What is the best way to water my Square bamboo?

Your Square bamboo will not be too picky about how you choose to water it. As such, you can use just about any common watering tool to moisten this plant’s soil. Watering cans, hoses, and even cups will work just fine when it is time to water your Square bamboo. Regardless of which watering tool you use, you should typically apply the water directly to the soil. In doing so, you should ensure that you moisten all soil areas equally to give all parts of the root system the water it needs. It can help to use filtered water, as tap water can contain particles that are harmful to plants. It is also beneficial to use water that is at or slightly above room temperature, as colder or hotter water can be somewhat shocking to the Square bamboo. However, the Square bamboo usually responds well to any kind of water you give it.

What should I do if I water my Square bamboo too much or too little?

For outdoor plants, especially newly planted plants or plant seedlings, they can be prone to lack of watering. Remember that you need to keep watering enough for a few months when the tree is small or just planted. This is because once the roots are established, Square bamboo can rely on rain most of the time. When your Square bamboo is planted in pots, overwatering is often more likely to.When you accidentally overwater your Square bamboo, you should be prepared to remedy the situation immediately. First, you should stop watering your plant right away to minimize the effect of your overwatering. After, you should consider removing your Square bamboo from its pot to inspect its roots. If you find that none of the roots have developed root rot, it may be permissible to return your plant to its container. If you do discover signs of root rot, then you should trim away any roots that have been affected. You may also want to apply a fungicide to prevent further damage. Lastly, you should repot your Square bamboo in soil that is well-draining. In the case of an underwatered Square bamboo, simply water this plant more frequently. Underwatering is often an easy fix. If you underwater, the plant's leaves will tend to droop and dry out and fall off, and the leaves will quickly return to fullness after sufficient watering. Please correct your watering frequency as soon as underwatering occurs.

How often should I water my Square bamboo?

Most plants that grow naturally outdoors can be allowed to grow normally with rainfall. If your area lacks rainfall, consider giving your plants adequate watering every 2 weeks during the spring and fall. More frequent watering is needed in summer. In winter, when growth becomes slower and plants need less water, water more sparingly. Throughout the winter, you may not give it additional watering at all. If your Square bamboo is young or newly planted, then you should water more frequently to help it establish, and mature and grow up to have more adaptable and drought tolerant plants. For potted plants, there are two main ways that you can determine how often to water your Square bamboo. The first way is to set a predetermined watering schedule. If you choose this route, you should plan to water this plant about once every week or once every other week. However, this approach may not always work as it does not consider the unique conditions of the growing environment for your Square bamboo . Your watering frequency can also change depending on the season. For instance, a predetermined watering schedule will likely not suffice during summer when this plant's water needs are highest. An alternative route is to set your watering frequency based on soil moisture. Typically, it is best to wait until the first two to four inches of soil, usually ⅓ to ½ depth of the pots, have dried out entirely before you give more water.

How much water does my Square bamboo need?

When it comes time to water your Square bamboo, you may be surprised to find that this plant does not always need a high volume of water. Instead, if only a few inches of soil have dried since your last watering, you can support healthy growth in the Square bamboo by giving it about five to ten ounces of water every time you water. You can also decide your water volume based on soil moisture. As mentioned above, you should note how many inches of soil have dried out between waterings. A surefire way to make sure your Square bamboo gets the moisture it needs is to supply enough water to moisten all the soil layers that became dry since the last time you watered. If more than half of the soil has become dry, you should consider giving more water than usual. In those cases, continue adding water until you see excess water draining from your pot’s drainage holes. If your Square bamboo is planted in an area that gets plenty of rain outdoors, it may not need additional watering. When the Square bamboo is young or just getting established, make sure it gets 1-2 inches of rain per week. As it continues to grow and establish, it can survive entirely on rainwater and only when the weather is hot and there is no rainfall at all for 2-3 weeks, then consider giving your Square bamboo a full watering to prevent them from suffering stress.

How can I tell if i'm watering my Square bamboo enough?

