When watering the Showy colchicum 'Atrorubens', you should aim to use filtered water that is at room temperature. Filtered water is better for this plant, as tap water can contain particles that are harmful to its health. The reason that the water should be at room temperature or slightly warmer is that the Showy colchicum 'Atrorubens' comes from a warm environment, and cold water can be somewhat of a shock to its system. Also, you should avoid overhead watering for this plant, as it can cause foliage complications. Instead, simply apply your filtered room temperature water to the soil until the soil is entirely soaked. Soaking the soil can be very beneficial for this plant as it moistens the roots and helps them continue to spread through the soil and collect the nutrients they need.

Both overwatering and underwatering will be detrimental to the health of your Showy colchicum 'Atrorubens', but overwatering is a far more common issue. When this species receives too much water, its stems and leaves may begin to wilt and turn from green to yellow. Overwatering over a prolonged period may also lead to diseases such as root rot, mold, and mildew, all of which can kill your plant. Underwatering is far less common for the Showy colchicum 'Atrorubens', as this plant has decent drought tolerance. However, underwatering remains a possibility, and when it occurs, you can expect to find that the leaves of your Showy colchicum 'Atrorubens' have become brittle and brown. It is crucial that you notice the signs of overwatering as soon as possible when caring for your Showy colchicum 'Atrorubens'. Some of the diseases that arise from overwatering, such as root rot, may not be correctable if you wait too long. If you see early signs of overwatering, you should reduce your watering schedule immediately. You may also want to assess the quality of soil in which your Showy colchicum 'Atrorubens' grows. If you find that the soil drains very poorly, you should replace it immediately with a loose, well-draining potting mix. On the other hand, if you find signs that your Showy colchicum 'Atrorubens' is receiving too little water, all you need to do is water more regularly until those signs have subsided.

If your plant is in a pot. The most precise way to decide whether your Showy colchicum 'Atrorubens' needs water is to plunge your finger into the soil. If you notice that the first two to three inches of soil have become dry, it is time to add some water. If you grow your Showy colchicum 'Atrorubens' outdoors in the ground, you can use a similar method to test the soil. Again, when you find that the first few inches of soil have dried out, it is time to add water. During the spring and early fall, this method will often lead you to water this plant about once every week. When extremely hot weather arrives, you may need to increase your watering frequency to about twice or more per week. With that said, mature, well-established the Showy colchicum 'Atrorubens' can show an admirable ability to withstand drought.

When it comes time to water your Showy colchicum 'Atrorubens', you should not be shy about how much water you give. With the first two to three inches of soil dry, this plant will appreciate a long and thorough watering. Supply enough water to soak the soil entirely. The amount of water you add should be enough to cause excess water to flow through the drainage holes at the bottom of your pot. If you don’t see excess water draining from the pot, you have likely underwatered your plant. But do not let the water accumulate inside the soil, which will be very dangerous to the plant as well. Alternatively, a lack of water draining through the pot could indicate poorly draining soils, which is detrimental to the health of this plant and should be avoided. If the plant is outside, 1 inch of rain per week will be sufficient.

The water needs of the Showy colchicum 'Atrorubens' can change depending on growth stages as well. For example, when your Showy colchicum 'Atrorubens' is in the first few years of its life, or if you have just transplanted it to a new growing location, you will need to give more water than usual. During both of those stages, your Showy colchicum 'Atrorubens' will put a lot of energy towards sprouting new roots that will then support future growth. For those roots to perform their best, they need a bit more moisture than they would at a more mature phase. After a few seasons, your Showy colchicum 'Atrorubens' will need much less water. Another growth stage in which this plant may need more water is during the bloom period. Flower development can make use of a significant amount of moisture, which is why you might need to give your Showy colchicum 'Atrorubens' more water at this time.

The Showy colchicum 'Atrorubens' will have its highest water needs during the hottest months of the year. During the height of summer, you may need to give this plant water more than once per week, depending on how fast the soil dries out. The opposite is true during the winter. In winter, your plant will enter a dormant phase, in which it will need far less water than usual. In fact, you may not need to water this plant at all during the winter months. However, if you do water during winter, you should not do so more than about once per month. Watering too much at this time will make it more likely that your Showy colchicum 'Atrorubens' will contract a disease.

