FREQUENTLY ASKED

Reader questions.

How should I water my Paperplant?

Your Paperplant is not particular about how you water it, so you can use various watering tools like watering cans, hoses, or cups. It is essential to water the plant by directly applying water to the soil, ensuring that all areas are equally moistened for the root system's benefit. Using filtered water is recommended to avoid harmful particles present in tap water. Additionally, using water that is at or slightly above room temperature is beneficial as extreme temperatures can be shocking to the Paperplant. However, the Paperplant generally thrives with any type of water you provide.

Why do I have to put fertilizer on my Paperplant?

If you own a Paperplant, regular fertilization is important regardless of the type of plant you have. Providing the proper nutrients will help your plant grow stronger and be better equipped to handle difficult growing conditions, as well as fend off diseases and pests. The foliage of your Paperplant is particularly attractive, so it's crucial to maintain its health. This involves following a regular fertilization schedule that is tailored to your specific Paperplant, resulting in vibrant leaves and an overall lush appearance.

What are the sunlight requirements for Paperplant (Fatsia japonica)?

Paperplants thrive in environments that provide less intense light, requiring less than 3 hours of sunlight for full shade conditions, and about 3-6 hours of sunlight for partial sun conditions. It's important to observe how sunlight moves through your garden to ensure your plants receive the ideal balance of light and shade, which is crucial for their growth and health.

What is the native habitat of the Paperplant (Fatsia japonica)?

The Paperplant, also known by its botanical name Fatsia japonica, is native to Japan and Korea. This plant thrives in a temperature range between 59 to 95°F (15 to 35°C). It enjoys the warmth of the summer but may need some afternoon shade to protect it from overheating. In the winter, it is capable of tolerating cooler temperatures down to 23°F (-5°C), provided it is planted in well-draining soil. Paperplant exhibits a moderate level of cold tolerance and typically doesn't need special care above -5°C. However, in anticipation of temperatures dropping below this point, taking temporary measures such as wrapping the plant with plastic film, fabric, or other protective materials can help. It's crucial to remove this protection once temperatures rise to ensure the plant remains healthy.

What should I do if I give my Paperplant too much water or too little water?

When it comes to outdoor plants, particularly newly planted ones or seedlings, the biggest issue they face is insufficient watering. It's important to remember to consistently water them adequately for the first few months, especially when they are small or recently planted. This is because once the roots have established themselves, outdoor plants usually rely on rainwater for most of their needs. In the case of potted Paperplants, the opposite problem often arises - overwatering. If you accidentally overwater your Paperplant, you should take immediate action to address the issue. Firstly, stop watering your plant right away to minimize the effects of overwatering. Then, remove the Paperplant from its pot to check its roots. If the roots show no signs of rot, you can return the plant to its container. However, if there are signs of root rot, trim away the affected roots and apply a fungicide to prevent further damage. Lastly, ensure that you repot the Paperplant in well-draining soil. On the other hand, underwatering a Paperplant is usually easier to fix. If you notice the plant's leaves drooping, drying out, or falling off, it's a sign of underwatering. Water the plant more frequently, and you'll quickly see the leaves regain their fullness. It's important to correct your watering frequency promptly when you notice underwatering happening.

When should I put fertilizer on my Paperplant?

To help your Paperplant grow strong and healthy, it's best to fertilize it for the first time in late winter or early spring. This will provide the necessary nutrients for the plant to thrive once the weather warms up. If you live in a warm climate, it can also be beneficial to give your Paperplant an additional fertilizer feeding in early fall. This not only adds more nutrients to the soil for the upcoming growing season, but also helps the plant withstand the winter cold without foliage damage. By fertilizing earlier, you ensure that the new branches have enough time to grow and be resilient against the cold winter.

How should I manage artificial lighting for Paperplants?

For indoor Paperplants, adequate lighting is vital, especially when natural sunlight is insufficient. Artificial lights, like LED lights that can be customized to provide specific wavelengths, are beneficial. For full sun plants, 30-50W per square foot is recommended; partial sun plants require 20-30W per square foot, and full shade plants need 10-20W per square foot. The light source should be placed 12-36 inches above the plant, mimicking natural sunlight as closely as possible. Most plants will need 8-12 hours of light per day to promote healthy growth.

How does Paperplant react to low temperatures, and what are the solutions if it gets too cold?

Paperplant has a moderate tolerance to low temperatures and performs best when the mercury stays above 15°C. When winter arrives, it's crucial to ensure the temperature does not fall below -5°C to avoid stressing the plant. If temperatures descent beyond -10°C, the leaves of Paperplant may begin to droop; if the cold is mild, they might recover, but more severe cold will cause the leaves to wilt and eventually drop. The solution for helping a Paperplant survive colder times involves trimming off any parts damaged by frost. Before cold temperatures hit again, it's advisable to wrap the plant in non-woven fabric or cloth and construct a wind barrier to shield it from chilling winds.

How frequently should I water my Paperplant?

When it comes to outdoor plants, most of them can rely on rainfall to grow normally. However, if there is a lack of rainfall in your area, you should provide adequate watering for your plants every two weeks in the spring and fall. In the summer, you'll need to water more frequently. During the slower growth period in winter, you can water less often or even not at all. If your Paperplant is young or has just been planted, it will require more frequent watering to help it establish and grow into a more adaptable and drought-tolerant plant. If you have potted plants, there are two main approaches to determine how often to water your Paperplant. The first is to follow a predetermined watering schedule, which suggests watering once a week or every other week. However, this method may not take into account the specific conditions of your growing environment. The watering frequency should be adjusted based on the season as well. During summer when the plant's water needs are highest, relying solely on a predetermined schedule may not be enough. An alternative approach is to monitor the soil moisture and wait until the top two to four inches of soil (about ⅓ to ½ depth of the pots) have completely dried out before watering again.

When is not a good time to add fertilizer to my Paperplant?

There are specific times throughout the year when you should avoid fertilizing your Paperplant. Firstly, during the early and mid-winter months, the Paperplant is dormant and does not require any nutrients. Additionally, it is not advisable to fertilize this plant during the late spring and throughout the summer. During this period, the weather tends to be hotter and drier, which can have a detrimental effect on the Paperplant if it is given fertilizers. To prevent any negative consequences, it is recommended to stick to a fertilization schedule that involves feeding only in the early spring and early fall.

What are the common symptoms of light deficiency in Paperplants?

When Paperplants don't receive enough light, they may exhibit several symptoms including lighter-colored new leaves, indicating a lack of chlorophyll and essential nutrients. Growth may slow down or halt entirely, and the plant might shed older leaves earlier than usual to conserve resources. Other symptoms include chlorosis, sunscald, leaf curling, wilting, and leaf scorching. These signs indicate the plant's struggle with light conditions, either due to deficiency or overexposure.

What should be done if a Paperplant experiences high temperatures?

During the hot months of summer, the Paperplant should ideally be kept in conditions below 35°C. Exposure to temperatures above 41°C can cause the leaves to lighten in color, tips to dry and wither, leaves to curl, and increases the risk of sunburn. If this occurs, the solution involves trimming away the parts of the plant that have been sunburned or dried up. To protect the plant from further damage, it should be moved to a place with afternoon and midday shade or covered with a shade cloth. Additionally, watering the plant in the early morning and late evening will help keep the soil moist and support the plant's well-being through high temperatures.
