Without proper watering, this beautiful ornamental grass will underperform. In the ground, watering issues can be solved, but In a container, too much or too little water will kill Proso millet in short order. When Proso millet isn't receiving the right amount of water, it may stop growing. In the case of overwatering, it will begin to display yellow leaves with brown tips. Underwatering can produce drooping leaves, weak seed head production, and browned leaves. If you suspect your Proso millet has been improperly watered, the first thing to do is figure out if the problem is too much or too little. If your Proso millet is getting too much water, stop watering it immediately. Sometimes it can take weeks for heavy soils to dry out, so be patient. At the first sign of new growth, test the soil for moisture and decide whether it needs more water or not. The solution for Proso millet receiving too little water is even simpler: give the grasses a nice, deep drink and see if it perks up. Bearing all of this in mind, remember that a long, deep watering is always better than a lot of shallow, frequent waterings. The reason for this is that deep watering encourages grasses to grow deep roots, which makes them more drought resistant and less prone to problems from watering.

The watering needs of Proso millet will vary depending on where it is planted. Generally, you should water this grass every week. In hot climates, once or twice a week watering in the summer may be necessary. In moderate climates, watering once every seven days or more may be enough. Grass in containers almost always need more frequent watering than grasses in the ground. But with a species such as this that can thrive in full sun or part shade, the location also matters. Shaded grasses need to be watered less frequently than in-ground grasses. Proso millet should only be watered when the soil is dry. If you’re unsure when to water, there are a few key signs you can use as your cue. Pressing your finger a couple of inches into the soil will tell you if the soil is dry. For a potted grass, you can weigh the grass with a portable scale to see how light it is, but you can also quickly feel when the pot is light from lack of water. Like many types of grass, the blades may appear folded along their centers and thinner than usual when the roots lack sufficient water. Despite its drought tolerance, regular, deep waterings will reward you with a beautiful color. In the wild, Proso millet grows in open scrubland, where it would be subject to extreme heat, loads of bright sun, and intermittent rain. Because this grass is drought resistant, you might expect never to need to water it. But don’t let its hardiness fool you, Proso millet still needs care and attention. Even though this hardy grass can handle harsh, dry conditions, gardeners agree that it thrives best with consistent water. When first planted, Proso millet will need more frequent water until it has established deep roots. For Proso millet in pots, the soil will dry out quickly, especially if the pot is in hot, direct sun for a large part of the day. Test the soil every 3 to 4 days and water only when it feels dry. Proso milleted in the ground generally needs less watering, but that depends on the soil it is grown in. Heavy clay soil holds water for a long time and may feel dry at the surface while still retaining plenty of moisture below the ground. Sandy soils that drain quickly will need to be watered more often.

You can often tell if you are watering enough by the rate of growth of your grasses. Proso millet during the hottest months of the year and has been known to double in size in a year’s time. If the weather is hot and the grass is not growing vigorously, you may need to adjust your watering schedule. In winter, you might be able to get away with watering only once a month, but you will still want to touch the soil to test for moisture. During a growth cycle (in the warmest months), the grass will need more water than usual. But during winter and cooler months, the need for water will be dramatically reduced. The most important thing to remember about Proso millet is that the soil it is planted in should always be allowed to dry out completely before adding water.

You must expose the plants to at least 6 to 8 hours of sunlight daily. They prefer more exposure to the morning light, especially in the summer. The Proso millet needs full sun and more sunlight that it can get. The more light these species get, the more they can manufacture food, produce beautiful blooms, and survive.

The Proso millet grows best under full sunlight. It's best not to crowd them together so they can get exposure to the sun evenly. The leaves shouldn't be starved with sunlight. If planted in pots, try to expose the herbaceous flowers in windows with direct sun and ensure they receive full sunlight regardless of the months. They don't tend to do well in partial or filtered light as this will not produce strong stems and healthy flowers. It's best if the Proso millet is always exposed to the sun.

When the temperature rises above 90℉(32℃), the Proso millet can get damaged by extreme temperatures, especially if they are exposed to many hours of sun. It's always ideal for providing some shade from the light in the afternoon in the summer. It's always important to keep in mind that the sunlight in the summer is stronger than the one in the winter. Sunlight exposure is also 50% longer in the summer than in the winter. If the Proso millet is too stressed with sunlight, you might want to keep them fully hydrated. Water them when the top of the soil is about 2 inches dry, and move the plants indoors if it's too hot outside. This is the case if they are planted in containers. It can be normal for the plant leaves to wilt during the day. Generally, they can recover at night. However, when you notice that the Proso millet is still drooping, this means that the plant is losing water fast, and you need to water them.