It is most common to grow the Showy colchicum 'Atrorubens' indoors for any gardener that does not live in temperate and tropical regions. Those gardeners should consider the fact that soil in a container can dry out a bit faster than ground soil. Also, the presence of drying elements such as air conditioning units can cause your Showy colchicum 'Atrorubens' to need water on a more frequent basis as well. if you planted it outside. When that is the case, it’s likely you won’t need to water your Showy colchicum 'Atrorubens' very much at all. If you receive rainfall on a regular basis, that may be enough to keep your plant alive. Alternatively, those who grow this plant inside will need to water it more often, as allowing rainwater to soak the soil will not be an option.

Pruning your Showy colchicum 'Atrorubens' 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 Showy colchicum 'Atrorubens' 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 Showy colchicum 'Atrorubens' is growing.

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 Showy colchicum 'Atrorubens' 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 Showy colchicum 'Atrorubens' 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.

Early spring and late winter are the best times to prune your Showy colchicum 'Atrorubens' on a large scale. If you want to control the size of your Showy colchicum 'Atrorubens', 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 Showy colchicum 'Atrorubens' is growing vigorously and these types of leaves need to be pruned back immediately. These parts of the Showy colchicum 'Atrorubens' cannot be restored and pruning increases the ventilation of the plant and facilitates its 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 Showy colchicum 'Atrorubens' depends on where you live and how established your plant is. For example, if your Showy colchicum 'Atrorubens' 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 Showy colchicum 'Atrorubens' is pruned too late in the season, it can leave new growth at risk for damage or disease. However, if your Showy colchicum 'Atrorubens' 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 Showy colchicum 'Atrorubens' 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 Showy colchicum 'Atrorubens' is growing.

Showy colchicum 'Atrorubens' needs full sun every day, and these plants rely on a minimum of six hours of sunlight to keep their leaves, roots, and blooms in a healthy state. Even though most perennials need six hours of sunlight a day, plants like the Orange Daylily or Giant Coreopsis could live off less sun for a minimum of three hours daily. Even though these perennial flowering plants can live with only three hours of direct sunlight, they won't be able to thrive like they would in sunnier conditions.

The few Perennial Flowering Plants that don't like excessive heat in warm climates might react poorly to too much sun if they have heat damage. These plants may wilt or dry out from too much sun and may also develop growth issues if they're regularly in the sun during the most intense heat of the day. Some plants don't need protection from the light afternoon sun, but those that are harmed by intense afternoon exposure should be provided some shade in warmer climates. Gardeners could give these plants plenty of shade by planting them in spots that don't receive direct heat during the afternoon, like under trees or behind bushes.

While many perennial plants need plenty of sun to bloom to their fullest extent, some of them benefit from less sun in warmer climates. For example, people who live in hotter climates might want to provide shade for their flowering perennials in the hot afternoon sun, and this is even more true for months in the summer. Even though some perennial flowering plants will benefit from partially shaded in the hottest climates, plants like the Giant Coreopsis aren't intimidated by too much sun. They might sit outside in the full sun in hot weather and still thrive.

If you're growing Showy colchicum 'Atrorubens' and you aren't getting enough sunlight, you'll notice signs of inadequate requirements in your plants. Most plants won't produce as many blooms as they would if they had full sun exposure. Some plants will develop dry spots on their leaves, but most of these plants will still bloom in the inadequate sun. Even though they bloom, the flowers will be smaller and less full.

Showy colchicum 'Atrorubens' is great flowers in gardens and will have optimum blooming if it gets six hours of sunlight a day minimum. Sometimes, flowers stay fresh longer if they're partially shaded during the really hot parts of the day. When Showy colchicum 'Atrorubens' is young, gardeners want to ensure their younger plants are getting plenty of sunlight but don't have to endure intense heat during the afternoon sunlight. If you have a fully mature plant, provide it with plenty of sun so it may keep up its growth properly.

Showy colchicum 'Atrorubens' will need a minimum of six hours of light to best support their photosynthesis cycles. These flowering plants need the sun to help their foliage and blooms grow. However, certain perennial flowering plants like the Giant Coreopsis might need anywhere from eight to twelve hours of full sun a day to maintain their large flowers and healthy foliage.

