When to Sow Balloon Flower Seeds? A Detailed Guide to the Best Sowing Time

Balloon flower is a common flowering plant whose blooms are shaped like bells, and many people grow it, so when should balloon flower seeds be sown?

1. When to sow balloon flower

Winter sowing is from November to January of the following year, and spring sowing is from March to April. Winter sowing is preferable, and broadcast sowing is generally used. When sowing, mix the seeds evenly with moist fine sandy soil (ratio: 0.3kg of seeds mixed into 1 pot of soil) and scatter it over the surface of the bed, then lightly sweep it once with a broom until the seeds are no longer visible (that is, covering with soil to a depth of about 2.5-3 mm), and press lightly. In the following spring, the seedlings emerge early and evenly. For spring sowing, to achieve even emergence, the seeds must be treated, or the bed must be covered with straw after sowing to retain moisture (treatment method: soak the seeds in warm water at 30°C for 8 hours, remove them, wrap them in a damp cloth, place them in a spot at 25-30°C, cover with a damp hemp cloth on top to promote germination, and rinse with warm water once a day. After about 5 days, once the seeds begin to sprout, they can be sown). The sowing method is the same as for winter sowing, keeping the soil moist at all times; seedlings generally emerge in about 15 days. The seeding rate is 2.5kg per mu.

2. Balloon flower cultivation techniques

1. Raising seedlings: Balloon flower seedlings are generally raised and transplanted from April to June. Too early, and the small seedlings affect seedling quality; too late, and the large seedlings affect transplanting. The seeding rate is generally 10-12kg per mu (some experimental plots use 15kg). Specific method: choose land that is neither on a high slope nor in a low-lying field; it is best to choose a field with good drainage. The soil should be carefully tilled, with plenty of base fertilizer applied, preferably deep-plowed to more than one and a half chi, and the bed surface leveled so as to allow sprinkler irrigation during drought. Then mix the balloon flower seeds with fine soil and broadcast them evenly, press lightly on top, cover with weeds, and keep the soil moist. Seedlings generally emerge in 10-12 days. After the seedlings have emerged completely, remove the covering on a rainy day to benefit seedling growth.

2. Transplanting: The growing period is 1 year. It is carried out from autumn and winter of the same year to before sprouting in the following spring. Select 1-year-old straight-rooted balloon flower seedlings, grade them by size, and plant them separately. When planting, on the prepared planting ground, open furrows 25cm deep at a row spacing of 20cm, then insert the balloon flower seedlings diagonally into the furrows at a 75° angle, at a plant spacing of 6-8cm, cover with soil and press firm; the soil cover should be slightly higher than the seedling crown by 3cm.

3. Weeding: After the balloon flower seedlings emerge, weed them. When the seedlings have 4 leaves, thin out the weak seedlings; when they have 6-8 leaves, thin to a stand at a plant spacing of 1-2 cun, and when the soil is suitably dry or moist, carry out shallow loosening of the soil, keeping the ground loose at all times and the field free of weeds.

4. Drainage: Balloon flower is planted at high density and fears waterlogging. Therefore, during the hot and humid plum rain season, trenches should be cleared and drainage carried out promptly to prevent water accumulation from rotting the roots.

5. Flower removal: The flowering period of balloon flower lasts as long as 4 months, and flowering consumes a considerable amount of nutrients and easily triggers side branches. Therefore, removing flowers is an important measure to increase balloon flower yield.

Balloon flower is very fresh and elegant, very suitable for home growing and viewing, and after the balloon flower blooms are picked, they can also be made into cut-flower arrangements, with very high ornamental value.
