Watering Care

To prevent Spinach from going to seed, do not let the soil dry out. Keep the ground evenly moist, watering when it begins to dry out. Water close to the plant’s base to keep the moisture from splashing on the leaves.

Details on Watering Care

Fertilizing Care

Adding manure or compost along with an all-purpose granulated fertilizer to the garden bed before planting spinach encourages healthy roots and growth. A vegetable fertilizer can also be applied at planting time, and once again during the growing season.

What is the best way to water my Spinach?

Not only does the Spinach have certain preferences regarding how much water it receives, but it also cares deeply about how you provide that water. In fact, if you don't use the proper watering technique, you risk harming your tomatoes. The best way to water Spinach is to apply the water directly to the soil in a slow and gentle manner. You should not pour all of the water into the soil at once, and you should not do overhead watering for your Spinach. Although you should water slowly, you should also water deeply to ensure that all of the soil in which your Spinach grows is sufficiently moist.

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

If you find that you have overwatered your Spinach and you are concerned about the associated risk of disease, you should intervene immediately. Often the best approach for an overwatered Spinach is to uproot it from its current growing location. Once the plant is out of the ground, you can allow its roots to dry a bit before planting it in a new growing location. Ensure that the new growing location has soil with good drainage. If you grow in pots, you may also want to move your plant to a pot with more or larger drainage holes. In the case of underwatering, all you will need to do is increase the frequency with which you supply water to your plant.

How often should I water my Spinach?

Overall, Spinach requires a significant amount of water throughout the growing season. To meet that high water need, you'll need to water early and often throughout the spring and summer. During the earlier parts of the growing season, you should water your Spinach about once or twice per week. As the season progresses, you should increase your watering frequency. You may need to water it twice per day or more during summer, depending on the weather. After your Spinach have gone through their major seasonal growth phases, you can reduce the frequency of your watering to about once per week until the end of the growing season.

How much water does my Spinach need?

Since Spinach are incredibly popular, with many professional and amateur gardeners growing them successfully, we have a pretty clear idea of how to care for these plants. That understanding includes specific knowledge about the precise volume of water an average Spinach should receive. Generally, Spinach will require about 1 - 1.5 inches of water per week. That volume should be dispersed evenly through your weekly watering. As the weather gets warmer, you may need to supply more water, but in most cases, two inches per week is a good baseline amount.

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

Underwatering and overwatering can both occur as problems for your Spinach, and both these problems can manifest with similar symptoms. For example, foliage discoloration and wilting can both result from either overwatering or underwatering. When your Spinach is underwatered, its leaves will be curling and drooping at the beginning. You will see a bunch of leaves turn less vigorous. Underwatering is also likely to cause stunted growth and poor overall development as both the flowers and this plant require a high amount of water. Overwatering is more likely to lead to disease, including rot. Overwatering may also lead to unpleasant smells rising from your plant's soil. The symptoms of underwatering will show up quicker than overwatering. Overwatering can also be evident in soil conditions. Mainly, if you notice a lot of standing water or waterlogged soils, overwatering is likely to occur.

How should I water my Spinach through the seasons?

As alluded to above, your Spinach's water needs will repeatedly change throughout the seasons. During most of spring and summer, you should water your Spinach about once every week. As the heat of summer arrives, you should plan to increase your watering frequency to once or twice per day. In the late summer and fall, towards the end of the harvest period, you can reduce your watering frequency to about once per week. After harvest has ended, you can cease watering as your Spinach has reached the end of its life cycle and will require no further soil moisture.

The maintenance schedule of Spinach will require you to alter the amount of water you provide depending on the plant's current growth stage. Early on, especially if you grow your Spinach from seeds, you'll need to provide water often enough to maintain consistent soil moisture, which encourages root development. When the plant becomes old enough to produce flowers, it will likely need even more water. During the fruit development growth stage, your Spinach will likely need the most water out of any growth period, at times requiring water more than twice per day. Following that phase, the water needs of Spinach will decline significantly.

What's the difference between watering Spinach indoors and outdoors?

Whether you grow Spinach indoors or outdoors can also play a role in how you water them. Spinach that grows outdoors may receive water from natural rainfall, which will reduce the amount of supplemental water you should supply. However, it is incredibly rare for rainfall to adequately replace your watering entirely. Plants that grow indoors, along with any Spinach that grows in a container, will need to be watered more frequently than those that grow in the ground outdoors. If you choose this route, please make sure that the plant gets enough water by checking the soil moisture within your pot often to keep your Spinach healthy.

Is pruning necessary for my Spinach?

