There are plenty of viable ways to supply your Calla lily with water. If you grow your plant in an indoor pot, for the Calla lilys in small pots, you can bring your potted plant to your kitchen sink. Then, use the faucet to add water to the container. By holding the pot in your hands, you should easily notice when the water begins to run through the pot’s drainage holes, at which point you can stop watering. The cold temperature will hurt the plants' root system, so please don't do this during winter or in cold climates. Most of the time, watering via your faucet is permissible for the Calla lily. However, if the local tap water contains a high proportion of fluorine, chlorine or salts, you should consider using rainwater or lake water. Also, since the Calla lily can respond well to overhead watering and watering directly into the soil, you can use a watering can, hose, or just about any tool you’d like to water it.

If you discover that you have underwatered your Calla lily, your first step towards remedying the situation is to give your plant some water. Water deeply until excess water runs from the container’s drainage hole, or if you grow outside, water until the soil has become entirely moist. If you find your Calla lily is receiving too much water, begin by reducing your watering schedule. You also want to address the soil and container your Calla lily grows in. If either the soil or the container makes it difficult for water to drain efficiently, your plant will likely become overwatered again. Resolve the issue by moving your plant to looser soils and/or a container with bigger drainage holes or a more porous material. Also check the location of the plant. If the plant is in places like a corner, then it is recommended to move it to a window or around a door to enhance ventilation. Making sure the plants are in a well-ventilated location can reduce the occurrence of overwatering to some extent.

The Calla lily is not a species that requires consistent soil moisture. Instead, it is better to allow this plant’s soil to become dry between waterings. If you are like the many gardeners who grow Calla lilys in containers, you can judge whether or not it is time to add water by how dry the soil within the container is. For instance, if about top half of the soil in your container has become dry, it is time to add water. You can feel it by inserting your fingers or sticks into the soil or with soil moisture meter. For those who grow the Calla lily outdoors, you can plan to do your watering about once every other week, provided it has not rained recently.

After waiting for the first several layers of soil surrounding your Calla lily’s root to become dry（top half of the soil）, it is time to add enough water to make them moist again. The amount of water it takes to achieve that goal depends on if you use a container, how large that container is, and how large your plant itself is. For a small Calla lily growing in a small to a medium-sized container, one to two cups may be enough to dampen the soil sufficiently. As you would expect, the volume of water you supply should increase for a larger plant. The best way to make sure your plant has received enough water is to stick your finger or a trowel into the soil and feel whether it is entirely moist. Alternatively, you can water until you see excess water draining from the holes at the bottom of your container.

Overwatering and underwatering are both bad for the health of your Calla lily. These two issues also manifest themselves in subtly different ways when they occur. Calla lily that receives too little water may begin to develop yellow leaves. Underwatering may also cause the leaf margins to become brown and brittle. By contrast, Calla lily that gets overwatered will often show yellow and brown marks on its leaves at the same time. Overwatering can also lead to diseases like root rot, some of which may also be visible on your plant. However, if you know the signs of overwatering and underwatering, you stand a good chance of correcting both issues.

During spring and fall, your watering schedule for the Calla lily will remain relatively the same, which will involve watering this plant about once every week. During summer, you may find that the hot weather causes your plant to need more water than usual, especially if it grows where there is a considerable amount of daily light exposure. In the winter, if it's hard to find some warm places for you plant, your Calla lily will enter a dormant growth phase, in which it will need far less water than usual. At this time, you may get by without watering your plant at all. If you do choose to water during winter, you should not do so more often than once every two to three weeks.

After planting a new, young Calla lily or after transplanting an older Calla lily, you will probably need to give this plant more water than usual. Young plants often need consistent soil moisture during the early stages of their growth to help them adapt to their new growing locations. Transplants also need more water for a brief time to overcome transplant shock. In either case, you may need to water multiple times per week until your plant has exhibited continuous healthy growth. In most situations, your water should be moderate and should never be significant enough to cause overwatering.

