To water Richard's yellow-eyed grass, you can use a garden hose with a spray nozzle, a watering can, or just about any other common watering tool. Generally, Richard's yellow-eyed grass is not too picky about how they receive their water, as they can live off of rainwater, tap water, or filtered water. Often, you should try not to water this plant from overhead, as doing so can damage the leaves and flowers and may lead to disease as well. At times, the best method for watering this plant is to set up a drip irrigation system. These systems work well for Richard's yellow-eyed grass as they apply water evenly and directly to the soil. For one Richard's yellow-eyed grass that grows in a container, you can use a similar watering approach while changing the tools you use. To water a container-grown Richard's yellow-eyed grass, use a cup, watering can, or your tap to apply water directly to the soil.

The remedy for underwatering Richard's yellow-eyed grass is somewhat obvious. When you notice that your plant lacks moisture, simply begin watering it on a more regular basis. The issue of overwatering can be a much more dire situation, especially if you fail to notice it early. When your Richard's yellow-eyed grass is overwatered, it may contract diseases that lead to its decline and death. The best way to prevent this outcome is to choose a proper growing location, one that receives plenty of sunlight to help dry the soil and has good enough drainage to allow excess water to drain rather than pooling and causing waterlogged soils. If you overwater your Richard's yellow-eyed grass that lives in a pot, you may need to consider changing it to a new pot. Your previous container may not have contained soil with good drainage or may not have had sufficient drainage holes. As you repot your overwatered Richard's yellow-eyed grass, make sure to add loose soils and to use a pot that drains efficiently.

Richard's yellow-eyed grass needs water regularly throughout the growing season. Beginning in spring, you should plan to water this plant about once per week. As the season presses on and grows warmer, you may need to increase your watering rate to about two to three times per week. Exceeding at this rate can be detrimental to your Richard's yellow-eyed grass. With that said, you should also ensure that the soil in which your Richard's yellow-eyed grass grows remains relatively moist but not wet, regardless of how often you must water to make that the case. Watering Richard's yellow-eyed grass that lives in a pot is a bit different. Generally, you'll need to increase your watering frequency, as the soil in a pot can heat up and dry out a bit faster than ground soil. As such, you should plan to water a container-grown Richard's yellow-eyed grass a few times per week in most cases, versus just once per week for an in-ground plant.

There are a few different ways you can go about determining how much water to give to your Richard's yellow-eyed grass. Some gardeners choose to pick their water volume based on feeling the soil for moisture. That method suggests that you should water until you feel that the first six inches of soil have become moist. Alternatively, you can use a set measurement to determine how much to water your Richard's yellow-eyed grass. Typically, you should give your Richard's yellow-eyed grass about two gallons of water per week, depending on how hot it is and how quickly the soil becomes dry. However, following strict guidelines like that can lead to overwatering if your plant requires less than two gallons per week for whatever reason. When growing Richard's yellow-eyed grass in a container, you will need to use a different method to determine how much water to supply. Typically, you should give enough water to moisten all of the layers of soil that have become dry. To test if that is the case, you can simply stick your finger in the soil to feel for moisture. You can also water the soil until you notice a slight trickle of excess water exiting the drainage holes of your pot.

It can be somewhat difficult to avoid overwatering your Richard's yellow-eyed grass. On the one hand, these plants have relatively deep roots that require you to moisten the soil weekly. On the other hand, Richard's yellow-eyed grass are plants that are incredibly susceptible to root rot. Along with root rot, your Richard's yellow-eyed grass may also experience browning as a result of overwatering. Underwatering is far less likely for your Richard's yellow-eyed grass as these plants can survive for a while in the absence of supplemental watering. However, if you go too long without giving this plant water, it will likely begin to wilt. You may also notice dry leaves.

You can expect your Richard's yellow-eyed grass’s water needs to increase as the season moves on. During spring, you should water about once per week. Then, as the summer heat arrives, you will likely need to give a bit more water to your Richard's yellow-eyed grass, at times increasing to about three times per week. This is especially true of Richard's yellow-eyed grass that grow in containers, as the soil in a container is far more likely to dry out faster than ground soil when the weather is warm. In autumn, while your Richard's yellow-eyed grass is still in bloom, it may need a bit less water as the temperature has likely declined, and the sun is no longer as strong as it was in summer.

Richard's yellow-eyed grass will move through several different growth stages throughout the year, some of which may require more water than others. For example, you will probably start your Richard's yellow-eyed grass as a seed. While the seed germinates, you should plant to give more water than your Richard's yellow-eyed grass will need later in life, watering often enough to maintain consistent soil moisture. After a few weeks, your Richard's yellow-eyed grass will grow above the soil and may need slightly less water than at the seedling phase. Then, once this plant is mature, you can begin to use the regular watering frequency of about once per week. As flower development takes place, you may need to give slightly more water to aid the process.

There are several reasons why most Richard's yellow-eyed grass grow outdoors rather than indoors. The first is that these plants typically grow to tall. The second reason is that Richard's yellow-eyed grass needs more daily sunlight than most indoor growing locations can provide. If you are able to provide a suitable indoor growing location, you may find that you need to give your Richard's yellow-eyed grass water a bit more often than you would in an outdoor growing location. Part of the reason for this is that indoor growing locations tend to be a lot drier than outdoor ones due to HVAC units. The other reason for this is that soil in containers can dry out relatively quickly as well compared to soil in the ground.

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 Richard's yellow-eyed grass 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 Richard's yellow-eyed grass 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 Richard's yellow-eyed grass is always exposed to the sun.

When the temperature rises above 90℉(32℃), the Richard's yellow-eyed grass 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 Richard's yellow-eyed grass 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 Richard's yellow-eyed grass is still drooping, this means that the plant is losing water fast, and you need to water them.

The Richard's yellow-eyed grass 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 Richard's yellow-eyed grass 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 Richard's yellow-eyed grass 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 Richard's yellow-eyed grass 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 Richard's yellow-eyed grass 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 Richard's yellow-eyed grass needs 6 to 8 hours of direct light every single day. This is whether they are planted outdoors. If the Richard's yellow-eyed grass 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 Richard's yellow-eyed grass 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 Richard's yellow-eyed grass 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.