If you want your Showy colchicum 'Atrorubens' to grow healthy and bloom as much as possible during its blooming season, you should try to give your plant six hours of direct sunlight. Some perennial plants might even do more sunlight and could sit in the sun for up to twelve hours, depending on the heat in the area and the general environment. Plants like the Red Hot Poker and Giant Coreopsis thrive in much hotter climates and might sit in all types of strong sunlight. Some home gardeners have to use grow lights because their spaces don't allow for tons of outdoor sunlight. Most perennials could grow happily in grow lights, but they will need anywhere from eight to fourteen hours of artificial light to stay strong since these lights don't have as much power as the sun.

The leaves of the Showy colchicum 'Atrorubens' comprise most of its main structure, and fertilization is one of the most impactful ways that you can ensure that those leaves look great while also serving their function. Proper fertilization will help your Showy colchicum 'Atrorubens' hold leaves with consistent color and a healthy texture. Fertilization also works below the soil's surface to help your Showy colchicum 'Atrorubens' generate new roots and maintain the roots that are already part of the root system. This means that fertilization will not just keep your plant healthy now, but it will also help your plant be better capable of absorbing soil nutrients in the future.

If you grow your Showy colchicum 'Atrorubens' outdoors each year, this perennial plant will send new growth shooting out in early spring. The emergence of those leaves is a sign that the time is right to begin fertilization for the year. Often, a Showy colchicum 'Atrorubens' will perform just fine with a single application of fertilizer when the spring arrives. However, if you wish to maximize the growth of your Showy colchicum 'Atrorubens', you can repeat the feeding multiple times throughout the spring and early summer. If you choose this route, you can feed your Showy colchicum 'Atrorubens' about once every month to a month and a half.

In the late fall and winter, your Showy colchicum 'Atrorubens' will enter a dormant phase in which it will no longer produce new growth. At this time, you should avoid fertilizing your Showy colchicum 'Atrorubens'. If you choose to fertilize multiple times during spring and summer, you should begin reducing your fertilization rate as summer approaches, as your Showy colchicum 'Atrorubens' 's growth rate will also slow. Overall, it is never a wise choice to fertilize your Showy colchicum 'Atrorubens' during times when the weather is unseasonably hot or when the soil is extraordinarily dry. Fertilizing in either of those cases can stress your Showy colchicum 'Atrorubens' and cause it to perish prematurely.

Fortunately, choosing the best fertilizer for a Showy colchicum 'Atrorubens' is a very straightforward task. These plants will thrive on a general-purpose garden fertilizer that has equal amounts of nitrogen, phosphorus, and potassium. A fertilizer that has a ratio of 10-10-10 or something similar will be very effective. When in doubt, be sure to avoid fertilizers that have high amounts of nitrogen. Most of the best fertilizer for a Showy colchicum 'Atrorubens' will come in a granular form. These fertilizers should be slow-release and will be very easy to apply to the soil. It can also be helpful to feed your Showy colchicum 'Atrorubens' using an organic soil amendment such as compost.

Wait until your Showy colchicum 'Atrorubens' has just barely poked its first leaves through the soil's surface in early spring. Once you see that sign, apply a granular slow-release fertilizer with a balanced formula to the soil that surrounds the base of your Showy colchicum 'Atrorubens'. You can repeat a similar process later in the season if you choose. When reapplying fertilizer to a Showy colchicum 'Atrorubens', you should, again, apply the fertilizer to the soil at the base of the plant rather than to the plant itself. At times, this may require you to move some leaves out of the way to access the soil above the roots. It's also often a good choice to water your Showy colchicum 'Atrorubens' before and after you feed it.

The Showy colchicum 'Atrorubens' doesn't necessarily need to receive high volumes of fertilizer each year, which means overfertilization is entirely possible. If you overfertilize your Showy colchicum 'Atrorubens', you will likely notice first that the leaves have turned brown. Overfertilization of Showy colchicum 'Atrorubens' is especially common if you use a fertilizer that has higher concentrations of nitrogen. High nitrogen content will likely cause the leaves of your Showy colchicum 'Atrorubens' to become discolored, lose much of their moisture, and begin curling at the margins. Many gardeners avoid such complications by limiting fertilization of their Showy colchicum 'Atrorubens' to once per year in early spring.
