Why Is My Cilantro Flowering?
It is common for cilantro to flower. Usually, this process is known as “bolting", which typically occurs when the plant experiences stress from rising temperatures or other environmental factors. When cilantro bolts, it rapidly flowers and produces seeds, which is a natural survival mechanism. In this part, we'll take a closer look at why your cilantro is flowering.
What Does Cilantro Bolting Look Like?
- Age: Cilantro is an annual plant, and it typically flowers after it has matured, usually within 3 to 4 months after planting.
- Temperature: Cilantro prefers cooler temperatures. If the weather becomes too warm, the plant may bolt (go to seed) prematurely, leading to flowering.
- Watering: Inconsistent watering can stress the plant, causing it to flower. Ensure you are providing adequate moisture.
- Natural Pest Control: Cilantro flowering belongs to a natural pest control measure. When Cilantro flowers, it attracts beneficial insects, such as ladybugs, lacewings, and parasitic wasps, which can prey on common garden pests like aphids and thrips. These delicate blooms provide a source of nectar and pollen, creating a habitat that encourages these helpful insects to thrive in the garden. By promoting a balanced ecosystem, cilantro flowers enhance biodiversity and help reduce the need for chemical pesticides, making them an excellent choice for organic gardening practices.
- Nutrient Levels: Too much nitrogen can encourage leafy growth at the expense of flowers, while too little may prompt the plant to flower as a survival mechanism.
- Crowding: If cilantro plants are too close together, they may compete for resources, leading to cilantro bolting and flowering.
Cilantro Flowering Stages
The flowering stage of cilantro, also known as bolting, occurs when the plant shifts its energy from producing leaves to developing flowers and seeds. This typically happens in response to environmental factors such as temperature and day length, often when the weather becomes warm. The stages of cilantro flowering can be broken down into several key phases:
Cilantro Flowering Stages
- Vegetative Stage: Before flowering, cilantro develops lush green foliage. During this phase, the plant focuses on leaf production, which is the desired harvest for culinary use.
- Initiation of Flowering: As temperatures rise and days become longer, cilantro begins to transition from vegetative growth to flowering. This stage may be triggered by environmental stress, such as high temperatures or insufficient water.
- Bud Formation: Small buds start to form at the tops of the plant. These buds will eventually develop into flowers. At this stage, you may notice a change in the plant's growth pattern as it directs energy towards flowering.
- Flowering Stage: The buds open into small white or pale pink flowers, which usually appear in clusters. This is the peak flowering phase, where the plant is most visually striking and beneficial insects are attracted.
- Seed Development: After flowering, the flowers begin to produce seeds. As the seeds mature, they turn from green to brown, signaling that they are ready for harvest. This stage is crucial for those looking to collect coriander seeds for culinary use or future planting.
- Harvesting Seeds: Once the seeds are brown and dry, they can be harvested. This marks the end of the flowering cycle, and the plant may be cut back or allowed to die off after seed collection.
What to Do When Cilantro Flowers?
When cilantro begins to flower, it indicates that the plant is bolting. This is a natural response to rising temperatures, typically occurring in late spring and summer. When your cilantro is bolting, your plant may quickly produce flower stalks and seeds to ensure reproduction. The flowers are delicate white blooms that eventually develop into coriander seeds. While cilantro bolting is a natural part of the plant's life cycle, it often declines the leaf flavor and quality. While this process is inevitable, there are several strategies you can employ to manage your cilantro plants during this phase.
What to Do When Cilantro Flowers?
Trim Cilantro Flowers
Many gardeners have asked: do I need to trim cilantro flowers? The answer is YES! It’s beneficial to trim cilantro flowers particularly when you want to prolong the life of the leaves and prevent the plant from going to seed too quickly. As mentioned above, when cilantro plant starts to flower, it signals that the plant is bolting, often leading to a decline in leaf quality and flavor. Regularly trimming the flowers and any developing seed heads can encourage the plant to focus its energy on producing more leaves, thus extending your harvest period and maintaining the herb's fresh taste for culinary use.
As soon as you notice immature flower stalks, prune them back. This can delay the bolting process and encourage the plant to produce more leaves for a short time longer.
