If you decide to water your Dawn redwood, you will be happy to find that it is a straightforward task. One of the easiest ways to water this tree is by simply turning on your garden hose and using it to soak the soil slowly. Your garden hose is the ideal watering tool to use for mature Dawn redwood trees, as large specimens may need a high volume of water during each watering. However, for smaller trees, you may get by by using a watering can or some other smaller watering tool. Also, you should try to avoid overhead watering as excessive moisture on this plant’s leaves can lead to disease, especially when the tree is young.

At times, overwatering can be the result of poor soils. Mainly, if the soil in which your Dawn redwood grows does not allow water to drain effectively, the plant will likely begin to decline. If this is the case, you should either amend the soil to improve its drainage characteristics or transplant your Dawn redwood to a more favorable growing location. If you grow your Dawn redwood in a pot, this can also mean you may need to repot your plant with looser soils in a container that allows for better drainage. An overwatered plant may also contract diseases, which you should try to treat immediately. For an underwatered Dawn redwood, the remedy is quite simple. Begin watering more often, and soon your plant will bounce back and return to full health. The easiest way to tell if you have overwatered your Dawn redwood is to observe the plant’s foliage. Specifically, looking at the new growth will give the clearest sign of whether this plant suffers from too much moisture. An overwatered Dawn redwood may produce new growth, but that new growth may be discolored or prone to easy breakage. Another sign that the soil for your Dawn redwood is too moist is if you notice standing water or that water is not draining quickly in your plant’s growing area. Underwatered Dawn redwood trees will also have symptoms present in the foliage. In this case, the leaves may become sparse, brown. Usually, Dawn redwood can grow well with rainfulls. If you see such symptoms on your plant, you should consider if there has been too much rain recently or constantly high temperatures, which will help you to make the correct judgment.

A mature Dawn redwood does not need much water at all. In most instances, this tree will become drought tolerant and survive off of nothing more than rainfall. At most, you’ll need to water this plant about once per week during the hottest months of the year, but during other seasons, you probably won’t need to water it at all. The exception to that rule is if you are dealing with a plant that has been newly planted. If that is the case, you should water regularly to maintain consistent soil moisture and help the roots establish themselves. With that said, the most important thing to remember when watering Dawn redwood is that this species does not tolerate standing water. As such, when in doubt, you should err on the side of not watering your Dawn redwood rather than risking watering it too much.

The height of summer is one of the few times that you’ll need to water your Dawn redwood. At that time of year, it is typical to give this plant about one inch of water per week. However, that amount can change depending on how much it has rained. If it has rained one inch or more that week, you won’t need to give any water to your Dawn redwood.newly planted Dawn redwood will need more water during the establishment period. Typically, this amounts to watering about once every one to two weeks for the first few growing seasons.

The Dawn redwood tree will need the most water during the summer months when the weather is the hottest. At that time, you should give this plant water about once per week in the absence of rainfall. During other times of the year, this plant will often survive with no water at all. In spring and fall, you might need to provide some water if the weather is exceptionally hot, but this is rare. Unlike many other plants, the Dawn redwood does not enter full dormancy in winter, which means that it will continue growing, during the coldest months. Still, the water needs during winter will remain quite low as the cool temperatures will not cause the soil to dry out quickly..

Young Dawn redwood trees need significantly more water than those that are established. A newly planted tree should receive water at least weekly to ensure that the soil remains moist to facilitate root development. After the first growing season, your Dawn redwood should be well-adapted to its new growing location and should need much less water. At this time, you can begin following the standard instructions for watering this species, providing supplemental water about once per week during summer when it does not rain. Beyond that, there is no other time at which you’ll need to alter your watering habits based on the growth stages of the Dawn redwood tree.

It is far more common to grow the Dawn redwood in an outdoor growing location. However, it is also possible to grow this plant indoors in a container. In that scenario, one gardener often raise the Dawn redwood as the bonsai plant. Whether you grow this plant indoors or outdoors, you can expect its water needs to remain relatively similar. The one difference is that you may need to water an indoor Dawn redwood tree a bit more. Indoor plants won’t have access to rainfall during the summer. Also, indoor areas are often much drier than outdoor growing locations, and the size of the pots limits the water-retainability, which can lead to higher water needs.

Despite having a relatively fast habit of growth, Dawn redwood does not require very much pruning. It is not necessary to routinely prune this tree, however, it does require some pruning every once in a while. Pruning can be done to tidy this tree up and remove any diseased or damaged foliage. Or Dawn redwood can be pruned for shaping.

Dawn redwood should be pruned as needed. Typically, these trees should be pruned to remove any damaged, yellowing, dying, or dead foliage. It is also necessary to prune this plant to remove any shoots that are congested or are crossing. The best time to prune Dawn redwood is between late winter to early spring. This is the period when pruning causes the least damage to the plant.

