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

Cobra lily requires about 3-6 hours of direct sunlight each day to thrive. However, it also needs some shade during the hottest parts of the day to prevent sun damage. Morning sunlight is ideal for Cobra lily, but it can also tolerate some afternoon sun if the temperature is not too hot. To provide the perfect balance of sunlight, try planting Cobra lily in an area that gets partial sun, such as under a tree or on the east side of a building.

If Cobra lily is exposed to too much direct sunlight, its leaves may turn yellow, dry out, or even burn. You may also notice that the plant wilts or becomes stunted. To prevent sun damage, make sure to give Cobra lily some shade during the hottest parts of the day. You can use a shade cloth or plant Cobra lily near taller plants that can provide some natural shade.

If Cobra lily doesn't get enough sunlight, it may grow tall and lanky, with sparse foliage. The leaves may also turn yellow or pale green, indicating that the plant is not producing enough chlorophyll due to lack of sunlight. To remedy this, try moving Cobra lily to a sunnier spot, or prune nearby foliage to allow more light to reach the plant.

The best temperature for Cobra lily 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 Cobra lily 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 Cobra lily may be able to survive with some help. During the warmer parts of the year, Cobra lily 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 Cobra lily. Hotter temperatures can cause wilting, drooping, and even sunburn on the leaves, which can be difficult for Cobra lily 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 Cobra lily 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 Cobra lily, 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 Cobra lily 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 Cobra lily 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 Cobra lily 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 Cobra lily from frost or cold damage. If you’re growing Cobra lily 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 Cobra lily 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 Cobra lily 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, Cobra lily 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 Cobra lily, 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 Cobra lily. 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, Cobra lily will be able to resprout at the correct time without any help, but this method increases the chances of a successful second sprouting.
