Gilia tricolor (bird's-eyes, bird's-eye gilia, tricolor gilia) is an annual flowering plant in the phlox family (Polemoniaceae).
Bird's-eye Gilia is fairly disease-resistant and generally does not tend to get sick. Nevertheless, it can be affected by pests and diseases present in its environment. These issues are typically mild. For care, the plant requires a moderate level of maintenance. It should be pruned regularly to keep a tidy appearance and support healthy growth. Fertilizing can also help encourage flowering. Bird's-eye Gilia is appropriate for anyone with an outdoor area, such as a garden or patio, and does not demand extensive care experience. It may need more attention when grown indoors.
How to keep Gilia Tricolor.
Light
Bird's-eye Gilia grows best when it gets a plentiful amount of sunlight each day. In its native habitat it is used to open areas with abundant light. Importantly, too little sun can cause stunted growth or reduced vigor. Although it usually tolerates heavy exposure, too much sun can cause wilting or damage to the leaves.
Water
Bird's-eye Gilia thrives in conditions that mimic its natural habitat, tolerating drought but preferring moderate moisture. To maintain its health, water the plant weekly and ensure it is in well-draining soil to avoid overwatering and waterlogging. This plant is also suitable for indoor growth, but it's important to regularly check the soil moisture.
Temperature
Bird's-eye Gilia comes from temperate regions and tolerates temperatures ranging from 68 to 95 °F (20 to 35 ℃). It generally favors the upper end of that range. As seasons shift, the plant may need adjustment to temperatures within this limit, especially during extreme winter.
Fertilizer
Once most of Bird's-eye Gilia's flowers have opened to full size, resume fertilizing. When blooms reach their peak production, start feeding again every three to four weeks, weather permitting. Then, when the plant begins to produce fewer new flowers, discontinue fertilizing; there's no point in feeding it if it can no longer set more blooms.
Pruning
Bird's-eye Gilia showcases vibrant tricolored blooms and should be pruned between early and late spring. Start by removing dead stems to improve air circulation. After the initial bloom, lightly trim the plant to encourage a second flowering. Once the blooms have faded, cut the plant back to the base. To prevent infection, always use clean, sharp tools for pruning.

How should I water my Bird's-eye Gilia plant?
There are several ways to water Bird's-eye Gilia. You can use a garden hose with a spray nozzle, a watering can, or any other common watering tool. This plant is not too particular about the type of water it receives, so rainwater, tap water, or filtered water will suffice. It's best to avoid watering from above as this can harm the leaves and flowers and potentially cause disease. A drip irrigation system is often the most efficient method for watering Bird's-eye Gilia, as it delivers water evenly and directly to the soil. If you have a container-grown Bird's-eye Gilia, you can use a cup, watering can, or tap to water it directly onto the soil.
Why should I use fertilizer on my Bird's-eye Gilia?
Plants, including Bird's-eye Gilia, require nutrients to survive. This is a well-known fact among gardeners, regardless of their level of experience. Without proper nourishment, Bird's-eye Gilia will quickly die out after its first pollination. To ensure its continued growth and the production of large, beautiful flowers throughout the blooming season, it is crucial to provide the appropriate nutrients in the right quantities. Fertilizer plays a vital role in helping Bird's-eye Gilia develop a robust, healthy root system. This is particularly important as the plant has a delicate and easily damaged root structure. By fertilizing the plant during planting, a strong foundation and stability can be established, allowing for an impressive display of flowers. Moreover, when fertilization is timed correctly, it can significantly lengthen the flowering period of Bird's-eye Gilia.
What are the sunlight requirements for Bird's-eye Gilia?
Bird's-eye Gilia requires above 6 hours of direct sunlight daily to thrive best. It is naturally adapted to open settings with extensive light exposure. Insufficient sunlight can lead to stunted growth or diminished vitality, whereas too much direct sunlight, although generally tolerated, might cause wilting or foliage damage. To ensure plant happiness, it's crucial to observe the movement of sunlight through your garden and select spots that provide a balanced mix of light and shade.
What is the native environment of Bird's-eye Gilia?
Bird's-eye Gilia is native to temperate environments and is well-adapted to temperatures ranging from 68 to 95 °F (20 to 35 °C), showing a preference for the higher end of this temperature spectrum. As seasons change, particularly with the onset of extreme winter conditions, care may need to be adjusted to ensure the plant remains within its comfortable temperature range. Remarkably, Bird's-eye Gilia is highly cold-tolerant, requiring no extra measures for frost protection during winter. To prepare for winter, it is advised to water the plant generously before the first freeze of autumn to keep the soil moist, aiding in preventing drought and water scarcity during the colder months and into early spring.
What should I do if I give my Bird's-eye Gilia too much water or not enough water?