Spinach is a kind of annual plant so it doesn't need much pruning. You only need to cut off and clean the diseased, yellow or dropped leaves and stems during its growing period. This will help your Spinach to stay away from pathogens infection.

How do I prune my Spinach?

During the growth of the plant, yellowing, drying and spotted leaves are produced, and these spotted and discolored leaves need to be trimmed off. If the whole piece of leave is discolored or infected, you will need to cut it off completely. In other situations, you will only need to cut off the discolored or infected part on certain leaves. Spinach above the ground will die and dry up in the winter, and the dead plants need to be cleaned up.

Are there any cautions I should be careful with when pruning my Spinach?

Spinach leaves are delicate, so take care not to score or bruise them. Unless the leaves are withered or heavily discolored, do not prune the leaves from the lowermost branches unless they’re damaged. They typically grow the largest, so they supply the plant with critical energy to keep it growing right. Please prevent the wounds from water after pruning until they are fully recovered. Remember always sterilize the tools before pruning. When the pruning is finished, please throw all the waste leaves and stems into the trashbins to avoid diseases and bugs.

Are there any tips for pruning my Spinach?

Sterilize all the tools before pruning; unclean tools will pass pathogens to the plant through wounds;
Prune on sunny days because the new cuts will be infected by pathogens if they're distained by rain or water.
Throw all the waste leaves and stems into trashbins, they will easily rot and attract diseases and bugs

When should/shouldn't I prune my Spinach?

Expect to prune your Spinach every week if it’s growing well or every two weeks if it grows slowly. It is always good to prune it on sunny days because if you prune it on rainy days, the rainwater will distain the cuts and cause the whole plant to be infected.

What should I look for when pruning my Spinach in different seasons?

Because Spinach is an annual plant, the pruning should take place basically during the seasons that the plant grows rapidly. During the growth of the plant, yellowing, drying and spotted leaves are produced, and these spotted and discolored leaves need to be trimmed off.

How much sunlight does Spinach need to grow?

Exact needs vary, but a minimum of 6 to 8 hours per day is a good rule of thumb for Spinach to grow and produce fruit.

What type of sunlight does Spinach need?

Spinach requires full sun, meaning that it should be grown in a location that gets direct sunlight that isn’t blocked by obstacles such as trees, fences, or buildings. In general, the faster the plant grows, the more hours of sunlight it will need. Morning sun is best for photosynthesis.

Should I protect Spinach from sun exposure?

Spinach should not need to be protected from the sun in most climates. Those who live in a desert or near the equator may find that the sun is too harsh for the types of plants they want to grow, but this is the exception.

What will happen if Spinach doesn't get enough sunlight?

All plants need sunlight to convert into energy. Plants that have a short growing season need even more light and energy than those that grow slowly, as they need to complete all their processes to grow and produce fruit within just a few months.

The first symptoms of insufficient sunlight in Spinach are pale and yellow leaves that are not able to generate enough chlorophyll to keep their healthy green color. The leaves may eventually fall off, and new growth is small and weak. The plant may become leggy and sparse as it stretches toward the available light.

Finally, without enough light the plant will not be able to produce large, high-quality edible leaves or fruit. Spinach needs to devote a lot of energy into growing leaves and fruits, so if there isn’t enough light available for it to convert, the harvest will suffer.

What will happen if Spinach gets too much sunlight?

Spinach can get sunburned from intense sunlight, especially when coupled with high temperatures and not having enough water. Afternoon sun tends to be most likely to burn plants. Scalded leaves develop faded patches of light brown to white on the areas at the top of the plant that are exposed to the most sun. They are especially vulnerable to this right after being transplanted from a shadier location to being in full sun. Transitioning plants gradually or providing them with a barrier while they are adjusting can help prevent sunscald in young plants.

In many cases, Spinach develops leaves that are large enough to protect fruits from the strongest rays of the sun. However, if intense sunlight is in contact with fruits, they can also be damaged. Avoid over-pruning those protective leaves so that the fruits don’t get burned.

Are there any cautions or tips for sunlight and Spinach?

Spinach may become unbalanced if it gets significantly more light on one side than the other. Ideally, you can plant your Spinach in a location away from obstacles that might block light, and where the distribution of sunlight is even on all sides.

Be careful about planting tall species next to those that grow closer to the ground. It may not be obvious when the crops are first planted, but over time the taller plants may begin to block the amount of sunlight that can reach the shorter plants.

Morning sun helps to dry dew and precipitation, which helps prevent infection from diseases that can develop when water sits on the plant. If you are watering or irrigating your Spinach, this should be done in the morning.

