There are plenty of viable ways to supply your Floating arum with water. If you grow your plant in an indoor pot, for the Floating arums 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 Floating arum. 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 Floating arum 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 Floating arum, 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 Floating arum is receiving too much water, begin by reducing your watering schedule. You also want to address the soil and container your Floating arum 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 Floating arum 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 Floating arums 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 Floating arum 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 Floating arum’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 Floating arum 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 Floating arum. These two issues also manifest themselves in subtly different ways when they occur. Floating arum 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, Floating arum 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 Floating arum 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 Floating arum 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 Floating arum or after transplanting an older Floating arum, 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 Floating arum 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, Floating arum 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.

You can prune your Floating arum any time you notice dead, diseased, or damaged leaves during the growing season. Once you notice such a leave, locate an unwanted leaf, then follow its stem all the way to the bottom of petiole. Removing dead stems will increase the light and ventilation of the plant and help it to grow. You can cut its stem just above the soil’s surface to remove it. Such pruning can take place as needed during spring and summer. Also, this plant can bloom any time between spring and fall, and some gardeners choose to remove flower buds before they have a chance to open. Removing unopened flower buds allows this plant to focus most of its growing energy on its beautiful leaves. However, pruning in this manner does not necessarily influence the plant’s overall health. Cutting back should be done late in the winter to early spring. Ideally, you should wait until you see new basal growth before you cut off the dead and dried winter parts, to about 6 inches from the ground.

Pruning the Floating arum is as easy as waiting until you notice dead or damaged leaves on your plant. When you recognize these leaves, equip yourself with a pair of sharp and sterile hand pruning shears. Hand pruning shears will work best as larger tools like loppers will not be well suited to the precise cuts you need to make. Once you have a proper set of pruning tools, locate an unwanted leaf, then follow its stem all the way to the bottom of petiole. Removing dead stems will increase the light and ventilation of the plant and help it to grow. Cut the stem just above where it exits the soil to remove it entirely. If you wish to stop this plant from flowering, you can use the same pruning shears to remove any buds before they open. Finally, you may prefer to just trim off dead or damaged portions of the plant, including deadheading spent flowers, to keep it looking its best. This can be done at any time of year. Diseased or damaged stems should be cut right at the soil line and removed completely. Blooms should be cut off just below the flower head. Cutting back should be done late in the winter to early spring. Ideally, you should wait until you see new basal growth before you cut off the dead and dried winter parts to about 6 inches from the ground.

All that is required of you once you have pruned your Floating arum is to clean up. Once you have pruned, deadheaded, or cut back your Floating arum, gather the bits you have cut off and discard them. If there are any diseased parts of the plant that you have pruned away, do not discard them with the rest of the pruned pieces. Diseased foliage should be disposed of. When watering after pruning, be careful not to touch the wound to prevent fungus from infecting the plant through the fresh wound. Placing Floating arum in a well-ventilated location will also help the wound to dry out and heal in time.

For your major pruning, use sharp pruning sheers that will make clean cuts to avoid damaging your plants. As you are pruning your Floating arum, step back occasionally to check the appearance of the plant to make sure it has the shape you want and that you are pruning it symmetricaly. It is recommended that gloves and safety glasses be worn while pruning Floating arum.

Pruning is an important part of plant care and maintenance. Different plants have different pruning requirements. Some plants may need little to no pruning, while others may require more specific attention. Most plants should be pruned to remove damaged or unhealthy foliage. Other plants may be pruned to control their shape and size. Pruning may even be done to remove the flower heads of plants and stop them from self-seeding. Although some gardeners may find pruning a tedious task, it is a necessary evil and is an essential part of keeping your plants happy and healthy.

Floating arum requires about 6 hours of direct and continuous sunlight daily. These are desirable to help them grow healthily, and this will help them grow faster. You might also want to provide these species with supplemental light during the winter with the help of lamps. The species need several hours of unobstructed sunlight to have vibrant foliage, so you might want to place them in the brightest areas of your garden or indoor nursery.

They are suited to a full sun and don't tend to tolerate shady areas. It's best to have at least 8 inches of space for each plant especially if you’re planting a lot of them so each can get a lot of sunlight. Generally, the Floating arum has a high demand for direct, full, and abundant sunlight. During summers, you can place them outside in the morning sun, so they will have enough light to grow. They don't do well with partial sunlight and don't tolerate filtered or part shade. They might also not grow well when a huge tree constantly provides shade, so plant them in areas without obstruction.

The Floating arum should never avoid sun exposure because they seek and love the bright light. They love the sun so much that they require at least 6 hours of exposure regardless of the climate. Some areas, especially during the fall and spring, don't need protection because they require full sunlight. However, if you're located in a tropical climate or if the summer sun is too much, it's always possible to transfer the potted species inside until the temperature cools down again. Overall, you don't need to plant them near buildings, tall trees, and other structures because they need full sun for at least 6 hours.

If there's insufficient light, the Floating arum will not thrive. This is going to result in poor growth. Fungi and bacteria can feed on the plants' tissues, which are generally common for the plants grown in shady areas. When the plants receive too little sunlight, they tend to become spindly. They will have weaker stems because they are constantly seeking to receive light, and this can result in wilting or brown leaves. You might want to see if there are insects present or a rhizome rot in Floating arum as this can be another sign that they are not receiving enough sunlight. If this is the case, put them in another area where they will receive bright and direct light to see if it will make a difference.

