?

Calla lilies are beautiful, fragile flowers that make a great addition to any garden. However, if you live in an area with cold winters, you’ll need to take some extra steps to protect your calla lilies from the cold weather. One way to do this is to overwinter them in pots.

Here’s how: First, choose a pot that is large enough to accommodate the roots of your calla lily plant. Fill the pot with fresh potting soil and then carefully transfer the plant into the pot.

Once it’s in place, water it well. Next, find a spot for your potted calla lily where it will be protected from freezing temperatures and harsh winds. A garage or shed is a good option.

If you don’t have either of those, you can wrap the pot in bubble wrap or burlap and set it on top of something elevated like a table or chairs. Once the temperature outside starts to drop at night, bring your potted calla lily inside so it doesn’t get too cold. Keep an eye on the soil; if it starts to dry out, water it lightly but don’t overwater as this can rot the roots.

  • Start with a clean pot and fresh potting mix
  • Place the calla lily in the pot and fill it with soil, leaving an inch or two of space at the top of the pot
  • Water well to settle the soil around the roots
  • Move the pot to a cool, dark location for winter dormancy such as an unheated garage or basement
  • Keep the soil moist but not soggy during this time
  • Bring the pot back inside when new growth appears in spring and move it to a sunny spot
  • Resume regular watering at this time

What are the Best Conditions for Overwintering Calla Lilies in Pots

If you’re overwintering calla lilies (Zantedeschia aethiopica) in pots, there are a few things to keep in mind. First, make sure the pot is big enough – at least 12 inches wide and deep. Calla lilies need room to spread out, so a smaller pot will just stress them out.

Second, use a well-draining potting mix – regular garden soil will compact and stay too wet over winter, leading to root rot. A mix of 2 parts peat moss and 1 part perlite or sand is ideal. Third, water your calla lily regularly throughout the winter – they like it on the moist side, but not soggy.

If the leaves start to yellow or wilt, that’s a sign of too much or too little water. Fourth, give your calla lily some light – they won’t bloom without it. A south-facing window is ideal, but an east- or west-facing one will work in a pinch.

Just make sure the plant doesn’t get scorched by direct sun exposure. Finally, don’t forget to fertilize every couple of weeks with a balanced fertilizer – this will help your calla lily stay healthy and strong through the winter months.

How Often Should I Water My Potted Calla Lilies During the Winter

Assuming you’re referring to the Zantedeschia aethiopica, also known as the common calla lily, here are some guidelines for watering during the winter months. The frequency of watering will depend on a few factors, such as the size and type of pot, the amount of sunlight the plant is getting, and the temperature and humidity levels in your home. Generally speaking, potted calla lilies should be watered about once a week.

If your plant is in a small pot, it may need to be watered more often. A good rule of thumb is to water when the top inch or so of soil is dry. In terms of sunlight, calla lilies do best in bright indirect light.

If your plant is not getting enough light, it may need to be watered more frequently. Conversely, if it’s getting too much direct sunlight (especially in hot weather), it may need to be watered less often. Finally, keep an eye on your plant’s leaves.

If they start to droop or look wilted, that’s a sign that it needs more water. On the other hand, if the leaves are yellowing or falling off, that could mean you’re overwatering.

Is It Necessary to Fertilize Calla Lilies During the Winter Months

No, it is not necessary to fertilize calla lilies during the winter months. However, if you want to encourage growth and blooming, you can apply a general-purpose fertilizer once every month or so. Be sure to follow the directions on the package, as too much fertilizer can actually damage the plant.

What Type of Potting Mix is Best for Overwintering Calla Lilies

When it comes to overwintering calla lilies, the type of potting mix you use can make all the difference. For best results, choose a mix that is rich in organic matter and drains well. A good potting mix will also help to prevent the roots from rotting.

If you are unsure what type of mix to use, ask your local nursery or garden center for recommendations.

Should I Prune My Calla Lilies before Overwintering Them

Pruning your calla lilies before overwintering them is a good idea for several reasons. First, it will help to keep the plant healthy by removing any diseased or damaged leaves. Second, it will encourage new growth in the spring.

Finally, it will make the plant more compact and easier to store over winter.

To prune your calla lilies, simply cut off any dead or damaged leaves at the base of the plant. You can also trim back any long stems to about 6 inches (15 cm) in length.

Be sure to use sharp shears or a knife so that you don’t damage the remaining leaves.

How Can I Tell If My Potted Calla Lily is Dormant

If you’re not sure whether your calla lily is dormant or dead, there are a few things you can do to check. First, gently tug on the plant. If it comes out of the pot easily, it’s probably dead.

If it’s still firmly rooted, it’s likely dormant. Another way to check is to look at the roots. If they’re brown and mushy, the plant is most likely dead.

If they’re firm and white, it’s probably just dormant. Finally, feel the soil. If it’s dry and crumbly, that’s a good sign that the plant is dormant (since dormancy is often caused by drought conditions).

What Should I Do If My Potted Calla Lily Starts to Yellow Or Wilt

If your potted calla lily starts to yellow or wilt, there are a few things you can do to revive it. First, check the soil to see if it is dry. If so, water the plant generously and wait to see if it perks up.

If the soil is moist but the plant is still wilting, try moving it to a location with more light. If that doesn’t work, you may need to repot the plant in fresh potting mix.

How to Overwinter Calla Lilies in Pots?



If you want to keep your calla lilies blooming year after year, you’ll need to take a few extra steps to overwinter them properly. Calla lilies are native to South Africa, so they’re not used to cold winters. But with a little extra care, you can keep them thriving in pots through the winter months.

Here are a few tips for overwintering calla lilies in pots: 1. Choose a pot that’s large enough to accommodate the root system of your calla lily plant. A pot that’s too small will restrict the growth of your plant and make it more susceptible to stress and disease.

2. Use a high-quality potting mix that contains plenty of organic matter. This will help ensure good drainage and aeration around the roots of your plant. 3. Water your calla lily regularly during the growing season, but allow the top inch or two of soil to dry out between waterings.

Overwatering is one of the most common causes of death for potted plants. 4. Fertilize your calla lily every 2-3 weeks with a balanced liquid fertilizer during the growing season. Be sure to follow the directions on the fertilizer label carefully so you don’t over-fertilize and damage your plant.

5. Cut back on watering and fertilizing once fall arrives and days start getting shorter and cooler. This will help prepare your plant for its winter dormancy period.
