How to Grow Broccoli From Seed
Broccoli, which was first cultivated by Italians about 2,000 years ago, is now included in all balanced diets by dieticians because of its endless benefits. The standard type we see in stores, named after Calabria in Italy, is planted in the middle of spring and produces big green heads. But broccoli is such a wonder that you can use every part of this plant! This is why nowadays, many people want to learn how to grow broccoli from seed.
Even though this vegetable is considered the public enemy for most people because it’s the number one diet item, I am a big fan of it. This vegetable you can work wonders with is filled with fiber, vitamins, minerals, potassium, iron, and folic acid. Even though it takes a bit longer to mature, in my opinion, the outcome and benefits of it make broccoli a worth-to-wait product. Thus, I believe that learning how to grow broccoli from seed is both fun and advantageous.
With that being said, broccoli is a quite simple vegetable to grow in a backyard garden or on the balcony. Although it enjoys warm temperatures, it can also tolerate a little bit of a chill too. Besides, to get the seeds ready for planting, there is nothing extra you need to do. No nicking or cold stratification is required. Nonetheless, there are several actions you can take to guarantee their germination and perhaps even hasten the process a little.
The Right Time to Grow Broccoli
Since broccoli is a cool season crop, the best time to start growing it is early to mid-spring, but of course, you also have to consider the climate of where you live. This way, you can harvest your fresh broccoli in early summer or late summer. Now, if you think that the harvest season is not important, you are wrong.
This is because it’s important to get broccoli to mature before or after high temperatures are anticipated since high temperatures will impact the development of the plant’s head, which is the harvestable section. And even though broccoli seeds can germinate in the soil as cold as 40°F (4°C), warmer soil is necessary if you want to hasten their growth.
You can start the plant indoors or outdoors before your area’s latest spring frost date. For a summer harvest, you can start your seeds indoors 4 to 6 weeks before the last frost date, and for a fall crop, it is advised to start in late May or early June. Even though the exact months can differ in different regions, you can typically begin your growing period six to eight weeks before your last day of frost.
Just remember, it’s critical to comprehend the timing requirements. If you start your seeds too early, you’ll get thin seedlings, which can grow into floppy, weak adult plants. The plants will wither in the hot summer temperatures if you start the seeds too late. Spring is the greatest time to plant broccoli because it thrives in cool climates.
How to Plant Broccoli
Broccoli is a cool-season crop that can germinate in the soil as cold as 5°C. As it does best in cool conditions, autumn planting is recommended if you reside in a warmer area. And if you want to plant seeds in your garden directly, remember that the soil depth must be approximately 1 cm, and it’s recommended to do it 85 to 100 days before the first autumnal frost that typically occurs there. You should be able to transfer out of seed trays after 4-6 weeks of growth.
One of the most important steps of planting this vegetable is to space your seeds out to allow for the healthy, large growth of the heads. Broccoli is a plant that needs space, so be careful not to crowd your plants. To thin out seedlings, you can space them 20 to 30 cm apart. Because if they are close to one another, they will compete for nutrients and water, making them more vulnerable to disease and pest problems.
The secret to flavorful broccoli florets is to space out your plants because the more room they have, the bigger the heads can get. Still, if you don’t have enough space for it, this vegetable can also be grown in pots or containers. But again, you should only put a few plants in each one to avoid competition for space and possible diseases. And if you will growing broccoli near other plants, avoid planting them near tomatoes, eggplant, and strawberries!
How Long Does It Take to Grow Broccoli From Seeds?
Broccoli is often a slow-growing plant; maturation might take between 50 and 100 days, depending on the variety. To maintain consistent soil moisture, you need to water them frequently, especially if there is a drought. Although certain varieties of it can resist heat, they all need appropriate moisture.
Avoid letting your broccoli plants become too dry in between waterings, as this may cause the stems to become harsh and inedible. To grow deep roots, give them around 3 cm of water every week and water them thoroughly. You can also use mulch to lower soil temperatures, preventing weed development. Fertilize once a month to encourage gradual, steady growth.
Is Broccoli Easy to Grow From Seed?
Broccoli is somewhat a contradictory vegetable. Although it is a sun-loving plant that despises shade, it is a cold-hardy plant that flourishes in colder climates. And to be successful on your broccoli growing journey, there are some key points you have to be careful about, including watering your plants every day to maintain the top 6 inches of soil moist at all times and making sure they get enough sun exposure.
