Misting can be a good way to keep the leaves hydrated but not too soggy. Always make sure that there's good drainage to prevent root rot. The plant can be sensitive to fluoride, which is often common in the public water supply, and this species does not tolerate hard water, especially if it's in its growing stages.

Use a watering can or a sprinkler with purified or distilled water. Make sure to evenly water the entire surface of the soil so the stems won't rot. Use distilled water from time to time to avoid the death of the plant, leaf burn, or stunted growth instead of tap water. Another option is to utilize rainwater whenever it's available. Keep the soil moist every time but prevent it from being too soggy if the Joshua Tree is planted in a pot.

If it's outside planted in your garden, you need to have proper drainage and allow the soil to dry completely before you turn on the sprinkler or the garden hose, as this can lead to root rot and yellowing leaves.

Some use hydrogen peroxide as a treatment in the water, but this is not recommended for regular use. The hydrogen peroxide will stimulate rainwater but only do this occasionally. A filtration system might also be valuable for removing nitrates, salt, and lead that might be contained in the water.

Some signs that the plants are not getting enough water are the brown tips on the plant. These species are very sensitive to boron and fluoride that are usually found in tap water, and you might be able to see that they have too much of the minerals when the leaves begin to droop.

When the Joshua Tree is underwatered, the stems also show wrinkles.

The leaves can become brown, crispy, and start to dry out. When this happens, water as soon as possible.

Another thing about overwatering is that if this happens, then root rot can begin to set in. You need to remove all the damaged roots from the soil, especially if they appear mushy, fragile, and black. To help with these issues, it's important to cut off a larger part of the root.

Overwatering can also leave the leaves looking brown and ready to fall off. This can happen very early, so you should drain the excess water and wait for the soil to dry before watering to help the plant recover.

Throw away the soil from the pot if there are signs of root rot. Clean everything thoroughly and make sure to put in the pebbles so it will help with proper drainage. Discard any excess water at the base of the pot if you notice tan rings or reddish-brown spots on the leaves.

The Joshua Tree is a relatively tough species that is pretty tolerant to drought. This is why you need to water this only about every 1-2 weeks when you feel the soil is bone dry, especially if it is planted in a pot. Water generously until you see that the water begins to trickle down the pot's drainage holes. Make sure to remove the water from the saucer after an hour, and don't let it stand on the pot.

When they are planted in your garden, you need to consider the rainfall the plant is receiving. The roots don't like to sit in the water, so make sure to have proper irrigation as part of the landscape. Water 1 time every 2 weeks, especially if you live in a tropical area with plenty of rain and monsoons.

As a general rule of thumb, you should water Joshua Tree when you notice that about 2 inch of the top soil is already dry, especially when you grow it outdoors. When planted in the garden, you need to make sure that the Joshua Tree is getting its watering needs at least once every two weeks. There’s rainwater, seasonal changes, and moisture around the environment to consider so never overwater.

This can also apply when the pot is approximately 2 inches dry when it is grown indoors. If they are inside the house or grown in the nursery, try watering more frequently at least once a week since they might not be able to get the rainwater or extra moisture that they need indoors. As long as you notice that the plant leaves are sagging, then don’t hesitate to give them a drink.

The roots should be kept moist but not soggy. The best way to water them is to soak the pot and allow the water to drain. Make sure to water only when the soil is partially dry, and don't give them a specific schedule. They are not very thirsty plants, so wait a couple of days before giving them a drink. Well-draining soils can also help them grow and always put them in place with high humidity.

Water them every 1 to 2 weeks during the summer when it’s very hot outside. During the growing season and in spring, use the same amount of water as well. They need a lot of water when they are growing so you might want to give them a drink regularly.

If it’s winter or fall, know that you should only water every 2 to 4 weeks. This is when you notice that the soil is completely dried out.

Most of the time, schedules of bi-weekly or weekly watering should be more than enough for the Joshua Tree. Wait until the soil is 2 to 4 inches dry, especially if you have adult plants, to avoid excess watering. Pour generously until you see that the water comes out of the drainage holes. No standing water should be allowed, and remove the excess from the saucers. Root rot can happen if there's too much water, so it's always better to give too little than too much for this species.

