Suitable time for sowing pyrethrum

Pyrethrum is a perennial plant in the Asteraceae family. It can usually grow up to 60 cm in height. It mainly relies on seeds for reproduction and propagation. It usually blooms about four months after sowing. Its peak flowering period is from May to August each year.

Pyrethrum can be sown in the autumn of the current year or the spring of the following year, and the best time to plant it is mid-to-late February. At this time, the temperature begins to warm up, which is suitable for seed germination. After the sprouts grow, there will be a lot of precipitation, which can provide good growth conditions.

Pyrethrum sowing method

1. Prepare the soil

Pyrethrum likes to grow in a humid environment. When preparing the soil, you can choose garden soil combined with sandy soil, which can not only make the soil layer moisturizing, but also allow the plant roots to breathe better.

2. Sowing and watering

Next, bury the pyrethrum seeds in the soil, and then pour in a certain amount of water to keep the soil at a high humidity, help the seed coat soften for better germination, and increase the germination rate and survival rate.

Key points and techniques for growing pyrethrum

1. Lighting

Pyrethrum is a light-loving plant that grows vigorously in an environment with soft and long-lasting lighting conditions. However, care must be taken to diffuse light to avoid direct sunlight on the plant, which may burn the stems and leaves.

2. Moisture

Pyrethrum has a high demand for water during its vigorous growth period, so you can water it more often. However, special attention should be paid to reducing watering during the seedling stage of the plant to keep the soil dry and avoid waterlogging and root rot.