Also, to prevent the water from evaporating too quickly, you can try watering in the early morning or late at night. If you are already familiar with growing vegetables from the seed process, I believe you can easily learn how to grow broccoli from seed, as well. Besides, if you start your seeds indoors, all you need is just some basic equipment. In short, just knowing the key points and being a little patient is enough to grow this vegetable.
Can You Plant Broccoli Seeds Directly in the Ground?
Yes, if you reside in a warmer region, you technically have the option of straight sowing the seeds right into your garden. However, there are still some things that you should pay attention to when doing this. And first and most important is to choose a spot for direct sowing that receives at least eight hours of sunlight. Also, you must make sure that the soil is loose, well-draining, and treated with 4-6-3 or 10-10-10 (NPK) fertilizer.
Another important point, as we mentioned before, is the spacing. Cultivators recommend planting two seeds per hole, 18 inches between them and in rows apart from each other by 24 inches. After this, it’s essential to keep your plants moist and be gentle when watering. So you can use a spray bottle to keep the area moist until germination occurs.
Approximately 10 to 21 days after this, you will see seedlings emerge. At this stage, thin each planting area until each contains only one seedling. You can begin cutting spears of your plant about 12 weeks after seeding, depending on the kind you’re growing. Cut the primary, central head first; this will cause the side shoots to sprout. After that, continue regularly cutting side shoots for the following four to six weeks.
If you are transplanting in Fall, make sure to find a space that receives direct sun and rich, moist organic soil. Just turning the soil under to a depth of 8 inches will be enough to prepare the bed. Create a sufficiently large hole for each plant to hold the root ball. Remember, plants should be placed in rows spaced 1-2 feet apart.
To promote healthy root growth, gently remove the plant from its pot and carefully use your hands to release the root ball. Set the top of the root ball to level with the dirt around it. Up to the top of the root ball, cover with soil. With your hand, forcefully press the earth. After it’s done, don’t forget to plant a tag on its location to avoid possible confusion.
Does Broccoli Grow Back After Cutting?
How often can a single broccoli plant be harvested and whether or not it can grow again after being harvested are two of the most common questions that come to mind when learning how to grow broccoli from seed. After all, you want to know how fruitful your efforts will be, which is only natural.
So, you already know that the main broccoli head typically grows on the plants for between 90 and 100 days. Once this head has been removed or harvested, the plant can no longer create another main broccoli head. Luckily, however, the plant can still produce some tiny sideheads. Therefore, receiving a second one is still possible after the initial harvest.
However, know that these will be in the shape of smaller heads that will sprout from the side of the larger one. The side heads that grow around the main broccoli head will be considerably smaller than the original head, however, the original or main heads are often larger in size and range in diameter from 4 inches to 7 inches (or 10 cm to 18 cm).
That said, if you want to receive the second harvest, it’s crucial to be careful when harvesting the first batch. Because the likelihood of a second harvest could be diminished or even eliminated if the main head is improperly trimmed or harvested during the first harvest. And for this, you must first ensure your broccoli head is prepared for harvest. Start by examining the size of the broccoli’s main head.
Conclusion
Although growing broccoli at home can be a little challenging, if you take good care of it and grow it in the appropriate conditions and at the right time of year, you won’t ever need supermarket broccoli again! Because being able to grow this vegetable at home is also very pleasant and an amazing way to save money without having to cut down on your nutrition intake. You can buy enough seeds to supply your refrigerator and freezer with fresh broccoli for a whole year for only a few dollars.
And your harvest will be ready between 50 to 100 days; this also depends on your type. However, regular fertilization can hasten the process and produce a larger crop. Still, it should be noted that the germination and survival rates are often much greater when seeds are placed indoors, and growing conditions are monitored and regulated for the first several weeks.
If you have a greenhouse, you can start planting your seeds there as early as late winter in tiny pots or modules. If not, as we previously mentioned, it’s recommended to start planting in early spring. But in this case, you might want to cover your crops with a net since birds can harm them by trying to feed on immature seedlings. With that being said, note that to maximize the vitamins and minerals in this vegetable, it is ideal to use the harvest as soon as it is picked.
