The manner in which you water the Pacific coralroot will depend somewhat on whether or not your plant is in an active growth phase. If so, you should apply water to your plant’s soil and, if the weather is warm, perform occasional overhead watering to allow the plant to absorb moisture through its leaves. By contrast, in winter, and when the weather is cool or wet generally, you should stick to watering the soil directly rather than including overhead watering as well. You’ll know your Pacific coralroot needs more water if its roots and leaves become thin and dry or show discoloration. Pacific coralroot receives too much water will look mushy and limp. You should grow your Pacific coralroot in a pot and ensure that the potting mix you use has fantastic drainage. During the growing season, you’ll need to water this plant multiple times per week. However, each watering should drain quickly through the growing medium to prevent any standing water. The amount of water you give will change based on the size of the pot you use. Generally, pots that are a bit larger will need water less frequently, while smaller pots will have a slightly more frequent watering schedule. Rainwater and distilled water are the best kinds of water to use for this plant, and it is best if the water you use matches the temperature of the air as closely as possible.

Allowing your Pacific coralroot to sit in soil that remains too moist for too long is one of the most common ways to kill this plant. While these plants need water frequently during active growth, they also need to live in a growing medium that drains water rapidly. When this plant experiences overwatering, it will become mushy and develop root rot. If that occurs, you should be prepared to use a pair of sterile pruning shears to cut out any roots that show signs of rot. After doing that, you should then repot your Pacific coralroot, ensuring that the container allows for drainage and that you fill the container with a fast-draining potting mix. However, Pacific coralroot doesn’t typically respond that well to excessive repotting, so it is crucial to get your watering rate right. Underwatered Pacific coralroot will begin to shrivel and feel dry to the touch. If this occurs, it is likely because the soil is drying out faster than you expected, which means you should increase your watering frequency.

During the active growth stage, which spans the spring and summer months, you should plan to water your Pacific coralroot about once or twice per week while increasing that rate to three times per week or more in the case of long periods of hot and dry weather. In the winter, you will also need to water your Pacific coralroot, but not nearly as much. A watering frequency of two to three times per month should be enough to keep your Pacific coralroot alive during the coldest months. However, if you keep your Pacific coralroot indoors during winter, you should account for the fact that indoor growing locations can cause the soil to dry quicker than usual, which may mean you need to increase the number of monthly waterings. You can use the fall as a time to gradually reduce your watering frequency from the summer rate of multiple times per week down to your reduced winter watering schedule.

There are two important growth phases that you should consider when planning the watering schedule for your Pacific coralroot. The first of those periods is the active growth period, which happens in spring and summer, and which calls for watering this plant multiple times per week. The second important growth period is the rest period that the Pacific coralroot should experience for about two to three months each year during winter. During that time, your plant will need far less water and fertilization than normal. Water about once or twice per month during this time. During the fall, you should begin to gradually reduce your watering frequency from multiple times per week all the way down to the once or twice per month rate that is appropriate for winter.

The Pacific coralroot requires a growing environment that is relatively humid. Unfortunately, most indoor growing locations will lack the level of air moisture that this plant prefers. This causes the plant and its soil to dry out more quickly than it would when growing outdoors. To combat this effect, you may want to include a humidifier in the room where you grow your Pacific coralroot. You may also need to water it a bit more frequently as well. However, while Pacific coralroots do prefer humidity, they also require adequate air circulation as well, to prevent excessive moisture build-ups and the diseases that can result. Consider including a fan in the room where you grow this plant as well to ensure proper air circulation remains present.

Pacific coralroot 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 Pacific coralroot, but it can also tolerate some afternoon sun if the temperature is not too hot. To provide the perfect balance of sunlight, try planting Pacific coralroot in an area that gets partial sun, such as under a tree or on the east side of a building.

If Pacific coralroot 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 Pacific coralroot some shade during the hottest parts of the day. You can use a shade cloth or plant Pacific coralroot near taller plants that can provide some natural shade.

If Pacific coralroot 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 Pacific coralroot to a sunnier spot, or prune nearby foliage to allow more light to reach the plant.

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