Overwatering is a far more common problem for the Square bamboo, and there are several signs you should look for when this occurs. Generally, an overwatered Square bamboo will have yellowing leaves and may even drop some leaves. Also, overwatering can cause the overall structure of your plant to shrivel and may also promote root rot. On the other hand, an underwatered Square bamboo will also begin to wilt. It may also display leaves that are brown or brittle to the touch. Whether you see signs of overwatering or underwatering, you should be prepared to intervene and restore the health of your Square bamboo.

How can I water my Square bamboo at different growth stages?

When the Square bamboo is very young, such as when it is in a seedling stage, you will need to give it more water than you would if it were at a mature age. During the early stages of this plant’s life, it is important to keep the soil consistently moist to encourage root development. The same is true for any Square bamboo that you have transplanted to a new growing location. Also, the Square bamboo can develop showy flowers and fruits when you give them the correct care. If your Square bamboo is in a flowering or fruiting phase, you will likely need to give a bit more water than you usually would to support these plant structures.

How can I water my Square bamboo through the seasons?

The seasonal changes will affect how often you water your Square bamboo. Mainly, during the hottest summer months, you will likely need to increase how much you water this plant, especially if it grows in an area that receives ample sunlight. Strong summer sunlight can cause soil to dry out much faster than usual, meaning that you’ll need to water more frequently. By contrast, your Square bamboo will need much less water during the winter, as it will not be in an active growing phase. During winter, you can get by with watering once every 2 to 3 weeks or sometimes not at all. For those growing this plant indoors, you should be somewhat wary of appliances such as air conditioners, which can cause your plant to dry out more quickly, which also calls for more frequent watering.

What's the difference between watering my Square bamboo indoors vs outdoors?

In some cases, your Square bamboo may not need any supplemental watering when it grows outside and will survive on rainwater alone. However, if you live in an area of little to no rain, you should water this plant about every two weeks. If you belong to the group of people who live out of this plant's natural hardiness zone, you should grow it indoors. In an indoor setting, you should monitor your plant's soil as it can dry out more quickly when it is in a container or when it is exposed to HVAC units such as air conditioners. Those drying factors will lead you to water this plant a bit more often than if you grew it outdoors.

How can I prune my Square bamboo?

Pruning your Square bamboo is a fairly simple process. First, you will need a reliable set of hand pruners or hedge trimmers. You may use a clean pair of sharp scissors if you don’t have pruners or garden shears on hand. It’s important to always clean your gardening tools before and after using them to prevent the possibility of spreading disease or infection to other plants. To prune your Square bamboo simply allow your plant to go dormant over the Winter. Some time between late winter and early spring – or when new growth starts to appear – take your clean pruners or trimmers and cut away any dying, damaged, yellow or declining foliage. Repeat this process until you reach the base of the plant or until there are no dead pieces left to cut. When pruning, be careful not to damage the new growth that may be emerging near the base of your plant. These parts cannot be restored and pruning can increase the ventilation of the plants and facilitate their growth. Any pruning that is done to this plant should be cut straight across the blades or stems. No angled cuts are required. Diseased leaf blade foliage can be removed as it appears. This could be done anytime when your Square bamboo is growing.

What should I do after pruning my Square bamboo?

Once you’ve pruned your plant, you should dispose of the stems and leaves either by composting the healthy ones or throwing out the diseased parts. You can also fertilize just before or after pruning, which gives Square bamboo a little vitamin boost that can provide it the nutrients needed to better protect itself from any nearby pathogens or diseases. Do not water the Square bamboo immediately after pruning as this can lead to fungal infestation of the plants through the wounds. You don’t need much after care when you’re done pruning. It might benefit from light watering and some liquid plant food to encourage new growth.

How can I prune my Square bamboo during different seasons?

Early spring and late winter are the best times to prune your Square bamboo on a large scale. If you want to control the size of your Square bamboo, you can prune them as you wish, but be careful not to prune more than a third of the size of the plant. Yellow and diseased leaves may appear during the summer months when the Square bamboo is growing vigorously and these types of leaves need to be pruned back immediately. These parts of the Square bamboo cannot be restored and pruning increases the ventilation of the plant and facilitates its growth.

