If you decide to water your Great basin bristlecone pine, 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 Great basin bristlecone pine 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 Great basin bristlecone pine 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 Great basin bristlecone pine to a more favorable growing location. If you grow your Great basin bristlecone pine 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 Great basin bristlecone pine, 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 Great basin bristlecone pine 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 Great basin bristlecone pine may produce new growth, but that new growth may be discolored or prone to easy breakage. Another sign that the soil for your Great basin bristlecone pine is too moist is if you notice standing water or that water is not draining quickly in your plant’s growing area. Underwatered Great basin bristlecone pine trees will also have symptoms present in the foliage. In this case, the leaves may become sparse, brown. Usually, Great basin bristlecone pine 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 Great basin bristlecone pine 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 Great basin bristlecone pine is that this species does not tolerate standing water. As such, when in doubt, you should err on the side of not watering your Great basin bristlecone pine rather than risking watering it too much.

The height of summer is one of the few times that you’ll need to water your Great basin bristlecone pine. 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 Great basin bristlecone pine.newly planted Great basin bristlecone pine 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 Great basin bristlecone pine 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 Great basin bristlecone pine 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 Great basin bristlecone pine 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 Great basin bristlecone pine 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 Great basin bristlecone pine tree.

It is far more common to grow the Great basin bristlecone pine 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 Great basin bristlecone pine 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 Great basin bristlecone pine 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.

Great basin bristlecone pine, like most other evergreen trees, absolutely need to be pruned in order for them to grow as happy, healthy trees. Of course, there are lots of reasons that pruning is important, so we’ll talk about those in greater detail. Pruning opens up the inner canopy to airflow and sunlight. Without keeping these pathways open, the inner canopy will be starved of sunlight and air. Therefore, pruning your Great basin bristlecone pine is not only advantageous, but it also weakens the impact of pests and infections by separating branches from one another. These benefits are far too easy to reap with Great basin bristlecone pine to neglect them. Aside from keeping your Great basin bristlecone pine happier and healthier, pruning just makes things look nice and tidy. Who doesn’t love a well-kept tree, anyway?

Great basin bristlecone pine can be pruned at different times depending on whether they’re grown indoors or outdoors. For outdoor trees, pruning and trimming should be done when the tree is not actively growing; this generally falls under the colder months of winter, but can vary depending on where you live. However, if you’re growing your Great basin bristlecone pine indoors, there are lots of different times of the year when it’s okay to trim lightly. For example, if you’re planning on trimming a bit off the top of just one or two smaller branches, then you can trim nearly anytime. For heavier pruning on indoor Great basin bristlecone pine, it’s best to wait until those same colder months when outdoor Great basin bristlecone pine wouldn’t normally be actively growing. Great basin bristlecone pine 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.

In order to keep your Great basin bristlecone pine growing strong, remove any branches or debris that landed at the base of the tree. Keeping the area clear can prevent weeds and underbrush from crowding out the tree, especially if it’s young. Another great tip is to use raw, organic honey to treat large open wounds on the Great basin bristlecone pine where branches were trimmed. The use of honey prevents any pathogens or potential pests from making their way in. It’s also a good idea to water a little extra after pruning for a week or two. Providing them with a little extra water helps them build natural calluses over the exposed core faster, so they can get back to growing into large, Great basin bristlecone pine!

While most of the Great basin bristlecone pine won’t need to be pruned until they develop some substantial height, sometimes their branches get a little carried away in the wrong direction. This is why this part of the Great basin bristlecone pine needs to be pruned in good time. Tools In order to prune your Great basin bristlecone pine properly, you’ll need the proper pruning tools. While smaller plant shears and garden scissors may not cut it (pun intended), handheld clippers, pruners and loppers will certainly help out. For very tall branches that are out of safe reach, use a pole saw with the necessary safety equipment. It’s also a good idea to wear gloves while pruning to avoid any splinters or cuts in general. How to Prune To prune your Great basin bristlecone pine, first cut away any dead, dying or diseased branches. Look for pests, irregular growth patterns, and brittle branches or leaves. Snip these off at the branch collar, where the branch intersection is, without scoring the main branch. Next, be on the lookout for extra long branches or leaves that may not be able to support a lot of weight. These branches or leaves will be too heavy and grow downwards, so this can be trimmed back if necessary. Try to find all of the branches that grow either directly up (that are not the primary trunk) and those that grow directly downward. These branches will become an issue because they can effectively block out light and air from inner branches. Trim these back to the branches they stem from as well. If there’s not much space within the canopy for light to reach the center of the tree, you can trim away some excess foliage to make windows for light to shine in.

For healthy growth, make sure that Great basin bristlecone pine 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.

Great basin bristlecone pine 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.

Great basin bristlecone pine 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 Great basin bristlecone pine during extreme weather events.