There are a few reasons why you may need to water an indoor Calla lily more often than one that grows in the ground outdoors. First, indoor growing settings tend to be drier than outdoor ones, often due to the effect of air conditioning units. While thw size of the pot and the soil determines the warer accumulating ability. Additionally, when your plant grows indoors, it will rely on you entirely for its water By contrast, Calla lily that grows outside can receive water from rain. If you are in an area with high rainfall, you may not have to give it extra watering. When there is not enough rain, you should water additionally to ensure that the soil does not dry out completely.

The usual goal for the Calla lily is to have it grow as big and full as possible. While the plant doesn’t require consistent trimming, it can benefit by removing old flowers and any damaged, dead, or diseased leaves. You can also trim back the leaves if it is starting to get too big for the pot and space you are keeping it.

Calla lily don’t have a winter dormancy cycle at the suitable temperature. With that said, their growth does slow down as the days get shorter, however the leaves don’t die. What does that mean for pruning? It means there’s no specific season where it’s better to prune. Ideally, you will want to wait until the flower blooms before pruning it, which can take about a month after the appearance of the blossom. With deadheading, you’ll want to do this around late spring or when only a few of the blossoms have faded. You should always prune brown or yellow leaves when you notice them. Throughout the growing phase, make sure to pay close attention to any potential diseased leaves and remove these as necessary.

Once you’ve pruned your plant, you should dispose of the stems and leaves either by composting the healthy ones or throwing out the diseased parts. You can also fertilize just before or after pruning, which gives Calla lily a little vitamin boost that can provide it the nutrients needed to better protect itself from any nearby pathogens or diseases. You don’t need much after care when you’re done pruning. It might benefit from light watering and some liquid plant food to encourage new blooms and growth.

Chances are you’re not getting the Calla lily from seed, which means you’re already getting a mature plant. Since the plant doesn’t have a true dormancy cycle, there are really only two phases: blooming and non-blooming. While the plant is blooming, you should only remove yellow or dead leaves and cut off any brown tips on the leaves. Avoid doing too much pruning during this time as it can stress the plant. Still, you should remove any diseased or dead leaves to keep your plant presentable. The best time to prune is after the blossoms have already wilted. You can remove both the spent blossoms and any old and yellowed leaves at the same time. If you’re noticing a large amount of yellow leaves, you might be overwatering your plant or not giving it enough nutrients. While yellow or brown leaves don’t always mean there’s an issue, if you notice a large amount of leaves shifting colors, it usually means there’s a problem with the plant.

As an evergreen plant, Calla lily doesn’t have the same cycles as those found in colder areas. The leaves will remain green throughout the year, which is one of the many reasons it is a popular houseplant. If you want to deadhead, you should do so after the blossoms have already wilted. Throughout the growing phase, make sure to pay close attention to any potential diseased leaves and remove these as necessary.

How you prune the Calla lily will depend on whether you’re performing general care or deadheading. For general care, simply cut off the blossoms that have already died. Make sure to get as close to the base as possible and snip at a 45-degree angle. Repeat this for all stalks with wilting blooms. After that, trim back any outer leaves that are old and yellowing. If you simply want to thin the plant out, start with the outermost leaf and work your way in. Avoid removing more than 30 percent of the leaves at once. Throughout the growing phase, make sure to pay close attention to any potential diseased leaves and remove these as necessary.

Calla lily typically needs full, indirect sunlight in order to thrive indoors. This means that the plant should be exposed to bright sunlight that doesn’t hit it directly from a window or another light source, like a grow light. You can easily protect it from direct sunlight by placing a sheer curtain between your Calla lily and the window, or by placing it behind a part of the window with a dark screen.

If this is your first time bringing your Calla lily home, then it might be a good idea to try to ease it into the sunlight it needs, rather than place it in bright, indirect light right away. Over the course of two weeks or so, you can slowly move your plant into the sunlight to avoid shock or burning of the leaves from sudden intense light exposure. By easing it into the light, your Calla lily is much more likely to adapt to your home environment well.