When should I prune my Square bamboo through different stages of growth?

Strategic pruning is usually done at different times of the year or during certain stages of growth depending on the plant. However, knowing when to prune your Square bamboo depends on where you live and how established your plant is. For example, if your Square bamboo is a new resident, it’s a good idea to wait until the plant starts to grow back before you start pruning. On the other hand, if your plant is already established, you will want to prune the dry or dead parts in plant before new leafy growth appears in early spring or late winter. This is the time of year when plants are dormant and pruning causes the least damage to them. This is also the best time of year to do more extensive pruning. It’s important to note that if Square bamboo is pruned too late in the season, it can leave new growth at risk for damage or disease. However, if your Square bamboo is indoors this is not a problem and you can prune at any time. Since this can affect the long-term health and appearance of your plant, it’s important to keep this in mind when deciding when and how to prune. As your Square bamboo grows larger over time, you can trim it as needed after annual pruning. Dead, damaged, or diseased leaf blade foliage can be removed as it appears. This could be done anytime when your Square bamboo is growing.

What is the optimal temperature for Square bamboo?

Colder temperatures can affect plants since they have the same temperature as the air around them. When they are exposed to the sun, they can start to get warm again, but this is not the case during winter. The temperature range for the Square bamboo is often 70~85℉(21~30℃). They might tolerate 20~30℉(-6~0℃) even 15℉(-10℃), but not for long since this can result in frost damage. Maximum temperatures should be around 70~85℉(21~30℃), but make sure that you spray them with water from time to time and give them some shade to prevent wilting.

Should I adjust the temperature for Square bamboo during different growing phases?

Do some research and make sure that the temperature is right when growing Square bamboo. Some growers might consider decreasing the plants' thermostats during the growing season to reduce HVAC costs. However, it's vital to understand that the temperature can affect the flowering, pest management, and quality of the plants. There will be a temperature point where the Square bamboo will stop growing, and this can happen during the winter when some species might go into a dormant state. The base temperature becomes warmer when the season changes and the Square bamboo can grow faster. The species that are naturally growing in warm habitats have higher optimum temperatures when you compare them to the ones that thrive in a cooler climate. When the seeds of Square bamboo are exposed to cool temperatures, this can cause a decrease in uniformity and delays. You might also want to lower the temperature during flowering but not at other phases. Cooler temperatures at night will also require less water, so adjust the irrigation as needed.

How can I keep Square bamboo warm in cold seasons?

Stop fertilizing the plant to avoid new growth and allow the old ones to become hardy. This way, they can endure colder temperature when it begins to drop. To keep them warm, you can build structures around the Square bamboo like cages or trellises. There are also options to use heat mats that can gently warm the soil since they can consistently maintain an ideal temperature range for the Square bamboo.

How can I save Square bamboo from temperature damage?

During winter, you can protect the Square bamboo from frost by covering it with cloths, tarps, burlaps, sheets, or plastic buckets. Make sure to keep them down so they continue to act as insulators and the wind will not blow them away. However, ensure that the plastic sheets or burlap covers should not touch any part of the fruit or foliage, or the cold temperatures can transfer to the material and cause burns. When the temperatures begin to rise during the daytime, remove the covers.

Should I adjust the temperature for Square bamboo in different seasons?

When growing the Square bamboo in spring, you might want to increase humidity since the air temperature tends to be cooler at this time. A dry temperature can be a stressful growing environment for various species, which can help. If summer arrives, the large cover of the greenhouse and the warm temperature will mean that there will be a higher humidity level in the air. Some signs to look for are the condensation that is often found on the walls of the greenhouse, and this can cause issues with pollination and the development of infections when the water begins to fall on the leaves. Make adjustments according to the temperature and do some spraying during the hotter days of the year.

What damage will Square bamboo suffer if the temperature is too high/low?