Pruning Dawn redwood is a fairly easy task if you know what to look for. To prune these trees, you will need a pair of sharp pruning shears. Using your pruning shears, remove any damaged or diseased parts of the tree. Keep an eye out for any shoots that are becoming congested or are beginning to cross and remove them. Ideally, you should steer clear from pruning any of the tree’s lower limbs. Leaving these intact will allow the tree to have a more natural and open form. Additionally, leaving the lower limbs alone will help to prevent any disease-inducing stress, as well as suckers from forming.

There are no special requirements to follow after you have pruned your Dawn redwood. It is recommended, however, that you dispose of any diseased foliage that has been removed from the tree away from any other plants. This is to avoid spreading the disease to other plants. After pruning your Dawn redwood, you may apply a fertilizer treatment to encourage faster growth. Do not water the plants immediately after pruning as this can lead to fungal infestation of the plants through the wounds.

The best time to prune Dawn redwood is between late winter to early spring. This is the period when pruning causes the least damage to the plant. Keep an eye out for any shoots that are becoming congested or are beginning to cross and remove them. Ideally, you should steer clear from pruning any of the tree’s lower limbs. Leaving these intact will allow the tree to have a more natural and open form. This will increase ventilation and light, reduce disease infection and allow Dawn redwood to grow more vigorously. When pruning branches you need to leave the strong ones and remove the weak ones, keeping healthy auxiliary branches that grow outwards at about 45 degrees. Branches that are too angled or too small should be removed. Pruning Saw is required if the branch is more than three quarters of an inch in size, pruning should be done in the direction of the "Branch bark ridge" to the "Branch collar" to allow for good healing. Branches that require a saw need to be pruned using the "three-cut method", which prevents the bark of the branch from tearing and creating cracks in the trunk, which can be detrimental to the recovery of the plant. Finally, you may prefer to just trim off dead or damaged portions of the plant to keep it looking its best as if it's possible. This can be done at any time of year. Diseased or damaged stems should be cut right at the soil line and removed completely.

The best thing to remember about Dawn redwood is that they do not require routine pruning. Your tree will likely grow better if you prune it as and when it is necessary and no more than that. Additionally, you should also keep in mind that it is better to leave the lower limbs of this tree alone to prevent stress-induced diseases from attacking your tree. Different diameter branches require different pruning tools. If the tree is too tall, pruning needs to be done safely or by a professional.

For healthy growth, make sure that Dawn redwood receives at least 3–6 hours of sun each day. This is actually a minimum requirement—most plants that can handle part sun can also thrive in full sun, but because they require less light for photosynthesis, they are more flexible than plants that require full sun or part shade.

Dawn redwood does best with exposure to full or part sun. They will perform best with direct morning light, but in summer they need protection from the strong afternoon sun. In temperate environments, too much hot afternoon sun can burn the leaves, damaging the plant's appearance and health.

Dawn redwood planted indoors can easily be damaged by direct sunlight when it's moved outdoors. The best way to prevent sunburns from overexposure is to move pots gradually from a shaded area to a brighter spot, gradually. But even plants that are acclimated to the summer sun can be damaged by extreme heat. In a heatwave, it is important to keep the soil consistently moist so that plants can cope with excessive levels of heat. Moving plants in containers to areas with afternoon shade or erecting a shade cloth over them can protect sensitive Dawn redwood during extreme weather events.

While bright morning sun and some full sun exposure can be highly beneficial for Dawn redwood, the harsh, hot midday sun of summer can be too much to handle. If planted in the ground, the summer sun will usually ramp up slowly enough through the season for Dawn redwood to gradually adapt to its intensity. But a potted plant that has been indoors or in a protected location will often suffer injury when placed suddenly into a location where the direct summer sun reaches it in the hottest part of the day. To protect this plant from the brutal afternoon summer sun, plant or place it in an understory location where it is shaded at midday by taller trees and plants or by a building or landscape feature.

When Dawn redwood receives too little sun, they may become pale green or display drooping, yellow leaves. While some leaf drop is normal, if leaves are dropping but no new ones are growing in to replace them, it is a sign that something is wrong. If Dawn redwood receiving inadequate light does manage to grow, the new growth is often spindly, pale, and prone to insect infestation. Paying attention to these signs and changing the lighting conditions of the plant will make a significant difference.

Tender, new leaves are especially sensitive to sunburn. Bearing this in mind, very young Dawn redwood and when it's in a strong growth phase, such as in late spring and early summer, will be more sensitive to harsh sun and heat than the mature one or those in a more dormant fall growth stage. Dawn redwood fresh from a nursery is also usually not prepared for strong full sunlight and must be introduced to it slowly.

Recently transplanted Dawn redwood will often experience a bit of shock and will need to be cared for carefully, either shaded from bright afternoon sun or placed in a protected area. On very hot days, you may see the leaves of Dawn redwood drooping—this is usually nothing to worry about. Plants will send the water in their leaves down into their roots to protect them from burning. However, if the leaves are still drooping in the evening or the next morning, the plant needs water. Always avoid watering during the hottest times of day, as sunlight can hit wet leaves and scorch them easily. Dawn redwood that has been underwatered will be weaker than that with consistently moist soil. This can leave it with weak roots that are unable to protect the leaves on hot, sunny summer days by diverting water away from the leaves. Care for an underwatered plant by giving it a long, deep watering and then allowing the top two inches of soil to dry out before the next watering. Even if it loses its leaves, if cared for properly it will grow new ones.

