Oleandra wallichii
Catenulated shield-fern is an herbaceous creeping fern found in temperate to subtropical mountain forests. Unlike most ferns, its leaves are simple and may dangle from the branch or rock it clings to instead of growing upright. It is part of a group of ferns called "crevice creepers" for their tendency to grow in rock crevices. Like several rhizome-based ferns, it alternates its reproduction strategy every year, sprouting a new plant from its rhizome one year and spreading spores the next.

Temperature Temperature Temperature
What is the optimal temperature for Catenulated shield-fern?
Colder temperatures can affect plants since they have the same temperature as the air around them. When they are exposed to the sun, they can start to get warm again, but this is not the case during winter. The temperature range for the Catenulated shield-fern is often 70~85℉(21~30℃). They might tolerate 20~30℉(-6~0℃) even 15℉(-10℃), but not for long since this can result in frost damage. Maximum temperatures should be around 70~85℉(21~30℃), but make sure that you spray them with water from time to time and give them some shade to prevent wilting.

Should I adjust the temperature for Catenulated shield-fern during different growing phases?
Do some research and make sure that the temperature is right when growing Catenulated shield-fern. Some growers might consider decreasing the plants' thermostats during the growing season to reduce HVAC costs. However, it's vital to understand that the temperature can affect the flowering, pest management, and quality of the plants.
There will be a temperature point where the Catenulated shield-fern will stop growing, and this can happen during the winter when some species might go into a dormant state. The base temperature becomes warmer when the season changes and the Catenulated shield-fern can grow faster. The species that are naturally growing in warm habitats have higher optimum temperatures when you compare them to the ones that thrive in a cooler climate.
When the seeds of Catenulated shield-fern are exposed to cool temperatures, this can cause a decrease in uniformity and delays. You might also want to lower the temperature during flowering but not at other phases. Cooler temperatures at night will also require less water, so adjust the irrigation as needed.

How can I keep Catenulated shield-fern warm in cold seasons?
Stop fertilizing the plant to avoid new growth and allow the old ones to become hardy. This way, they can endure colder temperature when it begins to drop. To keep them warm, you can build structures around the Catenulated shield-fern like cages or trellises. There are also options to use heat mats that can gently warm the soil since they can consistently maintain an ideal temperature range for the Catenulated shield-fern.
Read More more
How can I save Catenulated shield-fern from temperature damage?
During winter, you can protect the Catenulated shield-fern from frost by covering it with cloths, tarps, burlaps, sheets, or plastic buckets. Make sure to keep them down so they continue to act as insulators and the wind will not blow them away. However, ensure that the plastic sheets or burlap covers should not touch any part of the fruit or foliage, or the cold temperatures can transfer to the material and cause burns. When the temperatures begin to rise during the daytime, remove the covers.

Should I adjust the temperature for Catenulated shield-fern in different seasons?
When growing the Catenulated shield-fern in spring, you might want to increase humidity since the air temperature tends to be cooler at this time. A dry temperature can be a stressful growing environment for various species, which can help. If summer arrives, the large cover of the greenhouse and the warm temperature will mean that there will be a higher humidity level in the air. Some signs to look for are the condensation that is often found on the walls of the greenhouse, and this can cause issues with pollination and the development of infections when the water begins to fall on the leaves. Make adjustments according to the temperature and do some spraying during the hotter days of the year.

What damage will Catenulated shield-fern suffer if the temperature is too high/low?
Generally, the first cold snap can destroy the Catenulated shield-fern and others might go into a dormant state when the temperature is low. Some plants can get chilled when the temperatures range from 20~30℉(-6~0℃). They can freeze when the temperature begins to drop below 32℉(0℃). Those species that hide most of their parts under the soil might lose their structures above ground, but they can recover in spring. Some of the associated issues with too low temperatures are the lack of availability of resources like water, and nutrients, and those subtropical plants can suffer when the temperature reaches below 20℉(-6℃). The plants can also get damaged because of extreme heat stress when it's too high. This can reduce the transpiration rate that can affect the growth and productivity of Catenulated shield-fern.

What tips and cautions should I keep in mind when it comes to temperature for Catenulated shield-fern?
You need to cover the plants at night since these can add about 5 degrees more to protect the species from frost and freezing temperatures. The cloth rows can work well as blankets and ensure that there are no openings where the heat could escape.
When using the covers, avoid the plastic from touching the foliage because this can cause the Catenulated shield-fern to freeze. Remember to keep the covers during the day and stop using heat pads during the summer. It will always be worth the effort to protect the cold-intolerant plants from freezing temperatures to help them survive.

How can I keep Catenulated shield-fern warm without a heat pad?
If you prefer not to use a heat pad, bring the Catenulated shield-fern inside, especially if it's freezing outdoors. During spring, consider the ones you need to bring indoors and plant them in moveable pots and containers.
Read More more
How can I provide Catenulated shield-fern with an adequate temperature condition?
Most often, the ones caring for the Catenulated shield-fern will grow them in greenhouses. This is because they can provide adequate temperature in these areas that won't affect the photosynthesis process of a specific process.
Some install the proper HVAC systems to control the temperatures of Catenulated shield-fern. This can handle many species' cooling and heating needs, especially during the summer and winter. They generally place the cooling or heating pad under the plants rather than above to achieve their desired temperatures.
If outdoors, you can protect the Catenulated shield-fern from frost by covering it with cloths, tarps, burlaps, sheets, or plastic buckets.
Read More more
Under what conditions should I stop adjusting the temperature for Catenulated shield-fern?
Heat mats are often left on Catenulated shield-fern to set the temperatures at a more consistent level. When the weather becomes warmer during the day, you can remove them, especially if the species are exposed to the sun. Put the pads away once the plants are established and when they start growing flowers and fruits.

Regional wintering strategies
Catenulated shield-fern has some cold tolerance and generally does not require any additional measures when the temperature is above {Tolerable_growing_temperature_min}. However, if the temperature is expected to drop below {Tolerable_growing_temperature_min}, it is necessary to take some temporary measures for cold protection, such as wrapping the plant with plastic film, fabric, or other materials. Once the temperature rises again, the protective measures should be removed promptly.
Important Symptoms
Symptoms of Low Temperature in Catenulated shield-fern
Catenulated shield-fern has moderate tolerance to low temperatures and thrives best when the temperature is above {Suitable_growth_temperature_min}. During winter, it should be kept above {Tolerable_growing_temperature_min}. When the temperature falls below {Limit_growth_temperature}, the leaves may start to droop. In mild cases, they can recover, but in severe cases, the leaves will wilt and eventually fall off.
Solutions
Trim off the frost-damaged parts. Prior to encountering low temperatures again, wrap the plant with materials such as non-woven fabric or cloth, and construct a wind barrier to protect it from the cold wind.
Symptoms of High Temperature in Catenulated shield-fern
During summer, Catenulated shield-fern should be kept below {Suitable_growth_temperature_max}. When the temperature exceeds {Tolerable_growing_temperature_max}, the color of the leaves becomes lighter, the leaf tips may become dry and withered, the leaves may curl, and the plant becomes more susceptible to sunburn.
Solutions
Trim away the sunburned and dried-up parts. Move the plant to a location that provides shade from the midday and afternoon sun, or use a shade cloth to create shade. Water the plant in the morning and evening to keep the soil moist.