While bright morning sun and some full sun exposure can be highly beneficial for Great basin bristlecone pine, 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 Great basin bristlecone pine 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 Great basin bristlecone pine 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 Great basin bristlecone pine 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 Great basin bristlecone pine 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. Great basin bristlecone pine fresh from a nursery is also usually not prepared for strong full sunlight and must be introduced to it slowly.

Recently transplanted Great basin bristlecone pine 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 Great basin bristlecone pine 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.

Great basin bristlecone pine 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.

As a cool-weather plant, Great basin bristlecone pine has a specific temperature range you can keep it in to thrive. For Great basin bristlecone pine to grow as well as possible, you can keep them between 65-75℉(18-25℃). Great basin bristlecone pine can handle temperatures outside of this range, but whenever possible, try to keep the area you grow them in within several degrees of these temperature limits.

As for the upper and lower limits of what Great basin bristlecone pine can withstand, that would fall between 75-85℉(25-30℃) on the higher end and 5℉(-15℃) on the lower end. As Great basin bristlecone pine prefers cooler temperatures, the higher temperature range is more important to avoid. Going into the higher end temperatures can restrict growth, and having Great basin bristlecone pine above 85℉(30℃) for long periods of time can result in damage and eventually death.

For each growing phase of Great basin bristlecone pine, temperatures should be kept within the optimal range of 65-75℉(18-25℃). Great basin bristlecone pine can tolerate lower temperatures better than high ones, so it won’t particularly hinder growth if your growing area gets as cold as 5℉(-15℃). Below that, however, can start to slow down Great basin bristlecone pine growth, so if you continue to grow your plants into winter, make sure to keep the room above that temperature.

Tip #1: Watch for the Signs of Heat Damage

If Great basin bristlecone pine overheats, there may be warning signs before it begins to die off. First, the leaves may begin to brown, then branches could begin to fall off. This is because the branches themselves are dying as the tree pulls moisture back towards its center of mass. Make sure to keep temperatures lower, and water your Great basin bristlecone pine more frequently if they are exposed to heat.

Tip #2: Don’t Let Great basin bristlecone pine Get Too Cold

While Great basin bristlecone pine does prefer cooler environments, letting the temperatures drop too fast can begin to cause freeze damage. If your growing area dips fast below 5℉(-15℃), the water in your Great basin bristlecone pine can begin to freeze. This causes the cell walls to burst and the bark to crack. This could slow growth significantly, and if temperatures don’t increase, may begin to cause parts of Great basin bristlecone pine to die.

Tip #3: Use Shade and Ventilation to Help Keep Temperatures at the Right Level

If you find that Great basin bristlecone pine is starting to overheat, you can use a combination of shade and ventilation to help bring temperatures back down. If you don’t have access to an air conditioning unit or fans, shade and ventilation are a good cost effective way to bring temperatures back into the optimal range. Once temperatures are corrected, though, make sure to let your plants get sunlight. Great basin bristlecone pine needs a lot of sun to grow properly, so while shade could work in the short term for temperature correction, Great basin bristlecone pine should not be left in the shade for too long.

The only time you need to worry about different temperatures in different seasons is if you intend to grow Great basin bristlecone pine outside. In that case, you’ll want to watch your outdoor thermometer during the prime growing seasons, spring and early summer. It's especially important that the temperatures do not exceed 85℉(30℃), as this can damage and eventually kill Great basin bristlecone pine.

If you do plant them inside to help maintain the best temperature, make sure that the space has ample sunlight. Great basin bristlecone pine needs a lot of sun to grow, preferring full sun to partial shade levels of sun exposure. Be careful that the level of sunlight doesn’t raise the temperature as well. Direct sunlight is important, but too much combined with high heat will begin to damage Great basin bristlecone pine.

The best way to maintain the right temperature for Great basin bristlecone pine is to grow them within a climate-controlled environment. Because Great basin bristlecone pine prefers cooler conditions, you’ll want to make sure the room you choose has air conditioning or fans, as well as a way to monitor the temperature. Check the temperature once or twice a day, making sure that it is between 65-75℉(18-25℃). If it isn’t, adjust your climate control settings to make sure that the temperatures sit within that range.

If you intend to grow Great basin bristlecone pine outdoors, you’ll want to do it in the spring and early summer. It can be much harder to maintain that optimal temperature range outside, so if you want to facilitate maximum growth for Great basin bristlecone pine, it's usually best to have them outdoors.

Fertilizing Great basin bristlecone pine 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, Great basin bristlecone pine is a little different from your garden annuals and perennials. It doesn’t require a lot of extra nutrients. The best time to fertilize Great basin bristlecone pine is in the spring before new growth appears.

Some plants thrive with monthly or weekly fertilization, but not Great basin bristlecone pine. 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 Great basin bristlecone pine 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 Great basin bristlecone pine 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 Great basin bristlecone pine 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.