Harvest Seeds
Once the flowers fade, they will develop into seed heads. You can collect these seeds (known as coriander) once they dry out but before they burst open. This allows you to use them in cooking or save them for planting later
Regular Harvesting Cilantro Leaves
Frequently cutting the outer Cilantro leaves can provide fresh cilantro for your kitchen and help prevent the plant from focusing its energy on flowering.
Prune Regularly
To delay cilantro bolting, regularly prune the plant by removing leaves and immature flower stalks. This can help extend the life of your cilantro before cilantro goes to seed.
Adjust Growing Conditions
If you want to delay cilantro bolting:
- Keep It Cool: Water adequately and use mulch to maintain soil moisture and temperature. Cilantro prefers cooler conditions; thus, providing shade during peak sunlight hours can help.
- Plant at Optimal Times: Sow cilantro seeds in early spring or late summer when temperatures are cooler and daylight is shorter, which can help prevent premature bolting.
Succession Planting
Sow new seeds every two weeks during the growing season to ensure a continuous harvest.
How to Prevent Cilantro from Bolting?
To prevent cilantro from flowering, or bolting, you need to provide optimal growing conditions for them. Cilantro thrives in cooler temperatures, ideally between 50°F and 85°F (10°C to 29°C). Planting cilantro in early spring or fall can help avoid the heat of summer, which often triggers flowering. Additionally, ensuring consistent moisture through regular watering without waterlogging the soil can help maintain healthy growth. Providing partial shade during hot days can also reduce stress on the plant, helping to prolong leaf production and delay cilantro bolting. Lastly, selecting slow-bolting cilantro varieties can further enhance your chances of enjoying fresh leaves for a longer period.
How Do You Grow Cilantro Plants?
Known for its fresh, aromatic leaves and distinctive flavor, cilantro, or Coriandrum sativum, is a versatile herb used in a variety of cuisines around the world. Whether you’re looking to enhance your culinary creations or simply enjoy the beauty of this herb in your garden, it’s essential to understand how to grow cilantro plants. Hopefully, you can grow healthy cilantro plants and enjoy a bountiful harvest.
- Light: Cilantro prefers full sun but benefits from some afternoon shade, especially in warmer climates. It typically requires about six hours of direct sunlight daily. If you fail to give enough sunshine in winter, you can put then under LED grow lights.
- Temperature: The ideal temperature range for cilantro is between 50°F and 85°F (10°C to 29°C). It is a cool-season herb that can tolerate light frosts but struggles in high heat, which can lead to bolting.
- Soil: Cilantro thrives in loose, well-drained soil enriched with organic matter. The optimal PH is a slightly acidic pH of around 6.2 to 6.8.
- Moisture: Ensure the soil retains moisture but is not waterlogged, as cilantro can bolt if the soil is too wet.

Will cilantro grow back after cutting?
Yes, cilantro can grow back after cutting. This makes it a versatile herb for continuous harvesting. When you snip the leaves, it’s best to cut them above the base of the plant, leaving some foliage intact to allow for regrowth. Cilantro is a fast-growing herb, and with proper care—such as adequate sunlight, watering, and nutrients — it can produce new leaves relatively quickly. However, keep in mind that if the plant bolts and flowers, the leaves may become bitter and less desirable for culinary use, so regular harvesting before this stage can help maintain the plant's flavor and vitality.
Why is my cilantro growing small leaves?
Cilantro may be producing small leaves due to several factors, including insufficient sunlight, inadequate watering, nutrient deficiency, or crowding. If the plant isn't receiving enough light (ideally 6-8 hours of direct sunlight daily), it can result in stunted growth. Additionally, inconsistent watering can stress the plant, while a lack of essential nutrients in the soil can hinder leaf development. Lastly, if cilantro is overcrowded, it may compete for resources, leading to smaller leaves. Adjusting these conditions can help promote healthier, larger foliage.
Why is my cilantro turning yellow?
Cilantro leaves may turn yellow due to several reasons, including overwatering, nutrient deficiency, or poor drainage. Overwatering can cause root rot, leading to yellowing leaves as the plant struggles for oxygen. A lack of essential nutrients, particularly nitrogen, can also result in yellowing. Additionally, if the plant is exposed to excessive heat or stress, it may exhibit yellow leaves as a response. Ensuring proper watering, good soil drainage, and adequate nutrition can help address this issue.