Calla lily is one that can easily sunburn with too much sunlight. In the wild, these plants only receive mild, dappled light, filtered down from tree canopies. While they need more light than that to grow in our homes, too much can certainly cause issues. If your Calla lily is getting too much light, you’ll notice that the foliage begins to look bleached or washed out, the tips of leaves may turn yellow or brown and crispy, and it may even grow too quickly to support itself.

Sunburn for plants is much less severe than sunburn for people. While it may look unsightly, crispy, burnt leaves can be removed if they’re too far damaged to recover, or over half of the leaf is damaged. However, you can also try trimming back the leaves just to remove any sunburn damage in an effort to save them, if there’s not too much discoloration. Move your Calla lily away from its light source to avoid future light damage.

While some plants may be ready to face the sweltering sun straight out of the ground, Calla lily needs some time to build itself up enough to tolerate bright light. Propagated cuttings should receive only moderate indirect light, while new leaves during the growing season should be shielded a bit as well. The tender new leaves are more prone to sunburn than any other part of the plant.

Fortunately, plants can communicate in their own language to convey whether they have adequate sunlight or not. Like most plants, your Calla lily will tell you if it isn’t getting enough sunlight. The most visible sign is when your plant becomes particularly dark, or there is no new growth on the plant from one season to the next. You’ll also notice that leaves that do grow in may remain smaller than others, since there isn’t enough light to photosynthesize to support large new leaves.

Depending on how bright the sunlight is that your Calla lily gets, the number of hours in a day may vary. If you have your plant in bright, indirect light, then there’s no need to try to restrict or increase the amount of time your plant gets this light each day. However, if light is less bright or further away from your Calla lily, then you can try to aim for at least eight hours of full light per day.

For this tropical plant to thrive, you’ll want to keep them between 75℉ and 90℉ (25-32℃). Each species can handle temperatures outside of this range, but keeping it within several degrees of these limits will ensure they grow to their maximum potential. As for its extreme temperature limits, any environment below 50℉ (10℃) or above 95℉ (35℃) will begin to hinder its growth and cause various aberrations to its leaves and stems. This is especially true with low temperatures; even a light frost can cause your tropical plants to perish. Cellular death can begin to happen at a rapid pace, with some species dying in as little as 12 to 24 hours.

While Calla lily doesn’t require any changes in temperature to enter different growing phases, it is important to stay consistent. Wild temperature fluctuations can slow down its growth regardless of its current phase, so it's always better to keep them in a controlled environment. That optimal temperature range of 75℉ and 90℉ (25-32℃) is vital to maintain, especially staying above the lower limit. Going above 90℉(32℃) isn’t ideal, but as tropical plant it won’t suffer too much. On the other hand, going below 50℉ (10℃) (and especially 40℉/5℃) will begin to directly damage this heat-loving plant species.

Calla lily does not need different temperatures for different growing seasons. The most important step in seasonal care is to keep the environment within the optimal temperature range. That's why it's always best to keep this plant indoors. That way, you can control the temperature no matter what the climate is like outside. Light is also important for tropical species, with all of these plants preferring a partial side level of sun exposure. This means any light they receive needs to be dappled or filtered, with bright but indirect light being the best option when growing your plants indoors. Too much direct sunlight can negatively affect your plant’s leaves, reducing its growth potential.

Tip #1: Don’t Leave Your Plant Near Windows in Colder Months If you want to make sure your plant isn’t exposed to colder temperatures, you may want to keep them away from windows. In colder months like late fall and winter, even the smallest draft can leak cold air into your home through cracks in your windows. While this air usually dissipates and warms up as it travels throughout your home, any plants placed in close proximity to the window will be affected. Move your tropical plants into an area where they will still get bright but indirect light, while making sure they won’t be affected by potential drafts. Tip #2: If You Find Dry Patches, Your Plant May Be Getting Too Much Sunlight or Heat You may notice the leaves become white or even scorched on a sunny day. These discolorations and unusual markings usually indicate that a plant is getting too much heat or sunlight, and it may be dehydrated. Excess light and heat will dry out the soil, stopping plants from getting the moisture they need to support their cellular structure. It also slows down or stops the process of photosynthesis, further hindering growth. If ignored for too long, these dry spots can spread and eventually result in the death of your plants. Tip #3: Avoid Frost at All Costs Colder temperatures and frost can damage your plants by causing ice crystals or disrupt normal physiological activity. This makes it nearly impossible for water to move freely throughout plant tissue, creating a deficit of moisture in their stems and leaves. You can tell a plant has been damaged by frost if it begins to suffer from hydrosis (it will appear as though it's soaked with water.) If the problem persists, your plants may begin shriveling and turning a dark brown or black hue. After that, the plant will almost certainly die.

