When growing a broccoli plant, it is important to be aware of the different stages of growth. By understanding the different stages, you can provide the best possible care for your plant and ensure that it grows healthy and strong. This guide will take you through the different stages of broccoli plant growth, from seedling to full maturity. By the end, you'll have a better understanding of how to care for your own broccoli plants.

Broccoli Total Growing Time

The time it takes for a broccoli plant to reach full maturity varies depending on the type of broccoli plant. Generally, though, you can expect it to take anywhere from 65 to 85 days. There are several things you can do to speed up the process, including providing adequate water and nutrients, planting in a sunny location, and using a grow light.

Broccoli Germination Time

Broccoli seeds will germinate in as little as three days, but it's best to wait a week or two to make sure all the seeds have germinated. Broccoli transplants and seeds offer gardeners the chance to plant two to three weeks before the last expected spring frost because the broccoli plant grows best in cool weather.

Broccoli Growing Stages


The first stage of broccoli growth is to plant seeds. You can do this indoors or outdoors, depending on your preference. Once the seeds have been planted, they will need to be kept moist in order for them to germinate. A good way to do this is to cover the pot or seedbed with a piece of plastic wrap or a lid.

You can also start broccoli seeds indoors during early spring about 6-8 weeks before the final frost date.

Broccoli is a cool-season crop that should be planted in the early spring or fall. Broccoli plants can be direct-seeded or transplanted. When direct seeding, plant the seeds 1/4 to 1/2 inch deep and space them 2 to 3 inches apart. Broccoli grows best when soil temperatures are between 60 and 70 degrees F.


The germination process begins when the Broccoli seed absorbs water and swells. This creates a small crack in the seed coat, which allows the plant embryo to take in air. The young embryonic broccoli plant then starts to grow, first into a root and then a shoot. The roots grow broccoli down into the soil while the shoot grows upwards towards the light.

As mentioned earlier, broccoli seeds will germinate in as little as three days. However, it's best to wait a week or two to make sure all the seeds have germinated. Once they have, you can remove the plastic wrap or lid and allow them to receive direct sunlight.

Broccoli seedlings Stage

A seedling is a young plant that has just germinated from a seed. Once the broccoli seeds have germinated, they will enter the seedling stage. This is when the young plants start to grow their first set of true leaves. The first leaves that appear are called cotyledons or seed leaves. These leaves are different from the true leaves that will come later. Cotyledons are typically wider and thinner than true leaves, and they do not have the same shape or color.

Broccoli seedlings indoors stage last for around two weeks. During this time, the plant will be growing broccoli slowly and will be very vulnerable to pests and diseases. It is important to keep the soil moist but not wet, and to avoid over-fertilizing.

Transplanting Stage

The transplanting stage is when a young plant is moved from one location to another. Broccoli plants can be transplanted at any stage, but it is typically done during the seedling stage. This is because the few plants are still small and have not yet developed a strong root system.

Once the plant has a few sets of true leaves, it is ready to be transplanted into a larger pot or into the vegetable garden. Be sure to plant broccoli by first slowly acclimatizing it to outdoor conditions. transplant it into well-draining soil in a sunny location.

Sprouting Stage

Sprouting is the process of growing new leaves and stems. Broccoli plants typically begin to sprout around the four-week mark. During this time, you will see the plant start to grow new leaves and stems. The new leaves will be smaller than the initial cotyledons, but they will be the same color.

The sprouting stage lasts for two to four weeks. During this time, the broccoli plant will start to grow more rapidly and will begin to produce small buds. You can help the plant along by providing plenty of water and fertilizer. At this stage, pest prevention broccoli could be infested by aphids, caterpillars, cutworms, cabbage loopers, or imported cabbage worms.

First True Leaf Forms

The first true leaves forms once the buds have started to grow. These leaves will be larger and more mature than the seed leaves.

Third True Leaf Forms

The broccoli plant's development speed improves as a result of its ability to photosynthesis. The third set of true leaves, which develop from the second set of bud-like structures in young seedlings, are formed as a result of collenchyma growth hormones within the plant's undifferentiated cells. Each new layer of leaves boosts plant photosynthesis, allowing it to grow.

Vegetative Stage

The vegetative stage is the period of growth where the plant increases in size. Broccoli plants typically enter the vegetative stage around six weeks after sprouting. During the vegetative stage, broccoli seedlings will differentiate, elongate, and expand to form a true set of leaves, roots, and stems.

The vegetative stage lasts for around four to six weeks. This is the stage when the broccoli plant begins to actively grow. During this time, it will produce its first set of yellow flowers, known as the primary or main head. Broccoli plants typically have a period of rapid growth during this stage, so be sure to provide adequate water and nutrients.

Flowering Stage

The flowering stage is the period of time when the broccoli plant produces flower heads. Broccoli plants typically enter the flowering stage around eight to twelve weeks after sprouting.

When broccoli flowers, it lasts for around two weeks. During this time, the broccoli plant will produce its secondary heads. These heads will be smaller than the primary head, but they will be just as edible. At this stage, feeding is required with low nitrogen fertilizer. Avoid feeding your broccoli with fertilizer that contains a high amount of nitrogen. Nitrogen can make your broccoli not produce heads.

The broccoli plant will continue to produce new heads throughout the flowering stage. Be sure to harvest broccoli heads regularly to encourage the plant to produce more.

Side Shoots Stage

Side shoots are the small, secondary heads that grow on the sides of the main stem. Broccoli plants typically produce side shoots around four to six weeks after flowering

The side shoots stage lasts for around four weeks. During this time, the broccoli plant will produce an abundance of side shoots. These shoots can be harvested and eaten just like the primary and secondary heads

The side shoots stage is a great time to start harvesting broccoli. Be sure to check the plants regularly and harvest broccoli heads as soon as they are big enough to eat.

Harvesting Stage

The harvesting stage is the final stage of the broccoli plant's life cycle. Broccoli plants typically reach the harvesting stage around twelve to sixteen weeks after sprouting. When you start seeds indoors and transplant them, the transplant's growth time to harvest is typically around 55 to 85 days.

The harvesting stage lasts for around four weeks. During this time, the broccoli plant will produce its final heads. It is time to harvest broccoli once the central head is fully developed, but before the individual green buds open and display small yellow flowers.

The harvesting stage is the final stage of the broccoli plant's life cycle. Be sure to harvest broccoli regularly to encourage the plant to produce more. The second crop of broccoli thrives in the fall months and can be started three weeks before the first anticipated fall frost.

Tips to speed up broccoli plant growing stages:

  1. Broccoli plants grow best in full sun, so choose a spot in your vegetable garden that receives plenty of sunlight.
  2. Broccoli prefers well-drained soil, so be sure to amend your soil with compost or other organic matter before planting. Broccoli is a heavy feeder, so be sure to fertilize your plants regularly.
  3. Broccoli is a cool-weather crop, so it is best to plant it in the spring or fall.
  4. Harvest your broccoli when broccoli heads are firm and green. Cut the main stem just below the main head with a sharp knife.
  5. Broccoli can be susceptible to pests and diseases, so be sure to keep an eye out for problems and take steps to control them.