Generally, the first cold snap can destroy the Square bamboo and others might go into a dormant state when the temperature is low. Some plants can get chilled when the temperatures range from 20~30℉(-6~0℃). They can freeze when the temperature begins to drop below 32℉(0℃). Those species that hide most of their parts under the soil might lose their structures above ground, but they can recover in spring. Some of the associated issues with too low temperatures are the lack of availability of resources like water, and nutrients, and those subtropical plants can suffer when the temperature reaches below 20℉(-6℃). The plants can also get damaged because of extreme heat stress when it's too high. This can reduce the transpiration rate that can affect the growth and productivity of Square bamboo.

What tips and cautions should I keep in mind when it comes to temperature for Square bamboo?

You need to cover the plants at night since these can add about 5 degrees more to protect the species from frost and freezing temperatures. The cloth rows can work well as blankets and ensure that there are no openings where the heat could escape. When using the covers, avoid the plastic from touching the foliage because this can cause the Square bamboo to freeze. Remember to keep the covers during the day and stop using heat pads during the summer. It will always be worth the effort to protect the cold-intolerant plants from freezing temperatures to help them survive.

How can I keep Square bamboo warm without a heat pad?

If you prefer not to use a heat pad, bring the Square bamboo inside, especially if it's freezing outdoors. During spring, consider the ones you need to bring indoors and plant them in moveable pots and containers.

How can I provide Square bamboo with an adequate temperature condition?

Most often, the ones caring for the Square bamboo will grow them in greenhouses. This is because they can provide adequate temperature in these areas that won't affect the photosynthesis process of a specific process. Some install the proper HVAC systems to control the temperatures of Square bamboo. This can handle many species' cooling and heating needs, especially during the summer and winter. They generally place the cooling or heating pad under the plants rather than above to achieve their desired temperatures. If outdoors, you can protect the Square bamboo from frost by covering it with cloths, tarps, burlaps, sheets, or plastic buckets.

Under what conditions should I stop adjusting the temperature for Square bamboo?

Heat mats are often left on Square bamboo to set the temperatures at a more consistent level. When the weather becomes warmer during the day, you can remove them, especially if the species are exposed to the sun. Put the pads away once the plants are established and when they start growing flowers and fruits.

Why do I need to fertilize my Square bamboo?

Regardless of which kind of Square bamboo 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 Square bamboo be more resilient to tough growing conditions while also gaining a better ability to fight off diseases and pests. The foliage of your Square bamboo 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 Square bamboo. Doing so will prompt your Square bamboo to develop leaves with a deep color and a lush overall look.

When is the best time to fertilize my Square bamboo?

The first time that you should fertilize your Square bamboo is during the late winter or early spring. This type of fertilization gives your Square bamboo all the nutrients it needs to resume healthy growth once the weather gets warm enough. It is also beneficial to many Square bamboo 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 Square bamboo will use in the following growing season, but it also helps your Square bamboo 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.

When should I avoid fertilizing my Square bamboo?

There are a few times during the year when you should not fertilize your Square bamboo. The first time occurs during the early and mid-winter months, during which time your Square bamboo 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 Square bamboo 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.

What type of fertilizer does my Square bamboo need?

In most cases, the most important nutrient for a Square bamboo is nitrogen, but that does not mean that phosphorus and potassium are unimportant. On the contrary, your Square bamboo 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 Square bamboo. 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.

How do I fertilize my Square bamboo?

To fertilize your Square bamboo 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 Square bamboo, 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 Square bamboo. At times, it is beneficial to perform a soil test before fertilizing to see if you will need to alter the pH at all.

What happens if I fertilize my Square bamboo too much?

Overfertilization is always a risk when you are feeding a Square bamboo. 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 Square bamboo may begin to develop brown leaves. Your Square bamboo can also show stunted growth in some cases. On the other hand, it is also possible that too much fertilizer can prompt your Square bamboo 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 Square bamboo.

Common Pests & Diseases About Square bamboo

Feedback

Common issues for Square bamboo based on 10 million real cases

Leaf scorch

Leaf blight causes leaves to dry out and turn brown starting at their tips.