What is the optimal temperature for Spinach?

There is an ideal temperature range that makes Spinach feel at home. Under these temperature conditions, it's unlikely that you’ll have any issues with cold or hot damage to the foliage, but changing leaf colors can absolutely be a sign that Spinach isn’t happy. Try to keep your Spinach well within its preferred range of 70-85℉(21-30℃), but don’t panic if the temperature creeps up past 85℉(30℃) during the day or down to 70℉(21℃) at night.

How can I protect Spinach from extreme temperatures outdoors?

If your Spinach happens to be planted outside, then there’s not much you can do to try to move it indoors. However, you can certainly provide cover in ways that will help it survive any extreme temperatures that may arise unexpectedly. For instance, you can always use a few stakes and some cloth to put together a shade tent that will block out much of the sun’s intense heat from direct sunlight exposure.

Similarly, Spinach can be protected from the extreme cold and especially chilly winds by building a small greenhouse around the plant, which will create a greenhouse effect and warm the plant up. This can be done using garden stakes and any sort of clear or translucent plastic you may have around; if you have greenhouse plastic such as polycarbonate laying around, this works perfectly. Remove the greenhouse once temperatures warm up to 40℉(10℃) at night.

Does Spinach need different temperatures in different seasons?

Generally speaking, Spinach needs to stay within its preferred temperature range all year long. However, that doesn’t mean that care should stay the same all year long. During the warmest months of the year, Spinach will need a little extra shade and a bit more of a breeze to help it cope with the hottest days. On the other hand, it may need to be moved away from chilly windows and doors during the cooler months in climates where temperatures drop below 40℉(10℃) at any point in the year.

What is the best way to maintain the right temperature for my Spinach?

Keeping your Spinach at the right temperature can be fairly simple. Depending on where you grow it, Spinach can be fairly easy to accommodate. For indoor growing, you can easily move the plant to different locations within your indoor space that best meet its temperature requirements. Avoid placing it near air conditioning vents, heaters, doors that open frequently, or drafty windows.

It is a little more difficult to control the temperature around your Spinach if it’s grown outside. Of course, if it’s planted in a pot, you can simply bring it indoors when the temperatures outside get too hot or too cold for Spinach, but otherwise, you may need to take different measures to protect it from extreme heat or cold that may damage it irreversibly. Try placing Spinach under cover to protect from both the harsh sun that can overheat it and any cold wind that could be potentially deadly for your plant.

Why do I need to fertilize my Spinach?

Spinach is grown for its edible leaves and shoots, so it needs sufficient nutrients to provide great flavor and a large harvest. If this plant is grown in soil that does not have enough nutrients, its leaves and stems will be underdeveloped, and flavors are likely to be inferior to a plant that is grown in more favorable conditions. Stems are likely to be thin and the taste may be bitter.

Fertilization is especially important if this plant is grown in a container, since container plants don't have as much access to organic matter as those grown in the ground. Supplement your Spinach with a balanced liquid fertilizer if it is grown in a pot.

When is the best time to fertilize my Spinach?

There are several points during the growing season that you should apply fertilizer to benefit your Spinach. The initial application occurs when you prepare the ground to be planted, at least 2 to 8 weeks before planting, amend the soil thoroughly with nutrient-rich organic material such as compost or manure.

Amend the soil again at planting time, using the same method. After your seedlings emerge, wait until they reach around 2 inches tall before applying the next dose of fertilizer. After that, you can continue to regularly feed your Spinach with rich organic matter or a commercial fertilizer until you harvest. A typical schedule would be to fertilize every two to three weeks. It is also a good idea to add a layer of compost or manure around the plant to provide a continuous supply of nutrients.

When should I avoid fertilizing my Spinach?

Avoid Fertilizing Spinach when soil conditions are dry. This plant requires plenty of water, and will not be able to properly absorb nutrients if there isn't enough moisture in the soil. Also avoid using chemical fertilizers on this plant outside of the growing season, since that risks introducing more fertilizer than the plant can use. Excess chemical fertilizer ends up in groundwater and can contaminate soil, so be sure to fertilize only during the active growing periods.

What type of fertilizer does my Spinach need?

Spinach should be provided with a balanced fertilizer, although it may not need much fertilization if the soil is rich enough. Organic fertilizers such as fish emulsion, well-rotted manure, and compost or compost tea work very well for growing Spinach.

You may prefer to use a fertilizer with a slightly higher nitrogen ratio compared to other macronutrients, as nitrogen supports strong foliage development. The NPK number on the fertilizer label will be the best way to understand the ratio of the three macronutrients nitrogen, phosphorus, and potassium in the mixture. The best way to determine what kind of fertilizer works best for Spinach in your garden is to perform a soil test and then compare the results against the requirements for successfully growing the plant.