During their growing phase, you need to expose the plants to the sun so that they don't have to stretch and grow upwards. You can avoid the process of etiolation and prevent the stems of Floating arum from growing weak. This is generally prevalent for those that are receiving no sun or are in a partially shaded area when they are young. When they are already established and have matured, you also need to continuously expose them to a full sun because they need photosynthesis to grow more. When they are placed inside a greenhouse or a nursery for a very long time, and you decide to transfer them into a garden, you need to gradually introduce them to the bright lights. Still, you should never suddenly place them in direct heat, especially if it's mid-afternoon. They need a period to adapt and to become used to the intensity of sunlight in your area, so give them some much-needed time.

As mentioned, the Floating arum needs 6 to 7 hours of direct sunlight to do the process of photosynthesis. This helps them produce enough food to grow. You can make this easier for yourself when you group them together and plant them in the same spot in your garden. This way, they will get enough of their light requirements to produce flowers, grow sturdy stems, and produce the glucose that they need for their food.

As mentioned, the Floating arum loves the sun, but sometimes too much can hurt it. However, too much harsh sunlight can actually burn the leaves in the summer. When planted in the ground, you might want to add to their watering schedule so they will have protection. Exposure to the blades can result in sunburn, especially when the day's sun is too strong. It's highly recommended to spray some water to cool down the leaves a bit.

You need to minimize transplanting shock, especially for the young and newly-planted Floating arum. These species will need time to adjust to their new environment but make sure to choose a location where they will get the full sunlight they need. The amount of sunlight matters as well as the season. Water them during the hottest days to reduce stress, and you might want to cover the young ones when the temperatures are extremely high. Row covers and shade cloths might be applicable for the younger ones, but the mature plants might not need them, especially if they already have established roots and stems. When you see that the Floating arum begins to lose its color, this might be because it is not receiving enough sunlight to do photosynthesis. There's not enough chlorophyll to depict a green color; if this is the case, you need to transfer it to an area receiving bright sunlight.

The best temperature for Floating arum depends on the time of year. There are two primary seasons to discuss for temperature: the growing season, and the dormancy season. During the growing season, once Floating arum has begun to sprout, the ideal temperature range should be anywhere from 65~80℉(18~27℃). Any colder than 15℉(-10℃), and the plant will suffer; its leaves may brown and wilt, but if this is a short cold snap, then Floating arum may be able to survive with some help. During the warmer parts of the year, Floating arum will need to be similarly protected from temperatures that are too high. 95-105℉ (35-40℃) is the top of this plant’s temperature range, and anything above that will compromise the integrity of the foliage and blooms of Floating arum. Hotter temperatures can cause wilting, drooping, and even sunburn on the leaves, which can be difficult for Floating arum to recover from. There are quite a few ways to combat this issue that are quick and easy!

If this is the first year of your Floating arum outside as a new plant, then it may need a little extra tending during the coldest months of the year. Not only can frost more severely damage a first-year Floating arum, but it can also prevent it from growing back as a healthy plant come spring. This plant needs to be kept at 40℉(5℃) or above when they’re not yet established, which can be done either by bringing your Floating arum inside for a month or two, or putting up mulch or fabric barriers that protect from frost damage. It’s also a good idea to plant Floating arum in a shadier spot during the first year or two, as smaller and weaker plants have a more difficult time maintaining their own temperatures in the heat. First-year Floating arum should receive no more than five hours of direct sunlight per day, particularly if the ambient daytime temperature gets above 80℉(27℃). Shadecloth and frequent watering or misting are the keys to summer heat control.

If cold temperatures (below 15℉(-10℃)) do occur during the growing season, there are a few measures you can take to help protect Floating arum from frost or cold damage. If you’re growing Floating arum in a container, then the container can simply be brought inside in bright, indirect light until the temperatures rise up over the lower threshold again. Another option that’s better suited for ground-planted Floating arum is to use mulch or horticultural fabric to create an insulated barrier around the plant, which will protect the plant from frost and cold wind. For temperatures that are hotter than 80℉(27℃) in the shade during the day, be careful to only expose Floating arum to six hours or less of sunlight per day, preferably in the morning hours. Putting up shade cloth, or a fine plastic mesh, can help reduce the amount of direct sunlight that hits the plant during the hottest parts of the day. You can also install a misting system that allows for a slow release of cooling mist around the base of the plant during the day to lower ground temperatures.

During the cold winter months, Floating arum needs a certain measure of cold in order to stay in dormancy until it’s time to sprout. Sprouting too early, that is before the danger of the last frost has passed, can be fatal to Floating arum, especially if it’s already had a head start when the frost hits. Winter temperatures should ideally stay below 32℉(0℃), but if they get up to 40℉(5℃), everything will be just fine. An unexpected warm spell during the cold months, which can happen in more temperate climates like woodland rainforests, can trigger a premature sprout from Floating arum. In this case, if there’s still imminent danger of frost, you may want to try covering it with clear plastic on stakes so that the cold has less of a chance of damaging the new sprout. This setup can be removed when the danger of frost has passed. Occasionally, Floating arum will be able to resprout at the correct time without any help, but this method increases the chances of a successful second sprouting.