Solutions: The solution to leaf scorch will depend on the cause, however, in general all cultural care methods that improve plant health and root functionality will reduce symptoms. Mulching the root zone (preferably with wood chip mulch) helps retain moisture, reduce evaporation, and promotes a healthy, functional root environment that is critical for water movement to the leaves. Check the root collar for girdling or circling roots that strangle the trunk and limit water and nutrient movement. Protect trees from severe root damage of nearby construction and excavation. If fertilizer burn is to blame, irrigate the soil deeply to flush out excess fertilizer salts. However, keep in mind that fertilizer runoff is an environmental pollutant. Avoiding excess fertilization in the first place is the best approach. If soil testing has revealed a potassium deficiency, apply a potassium fertilizer and water well. Even if you have enough potassium in the soil, plants will not be able to take it up if the soil is consistently too dry. Severely affected twigs may be removed using a pair of sharp and sanitized pruning shears, as weakened branches are susceptible to secondary infections. If your plant has bacterial leaf scorch, there is no cure. Antibiotic injections applied by a professional can reduce symptoms for a season, however, the above cultural management methods are the best options to reduce symptoms and prolong life. An infected plant will likely die within ten years.

Leaf tips withering

Low air humidity can cause the edges of the leaves to dry out.

Solutions: If your plant has only a few dried tips, complete the following: Increase humidity. Increase the humidity around your plant by misting it with a spray bottle daily. Alternatively, you can use a humidifier. Water plant. If your soil is dry, water until the soil is moist but not damp. Water again when soil dries out. If a large portion of the leaves is suffering from dry tips, complete the following: Prune away affected tissue. Using sharp and clean pruning shears, remove the dried out tips using clean cuts to avoid harming healthy tissue. Plant tissue will heal on its own, but you can apply a pruning seal for extra protection.

Plant dried up

The entire plant may dry out due to dieback or normal seasonal dormancy.

Solutions: The solution for a dried out plant depends on the cause, so determine the cause before selecting a treatment method. Adjust your watering: Stick your finger in the soil near the roots. If it feels bone dry or overly saturated, you need to adjust your watering frequency accordingly. Prune back dead foliage: Snip off any brown stems and leaves on the plant to make space for new growth. This encourages the roots to send up fresh stems. Move to a proper environment. This may involve decreasing or increasing sun exposure, depending on the species. Decrease fertilizer applications. If you have applied too much fertilizer, you can repot plants with fresh potting soil. Wait. If your plant has dried out as daylight is decreasing, it is entering dormancy. Decrease watering and wait until the plant resumes growth.

Artificial lighting

Indoor plants require adequate lighting for optimal growth. When natural sunlight is insufficient, particularly in winter or in less sunny spaces, artificial lights offer a vital solution, promoting faster, healthier growth.
1. Choose the right type of artificial light: LED lights are a popular choice for indoor plant lighting because they can be customized to provide the specific wavelengths of light that your plants need.
Full sun plants need 30-50W/sq ft of artificial light, partial sun plants need 20-30W/sq ft, and full shade plants need 10-20W/sq ft.
2. Determine the appropriate distance: Place the light source 12-36 inches above the plant to mimic natural sunlight.
3. Determine the duration: Mimic the length of natural daylight hours for your plant species. most plants need 8-12 hours of light per day.

Important Symptoms

Symptoms of Insufficient Light in %s

Square bamboo is a versatile plant that thrives in full sunlight but can tolerate partial shade. While it can adapt to different light conditions, when grown indoors with insufficient light, subtle symptoms of light deficiency may arise.

(Symptom details and solutions)

Small leaves

New leaves may grow smaller in size compared to the previous ones once they have matured.

Leggy or sparse growth

The spaces between leaves or stems of your Square bamboo may become longer, resulting in a thin and stretched-out appearance. This can make the plant look sparse and weak, and it may easily break or lean due to its own weight.

