Planting burdock root seeds (Growing burdock gobo root from seed) – Arctium lappa burdock growing
How to grow burdock gobo root (arctium burdock) in soil culture. Last time, I added fertilizer to the field and prepared the soil for the arctium lappa burdock. About two days have passed since then. This time, I will plant the burdock gobo root seeds. (Growing greater burdock root from seed.)
When to plant burdock root (arctium lappa burdock) seeds? The time for planting burdock gobo root seeds depends on the variety, but it can be from around mid-March to mid-September. Burdock root (arctium lappa burdock) has a wide planting season, so it can be grown with spring planting or fall planting.
https://www.vege-try.net/en/prepare-field-for-burdock-root-e...To plant burdock root seeds, first make 4 holes in a plot of about 60cm x 70cm (23.6 inches x 27.5 inches). The space between burdock gobo plants is about 30-40cm (11.8-15.7 inches).
Burdock leaves grow quite large, so if you have enough space, keep about 50cm (19.7 inches) between the plants.
Use a mulch cutter to cut only the plastic on the mulch surface.
I heard that burdock root grows better when the plants compete with each other, so I will plant 4 gobo plants in each hole. The hole diameter should be a bit larger, around 10 to 12cm (4 to 4.7 inches).
Sow 4 arctium burdock (greater burdock root) seeds per hole in the mulch. The depth should be about 5mm (0.2 inches). Since arctium lappa burdock seeds are small, use a toothpick or similar tool to push them to a depth of 5mm (0.2 inches).
After sowing the greater burdock seeds, cover them lightly with soil and press down with your hand. As for the amount of soil to cover the seeds, burdock gobo root is a light-favoured seed (photoblastic seed), so cover it lightly with soil. Since the planting depth is about 5mm (0.2 inches), sunlight should reach the seeds easily.
Covering with soil and pressing down is called firming, and it’s an important step in planting burdock (arctium lappa burdock) seeds.
Pressing down the soil helps the seeds and soil stick together. This allows moisture in the soil to reach the seeds better, making it easier for them to sprout. Firming the soil also reduces moisture evaporation, preventing the seeds from drying out.
Water the soil to the point of moisture. (Be careful not to overwater, as it can cause the seeds to rot.)
Burdock gobo root (arctium lappa burdock) seeds are planted shallow, so be careful with the water pressure when watering. If using a watering can, turn the spout upward and water from a higher position. (Adjust how you water by checking how wet the soil is.)
If the water flow is too strong and the burdock root seeds might get washed away, cover them with a non-woven fabric and water on top of it.
Lastly, I set up a shade where the burdock seeds were planted. The reason burdock needs shade is that when planted in August, the temperature is a bit too high for sprouting.
The best temperature for burdock root to sprout is around 20–25°C (68-77 ℉). In July and August, when burdock seeds are planted, there are many days when the temperature is still over 30°C (86 ℉), which is a tough condition for the arctium burdock seeds.
When the temperature is over 30°C (86 ℉), the sprouting rate of burdock root gets lower, and you might need to plant the seeds again. So, I set up a shade to lower the risk of sprouting failure.
The shade is simple, so it’s easy to set up. I use four poles that are 90cm (3 feet) long and 1.1cm (0.4 inches) thick, some perforated plastic mulch, and four clothespins. Just put the poles in the burdock root plot and cover them with the plastic mulch, and the shade is done.
With this, the burdock gobo root seed planting is done.
