How much sunlight should Common reed get per day to grow healthily?
Common reed 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.
What type of sunlight does Common reed need?
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 Common reed 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.
Should I protect Common reed from sun exposure?
The Common reed 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.
What will happen if Common reed gets inadequate sunlight?
If there's insufficient light, the Common reed 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 Common reed 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.
Does Common reed need special care about sunlight during its different growth stages?
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 Common reed 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.
How much light does Common reed need for photosynthesis?
As mentioned, the Common reed 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.
How to protect Common reed from sun and heat damage?
As mentioned, the Common reed 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.
Are there any cautions or tips for sunlight and Common reed?
You need to minimize transplanting shock, especially for the young and newly-planted Common reed. 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 Common reed 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.
What is the optimal temperature for Common reed?
The best temperature for Common reed 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 Common reed 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 Common reed may be able to survive with some help. During the warmer parts of the year, Common reed 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 Common reed. Hotter temperatures can cause wilting, drooping, and even sunburn on the leaves, which can be difficult for Common reed to recover from. There are quite a few ways to combat this issue that are quick and easy!
Temperature requirements for first year or seedling Common reed
If this is the first year of your Common reed 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 Common reed, 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 Common reed 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 Common reed 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 Common reed 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.
How can I protect Common reed from extreme temperatures?
If cold temperatures (below 15℉(-10℃)) do occur during the growing season, there are a few measures you can take to help protect Common reed from frost or cold damage. If you’re growing Common reed 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 Common reed 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 Common reed 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.
Dormant season temperature recommendations for Common reed
During the cold winter months, Common reed 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 Common reed, 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 Common reed. 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, Common reed will be able to resprout at the correct time without any help, but this method increases the chances of a successful second sprouting.