How do I fertilize my Spinach?

Mix compost or other organic fertilizers into the soil prior to planting. This provides seedlings a great start so they can develop a healthy root system.

At the beginning of the growing season, layer compost or other organic fertilizers and soil amendments around the bed so they can release nutrients into the soil over time. A slow-release granular fertilizer can also be sprinkled onto the soil if needed to supplement nutrients and support leaf development. Liquid fertilizers could be used during the regular watering cycle, but be careful when using chemical fertilizer products that you do not use too much and burn your Spinach.

What happens if I fertilize my Spinach too much?

Overfertilization of Spinach can cause the plant to become stressed and burned. Spinach may die altogether, especially if excess fertilizer is combined with dry and/or hot conditions, so always remember to water thoroughly when fertilizing this plant.

Excess fertilizers cause a condition called fertilizer burn, which happens when too many salts build up in the roots or other parts of the plant. This is less common when using organic fertilizers compared to chemical fertilizers, so it is always recommended to use natural materials if possible.

Too much fertilizer causes the plant to become stressed, resulting in yellowing and wilting foliage. It is easier to avoid this condition than to treat it after it has already happened, but you can flush the soil with a lot of water if you have accidentally overfertilized. Spinach is resilient and can come back from unhealthy conditions once the problem is rectified.

Usages

Garden Use

Spinach is an annual plant prized for its ability to grow in the cooler months in the spring and fall. It is commonly used for its edible properties and is an essential plant in vegetable gardens. Plant it with cucumbers, tomatoes, peppers, squashes, and herbs for texture and a steady supply of fresh produce.

Trivia and Interesting Facts

Spinach is extremely rich in nutrients. However, care must be taken for at least three reasons: relatively high oxalate crystals content, which may damage kidneys in the long run, high vitamin K content which may be problematic for people with thrombophilias, and pesticides - spinach is one of the items with the highest pesticide residue content, so buying organic is recommended.

Common Pests & Diseases About Spinach

Feedback

Common issues for Spinach based on 10 million real cases

Leaf rot

Leaf rot in Spinach is a plant disease characterized by the decomposition of plant tissues, inducing immense distress in Spinach. The pathogens escalate the deterioration impacting the plant's photosynthesis capability, consequently affecting growth and potentially leading to plant death.

Leaf miners

Leaf miners is a term for larvae of insects that live in and consume the leaf tissue of plants. These pests cause significant damage to Spinach, leading to reduced growth, overall yield, and potentially death.

Caterpillars

Caterpillars are larvae of butterflies and moths that can drastically damage Spinach by eating its leaves, thus stunting plant growth. This often leads to a significant crop loss if not carefully managed.

Leaf beetles

Leaf beetles are a class of colored insects 1 to 2 cm in size. They gnaw on leaves and petals resulting in small, round holes scattered over the surface.

Solutions: For less serious cases: Remove beetles, nymphs, and eggs. Remove all life stages of the beetles and kill them by placing them in a bucket of warm, soapy water. This can be done more easily by placing the bucket under affected leaves and shaking the plant. This method is most effective in the afternoon when leaf beetles are more active. Always dispose of insects in a sealed bag or container to avoid escape and spread. To treat more serious infestations: Apply organic insecticides. Use naturally-derived insecticides before moving on to synthetic insecticides. Neem oil and pyrethrum are naturally-derived insecticides that should be applied following label instructions. Apply synthetic insecticides. Examples of insecticides effective for leaf beetles include carbaryl, permethrin, and bifenthrin. Apply insecticides according to label instructions.

Underwatering

Leaves may wilt for a variety of reasons.

Solutions: The easiest (and most obvious) way to address underwatering is to fully hydrate the plant. However, this must be done carefully. A common mistake that many gardeners make is to douse their underwatered plants with water. This can overwhelm the roots of the plant and shock its system, something that can be even more damaging than the lack of water to begin with. Instead, water thoroughly and slowly, taking breaks to let the water slowly saturate through the soil to get to the roots. Use room temperature water, as cold water might be too much of a shock. In the future, shorten the time between waterings. A good rule of thumb is to check the soil around each plant daily. If it’s dry to at least two inches down, it’s time to water. If a container plant is repeatedly drying out very quickly, repotting into a slower-draining container might be a good idea, too.