Faster leaf drop

When plants are exposed to low light conditions, they tend to shed older leaves early to conserve resources. Within a limited time, these resources can be utilized to grow new leaves until the plant's energy reserves are depleted.

Slower or no new growth

Square bamboo enters a survival mode when light conditions are poor, which leads to a halt in leaf production. As a result, the plant's growth becomes delayed or stops altogether.

Lighter-colored new leaves

Insufficient sunlight can cause leaves to develop irregular color patterns or appear pale. This indicates a lack of chlorophyll and essential nutrients.

Solutions

1. To optimize plant growth, shift them to increasingly sunnier spots each week until they receive 3-6 hours of direct sunlight daily, enabling gradual adaptation to changing light conditions.2. To provide additional light for your plant, consider using artificial light if it's large or not easily movable. Keep a desk or ceiling lamp on for at least 8 hours daily, or invest in professional plant grow lights for ample light.

Symptoms of Excessive light in %s

Square bamboo thrives in full sun exposure but can adapt to partial shade. Although sunburn symptoms occur occasionally, they are generally tolerant of different light conditions due to their resilience.

(Symptom details and solutions)

Chlorosis

Chlorosis is a condition where the plant's leaves lose their green color and turn yellow. This is due to the breakdown of chlorophyll from excessive sunlight, which negatively affects the plant's ability to photosynthesize.

Sunscald

Sunscald occurs when the plant's leaves or stems are damaged by intense sunlight exposure. It appears as pale, bleached, or necrotic areas on the plant tissue and can reduce the plant's overall health.

Leaf Curling

Leaf curling is a symptom where leaves curl or twist under extreme sunlight conditions. This is a defense mechanism used by the plant to reduce its surface area exposed to sunlight, minimizing water loss and damage.

Wilting

Wilting occurs when a plant loses turgor pressure and its leaves and stems begin to droop. Overexposure to sunlight can cause wilting by increasing the plant's water loss through transpiration, making it difficult for the plant to maintain adequate hydration.

Leaf Scorching

Leaf scorching is a symptom characterized by the appearance of brown, dry, and crispy edges or patches on leaves due to excessive sunlight. This can lead to a reduction in photosynthetic capacity and overall plant health.

Solutions

1. Move your plant to the optimal position where it can receive abundant sunlight but also have some shade. An east-facing window is an ideal choice as the morning sunlight is gentler. This way, your plant can enjoy ample sunlight while reducing the risk of sunburn.2. It is recommended to trim off any completely dehydrated or withered parts of the plant.

Essentials

Regional wintering strategies

Square bamboo has some cold tolerance and generally does not require any additional measures when the temperature is above {Tolerable_growing_temperature_min}. However, if the temperature is expected to drop below {Tolerable_growing_temperature_min}, it is necessary to take some temporary measures for cold protection, such as wrapping the plant with plastic film, fabric, or other materials. Once the temperature rises again, the protective measures should be removed promptly.

Important Symptoms

Symptoms of Low Temperature in Square bamboo

Square bamboo has moderate tolerance to low temperatures and thrives best when the temperature is above {Suitable_growth_temperature_min}. During winter, it should be kept above {Tolerable_growing_temperature_min}. When the temperature falls below {Limit_growth_temperature}, the leaves may start to droop. In mild cases, they can recover, but in severe cases, the leaves will wilt and eventually fall off.

Solutions

Trim off the frost-damaged parts. Prior to encountering low temperatures again, wrap the plant with materials such as non-woven fabric or cloth, and construct a wind barrier to protect it from the cold wind.

Symptoms of High Temperature in Square bamboo

During summer, Square bamboo should be kept below {Suitable_growth_temperature_max}. When the temperature exceeds {Tolerable_growing_temperature_max}, the color of the leaves becomes lighter, the leaf tips may become dry and withered, the leaves may curl, and the plant becomes more susceptible to sunburn.

Solutions

Trim away the sunburned and dried-up parts. Move the plant to a location that provides shade from the midday and afternoon sun, or use a shade cloth to create shade. Water the plant in the morning and evening to keep the soil moist.