The Proso millet does not need any protection from the sun. In fact, they love the sun, and some species are heliotropic. Plant them in south-facing gardens whenever possible so they can be exposed from morning to afternoon. While the sun can benefit them, some may experience a sunburn. You might offer protection from the afternoon and midday sun through a shade of a tree or a wall. Growing the Proso millet in shady areas is impossible because the larger flowers would require a lot of energy to grow and produce. Always provide the lighting conditions and set them in an area with full sun for best results.

When the Proso millet does not get adequate sunlight, or they are not placed in full sun locations, it's worth noting that the photosynthetic process will slow down. A lack of sunlight will cause the stems to become more leggy since they become thin and long since they tend to seek too much sunlight. They will not bloom and produce seeds in the shade. Inadequate sunlight will also mean that the older leaves can die, the color of the new ones is lighter than the old foliage, and the new growth is smaller than the last ones. The Proso millet indeed loves the sun so much. However, they can wilt when exposed to excessive heat and ultraviolet light during the extreme summer months, so be careful. You might want to cover them with a net that has a green shade, especially in the summer, to prevent the leaves and the flowers from scorching. When they are indoors, reduce the heat with the help of a fan.

When the Proso millet is growing, they need more light than their mature counterparts. The younger ones should receive adequate light, but they might not be prepared for sudden full sunlight, especially if they are grown in a nursery. They can be more sensitive to the summer sun, so the lighting should be gradual and slow.

During summer or late spring, the Proso millet needs 6 to 8 hours of direct light every single day. This is whether they are planted outdoors. If the Proso millet is planted in pots or you're growing them in the winter, they need direct fluorescent lights that help them grow better. Make sure to place them in an indoor area where they are facing south or east so they can have enough sunlight for photosynthesis.

When transplanting the plants, they should not be exposed to sudden sunlight. Give the Proso millet to grow and mature before transplanting outside. Some species of herbaceous plants can grow taller and might cast a shade on other young plants. Allow between 80 to 100 days of growing season before planting another batch to ensure that every plant receives more than enough sunlight for at least 6 hours a day. Make sure that the Proso millet receives the best light possible, especially if it's planted in a nursery. These are sun-loving plants, but too much sunlight with a very hot temperature is also detrimental to their growth. Indoor lights should be replaced with natural sunlight as much as possible since these species crave this every day.

The best temperature for Proso millet depends on the time of year. There are two primary seasons to discuss for temperature: the growing season, and the dormancy season. During the growing season, once Proso millet has begun to sprout, the ideal temperature range should be anywhere from 65~80℉(18~27℃). Any colder than 15℉(-10℃), and the plant will suffer; its leaves may brown and wilt, but if this is a short cold snap, then Proso millet may be able to survive with some help. During the warmer parts of the year, Proso millet will need to be similarly protected from temperatures that are too high. 95-105℉ (35-40℃) is the top of this plant’s temperature range, and anything above that will compromise the integrity of the foliage and blooms of Proso millet. Hotter temperatures can cause wilting, drooping, and even sunburn on the leaves, which can be difficult for Proso millet to recover from. There are quite a few ways to combat this issue that are quick and easy!

If this is the first year of your Proso millet outside as a new plant, then it may need a little extra tending during the coldest months of the year. Not only can frost more severely damage a first-year Proso millet, but it can also prevent it from growing back as a healthy plant come spring. This plant needs to be kept at 40℉(5℃) or above when they’re not yet established, which can be done either by bringing your Proso millet inside for a month or two, or putting up mulch or fabric barriers that protect from frost damage. It’s also a good idea to plant Proso millet in a shadier spot during the first year or two, as smaller and weaker plants have a more difficult time maintaining their own temperatures in the heat. First-year Proso millet should receive no more than five hours of direct sunlight per day, particularly if the ambient daytime temperature gets above 80℉(27℃). Shadecloth and frequent watering or misting are the keys to summer heat control.

If cold temperatures (below 15℉(-10℃)) do occur during the growing season, there are a few measures you can take to help protect Proso millet from frost or cold damage. If you’re growing Proso millet in a container, then the container can simply be brought inside in bright, indirect light until the temperatures rise up over the lower threshold again. Another option that’s better suited for ground-planted Proso millet is to use mulch or horticultural fabric to create an insulated barrier around the plant, which will protect the plant from frost and cold wind. For temperatures that are hotter than 80℉(27℃) in the shade during the day, be careful to only expose Proso millet to six hours or less of sunlight per day, preferably in the morning hours. Putting up shade cloth, or a fine plastic mesh, can help reduce the amount of direct sunlight that hits the plant during the hottest parts of the day. You can also install a misting system that allows for a slow release of cooling mist around the base of the plant during the day to lower ground temperatures.