The soak and dry method is more than enough for the plants whether they are indoors or outdoors. The soil around the plant should be completely soaked and make sure to record on an app or in your calendar each time you water. Allow the soil to dry to prevent root rot and help them develop a healthier root system. Water with a sprinkle or a can deep enough to reach the roots to prevent the plant from wilting.

The soil bed or the pots should be moist during the spring or fall. However, prevent them from getting soggy. Reduce watering during winter or towards the end of the fall. Remember that soil that's too dry or too wet might result in plant issues.

Allow the Joshua Tree to dry out before watering, especially in the winter. When there's too much dryness in the soil, use distilled water and saturate them thoroughly. Avoid cold water as much as possible. Occasional misting during the summer or the winter, as well as fertilizer in the spring, can help.

Water at least twice a week during its growing season, and you'll find that they can grow quicker. When they are in their early stages, the Joshua Tree is very sensitive to the minerals in tap water, so it's best to expose them to rainwater or filtered water.

While they are young, exposure to unnecessary chemicals can result in stunted growth and discoloration. A balanced fertilizer and watering whenever the soil is dry can help during the growing season.

In the growing season, the watering should be 1 to 2 times a week. When it's already established, you might want to water it once every 3 weeks. When you report a grown Joshua Tree, you need to water the soil well to make it damp. You can also wipe the leaves with a wet cloth to keep the insects away and to help them have more humidity during summer.

Depending on the location of the plants, it's best to water them frequently when they are indoors. Just make sure that they are far away from any heating appliances. The natural humidity of the room can be enough, but the plant might prefer the high humidity outdoors during the summer, especially if it resembles that of a rainforest's habitat.

Water the plants once every two weeks and lightly mist them at least thrice every seven days to keep them healthy if they are planted in a pot. One way of checking it is by removing the pot and seeing if the roots are already dry. This is possible with plastic pots, but you can always check with a moisture meter if you can't remove the pot.

When grown outdoors, you need to consider the plant's rainwater, especially in spring and summer. You might want to water this once every 1-2 weeks during the summer.

Avoid watering this during the late fall and winter, and only provide them a drink when you see brown spots on the leaves. They only need occasional watering when planted in your garden, and you need to transplant them indoors so they can survive the cool conditions during the winter. Some use a lot of mulch during the fall, but when growing in a cold zone, you should consider digging it and transplanting it, watering it occasionally, and waiting for the frost to pass.

The Joshua Tree loves high humidity and thrive in it. However, winter is when the humidity is low, and the indoor ones are more susceptible to wilting. Lightly mist the leaves with sprays so you can maintain the healthy growth of the plant in the spring and summer. It would also help to place the plants on trays that are filled with water and pebbles to create humidity around the Joshua Tree during winter but make sure to drain the saucer afterwards.

A high-quality humidifier might also help during winter. Also, use cold water on the plants during winter as this can cause permanent damage and root shock. Allow the water to warm at room temperature before you put it on the plants. Using heating appliances can dehydrate indoor air, so you might want to add more mist.

Place the pots near it and let them absorb the mist. Use bottled distilled water whenever possible since these are sensitive to fluoride. When you notice that the tips begin to turn yellow, this is where you might want to do the light misting several times a week.

Another thing is when you're using tap water from the local supply, just let it sit overnight. This will reduce chlorine and other chemicals that might be mixed into the water. Distilled water is always the best alternative.

During the summer, be careful with overwatering. The brown tips suggest that there's not enough moisture in the air, and you should add some when the Joshua Tree shows an indication that it’s thirsty.

Watering the Joshua Tree will help them grow beautiful foliage. This species can bring beauty all year round, and you might want to ensure that the leaves remain green regardless of the season.

Watering it according to its needs can prevent many problems often associated with too much soil moisture. You can prevent root rot, fungal diseases, and brown tips on the potted plants and those planted on the ground.

It's best to use a watering can with tepid water when you notice that the soil is dry on the ground and in the pot. Use lukewarm water and look for signs of yellow foliage. The yellowing leaves are typically a sign that this species needs water. On the other hand, the brown tips indicate that you might be overwatering, so it's best to stop and give the soil time to dry regardless of whether they were planted outdoors or indoors.

Joshua Tree, 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 Joshua Tree 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 Joshua Tree to neglect them. Aside from keeping your Joshua Tree happier and healthier, pruning just makes things look nice and tidy. Who doesn’t love a well-kept tree, anyway?