To prevent underwatering Bird's-eye Gilia, the solution is simple: water the plant more frequently when you notice it lacking moisture. However, overwatering can be a more serious issue if not caught early. Overwatered plants are prone to diseases that can lead to decline and death. To avoid this, select a suitable location for your Bird's-eye Gilia with ample sunlight to aid in drying the soil and good drainage to prevent water from pooling. If your potted plant is overwatered, consider transferring it to a new pot with proper drainage and loose soil during repotting.
When should I put fertilizer on my Bird's-eye Gilia?
Bird's-eye Gilia experiences rapid growth early in the growing season, after the risk of the last frost has passed. This is the best time to fertilize Bird's-eye Gilia, specifically during planting when it is first placed in the ground or in planters. This initial dose of fertilizer will be sufficient until later in the year when the blooms are at their peak. Once the season is in full swing and most of Bird's-eye Gilia's blooms have fully developed, it is time to start fertilizing again. This should be done every three to four weeks, as long as the weather allows. However, once Bird's-eye Gilia starts to produce fewer new blooms, it is no longer necessary to fertilize as it cannot produce any more blooms.
How can artificial lighting compensate for insufficient natural sunlight for Bird's-eye Gilia?
Indoor Bird's-eye Gilia plants benefit significantly from adequate artificial lighting, especially when natural sunlight is insufficient. LED lights are a popular choice, capable of providing specific wavelengths of light needed for optimal growth. For full sun plants, 30-50W/sq ft of artificial light is recommended; partial sun plants need 20-30W/sq ft, while full shade plants should get 10-20W/sq ft. Position the light source 12-36 inches above the plant to mimic natural sunlight, and ensure the plant receives 8-12 hours of light per day.
How does Bird's-eye Gilia handle low temperatures?
Bird's-eye Gilia exhibits remarkable tolerance to low temperatures, maintaining its resilience down to -25°C. While it may not show noticeable effects during the winter, temperatures below this threshold can lead to a reduction or even absence of sprouting come spring. To mitigate these effects, it's recommended to remove any parts of the plant that fail to sprout as the weather warms.
How often do I need to water my Bird's-eye Gilia?
Bird's-eye Gilia requires regular watering throughout the growing season. Starting in spring, watering once per week is recommended. As the season progresses and temperatures rise, it may be necessary to water two to three times per week. However, exceeding this watering rate can harm the plant. Regardless of frequency, the soil should be moist but not wet. Watering Bird's-eye Gilia in a pot is slightly different. Container-grown plants typically need more frequent watering as the soil in pots can heat up and dry out faster than ground soil. In most cases, plan to water a potted Bird's-eye Gilia a few times per week, compared to once per week for an in-ground plant.
When is it not a good time to fertilize my Bird's-eye Gilia?
Regular fertilizing is important for Bird's-eye Gilia, but it can be applied at the wrong time. In certain situations, it's necessary to hold back the fertilizer. These situations are often related to climate, but they can also involve other controllable factors. If there is something wrong with the plant, soil, or climate, it's best to wait until the issues have been resolved and the plant has recovered. For example, it's not advisable to fertilize when there are severe or unexpected changes in the weather. If a cold snap occurs in the middle of summer, it's better to wait until it warms up again before starting to fertilize. Similarly, if the soil becomes too dry or compacted, it won't be able to absorb the fertilizer properly. In such cases, the fertilizer will go straight to the roots without being spread through the soil, which isn't ideal for Bird's-eye Gilia. Another time to avoid fertilizing is when temperatures are extremely high, such as during the hottest parts of the day when it reaches 90 degrees Fahrenheit. Fertilizer can break down at different rates depending on temperature, so it's important not to let hot temperatures break down the fertilizer too quickly. Additionally, it's important to address any pests or diseases before applying fertilizer again.
What are the symptoms of inadequate light exposure in Bird's-eye Gilia?
Symptoms of inadequate light in Bird's-eye Gilia include smaller new leaves, leggy or sparse growth, faster leaf drop, slower or halted new growth, and lighter-colored or chlorotic leaves. Additionally, overexposure to sunlight can cause sunscald, leaf curling, wilting, leaf scorching, and chlorosis, indicating damage from intense light or imbalanced light conditions.
What should I do if Bird's-eye Gilia is exposed to high temperatures?
Exposure to temperatures above 35°C can halt the growth of Bird's-eye Gilia and increase its susceptibility to rot. In such cases, trim away any sunburned or dried-up parts of the plant. Moving the plant to a shaded area during the peak midday and afternoon sun, or utilizing shade cloth, can help protect it. Additionally, watering the plant during the cooler morning and evening hours helps maintain soil moisture and supports its health under high temperature stress.