During the cold winter months, Proso millet needs a certain measure of cold in order to stay in dormancy until it’s time to sprout. Sprouting too early, that is before the danger of the last frost has passed, can be fatal to Proso millet, especially if it’s already had a head start when the frost hits. Winter temperatures should ideally stay below 32℉(0℃), but if they get up to 40℉(5℃), everything will be just fine. An unexpected warm spell during the cold months, which can happen in more temperate climates like woodland rainforests, can trigger a premature sprout from Proso millet. In this case, if there’s still imminent danger of frost, you may want to try covering it with clear plastic on stakes so that the cold has less of a chance of damaging the new sprout. This setup can be removed when the danger of frost has passed. Occasionally, Proso millet will be able to resprout at the correct time without any help, but this method increases the chances of a successful second sprouting.

All plants need nutrients to grow, but some types are able to take what they need and don’t need any supplementation with fertilizers. The main reason to fertilize Proso millet is to increase the yield in each harvest. Proso millet, like other plants, use nutrients to support growth and all internal processes that result in edible seeds or grains. Nutrients allow plants to grow and bloom, perform photosynthesis, and ultimately produce seeds or fruits. A lack of nutrients can reduce tillering (the production of extra branches on a single stem), smaller seed size, and low protein content in the finished product.

Generally spring is the best time to fertilize Proso millet is in the spring. Many types of Proso millet do well with a schedule of three major fertilizer treatments during the growing season. The first is before seeds are planted, the second about a month after seedlings emerge, and then a final treatment about 1 to 1.5 months after the second one. Certain types of Proso millet also benefit from a fertilizer boost at the time of planting. Nutrients are necessary for all stages of the growth cycle. Since some types of Proso millet take as little as a month to go from seed to harvest, it is vital for them to have enough nutrients to reach full size as quickly as possible.

Regular feeding is vital for keeping Proso millet healthy and strong, but there is a danger of over-fertilizing or fertilizing during the wrong season. Avoid fertilizing when the soil is very dry or during especially warm or cold weather. Be careful about allowing fertilizers to be in indirect contact with seeds, since it can cause them to fail to germinate. Also be sure to check if your fertilizer is safe to come in direct contact with the plant, or if the plant is likely to be damaged if fertilizer touches the leaves and fruits. Many types of fertilizer are only safe when used in soil near the plants, but should not be applied over the tops of actively growing plants.

Soil tests are important to determine what kind of nutrients are present or absent in the soil. This is particularly relevant for commercial or other large-scale operations where the success or failure of a harvest has significant financial implications. Depending on the soil in your area and the type of Proso millet you are planning to grow, different nutrients may need to be introduced. It is important that the fertilizers provide plenty of phosphorus, as well as smaller amounts of nitrogen and potassium. Secondary nutrients and micronutrients are also necessary to ensure a successful harvest. For example, sulfur, copper, manganese, and zinc are all essential for the development of this plant.

The method of applying fertilizer will depend very much on the scale of the operation, the tools available, and the type of fertilizer being used. In general, fertilizers come in just two different formats: liquid or dry. Liquid fertilizers could be chemical or natural (such as fish fertilizer or compost tea), and dry fertilizers include everything that isn’t liquid, including compost, manure, and powdered or granular fertilizers. There are also some dry fertilizers that are made to be diluted in water before use. After determining what type of fertilizer to use and the format, the next (very important) step is to determine how much to use for your Proso millet. Detailed formulas are available to help you calculate the correct application to get a high yield without over-fertilizing. For larger operations, tractor-attached applicators can be used to scatter dry fertilizer or evenly spray liquid fertilizer. Home gardeners can apply fertilizer by hand or by using readily-available garden tools. Be sure to water thoroughly after watering with any dry fertilizer to be sure that it soaks into the soil.

If the Proso millet gets too much fertilizer at one time, there is a risk that the plant will grow too quickly without the proper root system to support it. Without this, the plant may not be able to take up enough water and nutrients, resulting in a weaker harvest. This can cause plants that are not able to support their own weight and fall over, or that simply fail to thrive. Some farmers have noted that over-fertilization can lead to increased fungal infections in certain types of Proso millet. It is best to avoid over-fertilizing in the first place, as it can be difficult to sufficiently flush extra fertilizer out of the soil and salvage a large number of plants.