Joshua Tree 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 Joshua Tree 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 Joshua Tree, it’s best to wait until those same colder months when outdoor Joshua Tree wouldn’t normally be actively growing. Joshua Tree 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 Joshua Tree 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 Joshua Tree 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, Joshua Tree!

While most of the Joshua Tree 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 Joshua Tree needs to be pruned in good time. Tools In order to prune your Joshua Tree 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 Joshua Tree, 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 Joshua Tree 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.

Joshua Tree 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.

Joshua Tree 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 Joshua Tree during extreme weather events.

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

Recently transplanted Joshua Tree 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 Joshua Tree 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.

Joshua Tree 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 Joshua Tree 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 Joshua Tree 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.

Joshua Tree 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 Joshua Tree if the temperature is consistently too high versus too low.

If Joshua Tree 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 Joshua Tree 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 Joshua Tree 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 Joshua Tree, 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 Joshua Tree 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 Joshua Tree 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 Joshua Tree 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.

Joshua Tree 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 Joshua Tree in a shaded location and water often to keep the soil moist.

Regardless of which kind of Joshua Tree you own, regular fertilization will help you grow a plant that has great overall health. The proper supply of nutrients leads to more vigorous growth and can help your Joshua Tree be more resilient to tough growing conditions while also gaining a better ability to fight off diseases and pests.

The foliage of your Joshua Tree is one of its most attractive features, which is why you should do all you can to keep it intact. Again, this means creating and adhering to a regular fertilization schedule that is specific to your Joshua Tree. Doing so will prompt your Joshua Tree to develop leaves with a deep color and a lush overall look.

The first time that you should fertilize your Joshua Tree is during the late winter or early spring. This type of fertilization gives your Joshua Tree all the nutrients it needs to resume healthy growth once the weather gets warm enough.

It is also beneficial to many Joshua Tree to provide an additional fertilizer feeding during early fall if you in a warm climate region. Fertilizing in early fall not only adds additional nutrients to the soil, which your Joshua Tree will use in the following growing season, but it also helps your Joshua Tree be a bit more hardy and capable of surviving the winter cold without experiencing foliage damage. Earlier fertilisation will ensure that the new branches have enough time to grow to withstand the cold winter.

There are a few times during the year when you should not fertilize your Joshua Tree. The first time occurs during the early and mid-winter months, during which time your Joshua Tree will be dormant and in no need of feeding.

It is also unwise to fertilize this plant during the late spring and all of the summer. During that time of year, the weather will likely be hotter and can be much dryer as well. Both conditions make it more likely that your Joshua Tree will have a very negative response to fertilization. To avoid such issues, stick to a fertilization schedule that involves feeding exclusively during early spring and early fall.

In most cases, the most important nutrient for a Joshua Tree is nitrogen, but that does not mean that phosphorus and potassium are unimportant. On the contrary, your Joshua Tree likely needs a decent amount of all three main nutrients, which is why a balanced fertilizer, such as a 10-10-10, can work well.

However, a more nuanced ratio of nutrients often leads to optimal growth for a Joshua Tree. Often, fertilizers that are a bit higher in nitrogen work a bit better. For example, a ratio of 10-6-4 can often work well. When fertilizing, you can use a granular fertilizer or a liquid-based one.

To fertilize your Joshua Tree using a granular fertilizer, all you need to do is sprinkle the fertilizer on the soil at the correct time. The slow-release nature of granular fertilizer will release nutrients into the soil slowly over time. As is usually the case, it's best to water your Joshua Tree, at least lightly, before applying fertilizer.

As an alternative, you can use a liquid fertilizer, but this is less common. To use this approach, mix your fertilizer with water, then pour the water onto the soil around the base of your Joshua Tree. At times, it is beneficial to perform a soil test before fertilizing to see if you will need to alter the pH at all.

Overfertilization is always a risk when you are feeding a Joshua Tree. Overfertilization is especially likely if you feed this plant at the wrong time of year, feed it too often, or feed it without watering the soil first.

When overfertilization takes place, your Joshua Tree may begin to develop brown leaves. Your Joshua Tree can also show stunted growth in some cases. On the other hand, it is also possible that too much fertilizer can prompt your Joshua Tree to rapidly produce too much new growth, much of which will be weak and prone to breaking. Weak new wood can also detract from the overall form and structure of your Joshua Tree.