Lighting

Full sun

Spinach thrives best when granted ample exposure to sunlight, fostering sturdy, prolific growth. Its capacity to withstand a level of shadow, however, displays resilience. Excess or inadequate illumination can hamper health, with ideal balance inherent in its original sun-drenched habitat. Each phase of growth warrants proportionate light exposure.

Best Sunlight Practices

Temperature

0 - 43 ℃

Spinach is naturally adapted to moderate climates. Optimally, it thrives at temperatures of 68 to 100 °F (20 to 38 ℃). To regulate temperature in changing seasons, adjust planting locations or use protective coverings when necessary.

Temp for Healthy Growth

Transplant

6-12 inches

To enjoy a lush spinach garden, transplant during the bountiful period of late spring to mid-autumn. Prioritize a sunny spot with well-draining soil and enrich with organic matter for a thriving spinach. Remember, a little nurturing goes a long way!

Transplant Techniques

Pollination

Normal

The pollination habits of spinach rely primarily on the wind's whims, functioning as an elegant dance in the breeze to scatter its fine, lightweight pollen. Spinach's lack of flashy attractants indicates a sole reliance on wind for pollination, not bees or other insects. This mechanism is typically timed for periods when wind velocities are at their peak, making spinach a master at taking advantage of nature's rhythms.

Pollination Techniques

Pruning

Spring, Summer, Autumn

A leafy green renowned for its nutritional value, spinach thrives with regular trimming to encourage healthy growth. Prune outer leaves at the base and thin seedlings to 3-4 inches apart, fostering air circulation and larger leaves. Best done early spring through late fall, coinciding with spinach's active growth. Benefits of pruning include higher yields and prolonged harvest, especially when older leaves are removed to focus energy on new growth.

Pruning techniques

Propagation

Spring

Spinach is typically propagated through seeds with relative ease. The prime season for sowing is Spring, ensuring a higher success rate. Signs of successful propagation include germination and sprout emergence. Pre-soaking seeds can enhance germination rates.

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

Spinach thrives in full sunlight and is commonly cultivated outdoors. When grown indoors with limited light, it may exhibit subtle symptoms of light deficiency that can easily go unnoticed.

(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 spinach 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

Spinach 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 ensure optimal growth, gradually move plants to a sunnier location each week, until they receive at least 6 hours of direct sunlight daily. Use a south-facing window and keep curtains open during the day for maximum sunlight exposure and nutrient accumulation.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

Spinach thrives in full sun exposure and can tolerate intense sunlight. With their remarkable resilience, symptoms of sunburn may not be easily visible, as they rarely suffer from it.

(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.

Just like people, each plant has its own preferences. Learn about your plants' temperature needs and create a comforting environment for them to flourish. As you care for your plants, your bond with them will deepen. Trust your intuition as you learn about their temperature needs, celebrating the journey you share. Lovingly monitor the temperature around your plants and adjust their environment as needed. A thermometer can be your ally in this heartfelt endeavor. Be patient and gentle with yourself as you explore your plants' temperature needs. Cherish your successes, learn from challenges, and nurture your garden with love, creating a haven that reflects the warmth of your care.

Essentials

Regional wintering strategies

Spinach prefers relatively warm temperatures, so maintaining temperatures above {Suitable_growth_temperature_min} during winter cultivation is beneficial for plant growth. The minimum temperature should be kept above freezing point to prevent the plant from freezing damage. When the outdoor temperature approaches -5°C (25°F) during winter, it is advisable to bring Spinach indoors or provide protection by setting up a temporary greenhouse or using materials such as plastic film or fabric to wrap the plant.

Important Symptoms

Symptoms of Low Temperature in Spinach

Spinach has moderate tolerance to low temperatures and thrives best when the temperature is between {Suitable_growth_temperature_min} and {Suitable_growth_temperature_max}. During winter, it should be kept above {Tolerable_growing_temperature_min}. When the temperature falls below {Limit_growth_temperature}, the leaves may darken in color. In severe cases, water-soaked necrosis, wilting, and drooping may occur, and the color of the leaves gradually turns brown.

Solutions

Trim away the frost-damaged parts. Immediately move indoors to a warm environment or set up a makeshift greenhouse for cold protection. When placing the plant indoors, choose a location near a south-facing window to ensure ample sunlight. If there is insufficient light, you can use supplemental lighting.

Symptoms of High Temperature in Spinach

During summer, Spinach should be kept below {Suitable_growth_temperature_max}. When the temperature exceeds {Tolerable_growing_temperature_max}, the plant's growth slows down, the color of its leaves becomes lighter, and it 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 afternoon sun. Water the plant in the morning and evening to keep the soil moist.