The best way to maintain the right temperature range for Calla lily is by keeping an eye on both the climate and humidity. You’ll want to try to keep each species in a room where you have access to climate control, keeping the heat in the temperature range best mimics its natural habitat. The humidity levels will also have a direct effect on temperature, so it's important to monitor these as well. You can artificially raise the humidity of your growing space by using a humidifier or lightly misting the leaves with water. If you intend to grow this species outside, you may find it difficult to maintain the right balance of temperature and humidity. If temperatures begin to drop or the air becomes too dry, your best option is to find room within your home and move your plant inside. An indoor growing space will allow you to control the climate more closely, helping your plant reach its full potential.

Fertilizer, and soil nutrients in general, are an essential form of fuel that your Calla lily will use to maintain healthy growth. In general, plants use the nutrients they find in the soil to develop new plant material and keep their existing components in good condition. For the Calla lily specifically, fertilization is necessary to help this plant display the best version of its flowers. Since the flowers are the main form of attraction to this plant, most gardeners will want to do all they can to ensure the flowers appear in their best form. Fertilization is one of the most reliable ways to help your Calla lily produce the best possible blooms.

The Calla lily goes through two main phases throughout each year. The first phase is the dormant phase, in which this plant will put forth minimal new growth. This dormant phase takes place during the winter. The other phase is the active growth phase, which takes place during spring and fall, which is when your Calla lily will need fertilization the most. Generally, it is best to fertilize your Calla lily starting in the spring months. You should repeat the feeding about once per month throughout the rest of the spring and through most of the summer. As fall approaches, you can begin to reduce your fertilization rate.

You want to support Calla lily growth, but you also don’t want to cause root burn. Your plant is actively growing in the spring and summer, it’s when the extra nutrients are necessary. In the fall and winter, your plant will enter its dormancy stage. It’s when you want to stop fertilizing.

The ideal fertilizer for a Calla lily is one that has a relatively balanced mix of the three main plant nutrients, with slightly higher amounts of phosphorus. Alternatively, some gardeners choose to improve their Calla lily 's soil by adding organic materials such as compost, worm castings, and manure. Fertilizers can come in many forms, and most of these forms will work well for your Calla lily. However, some of the best fertilizers for Calla lily come in either a liquid or a powdered form. Regardless of which you use, you should ensure that you dilute your fertilizer and apply it while watering your Calla lily.

Once you have found a suitable fertilizer and learned the ideal fertilization schedule for your Calla lily, you are ready to learn how to apply your fertilizer. When feeding your Calla lily, the most reliable method is to mix your liquid fertilizer with water before applying it to the soil. Each fertilizer may have different directions on how to feed your plants. Usually, it is best to follow the manufacturer's guidance on how to use the fertilizer they produce. These instructions should include information on how to properly dilute the fertilizer to prevent overfertilization. Mixing your fertilizer in water is an easy process, and once it is complete, all you need to do is pour the mixture into the soil where your Calla lily lives.

Overfertilization is something that you should consider when caring for any plant, but it is especially important when growing a Calla lily. A Calla lily, when overfertilized, will show clear signs of distress, which, at times, may be so serious that they lead to the death of your plant. Overfertilized Calla lily will likely show leaf discoloration as well, including browning. In the worst-case scenarios, excessive fertilization will draw moisture out of your plant's roots, which can cause it to decline quickly.