The best temperature for Dawn redwood to thrive is 65~80℉(18~27℃). During the primary growing phase, the highest temperature tolerable would be 95℉(35℃), while the lowest tolerable temperature would be 15℉(-10℃). This species is tolerant of low temperatures and will survive freezing winters. The perfect, highest, and lowest temperature range: Perfect：65~80℉(18~27℃) Highest：85~95℉(30~35℃) Lowest：-5~15℉(-20~-10℃) or below

Research shows that Dawn redwood will begin to exhibit signs of stunted growth during prolonged periods of higher temperatures, especially during the development of axillary buds and the growth of main shoots. Keeping the temperatures consistent and cooler, around 65℉(18℃), will encourage vigorous growth after germination or transplanting.

Dawn redwood can withstand freezing temperatures when planted in the ground in areas that don’t get below of 15℉(-10℃) as an extreme temperature during the winter months. But if planted in pots or containers, then their roots must be protected from the winter cold. Do this by wrapping the container in a blanket or bringing it inside where it will be fully protected from the elements.

Greater harm will come to Dawn redwood if the temperature is consistently too high versus too low. If Dawn redwood gets too hot, seed germination and photosynthesis efficiency is lessened due to hormone triggers caused by heat stress. The plant will show signs through wilting, leaf browning, and potentially death. If Dawn redwood gets too cold, plant functions such as nutrient uptake and photosynthesis will cease, resulting in the possible death of the plant. If a single freezing event occurs during the growing season, then a membrane phase transition might occur, which can cause a cease in plant functions and death of the plant.

Keeping the soil temperature consistent is one of the most important strategies to keeping Dawn redwood healthy, which leads to successful budding, flowering, and new growth. Do this by consistently watering, adding mulch to bare soil, and planting in the shade.

Due to the cold tolerance of Dawn redwood, heating pads will not be necessary if planted outside in the ground. If the plant is in an outdoor pot, then bring it inside a heated house and place it in a sunny window during the winter months.

To ensure adequate temperature conditions are present, plant Dawn redwood in an area with partial shade. If possible, use afternoon shade to provide the best protection during the hottest part of the day. This will also result in lower temperatures in the soil due to increased moisture retention. If Dawn redwood is planted indoors, then keep the container away from windows and out of direct sunlight during the summer months to prevent the soil temperature from spiking daily.

During the summer or times of high heat, give Dawn redwood extra shade and water to help cool its leaves, roots, and soil. During cold snaps or growing season freezes, cover sensitive budding vegetation with frost cloth or water using sprinkler systems. If it’s only nearing freezing temperatures for a short period, then water during the day several hours before the freeze. If the temperature is predicted to remain below freezing for an extended period, then keep the sprinkler running until the temperature rises above freezing the following day.

Dawn redwood is a mid-temperature plant that can easily tolerate the typical fluctuations of the seasons and remain a hardy species when planted in maintained landscapes areas, containers, or indoors. Therefore, adjusting the temperature during the different seasons is unnecessary for primary growth. If flowering is stunted or impeded, then allowing the plant to experience a season of winter freeze could help to revive flowering.

If it becomes too difficult to lower the temperature for an indoor plant during the summer, then plant it outside in the ground or in a container. Make sure to plant Dawn redwood in a shaded location and water often to keep the soil moist.

Fertilizing Dawn redwood in the spring encourages healthy growth. Remember, the plant has a long lifespan, and it needs to be supported. Adding nutrients to the soil can also improve the plant’s health, making it better able to resist common pests and diseases that can stunt growth or shorten its lifespan.

The growing medium doesn’t always supply enough nutrients to support healthy growth. However, Dawn redwood is a little different from your garden annuals and perennials. It doesn’t require a lot of extra nutrients. The best time to fertilize Dawn redwood is in the spring before new growth appears.

Some plants thrive with monthly or weekly fertilization, but not Dawn redwood. It does not require a lot of extra nutrients. Too much fertilizer can cause it to start dying back. Only apply fertilizer in the spring, skipping the other seasons. In the summer, fall, and winter, do not add fertilizer or organic matter to the soil.

The age of your plant plays a role in the type of fertilizer but remember Dawn redwood does not require a lot of extra nutrients. Look for a balanced plant food, it will help support healthy root development and growth but stay away from fertilizers with high nitrogen contents.

How you fertilize Dawn redwood is as important as when you add the extra nutrients. Apply the fertilizer once in the spring, around the base of the plant. Try to avoid getting any fertilizer on the trunk. If you are using a granulated fertilizer, cover the pellets with a light layer of soil. It helps ensure the fertilizer is absorbed into the soil.

It can be tempting to keep feeding Dawn redwood throughout the spring and summer. You want to encourage healthy growth, but too much fertilizer can have disastrous consequences. All types of fertilizers contain nitrogen, and the nutrient does support healthy growth. However, too much nitrogen can result in root burn.
